Raumfahrt - Zur Marsforschung in die Wüste

.

DLR-Wissenschaftler Volker Maiwald ist Crewmitglied der Mars Desert Research Station Utah

 

Der Mars liegt im amerikanischen Bundesstaat Utah, ganz in der Nähe von Hanksville. So soll es sich zumindest für Volker Maiwald anfühlen, wenn er am 23. Februar 2013 für zwei Wochen in die Mars Desert Research Station einzieht. Normalerweise beschäftigt sich der Wissenschaftler des Deutschen Zentrums für Luft- und Raumfahrt (DLR) am Institut für Raumfahrtsysteme in Bremen mit Machbarkeit, Kosten und Nutzen von Raumfahrtsystemen und -konzepten der Zukunft, berechnet Flugbahnen und plant Habitate für isolierte oder harsche Umgebungen. Als Mitglied der Crew 125 wird er nun selbst erfahren, wie ein Team aus sechs Mitgliedern auf dem Mars leben würde.

"Der Mars ist in Reichweite", wirbt die Mars Society auf der Homepage der Marsstation. Der Zusammenschluss von Mars-Begeisterten betreibt die Forschungsstation in der Wüste von Utah und stellt den Betrieb für die wechselnden Besatzungen sicher. Die neue Heimat auf dem Mars ist denkbar klein: Gerade einmal zehn Meter Durchmesser hat die "Büchse", in der sich die sechs Astronauten aufhalten werden. "Die Zimmer bestehen nur aus einem sehr schmalen Bett, einem kleinen Klapptisch und einem halben Meter Platz davor - alles also sehr spartanisch", sagt Volker Maiwald. Aber auch eine Station auf dem Mars würde den Bewohnern kaum mehr Platz bieten. In dem zweistöckigen Marshabitat ist die obere Etage dem Wohnen, Kochen und Essen vorbehalten, in der unteren Etage sind die Laborarbeitsplätze und die Schleuse für den  Spaziergang auf dem "Mars". Zur Station gehören auch ein Observatorium und ein Gewächshaus.

Forschung im Gewächshaus

Eben dieses Gewächshaus hat es Volker Maiwald besonders angetan. "Für tatsächliche Missionen auf anderen Planeten oder Leben und Arbeiten in abgelegenen Gegenden wie der Antarktis ist ein Gewächshaus sehr wichtig." Der Wissenschaftler will sich deshalb unter anderem ein Bild davon machen, wie effektiv die Ernten im Mars-Greenhouse sind und ob die bisherigen Konzepte des DLR auch der Realität standhalten würden. Zurzeit forscht Volker Maiwald gemeinsam mit Daniel Schubert und Dominik Quantius in der Abteilung Systemanalyse Raumsegment an verschiedenen Möglichkeiten von geschlossenen Lebenserhaltungssystemen, bei denen - isoliert von Einflüssen der Außenwelt - zum Beispiel Pflanzen wachsen und geerntet werden können. Wo könnte in dem künstlichen Mars-Habitat ein so genannter Micro-Harvester des DLR stehen, in dem Salat, Kräuter oder Tomaten möglichst schnell gezüchtet werden können? Wie wird das Gewächshaus der Mars Desert Research Station genutzt? Der Ingenieur für Luft- und Raumfahrttechnik hofft auf praktisches Wissen, das er von seinem Zwei-Wochen-Aufenthalt mitbringen wird. "Wir werden Wissen für zukünftige Marsmissionen sammeln, aber auch für Anwendungen auf der Erde", sagt er.

