Lifeforms which have been living inside crystals for up to 60,000 years have been revived by NASA, raising hopes that alien organisms could be found in extreme environments on other planets.

Penelope Boston, the director of NASA's Astrobiology Institute, and her team have spent years exploring Mexico's Naica Mine in Chihuahua looking for extremophiles, which contain caves as large as cathedrals.

The mine is filled with giant gypsum crystals which look so extraordinary that when Dr Boston first saw a picture, she assumed it had was a Photoshop hoax. 

But more astounding, was that inside the crystals, tiny bugs were discovered in a state of 'geolatency' - where living organisms remain viable in geological materials for long periods of time. 

"Much to my surprise we got things to grow," said Dr Boston. "It was laborious. We lost some of them - that's just the game.  They've got needs we can't fulfill. That part of it was really like zoo keeping."

Around 100 different bugs, which were mostly bacteria, were found inside crystals, where they had been trapped for between 10,000 and 60,000 years. 90 per cent had never been seen before. 

The cave system sits above a large pocket of volcanic magma and is geothermally-heated to temperatures of up to 60C, which has led to astrobiologists dubbing it 'hell'. 

Most life could not survive there but scientists have discovered some organisms have evolved to feed on the sulphides, iron, manganese or copper oxide in the cave.

"They're really showing us what our kind of life can do in terms of manipulating materials," said Dr  Boston.

"These guys are living in an environment where there's not organic food as we understand it. They're an example at very high temperatures of organisms making their living essentially by munching down inorganic minerals and compounds. This is maybe the deep history of our life here."

Describing working in the cave she said: "It was a transformative experience...it really felt strange. It was a very hard environment to work in, but tear-inducingly beautiful. It's like being inside a geode."

Some of the "sparkling white" giant crystals are as long as five metres. 

"I can't even put my arms round the biggest ones," she added. 

Other caves detected with "weird life forms" but accessing them was too dangerous.

Scientists said discoveries such as this raised the possibility that dangerous bugs could hitch a ride back to Earth when spacecrafts return from other planets.

NASA has plans to bring back rock and ice samples from Europa, an icy moon of Jupiter, which is one of the best targets in the solar system for life because it has a salty ocean beneath its crust.

Dr John Rummel, from the Seti Institute in Mountain View, California, said it was "pretty easy" for bugs to survive space journeys as long as they are shielded from the sun's ultraviolet radiation.

"If we bring samples back from either Europa or Mars, we will contain them until hazard testing demonstrates that there is no danger and no life, or continue the containment indefinitely while we study the material.

"It is assumed that such life would be hardy - to survive the trip to Earth; not easy -  and precautions taken would provide a very high degree of containment.

Naica's crystal caves hold long-dormant life

It is a remarkable discovery in an amazing place.

Scientists have extracted long-dormant microbes from inside the famous giant crystals of the Naica mountain caves in Mexico - and revived them.

The organisms were likely to have been encased in the striking shafts of gypsum at least 10,000 years ago, and possibly up to 50,000 years ago.

It is another demonstration of the ability of life to adapt and cope in the most hostile of environments.

"Other people have made longer-term claims for the antiquity of organisms that were still alive, but in this case these organisms are all very extraordinary - they are not very closely related to anything in the known genetic databases," said Dr Penelope Boston. 

The new director of Nasa's Astrobiology Institute in Moffett Field, California, described her findings here at the annual meeting of the American Association for the Advancement of Science (AAAS).

First opened by miners looking for silver and other metals a hundred years ago, the deeply buried Naica caves are a key interest to scientists fascinated by extremophiles - microbes that can thrive in seemingly impossible conditions.

The environment is hot (40-60C), humid and acidic. With no light at depth, any lifeform must chemosynthesise to survive. That is, it must derive the energy needed to sustain itself by processing rock minerals.

Researchers had identified microbes living in the walls of the caves, but isolating them from inside the metres-long crystals is a surprise. 

These outsized needles of gypsum have grown over millions of years. They are not perfect. In places they have defects - small voids where fluids have collected and become encased.

Using sterile tools, Dr Boston and colleagues opened these inclusions and sampled their contents. 

Not only did they detect the presence of bacteria and archaea, but they were able also to re-animate these organisms in the lab.

The concern would be that these organisms might simply be the result of contamination, either introduced by the team or the mining operations. But the Nasa director said that the necessary protocols were followed. 

Scientists have previously claimed to revive bugs thought to have been dormant for many millions of years. These organisms had been trapped inside salt or ice crystals. All such claims are contentious, but Dr Boston said she was minded to accept them after everything she had seen at Naica and in other similar environments.

What gives her confidence in the status of the Mexican caves is the great diversity of life that seems to exist there.

"Other groups have shown there are lots of viruses in these caves and what that says to me is that these are fully fledged microbial communities that have their viral load just like every other community does. So, that's another aspect of this that argues against casual contamination," she told reporters.

Working for Nasa as an astrobiologist, she is clearly interested in the relevance of such finds to the search for life beyond Earth.

"The astrobiological link is obvious in that any extremophile system that we're studying allows us to push the envelope of life further on Earth, and we add it to this atlas of possibilities that we can apply to different planetary settings."

Many scientists suspect that if life does exist elsewhere in the Solar System, it is most likely to be underground, chemosynthesising like the microbes of Naica.

Dr Boston said her team was about to submit a paper on the caves to a relevant journal. 

In her discussion with reporters she lamented the fact that the crystal complex had become flooded following the recent cessation of mining activities, preventing any further access.

"It is tear inducingly beautiful down there. I wrote several poems about it actually."

Raumfahrt - Indien will Energiebedarf bis 2030 durch Helium-3 von Mond decken

19.02.2017

Here's how India may meet its energy needs by 2030, thanks to the Moon

India can look forward to the Moon to fulfil all its energy requirements! 

 

The Sun has always been a source of energy for the world. But an untapped source of power may soon be able to meet all of India’s energy requirements. And that’s the Moon.

Sivathanu Pillai, a distinguished professor at the Indian Space Research Organisation (ISRO) stated that our country can meet its energy demands through Helium-3 mined from the Moon. By 2030, this process target will be met," Pillai said while delivering the valedictory address at the three-day ORF-Kalpana Chawla Space Policy Dialogue, organized by Observer Research Foundation.

The former chief of BrahMos Aerospace, Pillai also stated that lunar dust is rich in Helium-3 and mining it was a priority programme for the ISRO. "In a few decades, people will be going to the moon for honeymoon," Pillai said.

Other countries will also be working on the project. There is a lot of helium on the moon, which can suffice the energy requirement for the whole world. Creating low cost access to Moon and developing multi-purpose and reusable vehicles can also help in a big way - mining in planets and space tourism.

According to ANI, Lt Gen P M Bali, Director General, Perspective Planning, Indian Army said that the the launch of GSAT-7, India's first dedicated military satellite, is a testimony to the country's outlook towards using the outer space for the national security.

He also said that India has one of the largest constellations of communication and remote sensing satellites in the world and covers Asia Pacific. He says, “Although India continued with a civilian orientation to its space programme, it requires to develop military assets in space and on ground as an emerging regional and global power because of the changing regional and global realities.”

Luftfahrt - Bell V-280 Valor bei Vorbereitung für Flug-Test-Programm

18.02.2017

Bell V-280 Valor Prepping for Flight-test Program

bell-valor
 

In a well-guarded hangar tucked away on the Bell Helicopter campus at Rick Husband Amarillo International Airport in Texas, a tightly knit team of dedicated technicians and engineers is putting the final touches on Bell’s next-generation tiltrotor, the V-280 Valor. If all goes as planned, the V-280, which was about 93 percent complete in late January, will fly sometime around September this year.

Designed to fulfill a requirement for new cost-effective and more efficient aircraft for the U.S. Department of Defense’s Future Vertical Lift program, the V-280 is the U.S. Army’s Joint Multi-Role Technology Demonstrator (JMR-TD), “the flagship program anchoring the Army Aviation science and technology portfolio,” according to the Army. 

Bell leveraged its experience with the V-22—also built in Amarillo—in designing the V-280. Both share design features such as composite wings and other structural elements, but there are significant differences that are apparent when viewing the two aircraft. The V-22 is much larger and capable of carrying a maximum of 32 passengers plus at least three crewmembers, while the V-280 can fit 14 passengers and four crew. The Navy and Marines required a rear ramp for loading/unloading, which adds complexity and weight to the V-22, but the crew enter and exit the V-280 via six-foot-wide fuselage doors under the wings. Also adding complexity to the V-22 is the gigantic spherical bearing mounted under the center wing section and the folding proprotors, which allows the V-22 to fold into a compact and more easily stored unit. The V-280’s wing is fixed to the fuselage, and its proprotors are about a foot shorter than the V-22’s. 

Perhaps the biggest difference between the two aircraft is the way the proprotors tilt. On the V-22, the engines tilt up and down to provide the craft’s unique vertical lift and horizontal flight modes. The V-280’s engines are mounted in the nacelles and do not tilt. According to Bell, “The output shaft is connected to the drive system through a spiral bevel gearbox that transfers power to the fixed gearbox and proprotor gearbox, which rotates on two big spherical bearings driven by a conversion actuator mechanism.” The V-280’s tilting gearbox design vastly simplifies the V-22’s complex hydro-mechanical clockwork that provides the necessary tiltrotor action. 