Ausflüge auf den "Roten Planeten"

Im Team selbst wird Volker Maiwald als stellvertretender Kommandant die Crew unterstützen und sich als Habitat-Ingenieur um die gesamte Technik der Mars-Station kümmern. "Ich bin zum Beispiel für die Überwachung der Energie- und der Wasserversorgung und auch für die Kommunikationswege zur Außenwelt verantwortlich." Täglich wird er ein Protokoll an die "Bodenkontrolle" schicken, um über den aktuellen Status zu berichten. Zum wissenschaftlichen Programm der Crew 125, die die Europäische Raumfahrtorganisation ESA ins Habitat schickt, werden aber auch Ausflüge in einer Art Raumanzug auf das Außengelände gehören, bei denen biologische und geologische Experimente durchgeführt werden. Eine Webkamera im Inneren der Station wird rund um die Uhr mit Fotoaufnahmen dokumentieren, wie die internationalen Crewmitglieder aus Deutschland, Japan, den Niederlanden, Ungarn und Kanada im Team auf dem Roten Planeten leben und arbeiten. Am 9. März 2013 wird der DLR-Wissenschaftler dann wieder vom "Mars" zur Erde zurückkehren und das Habitat in der Wüste verlassen. "Es gibt nicht viele Orte auf der Erde, an denen man so eine Erfahrungen machen kann", ist sich Maiwald sicher.

Raumfahrt - Erfolgreicher erster "Hot-Fire" Antares-Triebwerkstest

.

Orbital Successfully Conducts First Stage "Hot Fire" Test of Antares Space Launch Vehicle

-- Company Completes Final Ground Testing on New Medium-Class Launch Vehicle --

 

-- Next Program Milestone: Test Flight From Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility --

 

(Dulles, VA 22 February 2013) -- Orbital Sciences Corporation (NYSE: ORB), one of the world’s leading space technology companies, today announced it successfully conducted an extended-duration “hot fire” test of the first stage propulsion system of its new Antares™ medium-class rocket. Developed over a four-plus-year period, Antares will be used to launch cargo supply missions to the International Space Station as part of a $1.9 billion contract with NASA.

 

The 29-second hot fire test took place at 6:00 p.m. (EST) on February 22, 2013 at the Mid-Atlantic Regional Spaceport’s (MARS) Pad 0A, which was designed and built over the last several years to accommodate liquid-fuel space launch vehicles. The primary goals of the test were to ensure that the launch complex’s fueling systems and the Antares stage one test article functioned properly in a fully operational environment, that engine ignition and shut down commands operated as designed, and that the dual AJ26 first stage engines and their control systems performed to specifications in the twin-engine configuration. The test included a full propellant loading sequence, launch countdown and engine ignition operation. The pad’s high-volume water deluge system flowed throughout the entire period of the test to protect the pad from damage and for noise suppression.

 

“Our initial assessment of the test data shows that we were successful in achieving each of the primary objectives we had hoped to accomplish going into the test,” said Mr. Mike Pinkston, Orbital’s Antares Program Manager. “We will now turn our attention to the next major milestone for the Antares program, which is the inaugural flight of the rocket. I know that I speak for the entire Antares team when I say we are beyond excited to know that our newest rocket will take to the skies in just a matter of weeks.”

 

With the hot fire test complete, Orbital will purge and clean the engines of residual propellants and return the first stage test unit to the vehicle integration facility for full reconditioning. Shortly after completing pad and fueling systems post-test inspections and performing any necessary reconditioning work, Orbital will roll out the first complete two-stage Antares rocket to prepare it for the test flight, which is expected to take place in approximately six weeks.

 

Orbital is scheduled to conduct two launches under the Commercial Orbital Transportation Services (COTS) Space Act Agreement with NASA in 2013. In addition, the company will launch eight operational cargo resupply missions to the International Space Station (ISS) using Antares vehicles from late 2013 through 2016 under the Commercial Resupply Services (CRS) contract with NASA. The COTS and CRS flights will launch from NASA’s Wallops Flight Facility in eastern Virginia, which is ideally suited for ISS missions, and can also accommodate launches to other orbits. In addition, Orbital is currently evaluating its options for development of a west coast launch site that would enable the Antares rocket to address an even wider range of customer missions.

 

The Antares medium-class launch system will provide a significant increase in the payload launch capability that Orbital can provide to NASA, the U.S. Air Force and other customers. The Antares rocket will be able to launch up to 14,000 lbs. into low-Earth orbit, as well as lighter-weight payloads into higher-energy orbits.  Orbital’s newest launcher is currently on-ramped to both the NASA Launch Services-2 and the U.S. Air Force’s Orbital/Suborbital-3 contracts, enabling the two largest U.S. government space launch customers to order Antares for “right-size and right-price” launch services for medium-class spacecraft.

Aerojets AJ26 Engines Ignite Successful Antares(TM) Stage Test Hot Fire

SACRAMENTO, Calif., Feb. 22, 2013 (GLOBE NEWSWIRE) -- Aerojet, a GenCorp (NYSE:GY) company, announced that its dual AJ26 main engine system successfully powered today's Antares™ Stage 1 Hot Fire test conducted by Orbital Sciences Corporation (NYSE:ORB) at the Mid-Atlantic Regional Spaceport located at NASA's Wallops Flight Facility on the eastern shore of Virginia.

The 29-second test enabled engineers to validate flight configuration checkout of the Antares main engine system and first stage booster. During this "strap down" test, the AJ26 engines produced approximately 680,000 lbs of sea-level thrust.

"Today's successful stage test positions us one step closer to supporting Orbital's historic flight test," said Aerojet Vice President of Space & Launch Systems, Julie Van Kleeck. "We're proud to deliver for the Antares team and we're looking forward to continuing the countdown toward the inaugural mission."

The AJ26 is a commercial derivative of the NK-33 engine that was first developed for the Russian N-1 rocket. The NK-33, oxidizer-rich, staged-combustion LO2/Kerosene engine is among the highest thrust-to-weight ratio of any Earth-launched rocket engine.

"Aerojet purchased the NK-33 engines from JSC Kuznetsov in the mid-1990s and has been developing design modifications to ensure that the AJ26 is suitable for U.S. commercial launch vehicles," said Aerojet Executive Director of Space & Launch Systems, Pete Cova. "As teammates, JSC Kuznetsov brings tremendous technical support to our efforts and we are looking forward to supporting Orbital in its Cargo Resupply Contract with NASA."

Raumfahrt-History - Apollo-Astronaut James B.Irwin im CENAP-Interview 1985

.

Einer der Renomierbeweise aller UFOlogen sind die so genannten UFO-Sichtungen durch irdische Astronauten. Nicht eines der Raumfahrtprojekte der USA, oder der ehemaligen Sowietunion  soll, will man diesen Leuten glauben schenken, von den Auswirkungen außerirdischer Manöver verschont geblieben sein. Seit die japanische UFOlogengruppe „CBA“ die, ihrer Meinung nach „sensationellen“ Fotos der amerikanischen Apollo 11 Mission auf den internationalen UFO- Markt geworfen hat, scheinen manche die Sache als bewiesen anzusehen.. Nur was sie nicht sagten und viele auch heute noch nicht wissen ist, dass es sich bei den so genannten „Apollo- Schneemännern“ nur um Auschnittvergrößerungen handelte, da die in den NASA- Originalfotos deutlich zu sehen war, um was es sich in Wirklichkeit handelt. Die Lösung ist recht einfach, wenn man diese Originalbilder sieht! Es sind einfache Linsenspiegelungen des Kameraobjektivs.
        
         Wie dem auch sei, auch jetzt noch geistern Fotos und Aussagen in der Weltpresse umher die von aktuellen oder ehemaligen Astro- und Kosmonauten gemacht worden sein sollen. Wie so oft in der „UFO-Forschung“, muss man sich hier ebenfalls auf Aussagen aus zweiter oder gar dritter Hand verlassen. Deshalb war es für das CENAP-Team ein großer Glücksfall, dass zwei CENAP- Mitglieder die Gelegenheit hatten, mit einem der Apollo- Astronauten zu reden.
 
         Am 29.03.1985 fand in Schwaigern (Zwischen Heilbronn und Karlruhe gelegen) eine Veranstaltung statt, bei der auch der ehemalige US-Astronaut Col. James B. Irwin als Redner anwesend war um einen Vortrag über die erfolgreiche Mission von Apollo 15 und seine Erlebnisse während seines Aufenthaltes auf dem Mond zu halten.
 