The V-280’s powerplant configuration offers other advantages, explained V-280 build team manager Scott Allen. When the V-22’s engines point skyward during vertical flight, the exhaust is directed onto the landing area, and this could cause a fire, say on a grassy area, or damage a ship’s flight deck (the Navy uses protective pads under the V-22 exhaust blast). The V-280 projects only proprotor airflow downwards, while the engines remain fixed in place horizontally, eliminating the hot exhaust problem. Another benefit is that the pilot’s field of view is improved, with much less machinery blocking the view along the wings, he explained. 

Allen has been involved with the V-280 JMR-TD for four years, ever since it began as a preliminary design concept. Like Bell’s new 505 and 525, the V-280 was developed in Bell’s new digital design framework, which has helped keep costs down. The V-280 wing, for example, is estimated to cost less than half that of the V-22 wing, according to Allen. Designing the drawings for one of the V-22’s hydraulic systems took 700 to 800 manhours, compared to just 40 for the V-280. “Digital designs present huge opportunities,” he said. 

The program faced many challenges, but the hand-picked team of top Bell engineers and technicians has been able to solve every one. 

One challenge is because of the fixed wing mounting, which means that the V-280 will have to fly out of Amarillo, as it can’t be folded up like the V-22. Because of this, Bell had to build a ground-run stand, which features large ramps for the V-280 to roll up for installation in the test rig. The Amarillo Economic Development Corporation provided a $3 million grant to Bell to build the run stand.

While Bell built the V-280’s composite wing at its own facilities, the fuselage, made of aluminum frames and composite skins, was built by Spirit AeroSystems. The fuselage could eventually be all-composite, made using Spirit’s filament-winding machines, but that would depend on the Army’s level of comfort with composite structure. “I’d love to get to zero fasteners,” Allen said.

Flight control surfaces are composite, as are the proprotors. The V-280’s wing has 22 percent of the parts count of the V-22 wing; the V-22 wing is also more complex, with some dihedral that isn’t present in the V-280’s flat wing. Like the V-22, an interconnect shaft runs in the back of the wing, allowing either engine to power both proprotors in case of engine failure. 

The V-280’s landing gear configuration is also unique; basically, it’s a taildragger, with two main landing gear up front and a large wheel on the aft fuselage, and all are retractable. 

The empennage is a V-tail configuration, which some observers note is not the same as early drawings of Marine Corps V-280s with downward-tilting anhedral stabilizers. “That is one potential solution, but we haven’t evaluated it yet,” said Allen.  

bell-v-280-a

The V-280 is equipped with its own APU, mounted toward the top of the aft fuselage, and this can power utility systems and help start the aircraft’s GE T64-419 engines, each with more than 5,000 shp. The V-280 has three hydraulic systems running at 3,000 psi (compared to the V-22’s 5,000 psi), and up to two systems can fail while the remaining system powers the fly-by-wire flight controls. 

Last year, Bell demonstrated a sophisticated new cockpit concept for the V-280, a single-display touchscreen that fills the entire instrument panel. The touchscreen display has integrated night-vision and synthetic vision capabilities and allows the pilot to customize layouts of various kinds of information.

In the V-280 JMR-TD, the cockpit is more standard, with dual Lockheed Martin PFDs and MFDs and dual FMSs. The fly-by-wire collective and cyclic are a similar shape as the Bell 525’s, and they are mechanically interconnected to provide a visual cue of control movement for both pilots. 

V-280 specifications include a maximum speed of 280 knots, combat range of 500 to 800 nm, maximum self-deployable range of more than 2,100 nm and 13,000+ pounds of useful load.

UFO-Forschung - Sky and Stardust: The Flying Saucer in American Popular Culture, 1947–1957

.

John Sharples

Lancaster University

Introduction

This essay investigates the relationship between the flying saucer within post-war American popular culture and narratives of home, technology, and authority. As an object embodying a specific cultural moment, the flying saucer became a nodal point, a discursive centre, where discussion of aesthetics, power and modernity came together, projected into the minds of Americans via print media, advertisements, songs and material culture. As an alternative focal point of post-war culture to the atomic bomb, blue suede shoes or Marilyn Monroe, the flying saucer was a bright light cast against darkening skies, revealing an American audience look- ing optimistically towards a utopian future and guardedly back at the massive destruction of twentieth-century global conflict. As a ‘monster,’ this symbol of modernity possessed a certain plasticity of identity, evoking variously and non-linearly feelings of fear and fascina- tion, even playfulness. As an historical object, assessed in relation to technological and social change, the flying saucer eventually became thoroughly domesticated and acclimated within American society. Between Kenneth Arnold’s sighting which sparked national interest in the phenomenon on 24 June 1947 and the launch of Sputnik I on 4 October 1957, over 5,000 flying saucer observations were reported to the United States Air Force (USAF). In 1950, five or six sightings per day were logged,1 before spiking in 1952, when more flying saucers were spotted‘than at any time since the initial flood’in 1947, totalling 1,700.2 Reports became more sporadic in 1953 when only 429 sightings were received, subsequently declining further to ‘hardly more than a trickle.’3 Sputnik’s launch saw the flying saucer eclipsed to a degree as the generational other, taking its place within a genealogy of historical threats from above.

Historiography

The flying saucer has most often been viewed from its role in science fiction and cinema. Works such as M. Keith Booker’s Alternative Americas: Science Fiction and American Culture (2006)4 and Mark Jancovich’s essay ‘Re-Examining the 1950s Invasion Narrative’ (1996)5 have impressively covered the issue. Less well-considered has been the way popular non-fic- tional accounts of the phenomenon of the flying saucer questioned official, institutional and scientific explanations, inviting readers to participate in the debate, subverting accepted

power hierarchies. Also less considered has been how the flying saucer was viewed as both a returning or constant presence in the sky – a revival of pre-modern fears – and a symbol of modernity disavowed from tradition. This article situates these two issues within cultural approaches to unusual phenomenon relating to knowledge and meaning. Most pertinently, by describing the flying saucer as a monster, this essay employs methodological frameworks outlined by Jeffrey Jerome Cohen and Asa Simon Mittman, who have attempted to define the monster in relation to themes of otherness and human status. As such, use of the term monster suggests a specific relationship with the concept of domesticity and the limits of knowledge. A number of common methodological approaches have been outlined which take into account the physical appearance of the monster; its location; its process; and, most profitably, its challenge to common sense. Others begin with etymological definitions, high- lighting the origins of the word monster in the word men (an Indo–Iranian root) and hence memory, as well as, from St. Augustine, monstrare (to signify something out of the ordinary) and, from Cicero, monere (to warn).6 This approach is equally instructive, suggesting an interwoven, almost paradoxical, relationship between that which is ‘deviant, transgressive, threatening and therefore horrible, terrifying, and tremendous yet also astonishing, mar- vellous and prodigious.’7

More recently, however, the monster’s status as pure culture has been emphasized. In this light, the flying saucer possesses a specific relationship with a specific cultural moment. Monsters ‘proliferate in times of crisis. They are [often] born ... of a prevailing apocalyptic mood, usually triggered by political upheaval and threatening loss of control.’8 If the monster is ‘born as an embodiment of a certain cultural moment – of a time, a feeling and a place,’9 then the flying saucer ‘must be examined within the intricate matrix of relations (social, cultural, and literary–historical)’ which created it.10 Within the cultural space of its creation, the epistemological relationship between the flying saucer as monster and the frameworks of normative discourse became hazily delineated with relation to boundaries of familiar and unfamiliar. Equally, as products of a culture, the flying saucer should be viewed not as an outsider, but firmly within ‘the discursive arsenals of enlightened rationality.’11 Intercutting these two approaches, Terry Kirk distinguishes between institutional and popular forms of knowledge, whereby scientific knowledge ‘orders monsters in terms of relationships to nature's norms’ whereas, at a popular level, ‘monsters remai[n] culturally constructed repos- itoriesofsuperstition.’12 Althoughunguardeduseoftheterm‘superstition’isunwelcomein this context (appearing most commonly within flying saucer texts as largely derogatory or to pathologize belief), the point remains that reports on flying saucers, whether the prod- uct of a knowing posture or something else, frequently resisted the disenchantment of the world which ‘enlightened rationality’ supposedly brought about, both emerging from and challenging discourses of the individual, the home, and the nation in the post-war US.13

This divergence between popular and institutional knowledge can be framed less con- ventionally – namely as an interplay between two orientations of looking – up and down. Looking up, ‘watching the skies!’ in science-fiction parlance, suggests both an observational attentiveness, and a capacity for fantasy or day-dreaming. Looking down suggests, alter- natively, a grounded-ness, a down-to-earth-ness, or a myopic existence, with one’s head in the sand. The intermingling of these orientations is a critical part of the flying saucer story. The way the flying saucer raises connections between the impossible and the mundane has been noted in a number of works including Susan Lepselter’s‘Why Rachel Isn’t Buried In Her Grave: Ghosts, UFOs, and a Place in the West.’14 Lepselter considers ‘the leaps and boundaries

CULTURAL AND SOCIAL HISTORY 3

of UFO discourses, uncanny conspiracy theories, ghost stories, and tales of everyday life’ as well as the rural American West, focusing on narratives of class, loss, colonization and the body’s‘unmoored location in a world of accelerated technological change.’15 These issues, in part, surrounded the flying saucer in the period 1947–57. Particularly important is Lepselter’s emphasis on the primacy of personal, subjective experience, contrasting a shadowy ‘they’ of authority with a familiar, proximate‘us.’The conjunction of such thoughts with more down- to-earth matters confirms that the intermingling of the ‘fabulous and the real ... rises out of a shared imaginative and social field.’16

Part One: ‘I Know What I Saw’

In this story of elusive beginnings and endings, it was Kenneth Arnold’s sighting in June 1947, only weeks before the ‘Roswell incident,’ which established the flying saucer as a topical news story. Reports on Arnold’s sighting were significant in laying down the tonal and linguistic patterns of future accounts, and presenting an initial conflict between Arnold’s empirical evidence and the United States Air Force’s contradictions. The Associated Press on 25 June 1947, in an article headlined ‘Pilot Sees “Saucer-like Objects” Flying at 1,200 m.p.h. in Oregon,’ described how ‘nine, bright, saucer-like objects flying at “incredible” speed at 10,000 feet altitude were reported by Kenneth Arnold, Boise, Idaho pilot, who said he could not hazard a guess as to what they were.’17 ‘Call me Einstein, Flash Gordon or just plain crazy, but I know what I saw!’ Arnold remarked, whilst adding that what he had seen ‘seem[ed] impossible.’18 Butwhathadheseen?Theterm‘flyingsaucer’was,accordingtoArnold,19 aninventionofthe press, not Arnold himself (although he did use the term in a letter to air force intelligence) and the term in the media frequently resided in quotation marks, calling attention to itself and the gap between Arnold’s report and an imagined potential. Time headlined a 14 July 1947 article on the phenomenon ‘The Somethings,’ further suggesting an initial uncertainty about what was seen (or how to contain it in a pithy headline).20 Arnold referred to a saucer only to describe the movement of what he saw, that is, nine shapes which ‘flew like a saucer would if you skipped it across water.’21 In its linguistic construction, the term ‘flying saucer’ used to describe the uncanny repetition of the nine shapes linked together in the sky fell back on familiar terrestrial experiences.22 The term stuck, despite its dubious correlation with Arnold’s evidence. Demonstrating its infectious tendency, a Gallup poll of August 1947, only two months after first contact, revealed that 90% of those polled were familiar with the term or idea of ‘flying saucers’ or ‘discs.’ Later polls found the phrase more well-known than othertermssuchas‘ColdWar.’23 By1956,theterm‘flyingsaucer’wasinWebster’sDictionary.24

What did this naming convention imply? In part, a desire to connect what was seen to what was already understood through its connection to normal, human processes, born of an anxiety to explain and ‘the twin desire to name that which is difficult to apprehend and to domesticate (and therefore disempower) that which threatens.’25 If the monster is ‘the embodiment of difference,’26 then the term ‘flying saucer’ attempted to reduce or contain this difference by giving the object linguistic fixity. That is, naming a thing is a strategy of dealing with the unknown. As Jacques Derrida pithily put it, ‘a monstrosity can only be “mis- known” (méconnue), that is, unrecognized and misunderstood. It can only be recognized afterwards, when it has become normal or the norm.’27 The naming process was the first step towards normalizing the flying saucer which left no material trace beyond a psychological one, no visible sign of life but a radar blip, no sound but silence. Its sensory elusiveness and

the anxieties it embodied highlight the flying saucer as a monstrous object and, necessarily, an historical object, one understood through its impact or ‘challenging of cultural conven- tion and common sense.’28 Hence, the need for a name, albeit one Arnold claimed to be a misleading and inaccurate one.29

Indeed, Arnold claimed that he did not describe what he saw in terms of its appearance but only its movement. In an interview with Ed Murrow, he complained how, ‘they misquoted me ... Most of the newspapers misunderstood and misquoted [me]. They said that I said that they were saucer-like; I said that they flew in a saucer-like fashion.’30 Arnold’s disagreements stemmed in part from interpretation of the visual image of the flying saucer, specifically the sense of spec- tatorship it generated and the sensual immediacy of its outline and movement in the sky. That is, how does one interpret what one sees? W.J.T. Mitchell contrasts two modes of interpretation, namely that of ‘spectatorship’ and ‘reading,’ noting that ‘spectatorship (the look, the gaze, the glance, the practices of observation, surveillance and visual pleasure) may be as deep a prob- lem as various forms of reading (decipherment, decoding, interpretation, etc.).’31 Arnold’s report highlights the sensory immediacy of his sighting and its inability to be read appropriately. After all, how could one decipher something so seemingly outside cultural convention and normality? Instead, Nicholas Mirzoeff talks of a dimension to visual culture ‘at the heart of all visual events’ – ‘the undeniable impact on first sight that a written text cannot replicate ... the feeling ... that separates the remarkable from the humdrum ... this surplus of experience’ which evokes ‘admi- ration, awe, terror and desire.’32 This is not just a case of seeing is believing, but a submission to the sensory delight or dread which the image provided – a suspension of disbelief in part which re-enchanted the sky and rendered explanation supplementary. The name‘flying saucer’gave in to these aspects of spectacle, avoiding interpretation and submitting to emotion.

The visual, spectacular nature of the flying saucer which early reports highlighted remained a continuing feature of coverage within this period. Appearing on the front-page of the local newspaper The Times-News (North Carolina) on 23 May 1951, flying saucers were spotted over Kansas and Minnesota:

about 50 residents at the eastern end of Rainy Lake, near International Falls, Minn., said they saw a “crystal ball” which performed like “a huge humming bird” as it flashed across the skies. It was later joined by another “crystal ball.” And an American Airlines pilot said a “bluish white star played tag” with his plane at an altitude of 21,000 feet southwest of Dodge City, Kans. ... The Minnesota observers said their “crystal ball” dashed across the sky at speeds “in excess of 700 miles an hour,” then stopped suddenly and hung motionless above the lake. Then it shot upwards 200 feet in a split second, they said.33

The almost child-like quality of the ‘Lubbock Lights’ confirmed the representational strategies used to attempt to ensnare the flying saucer. In this ‘performance,’ the flying saucers adop- tion, and then defiance, of human or animal characteristics can be seen at work. Attempts to describe the shapes as ‘playing tag’ or appearing ‘like a huge humming bird’ broke down when faced with sudden movement and beyond-human (or bird) speeds. The arresting nature of the ‘flying saucer,’ its capacity to disrupt and stop everyday convention, was also seen in 1954, when AP reported how a light-show in Sand Springs, Oklahoma – ‘a mysteri- ous ball of fire that “darts up and down at the stroke of midnight” – ha[d] created a serious traffic problem ... For three straight nights police have found no less than 150 cars parked on the highway with their occupants gazing skyward.’34 Alternate headlines in other local newspapers declared ‘Mysterious Ball Of Fire Ties Up Oklahoma Traffic,’35 and ‘Flying Disc Jams Traffic,’36 as if reporting on road-works or a car accident.

CULTURAL AND SOCIAL HISTORY 5

Naming the flying saucer was one aspect of a strategy of containment for dealing with the ‘impact’ of its monstrosity. Emphasizing its playful aspects was a second. Yet, another strategy, highlighted by Arnold’s comments, attempted to link the saucer with contemporary technological progress, in short to confirm its historical status. By this measure, the flying saucer did not embody a total rupture with the past. In a letter to the USAF, Arnold described how ‘several former Army pilots informed [him] that they had been briefed before going into combat overseas that they might see objects of similar shape and design that [he] described and assured [him] that [he] wasn’t dreaming or going crazy.’37 Certainly, the flying saucer within much of the cultural material it generated existed between spaces, between time, as a ‘curious vision of modernity,’ and a totalizing object, disturbing attributes thought uniquely human. Modern life, post-war modern life, demanded new modern objects and new sym- bols. Yet, equally, the flying saucer appeared as one of several ‘curiosities that illuminate[d] something shadowy and forgotten behind the neat façade of a rational world, returning ‘enchantment, magic, and wonderment,’38 poised between rational scientific enlightenment and superstition. Ken Hollings’ Welcome to Mars (2008) records how the post-World War Two period was a space where the ‘fantasy of science’ including the flying saucer, alien abduction, brain-washing, and drug experimentation (willing and unwilling), appeared less imaginary, presenting fantasy as history and history as fantasy.39 Technology in this period seemed to close the gap between science fiction and reality. The flying saucer appeared on the boundary of this sci-fi life. It was not straightforwardly unbelievable within post-war American society, but instead poised on the boundaries of the possible. Early accounts of flying saucers were near ‘to the ragged edge of aviation technology.’ 40 Arnold, after all, had been piloting ‘an extremely high-performance, high-altitude airplane that was made for mountain work’41 when he saw the saucers. The Enola Gay had taken off from Roswell Air Force Base less than two years previously and Air Force Captain Charles ‘Chuck’ Yeager would break the sound barrier in the Bell X-1 rocket-powered plane on 14 October 1947. On May 1947, Mechanix Illustrated had the soon abandoned US Navy’s disc-shaped ‘Flying Flapjack’ on their front cover. Later tests of the machine attracted reports of flying saucer sightings,42 such was its radical break with the traditional airplane silhouette. To name but a few technological and bodily advances of the period 1947–57, the secrets of DNA were discovered; Everest was conquered; IBM’s electronic brain was announced; the transistor and microwave were invented; and Roger Bannister ran a sub-4-minute mile. In each case, bodily or scientific limits were extended.43