         Natürlich wollten sich dies Oskar Böß und Roland Gehardt vom CENAP-Heilbronn diese Chance mit einem leibhaftigen Mondbesucher zu reden nicht entgehen lassen. Doch da der Saal mit ca. 1400 Besuchern mehr als voll war, war die Möglichkeit mit Irwin ins Gespräch zu kommen mehr als gering. Doch, wie das Leben so spielt, stand Irwin auf einmal neben ihnen und sie hatten die Gelegenheit ihm einige Fragen zu stellen, die der Astronaut auch gerne beantwortete.
 
         Irwin, der unter anderem auch darum bekannt wurde, weil er auf dem Mond einen Bibeltext zitierte und auf der Suche nach der biblischen Arche fast ums Leben gekommen wäre, schrieb unter anderem auch das Buch „UFOs- Fact or Fantasy“ erschienen bei High Flight Foundation, CO 80901, USA,
 
CENAP: Mr. Irwin, wir sind eine Gruppe die sich mit UFOs und deren Erforschung auseinander setzt. Aus diesem Grund möchten wir einige Fragen an Sie stellen.
 
IRWIN: Gut, fangen Sie an.
 
CENAP: Mr. Irwin, Sie wissen, dass jeden Tag UFOs gemeldet werden. Was halten Sie von diesem Phänomen?
 
Irwin: Soviel ich weiß, wurden schon Millionen Sichtungen gemacht, von denen die wenigsten untersucht wurden. Von denen die untersucht wurden, konnte man ca. 95% natürlich erklären. Den Rest halte ich persönlich für Phantasieprodukte.
 
CENAP: Es gibt viele Berichte, wo von  Sichtungen durch Astronauten die Rede ist. So wird z.B. behauptet, dass Gordon Cooper und Scott Carpenter UFOs sahen, bzw. fotografierten.
 
IRWIN: Sehen Sie, im Weltall gibt es viele Dinge, die man anfangs für etwas ungewöhnliches halten kann. Da gibt es Staubkörner, Schrott, Abfälle, Eisteilchen usw.
 
         Mir ist jedoch kein Astronaut bekannt, der jemals sagte, dass er ein außerirdisches Raumschiff gesehen hätte.
 
CENAP: Mr. Irwin, haben Sie irgendwann mal etwas gesehen, das man als UFO bezeichnen könnte?
 
IRWIN: Nein!
 
CENAP: Vielen Dank Mr. Irwin, dass Sie sich die Zeit genommen haben unsere Fragen zu beantworten!
 
IRWIN: Bitte sehr, gern geschehen.
 
         Dieses Gespräch zeigt deutlich, dass auch im Bezug auf die so gerne herangezogenen Astronautensichtungen das letzte Wort noch nicht gesprochen wurde, und dass es auch auf diesem Sektor noch eine Menge aufzuklären gilt.

Raumfahrt - ISRO will Polar Satellite Launch Vehicle's (PSLV) im Oktober zum Mars starten

.

BANGALORE: The country's first mission to Mars will be launched in October, a source at the Indian Space Research Organisation (Isro) here confirmed to TOI. It'll be the culmination of 10 missions planned this year.
It'll be launched using a Polar Satellite Launch Vehicle's (PSLV) XLor extended model rocket from Sriharikota. On reaching the red planet, it'll be inserted into its electrical orbit.
The nine-month voyage will study the origin of Mars and gain more information about the planet, the source said. "Methane sensors will be used to predict the possibility of life on the planet," the official added.
Isro chairman, K Radhakrishnan, in a recent interview to TOI, said 58 space missions have been planned during the 12th Plan. These include comprising 33 satellite missions and 25 launch vehicle missions (17 PSLVs, 6 GSLVs and 2 GSLV MK III).
"This plan necessitates 25 launches from Sriharikota over five years for injecting 23 Indian satellites and a few foreign satellites onboard PSLV. The 10 heavier Indian geostationary satellites will be launched from an overseas location," he said.
Isro officials confirmed the agency is set to launch the Indo-French satellite SARAL which will study ocean currents and sea surface heights on Feb 25 from Sriharikota. The launch was initially scheduled for December 12, 2012 but was delayed as the agency found some problems during the satellite's space simulation tests at Bangalore in October.

Astronomie - Plasma-Regen auf der Sonne

.