The flying saucer should not be seen, therefore, as a creation solely of the superstitious mind. Waldemar Kaempffert, reviewing ‘Those Strange Little Men; Flying Saucers,’ by sceptic Donald H. Menzel in 1953, misguidedly, believed that the flying saucers proved that science had not yet ‘seeped down into the multitude. A belief in witches, devils and evil spirits may strike drivers of automobiles and owners of television sets as amusing and pathetic,’ but the widespread belief in flying saucers and the ‘acceptance of tales of “little men” who were found in one that was wrecked are cut from the same pattern.’44 Yet, Kaempffert was guilty of another form of superstition, namely believing that that ‘the program of Enlightenment was the disenchantment of the world; the dissolution of myths and the substitution of knowledge for fancy.’45 Technological progress being mistaken for exorcisms of the past is, of course, nothing new. Even in contemporary, ‘modern’ society, these beliefs in what some term superstitious remnants have not disappeared.46 As Lepselter states, ‘uncanny discourses are stubbornly resistant to, yet inextricable from, modernity’s processes of rationalization

and disenchantment.’47 Kenneth Arnold was no uninformed, wide-eyed pilot and certainly the initial reaction, whilst occasionally mocking, did not suggest his report was inherently absurd. Other reports, at least initially, received an open-minded reception. When in 1950, for example, Life magazine48 published images of ‘Farmer Trent’s Flying Saucer,’ far from being seen as a superstitious individual, Life noted that ‘No more can be said that ... the man who took them is an honest individual and that the negatives show no sign of being tampered with ...’49 A letter to the magazine from a reader the following month did, how- ever, suggest the photographs were the result of a forgery and that Farmer Trent was more ‘dishonest’ than naïve.50

However the press or Arnold characterized the new agent in the sky, the flying saucer remained a symbol of modernity – a disavowal of the immediate past (in which we live) and the present (in which we never quite seem to live), a disavowal of the superfluous baggage of everyday life, as well as a gesturing towards the future. Disavowal, according to David Punter, is the ‘heart of the gesture of modernity: there may be all manner of ancestors beckoning back towards the past, but it is only by ignoring [or pretending to] or transcending their sireniac blandishments that the genuinely “new thing” can be discovered and valued’ or even invented.51 Regarding the flying saucer, these ‘ancestors’ consisted of previous, pre-Arnold sightings which were unsuccessfully dusted down to try and connect Arnold’s vision with a longer tradition of objects in the sky, again an effort which aimed at the domestication, or at least a disarming, of the saucers. Charles Fort’s accounts of objects in the sky, for exam- ple, were recorded and reclaimed by Relman Morin, of AP, in 1952, in an article headlined ‘Flying Saucer Found To Be Old Discovery – Reports Published 30 Years Ago; Some Go Back 100 Years.’52 Claims for Biblical sightings of the flying saucer were also made - ‘take Ezekiel Ten. A wheel within a wheel. What a fine description of a flying saucer.’53 Flying Saucers were an ‘Old, Old Story - Luminous Whatzits in Sky Have Been Seen Before.’54 These fragmented sightings - ‘a flying saucer scare in 1897, a great cigar-shaped saucer ... seen in 1882, and ... the Hebrew prophet Ezekiel witness[ing a] flying sauce[r]’55 – redefined the flying saucer as an historical object. Popular Science reported ‘Flying Saucers are Old Stuff,’ in 1952, again suggesting flying saucers were nothing new.56 A more convincing genealogical claim was found within the work of science fiction.57 Physicist Milton Rothman suggested that ‘the idea of space vehicles shaped like flying saucers was imprinted in the national psyche for many years prior to 1947,’ pointing to ‘the November 1929 issue of Science Wonder Stories, published by the legendary Hugo Gernsback. The cover of this magazine shows a spaceship that looks like a giant Frisbee, clutching in its tentacles a dwarfed Woolworth building.’’58 Historicizing took the form of looking backwards. Like any genealogy, history was read in reverse. Artificial chains of ancestry were imagined in an effort to give purpose, meaning and order to the flying saucer.

Posing a cognitive challenge, the flying saucer was a provocative object and an exotic body, defying, through its plane of movement, speed, and silence, the accepted conven- tion of flight. To talk of such an object as a ‘monster’ may seem odd. Traditional monsters in cultural criticism often possess a physical threat which the flying saucer, aside from in the movies, did not. Yet, ‘it is now clear that in many cultures ... monsters can be comic, even playful’59 (as the flying saucer undoubtedly was), whilst also possessing an unspoken physical threat beyond this. For Arnold, the matter was straightforward; what concerned him was not knowing, and insisting he was not‘crazy.’Hence, the flying saucer’s monstrosity – its impact – was ultimately ‘rooted in the vertigo of redefining one’s understanding of the

world.’ As Noël Carroll writes, ‘monsters are not only physically threatening; they are cog- nitively threatening. They are threats to common knowledge,’ which interrogate ‘our (their, anyone’s) epistemological worldview,’ defining ‘monstrosity from within, from a condition of normality which is altered.’60 The thread of a connection between the limits of human technology and the flying saucer only served to emphasize the disconnection between the two, since the latter did not ‘appear to depend on the same stresses and strains as the helicopter or jet plane do to get in the air. ... [I]t seem[ed] to swoop effortlessly down from above.’61 Its unearthliness seemed inimitable. Shortly after Arnold’s sighting, on 21 June 1947, one joker’s attempt to create a flying saucer – in an incident dubbed the Maury Island Hoax – was unmasked by the somewhat earthly debris and smoke trail the craft left behind.62 Its accordance to terrestrial chemical convention revealed it as less than spectacular, less than monstrous, and less than alien.

Instead, whatever Arnold or the media claimed, it was not movement or speed that define[d] the flying saucer, nor its shape, nor visual appearance of metallic lightness, of reflective surfaces that glinted and flashed, nor lack of sound, but its simultaneous escaping from the boundaries of everyday life and its connection to them.63 The notion of epistemo- logical rupture (signalled by the movement of Arnold’s sighting) was further emphasized by the unstable nature of the flying saucer’s form within popular culture. As one contemporary investigator of the flying saucer noted, the term flying saucer was ‘applied to anything in the sky that [could not] be identified as a common everyday object.’64 Soon after the initial sightings, ‘objects of every conceivable shape and performance’ were classed as flying sau- cers and the term ‘flying saucer’ became a broad term applied to, amongst other things, ‘a formation of lights, a single light, a sphere, or any other shape, and it c[ould] be any color, performance wise, flying saucers c[ould] hover, go fast or slow, go high and low, turn ninety degree corners, or disappear instantaneously.’65 Again this confirms Mittman’s observation that morphology is less important than ‘impact’ in the monstrous identity. The term ‘flying saucer’ expanded beyond any of its signifiers, describing a family of objects in the night sky with their unfamiliarity in common.66

Domestication of the flying saucer meant keeping its potentially more threatening aspects under control. Three disparate examples of this can be seen in advertisements which utilized the figure of the flying saucer and the alien visitor in 1952 and 1953. In the first, the introduc- tion of flying saucer pajamas for children was delayed ‘because stores thought the original design of an evil-eyed Martian might frighten young customers. The new design ha[d] only clouds, stars and saucers – but the saucers glow[ed] in the dark.’67 Nothing too threatening was permitted. As should be apparent, censorship stems from parents, not children, and the complaints about scary aliens are indicative of the projected fears of grown-ups. Reds under the bed were bad enough, never mind aliens within it. No doubt more wholesome was the Buck Rogers toy set, advertised alongside Sylvania TV sets – now ‘with Bigger Better-Than- Ever Halolight.’ Children whose parents sat through a demonstration of the television set were rewarded with free gifts including ‘eight flying saucers’ and, importantly, a ‘flying saucer dis- integrator.’‘Standing figures of Buck, Wilma, Space Rangers and Martians’ were also included. In the advertisement, the human heroes’ guns are being pointed at the aliens, who remain subdued and under control.68 Last, a full-page advertisement for ‘Statler Hotels’ depicted a Martian landing his ship and, in rhyme, through five panels, declaiming his amazement at the hospitality of the hotel. The alien, named Ooma Goo Goo, declares ‘I wish my wife and kids were here ... But then, alas, his time was up. With teardrops in his eye, “I’m coming back,”

he promised – and he vanished in the sky.’69 The (inspired) Mad Men who conjured up this idea carefully suggested in each panel the luxuries and earthly delights of the hotel. In these three cases, the flying saucer’s otherness is derailed by its association with human control or the practices of everyday life.

In the child-like displays in the night-sky, its appearance on children’s pajamas, in toy form, or in advertisements, the flying saucer provided a visual counterpoint to other technologi- cal performances of the period. The most notable of these – perhaps the most spectacular technological performance of any twentieth-century creation - was that of the atomic bomb, or more specifically, the mushroom cloud of the atomic bomb. As Carl Jung stated, in 1959 ‘the threatening situation of the world today’70 influenced the representations of the flying saucer - a threatening situation which, in large part, stemmed from ‘the bomb.’ Films such as The Day the Earth Stood Still (1951) made explicit the connection between the flying saucer and the Manhattan Project’s conjunction of political power and scientific force, as well as reminding one of the inter-textual nature of the object – wrapped up within a tradition of science-fictional texts. Yet, the two technologies inspired different feelings and emotions. Accounts of the atomic bomb suggest a horrifying spectacle – a much different account of monstrous technology than the flying saucer. Eyewitness accounts, for example, of the Nagasaki atomic bomb, dropped on 9 August 1945, described a multi-colour explosion – ‘a bluish-green light that illuminated the entire sky all around. ... [the sound] like the boom of cannon fire.’ In scale, the atomic bomb dwarfed its surroundings. Observers

saw a giant pillar of purple fire, 10,000 feet high, shooting skyward with enormous speed ... becoming ever more alive ... It was no longer smoke, or dust, or even a cloud of fire. It was a living thing, a new species of being, born right before our incredulous eyes. ... it was a living totem pole, carved with many grotesque masks grimacing at the earth ... struggling in an elemental fury, like a creature in the act of breaking the bonds that held it down.71

Such violence of language is not seen within flying saucer accounts which largely evaded the inherent violation of sensory communication. Indeed, describing the atomic bomb as a monster ‘represents a typical post-war way of conceptualizing the atomic bomb as a pri- meval creature. In early reactions to its use, references abound to the atomic bomb as a “Frankenstein monster.”’72 The bomb remained an outsider. It held no promise of a utopian future. It was made without constraints of responsibility. It was ‘an incorporation of the Outside, the Beyond – all of those loci that are rhetorically placed as different and distinct but originate Within.’ Whilst, ‘through the body of the monster fantasies of aggression, domina- tion, and inversion are allowed safe expression in a clearly delimited and permanently liminal [science-fictional, almost imagined] space,’73 the atomic bomb’s monstrosity, in contrast to that of the flying saucer’s, particularly after the acquisition and testing of the technology by the Soviet Union in late 1949, ‘gave way to horror ... when [it] threaten[ed] to overstep these boundaries, to destroy or deconstruct the thin walls of category and culture.’ 74 No one, to state the obvious, ever described a mushroom cloud as playful.

Although the playful aspect to the event described below balanced out its potentially more terrifying aspects, that the flying saucer’s monstrosity was of a different order, yet in some instance, connected to the visual icon of the atomic bomb, was made apparent can be seen in accounts of a July 1952 incident when strange lights were spotted over the White House. This was not the opening line of a science fiction story, but rather one of the more famous flying saucer incidents, symbolically intertwining the flying saucer with con- cepts of Home and Homeland - a threat to one was a threat to all. The two would become

increasingly commingled in the following decade. Truman’s 1947 State of the Union had after all called for both a ‘continuation of an aggressive program of home construction’ and stated that ‘our goal is collective security for all mankind.’75 As William J. Levitt remarked, ‘no man who owns his own house and lot can be a communist. He has too much to do.’76 A home, and especially to own a home, was a marker of the physical and mental health of a nation. An attack on the White House, as in so many science-fiction films, symbolized an attack on American values and the gleaming balls of light over Greek Ionic architecture formed a powerful image. The linguistic conformity of responses to the lights is striking and substantially different to eyewitness accounts of the atomic bomb. On 19 July 1952, one observer, Harry Barnes noted that, ‘we knew immediately that a very strange situation existed ... their movements were completely radical compared to those of ordinary aircraft.’77 Airman William Brady stated he saw an ‘object which appeared to be like an orange ball of fire, trailing a tail ... unlike anything I had ever seen before. ... [it] took off at an unbelievable speed.’78 Staff Sgt. Charles Davenport’s description emphasized how light ‘would appear to stand still, then make an abrupt change in direction and altitude.’79 A Captain of an airline flight described ‘odd lights.’80 A ‘stunned silence’81 was one recorded response. Cedar Rapids Gazette, Iowa, in language reminiscent of insect invasions or biblical plagues, headlined its report ‘Saucers Swarm Over Capital.’82 Jet fighters were placed on alert with orders to shoot the saucers down. The scientific detachment of reports to the public was replaced by a more traditional reaction to the threat of invaders. On 24 September 1952, it was admitted that ‘the flying saucer situation ... ha[s] national security implications ... the potential for the touching-off of mass hysteria and panic.’83 At the same time, the performative quality of the display was appreciated by Life who wrote how ‘the unidentified blips were bounding all over and performing most remarkably. Some seemed to hover idly, some reversed them- selves back and forth, others sped along making right and left ninety degree turns.’84 This even stretched into comedic tone. That the ‘authorities’ who had dismissed the reports of flying saucers for five years were chasing shadows and radar blips provided a darkly ironic commentary on the whole flying saucer phenomenon.

Part Two: ‘It was a strange time ...’

‘Belief in alien visitors from other worlds via spacecrafts,’ states Peter Dendle, ‘is a hallmark of the twentieth- and twenty-first centuries, especially in the post-war period: it is a signature folklore of the technological age.’85 In Dendle’s opinion, aliens serve a similar role to that of Bigfoot, ghosts, angels and gods: to surround and accompany us.86 As an all-encompassing narrative, this is not a bad one. Yet, the notion that belief in flying saucers was a reaction to a feeling of cosmic loneliness strikes one as odd, particularly when the texts describing flying saucer sightings were so playful and often humorous.87 More useful is Dendle’s notion that whilst the discourse surrounding ‘alien visitation is conspicuously intertwined with govern- ment conspiracy,’ concerning the concealment of knowledge, ‘it is not simply that belief in aliens requires a subsequent mistrust of government; rather ... the monster [has] become a vehicle for active resistance to authorities perceived as sole proprietors and dissemina- tors of human knowledge.’88 It is to this former aspect towards which this essay now turns, particularly the way ‘mistrust’ manifested itself at the popular level.

As suggested, Kenneth Arnold’s initial account was met with disbelief by military and aviation authorities. An Associated Press newspaper account, dated 26 June 1947, recorded

how ‘Army and Civil Aeronautics Administration spokesmen expressed scepticism ... over’ Arnold’s report, remarking that ‘nothing flies [as] fast [as Arnold’s alleged saucer] except a V-2 rocket, which travels at ... 3,500 miles an hour.’89 Over the decade, numerous government reports investigated flying saucers. Project Sign, Project Saucer, Project Grudge, and Project Blue Book successively attempted to unravel the mystery Arnold had provoked. More perti- nently, Arnold’s sighting established the flying saucer as a site of debate between institutional or scientific knowledge and the accounts of laymen or the popular press. Government- approved reports and scientific explanations from the likes of Donald Menzel, when finally released, found little support within a section of the sceptical popular press and print media which had seized upon the saucer as an ongoing story ripe for commercial exploitation and playful manipulation, eluding or ignoring government and institutional boundaries. In the same vein, a whole host of works regarding the flying saucer emerged, purporting to be written by ‘experts’ on the phenomenon. The most pervasive of these accounts was perhaps Donald Keyhoe’s The Flying Saucers Are Real (1950) – a work concerning reported UFO encounters between 1947 and 1950 and ‘the first influential attempt to promote the idea of “flying saucers” as alien spacecraft.’90 In outlining the reaction to such encounters by the United States Air Force, Keyhoe believed that there was a policy of gradual revelation whereby the USAF would only reveal the truth concerning the existence of extra-terrestrials when it thought appropriate, redefining the period as a liminal state between sighting and revelation. Keyhoe’s principal evidence was an extract from a 1947 United States Air Force document entitled ‘Project “Saucer” Preliminary Study of Flying Saucers’ which stated that ‘the saucers are not jokes. Neither are they cause for alarm .... [In light of human technological progress], ‘we should ... expect at this time above all to behold such visitations.’ Despite this initial claim, later sightings were met with denial by the USAF, or explained away as mete- orological phenomenon. Much of Keyhoe’s work concerned the motivations and contradic- tions he believed were present in these institutional responses. ‘I have carefully examined, he stated in 1950, ‘all Air Force saucer reports made in the last three years. ... I believe that the Air Force statements, contradictory as they appear, are part of an intricate program to prepare America – and the world – for the secret of [flying] disks.’91

Keyhoe’s account set up a shadowy ‘they’ against a familiar ‘we,’ feeding on the undercur- rents of paranoia (as a cultural symptom) which technological threats to security generated. As Cynthia Hendershot stated, ‘In the Atomic Age, there is no place to hide’ and ‘The very pervasiveness of the threat makes paranoia the ideal system for expressing fear ...’92 Yet, in The Flying Saucers are Real, the USAF, not the flying saucers, are the enemy. That the account reads more like a conspiracy thriller – it is written in first-person, noir-adventure style - only adds to the subjective, paranoiac nature of Keyhoe’s work. Equally, the mundane nature of much of his investigation contrasts with the extraordinary suspicion he possesses. One sec- tion, for example, begins, ‘It was a strange time. I picked up the telegram from my desk and read it a third time.’ In this passage, the act of searching for the secret of the flying saucer has transformed even everyday tasks such as reading one’s communications and letters into a ‘strange’ experience, emphasized by the banal repetition of ‘time.’ Like a post-war, science-fic- tional Philip Marlowe on the hunt for a life-changing treasure, Keyhoe characterized his adventure as an uncovering of the truth. He noted in the introduction to The Flying Saucers are Real, how he had ‘tried to show the strange developments in [the] search for the answer; the carefully misleading tips, the blind alleys ... entered, the unexpected assistance, the confidential leaks, and the stunning contradictions.’93 In March 1954, the Air Force position

CULTURAL AND SOCIAL HISTORY 11

was still that ‘“given enough factual data” every “flying saucer” report over the last six years could be explained in natural, earthly, non-sensational terms.’94