Talk about real-world special effects: NASA has just released stunning video of a “coronal rain,”  a solar phenomenon in which hot plasma appears to rain down in great arches onto the surface of the sun.
What you see in the video is actually three types of eruptive events: A solar flare — a sudden eruption that causes a flash of electromagnetic radiation and light; a coronal mass ejection (CME), which is when the sun sends some of its matter shooting out into space; and finally, the dazzling coronal rain that occurs when the super hot plasma that rose  into the sun’s atmosphere begins to cool and trace strong magnetic fields back to the surface of the sun.
Solar flares, CMEs and even coronal rains are not so unusual, said Alex Young, a solar astrophysicist at NASA Goddard Space Flight Center.  But it wasn’t until 2010, when the Solar Dynamic Observatory was launched into orbit, that it was possible to see the sun in this kind of detail.
To get the images for this video, which were collected in July 2012, the SDO sent back one 4,096 pixels-by-4,096 pixels frame every 12 seconds.
Each second of this video corresponds to six minutes of real-time, so what has been condensed into a four-minute video actually unfolded over the course of several hours.
And here’s one more detail to blow your mind: Check out this screen grab from the video, which gives you a sense of just how massive our sun and its phenomena actually are.

Astronomie - Neue Dimensionen: Nebel sind noch erstaunlicher in 3D

.

.....

As unbelievable as it may seem, space photos just got a bit more amazing.
Normally, the celestial sights we gaze at -- such as ribbons of colorful gas and dust, wound around monstrous, dark caverns or splashed in front of star-studded skies -- are flat. Two dimensional.
Now, Finnish astrophotographer J-P Metsavainio has rendered some spacescapes in three dimensions, using his own photographs as a starting point. "Objects in the images are not like paintings on the canvas, but really three-dimensional objects floating in the three-dimensional space," he said in an e-mail.
First, Metsavainio collects information about how far away an object is, and carefully studies the stars and structures in and around it. Then, he creates a volumetric model of his subject -- usually a nebula, although he's rendered at least one globular star cluster. Finally, he animates the 3-D rendering, providing viewers with a tantalizing taste of what it might be like to fly a starship through these enormous astronomical ornaments.
"How accurate the final model is, depends how much I have known and guessed right," Metsavainio said. Many of his renderings carry the statement: "NOTE: This is a personal vision about shapes and volumes, based on some scientific data and an artistic impression."

Raumfahrt - Ist NASA vom Mars Besessen geworden ?

.

The landing of the Curiosity rover was a huge hit for nasa in the summer of 2012. Now the space agency is letting its winnings ride with another bet on Mars. Last December, NASA announced plans to send a similar rover to the Red Planet in 2020—its seventh planned or active Mars mission—citing the low risk and cost savings of a mission reboot.
NASA's fixation on Mars (or on avoiding risks) comes at the expense of the rest of the solar system. Outer planets Uranus and Neptune have scarcely been explored. The same goes for Jupiter's moon Europa, which planetary scientists believe to be a promising habitat for extraterrestrial life.
Recently a team of researchers proposed a novel mission concept: a floating spacecraft that would explore the hydrocarbon seas of Saturn's moon Titan. But NASA opted instead for a Mars lander called InSight—which, like the 2020 rover, is a low-risk mission based on proved hardware.

Raumfahrt - Space-Shuttle Atlantis Ausstellungshalle auf KSC

.

KSC officials: Atlantis will "wow" the crowd when exhibit opens

.