By contrast to Keyhoe’s labyrinthine story of misdirection and concealment, institutional accounts of the flying saucer myth presented the flying saucer story in an understandable, logical, and linear manner, attempting to reduce the object’s monstrosity. Press releases were given out with ‘meaning fixed and pre-determined so that the reader [wa]s a site merely to receive information. ... [whilst obscuring] any elements that would open up the text to multiple meanings,’95 whereas participatory investigation such as Keyhoe’s, placed the reader ‘in a position of control, tak[ing] an active role in the construction of meaning. ... [replacing stable meaning] by a proliferation of meanings and a disregard of narrative structure.’96 Donald Menzel’s writings, for example, explicitly sought to shut down debate on the matter outside of a scientific tradition. In Look magazine in 1952, he wrote on ‘The Truth About Flying Saucers,’ asking why ‘have so many civilized people chosen to adopt an uncivilized attitude toward flying saucers?’ Answering this, he suggested that people ‘naturally attribute mystery to the unusual;’ people are ‘all nervous. We live in a world that has suddenly become hostile. We have unleashed forces we cannot control; many persons fear we are heading toward a war that will end in the destruction of civilization;’ and that ‘people enjoy being frightened a little.’ Menzel stated that ‘balloons, papers, distant planes, Venus and the like’ accounted for the majority of sightings and ‘an optical phenomenon’ for the rest. Amusingly, if unnervingly, Menzel ended by suggesting that ‘You, too can have flying saucers in your home. Perhaps not as elaborate as the ones I have just described, but nevertheless adequate to demonstrate some of the effects. You may simulate the gradual bending that causes a mirage by using a sharp reflection at a water surface.’97

In a different type of participatory mode, newspapers invited reader theories and sub- jective interpretation replaced objective analysis and traditional forms of knowledge pro- duction. Life’s 9 June 1952 article on ‘the case for flying saucers,’ for example, rather than close off interpretation, instead ‘provoked a tremendous barrage of letters. Some have been nonsensical,’ noted the editor, ‘some philosophical, some have contained provocative and plausibletheories....[T]hestorypromptedanunprecedentedresponsefromthereaders.’98 Continuing, Life stated that ‘readers can aid the search ... by reporting the sighting of any strange aerial objects to the nearest Air Force representatives.’99 On similar lines, although to different ends, Ralph Steiner’s ‘How to Expose Flying Saucers,’ Popular Science, January 1953, urged readers to help expose flying saucer sightings as simple scientific phenomenon. ‘You’re invited,’ ran the piece, ‘to join the Air Force’s new project for studying saucers ... you, too, can join the hunt.’100 When, in 1951, the USAF had tried to explain sightings as ‘only plastic balloons, used by the Navy in the study of cosmic rays,’ the reaction was incredulity. Whilst various authority figures suggested that if only the public had listened to them, they would receive enlightenment and ‘that the public had preferred myth to fact,’ this ignored the conditions which had contributed to the widespread popularity of the flying saucer as a cultural object. Dr. Urner Liddell claimed that ‘nobody seemed to want to believe us’ and Dr. Robert A. Millikin that ‘everybody with any intelligence knew all along that the flying saucer speculationswerehooey....thepublicwantedsomethingsensational....’Morelegitimately, Frank Scully could still ask, ‘Why should we believe the Navy this week since they are con- stantly blowing hot and cold?’101

Further, in response to another report on the sightings, Life’s 7 April 1952 edition, with no-less a cover star than Marilyn Monroe, posed the question ‘Have We Visitors From Space?’

Giving a sceptical response to previous official investigations into the flying saucer contro- versy, the article described how Project Saucer and Project Grudge ‘seemed to have been fashioned more as a sedative to public controversy than as a serious inquiry into the facts. ... On Dec. 27, 1949,’ they continued, ‘after two years of operation, Project Saucer wrote off all reports of unidentified aerial phenomena as hoaxes, hallucinations or misinterpretations of familiar objects – that is, all but thirty-four. These stubborn thirty-four, seemingly unex- plainable, were briskly dismissed as psychological aberrations.’102 The article followed this with a series of conclusions, first suggesting ‘what they [the thirty-four sightings] [we]re not’ and what they may be. ‘They are not,’ it stated, ‘psychological phenomena. ... They are not a Russian development. ... They are not distortions of the atmosphere resulting from atomic activity. ... They are not all Skyhook balloons.’103 In its sceptical conclusion, the author asked,

Who? What? And When? ... the real depths of the saucer mystery bemuse penetration, as the night sky swallows up a flashlight beam. What of the other shapes? Why do the things make no sound? How to explain their eerie luminosity? What power urges them at such terrible speeds through the sky? Who, or what, is aboard? Where do they come from? Why are they here? What are the intentions of the beings who control them? Before these awesome questions, science – and mankind – can yet only halt in wonder. Answers may come in a generation – or tomorrow. Somewhere in the dark skies there may be those who know.104

This conclusion was, in many ways, the highpoint of healthy scepticism and an astonish- ing position for the respectable, middle-class periodical to take, marking something of a turnaround from a 1950 Life article, entitled ‘Out Of This World,’ where the author wistfully remarked on how ‘in a way we could wish that the tales of the interplanetary visitors were true. In the past the unification of peoples has seldom occurred, short of conquest, unless they were confronted with a powerful and potentially menacing outside enemy.’105 Rather than following the official reports based on detailed investigation by the USAF over a period of years, Life chose instead to side with personal, subjective experience, linking sightings with the technological optimism of the era and the anxiety which such technology could provoke.

Readers of the flying saucer problem were hence presented with a range of explanations. In a market place of ideas, one could choose one’s own interpretation. In an ‘unofficial’ poll for the sceptical Popular Science in August 1951, eyewitnesses to flying saucers were asked what they thought they saw, concluding that ‘the experts can say what they like, but a lot of people who saw “flying saucers” have made up their minds for themselves.’ A majority – fifty-two percent - believed they ‘saw “man-made aircraft,”’ sixteen percent believed they ‘saw “some- thing commonplace,”’ four percent believed they ‘saw a “visitor from afar”’ and two percent were‘uncertain.’106 The way the flying saucer was a contested space mirrors Susan Lepselter’s comments on collective accounts of alien abductions as ‘a jumble of echoing returns.’107 As early as July 1947, some were experiencing ‘explanation fatigue.’ Billboard commented that ‘with almost everyone coming up with a so-called solution to the flying saucer mystery ... 2 More Solutions To Flying Saucer Puzzle Won’t Hurt.’108 Certainly by 1957, the tone had shifted, again seen through coverage in Life. Reporting on the Interplanetary Space Convention near Giant Rock Airport near Yucca Valley, California, the reporter found ‘1,200 earthlings [gathered] to reaffirm their unshakeable belief in the existence of flying saucers.’The cult-like properties of this gathering were evidenced by the desert setting that looked like ‘a lunar landscape’ and the recitals of saucer stories by each devotee to the larger group. A sceptical tone pervaded the report. ‘Conveniently,’ it was noted, ‘spacemen speak English very well – usually with an American accent.’ One conference attendee reported how ‘spacemen ha[d]

visited him often, once even stayed for [a] meal of ham and eggs.’ Another remembered how he had been on-board a spaceship where he saw various inventions including ‘a closet that clean[ed] clothing with light,’ linking alien technology with new domestic, consumer prod- ucts. A third met an alien chief, ‘a small, beautiful woman’ who ‘engaged him in philosophical discussions.’109 The tone here was somewhat tongue-in-cheek, echoing the 1957 Gore Vidler satiric-comedy play ‘Visit to a Small Planet’ concerning a well-dressed, well-spoken alien, Mr. Kreton, who lands on a Virginia lawn, causing mayhem in the everyday lives of American citizens.110 The flying saucer had become merely a playful nuisance, disrupting but neither disordering nor destroying the pattern of everyday life.

Conclusion

You’d better pray to the Lord when you see those flying saucers It may be the coming of the Judgment Day
It’s a sign there’s no doubt of the trouble that’s about
So I say my friends you’d better start to pray

... If you’ll just stop and think you’d realize just what it means They’re more than atom bombs or falling stars.
(When You See) Those Flying Saucers, 1947.111

In July 1947, the Buchanan Brothers, comprised of the country musicians Chester and Lester Buchananreleased‘(WhenYouSee)ThoseFlyingSaucers’ontheRCAVictorrecordlabel.This continued their propensity for combining current news stories with more traditional country music themes. In August 1946 their song ‘Atomic Power’ had been a modest success. Other songs released by the pair in 1947 included ‘The Silver Meteor,’ ‘There is a Power Greater than Atomic,’ and ‘The Steam That Blows the Whistle (Never Turns the Wheel).’ Fast forward nine years, to July 1956, when Luniverse released Bill Buchanan and Dickie Goodman’s ‘The Flying Saucer’(a.k.a.‘The Flying Saucer Parts 1 and 2’) - a mix of sampled sounds and spoken word arrangements describing a flying saucer landing. The different thematic emphases of the two songs reflect a shift in how the flying saucer was seen within American culture. On the one hand, ‘(When You See) Those Flying Saucers’ preached the moral message of unidentified objects in the night sky, connecting the sacred and the stars, the potential of Judgment Day with technological Armageddon, and the threat of invasion from an uniden- tified other. Conversely,‘The Flying Saucer’demonstrated that the flying saucer could appear as an object of fun and an icon of popular culture, still capable of generating fear, but safely contained within the context of nearly a decade of cultural inversions, hoaxes, explanations, and mutations. The flying saucer, thrusting towards perpetual newness, and discarding its past like the trails of a comet, was received by the public in thoroughly fragmented form. It wasanobjectwovensubstantially,ifnotentirely,‘withcitations,references,[and]echoes.’112 If the narrative fragment is the ‘trope of the modern,’113 then the flying saucer bears witness to this fragmentation. Beginning with a voice-over, imitating Orson Welles’ 1938 War of the Worlds radio broadcast, Buchanan and Goodman’s song solemnly intones, ‘we interrupt this record to bring you a special bulletin. The report of a flying saucer hovering over the city has been confirmed. The flying saucers are real.’ Interspersed with music samples and sci-fi sound effects, the song ends with the US President bidding farewell to the spaceman with the words ‘lay off my blue suede shoes,’ and the spaceman stating ‘see you later, alligator.’114

In this song, the flying saucer is thoroughly domesticated. A decade of pop-cultural activity had transformed the flying saucer from ultimate outsider, to a familiar, if not entirely friendly, part of American society.

Just a few months after the release of ‘The Flying Saucer,’ the appearance of Sputnik I in the night sky on 4 October 1957 marked a succession in the line of extra-terrestrial objects capable of expressing generational anxieties – anxieties made more real by the satellite’s earthly origins. Flying saucers would still receive attention within popular, respectable forms of media, including Life and Time, yet the initial enthusiasm would not be repeated. The shadow of Sputnik should not obscure how the plasticity of the flying saucer as a cultural object saw it able to pose as a manifestation of optimism, of a bright future pointing to Man’s destiny, of fear, of wonder, marvel and excitement, and to function as a form of entertain- ment played out within the pages of newspaper and periodicals, challenging institutional forms of knowledge, playing the part of a monster, and generating invasion worries in a nation still recovering from the Second World War. Flying saucers brought together the symbolic associations of looking up and looking down; of vigilance and day-dreaming; and of grounded-ness and short-sightedness. They were part of an intricate socio-cultural matrix which placed scientific or institutional knowledge, represented by accounts such as those of Dr Donald Menzel, against popular knowledge, represented by accounts such as those of Donald Keyhoe, and personal knowledge, represented by accounts such as those of Kenneth A. Arnold. These provide a diverse and contradictory archive with which to analyse a specific historical moment of post-war USA and process of cultural construction, one experienced at an individual level, positioned within the realms of popular culture but eluding the grasp of government authority. Read as a collection of sensory experiences, noiselessly carving shapes in the sky and challenging everyday expectation, the counter-cultural, yet domesticated, flying saucer remains an important object for historical inquiry regarding not only the history of psychological phenomena, but also the monstrous geography of the immediate post- World War Two period and of the traditional American institutions of home and homeland.

Astronomie - Das Arecibo-Observatorium erfasst Komet 45P / Honda-Mrkos-Pajdusakova

Arecibo Observatory captures revealing images of Comet 45P/Honda-Mrkos-Pajdusakova
-



Delay-Doppler image of Comet 45P/HMP. Vertical resolution is 7.5 m/pixel. The comet's shape is probably two lobes and is seen here to be about 1.3 km in size.

Though not visible to the naked eye or even with binoculars, the green-tailed Comet 45P/Honda-Mrkos-Pajdusakova (HMP) did not escape the gaze of the world-renowned Arecibo Observatory. Scientists from the University of Arizona's Lunar and Planetary Laboratory (LPL) and the Universities Space Research Association (USRA) at Arecibo Observatory have been studying the comet with radar to better understand its solid nucleus and the dusty coma that surrounds it.

"Comets are remnants of the planet forming process and are part of a group of objects made of water ice and rocky material that formed beyond Neptune", noted Dr. Ellen Howell, Scientist at LPL and the leader of the observing campaign at Arecibo. "Studying these objects gives us an idea of how the outer reaches of our Solar System formed and evolved over time."

Studying the comet with radar not only very precisely determines its orbit, allowing scientists to better predict its location in the future, but also gives a glimpse of the typically unseen part, the comet's nucleus, which is usually hidden behind the cloud of gas and dust that makes up the its coma and tail.

"The Arecibo Observatory planetary radar system can pierce through the comet's coma and allows us to study the surface properties, size, shape, rotation, and geology of the comet nucleus", said Dr. Patrick Taylor, USRA Scientist and Group Lead for Planetary Radar at Arecibo. "We gain roughly the same amount of knowledge from a radar observation as a spacecraft flyby of the same object, but at considerably less cost."

In fact, the new radar observations have revealed Comet 45P/HMP to be somewhat larger than previously estimated. The radar images suggest a size of about 1.3 km (0.8 mi) and that it rotates about once every 7.6 hours. "We see complex structures and bright regions on the comet and have been able to investigate the coma with radar", indicated Cassandra Lejoly, graduate student at the University of Arizona.

This comet is only the seventh imaged using radar because comets rarely come close enough to the Earth to get such detailed radar images. In fact, though 45P/HMP has an orbital period of about 5.3 years, it rarely passes close to Earth, as it is doing now. Comet 45P is one of a group of comets called Jupiter family comets (JFCs), whose orbits are controlled by Jupiter's gravity and typically orbit the sun about every 6 years.

Comet 45P/HMP, which is passing by Earth at a speed of about 23 km/s (relative to Earth) and a close approach of about 32 Earth-Moon distances, will be observed widely at different wavelengths to characterize the gas and dust emanating from the nucleus that forms the coma. As comets orbit the sun, the ices sublime from solids to gases and escape the nucleus. The nucleus gradually shrinks and will disappear completely within in less than a million years.

Radar observations at Arecibo of Comet 45P/HMP began on February 9, 2017 and will continue through February 17, 2017.

China to launch first high-throughput communications satellite in April
-
BEIJING, China plans to launch Shijian-13, its first high-throughput communications satellite, in April, the China Academy of Space Technology (CAST) said Friday.

The 4.6-tonne satellite, with a message capacity of more than 20 GB, will be carried into orbit by a Long March-3B carrier rocket, according to the CAST.

An increase in satellite throughput will provide better access to the Internet on planes and high-speed trains, said Wang Min, deputy head of the CAST's Institute of Telecommunication Satellite.

For the first time, a large number of domestic components have been used on a communications satellite with an orbital life of 15 years, Wang said. It is also the first time electric propulsion has been used on a Chinese satellite.

Shijian-13 has been transported to the Xichang Satellite Launch Center in southwest China's Sichuan Province. After completing in-orbit technical tests, it will be designated as Zhongxing-16.

In 2017, China plans to launch six communications satellites, including Shijian-13 and Shijian-18.

Shijian-18 will be put into orbit by a Long March-5 carrier rocket in June, and will test the DFH-5 satellite platform, Wang said.

Astronomie - spooky action in a distance

.

A 600-year-old quantum experiment in the stars


A new experimental Bell test used distant starlight to dictate how entangled photons on Earth were measured. Cathal O'Connell reports.

Physicists have used the light of stars some 600 light-years from Earth to validate a bizarre quantum phenomenon Albert Einstein derided as “spooky action at a distance”.

The work, reported in Physical Review Letters, confirms that the quantum explanation for "spooky action" is valid, and rules out any influence from other sources – at least over the 600 years it took the starlight to reach us. 

It’s the latest in a long series of experiments aiming to prove beyond doubt that our universe is fundamentally weird and not deterministic.

Quantum physics for the terminally confused

Quantum entanglement is the mysterious connection between particleswhere one particle seems to influence the other, no matter how far apart they are. 

Though entanglement has become the basis of quantum technology, such as the quest to build a quantum computer, the idea has had a rough ride to acceptance. 

Einstein and his crew of quantum sceptics, which included American physicist Boris Podolsky and Israeli physicist Nathan Rosen, thought there must be something else going on – so-called hidden variables, as yet beyond our ken, determining the behaviour of quantum objects.

In the 1960s, the Northern Irish physicist John Bell came up with a way to distinguish between the “spooky action” of quantum theory and the influence of hidden variables. 

Say you create two entangled photons shooting off in opposite directions. Now you measure if the light waves are “waving” in an up-down direction or left-right – called polarisation.

On paper, Bell showed that, for entangled particles, the results would be strongly related to one another. A correlation higher than a certain threshold could not be explained by any hidden variable theory. 

If right, this idea would mark the death knell for any of the hidden variable ideas favoured by Einstein. 

Physicists have been testing Bell’s inequality ever since, although any time it seemed proved, detractors have been able to point out loopholes in the experiments where a hidden variable might creep in.

Results might be explained by particles that communicate faster than the speed of light, for instance, or by a bias in the measuring system.

Quantum computing for the qubit curious

Then in 2015, after decades of work, several teams independently managed to close these two major loopholes. But one other, called the “freedom-of-choice” loophole, remained.

In Bell experiments, it matters whether you measure the polarisation in either the up-down direction or the left-right direction. Deciding which way to do it must be made individually for each pair of particles. (And one experiment might involve thousands of these individual runs.)

The freedom-of-choice loophole questions whether some unknown effect might be influencing this choice. To close it, physicists have used a quantum number generator to make the choice and set this far away – 144 kilometres – from the measuring equipment. This ruled out spooky influence in the microseconds it takes light to travel 144 kilometres. 

Now, quantum physicists have looked to the stars to be their random number generator. Johannes Handsteiner from the Austrian Academy of Sciences and colleagues used the light from two stars, with the closest 600 light-years away, to determine how their experiment measured photons.

This means that to affect the experiment, any unknown process would have had to have acted 600 years ago, when the light was emitted – a fair stretch of the imagination, even for the most ardent quantum sceptics. 

The team proposes the method could be paired with even older light, such as quasars billions of years old, or the cosmic microwave background. Such measurements could “progressively push any viable hidden-variable models further back into deep cosmic history”.

Astronomie - Winston Churchills Ansichten über Aliens in einem verlorenen Aufsatz

Winston Churchill's views on aliens revealed in lost essay

A newly unearthed essay by Winston Churchill reveals he was open to the possibility of life on other planets.

In 1939, the year World War Two broke out, Churchill penned a popular science article in which he mused about the likelihood of extra-terrestrial life.

The 11-page typed draft, probably intended for a newspaper, was updated in the 1950s but never published.

In the 1980s, the essay was passed to a US museum, where it sat until its rediscovery last year.

The document was uncovered in the National Churchill Museum in Fulton, Missouri, by the institution's new director Timothy Riley. Mr Riley then passed it to the Israeli astrophysicist and author Mario Livio who describes the contents in the latest issue of Nature journal.

Churchill's interest in science is well-known: he was the first British prime minister to employ a science adviser, Frederick Lindemann, and met regularly with scientists such as Sir Bernard Lovell, a pioneer of radio astronomy.

This documented engagement with the scientific community was partly related to the war effort, but he is credited with funding UK laboratories, telescopes and technology development that spawned post-war discoveries in fields from molecular genetics to X-ray crystallography.

Image captionIn the essay, Churchill outlines the concept of habitable zones - more than 50 years before the discovery of exoplanets

Despite this background, Dr Livio described the discovery of the essay as a "great surprise". 

He told the BBC's Inside Science programme: "[Mr Riley] said, 'I would like you to take a look at something.' He gave me a copy of this essay by Churchill. I saw the title, Are We Alone in the Universe? and I said, 'What? Churchill wrote about something like this?'"

Dr Livio says the wartime leader reasoned like a scientist about the likelihood of life on other planets.

Churchill's thinking mirrors many modern arguments in astrobiology - the study of the potential for life on other planets. In his essay, the former prime minister builds on the Copernican Principle - the idea that human life on Earth shouldn't be unique given the vastness of the Universe. 

Churchill defined life as the ability to "breed and multiply" and noted the vital importance of liquid water, explaining: "all living things of the type we know require [it]."

More than 50 years before the discovery of exoplanets, he considered the likelihood that other stars would host planets, concluding that a large fraction of these distant worlds "will be the right size to keep on their surface water and possibly an atmosphere of some sort". He also surmised that some would be "at the proper distance from their parent sun to maintain a suitable temperature". 

Churchill also outlined what scientists now describe as the "habitable" or "Goldilocks" zone - the narrow region around a star where it is neither too hot nor too cold for life.

Image captionChurchill supported the development of game-changing technologies such as radar

Correctly, the essay predicts great opportunities for exploration of the Solar System. 

"One day, possibly even in the not very distant future, it may be possible to travel to the Moon, or even to Venus and Mars," Churchill wrote.

But the politician concluded that Venus and Earth were the only places in the Solar System capable of hosting life, whereas we now know that icy moons around Jupiter and Saturn are promising targets in the search for extra-terrestrial biology. However, such observations are forgivable given scientific knowledge at the time of writing.

In an apparent reference to the troubling events unfolding in Europe, Churchill wrote: "I for one, am not so immensely impressed by the success we are making of our civilisation here that I am prepared to think we are the only spot in this immense universe which contains living, thinking creatures, or that we are the highest type of mental and physical development which has ever appeared in the vast compass of space and time."

Churchill was a prolific writer: in the 1920s and 30s, he penned popular science essays on topics as diverse as evolution and fusion power. Mr Riley, director of the Churchill Museum, believes the essay on alien life was written at the former prime minister's home in Chartwell in 1939, before World War II broke out. 

It may have been informed by conversations with the wartime leader's friend, Lindemann, who was a physicist, and might have been intended for publication in the News of the World newspaper.

It was also written soon after the 1938 US radio broadcast by Orson Welles dramatising The War of the Worlds by HG Wells. The radio programme sparked a panic when it was mistaken by some listeners for a real news report about the invasion of Earth by Martians. 

Dr Livio told BBC News that there were no firm plans to publish the article because of issues surrounding the copyright. However, he said the Churchill Museum was working to resolve these so that the historically important essay can eventually see the light of day.

Churchill essay on the possibility of alien life discovered in US college

Winston Churchill’s essay Are We Alone in the Universe? was penned the year before he became prime minister, and reveals his keen interest in science

It might never have seen the light of day. Lost and long forgotten, the unpublished essay by Winston Churchill was penned a year before he became Britain’s prime minister. The matter to which he applied his great mind? Not politics, not the battlefield, but the existence of alien life.

The 11-page article was probably intended for the now defunct Sunday newspaper the News of the World, but for reasons unknown the essay remained with his publisher and only recently resurfaced at the US National Churchill Museum at Westminster College in Missouri.

In the essay, Churchill ponders the conditions that make for a habitable world, and on considering the vast number of stars perhaps circled by alien planets, comes to the conclusion that the answer to the essay’s title question, Are We Alone in the Universe?, was surely a resounding “no”.

“The first time I saw it, I thought the combination of Churchill and such a big question had to be a fascinating read, and that proved to be right,” Timothy Riley, the museum’s director, told the Guardian. “It is completely fitting that Churchill would ask such a question. He was keenly interested in science and technological advancement and supported it throughout his long career.” Riley said the museum hopes to make the essay public as soon as it can.

Found by chance in a box at the museum, the newly unearthed article reveals more than Churchill’s ease with scientific thinking. It also shows that as Europe stood on the brink of war, one of the most influential politicians of modern times was hard at work on an article about little green men.

 

Churchill read keenly on science from an early age. While stationed in India with the British Army, the 22-year-old read a primer on physics and Darwin’s On the Origin of Species. In the 1920s and 1930s he wrote scores of magazine and newspaper pieces on popular science, ranging from nuclear fusion to evolution and cells.

He went on to become the first prime minister to hire a science adviser and created government funding for labs, telescopes and technology which led to post-war discoveries and inventions from molecular genetics to x-ray crystallography.

Writing in the journal NatureMario Livio, an astrophysicist and author of an upcoming book, Why? What Makes Us Curious describes how he apparently became the first scientist to read Churchill’s long lost essay on a recent visit to Missouri. “What’s so amazing about the piece is that here is a man, arguably the greatest statesperson of the twentieth century, and in 1939 he not only has the interest, but finds the time, to write an essay about a purely scientific question,” Livio said.

Livio ran a scientist’s eye over Churchill’s essay and was impressed at what he found. “His logic, his train of thought, mirrors exactly what we think today when we think about this question of life elsewhere,” he said.

Churchill starts out by defining what is meant by “life”. Most important, he writes, is the ability to “breed and multiply”. He then moves on to the need for liquid water, an apparent necessity for all living things that still drives the search for alien organisms today.

Modern astronomers talk about stars having a “habitable zone”, a Goldilocks region around them where a planet’s temperature will be neither too hot nor too cold to sustain liquid water. Churchill hit on the same idea, writing that life can only survive “between a few degrees of frost and the boiling point of water.” He was not spot on with every observation. On Earth, some bacteria can survive from -25C to 120C (-13F to 248F).

 

Churchill was a devoted fan of HG Wells and began his essay shortly after the 1938 US radio broadcast of The War of the Worlds, which whipped up Mars fever in the media. He reasoned that Venus and Mars were the only places in the solar system other than Earth that could harbour life, the other planets being too cold, or on Mercury’s sun-facing side, too hot.

At the time Churchill penned the essay, astronomers favoured a theory that had planets form when stars ripped material off one another as they swept past. Because such encounters were bound to be rare, he reasoned that our sun might be alone in hosting planets. But Churchill proved a good sceptic. “I am not sufficiently conceited,” he writes,” to think that my sun is the only one with a family of planets.” His intuition was right. Astronomers have now spotted thousands of planets beyond the solar system.

Step by step, Churchill reaches a view and expresses it a final sentence that mixes despair with optimism. He writes: “I, for one, am not so immensely impressed by the success we are making of our civilisation here that I am prepared to think we are the only spot in this immense universe which contains living, thinking creatures, or that we are the highest type of mental and physical development which has ever appeared in the vast compass of space and time.”

Richard Toye, professor of history at Exeter University, and author of three books on Churchill, said the great wartime leader wrote scores of newspaper and magazine articles before he took office to fund his expensive lifestyle. It was not unknown for Churchill to jot down notes and pay a ghostwriter to flesh a piece out for him.

“It’s always interesting to find something unpublished by Churchill,” Toye said. “This is definitely the kind of thing that would have stimulated his imagination, and equally he would have seen it as a potentially saleable topic for the various Sunday newspapers and American magazines which he liked to publish in.”

“He always spent more money than was coming in and he always had to sell the rights to something or other to keep himself afloat,” Toye added. “Often he managed to do it by the skin of his teeth.”

At a time when a number of today’s politicians shun science, Livio said he found it moving to recall a leader who engaged with it so profoundly. “It does evoke some nostalgia to a time when high ranking politicians could think about such profound scientific questions,” he said.