KENNEDY SPACE CENTER — Mark your calendars — June 29 is the grand opening date for the $100 million Space Shuttle Atlantis exhibit at the Kennedy Space Center Visitor Complex — then prepare to be awestruck by the magnificent flying machine.
“The very first time, it really is a ‘Wow!’ And that’s exactly what we wanted,” said Tim Macy, director of project development and construction with Delaware North Parks & Resorts, the company that operates the visitor complex under a NASA contract. “It’s like, ‘Wow, I didn’t know it was that big.’ You know, ‘How does it fit in this building?’”
With a wingspan of 78 feet, the orbiter Atlantis is 122 feet long and stands almost 57 feet tall. In its brand new retirement hangar at the entrance to the visitor complex, Atlantis is raised 30 feet off the ground and inclined 43 degrees, showcasing it on an angle as if it were flying in space.
Sixty-feet long, its clamshell-like payload bay doors will be open, and its 50-foot Canadian-built robotic arm extended. What it won’t look like is a gleaming new machine.
“When we first got it in the building and lifted it, it looked like it was kind of beat up a little bit. But it’s a used piece of space hardware, and it’s real,” Macy said.
After all, the orbiter flew 33 missions between October 1985 and July 2011, travelling 126 million miles during 307 days in the hostile space environment. It was pinged by micrometeorites and orbital debris during 12 missions to the International Space Station, seven flights to Russia’s space station Mir, a trip to the Hubble Space Telescope and five clandestine Department of Defense missions.
Wearing hardhats and bright yellow vests, visitor complex officials gathered today to announce the grand opening date and the official name of the exhibit.
“We went through literally hundreds of name combinations for this,” said Bill Moore, Delaware North’s chief operating officer at the KSC visitor complex. “There were three words that kept coming up.”
Space. Shuttle. Atlantis.
“It’s very simple. It honors the soul of what it is,” Moore said. “And we’ll simply call the exhibit Space Shuttle Atlantis.”
A new logo for the exhibit was unveiled, too. Against a background as black as space, fiery orange letters simply spell Space Shuttle Atlantis. The “A” in Atlantis is a shuttle orbiter silhouette.
“It represents what the space shuttle program is all about,” Moore said. “We tried in some way to capture the fiery entry of the shuttle’s return to Earth, the flame and smoke when it leaves Earth, the tiles behind us are symbolized – the heat protection that it had. The iconic silhouette of an orbiter on the pad — we used that to outline the ‘A’ in Atlantis.”
The NASA “meatball” insignia also is featured. Moore said it is “one of the most well-known logos around the world.” Paying tribute to the launch site are the words Kennedy Space Center.
“It is both patriotic and monumental,” Moore said.
So in 128 days, the Space Shuttle Atlantis exhibit will open to the public and include a large-as-life replica of an external tank-solid rocket booster stack. “It’s going to be pretty spectacular,” Macy said.
Work crews now are laboring almost around the clock – 20 hours a day. In mid-May, a skin-tight plastic sheath protecting the orbiter from construction debris will be peeled away from the spaceship. The payload bay doors will be opened, the robot arm extended – painstakingly careful work that will take about five weeks.
Replicas of the Hubble Space Telescope and the International Space Station will be raised. Complementary interactive and immersive exhibits will be set up to chronicle 30 years of shuttle fleet operations, 135 missions that were triumphant and twice tragic.
“The present is wrapped, and I’ll tell you, it’s a heck of a gift,” said Rick Abramson, president of Delaware North Parks & Resorts and former COO of the KSC visitor complex.
“People here will have an opportunity to get closer to this real live space artifact than ever before – than any other place,” he said. “With this connection comes a greater understanding and appreciation of the 30-year history of the space shuttle.”
Not to mention hundreds and thousands of people who worked on the program, and those that worked right up until the final days.
“If there is one thing that — I don’t know why I was taken aback by it – it’s the professionalism, the care that they put into it, the love that they have for the shuttle itself,” Macy said. “It’s really impressive — very, very impressive. “

United Launch Alliance Successfully Launches Third X-37B
Orbital Test Vehicle for the Air Force
First Spacecraft to Launch on an Atlas, Return to Earth and Launch Again
Cape Canaveral Air Force Station, Fla., (Dec. 11, 2012) – A United Launch Alliance (ULA) Atlas V rocket successfully launched the third Orbital Test Vehicle (OTV-3) for the Air Force’s Rapid Capabilities Office (AFRCO) at 1:03 p.m. EST today from Space Launch Complex-41. The OTV, also known as the X-37B, supports space experimentation, risk reduction, and concept of operations development for long duration and reusable space vehicle technologies. The first two OTV missions also were successfully launched by ULA respectively on April 22, 2010 and March 5, 2011.
"The ULA team is proud to have played a critical role in successfully launching these three important Orbital Test Vehicle missions for the Air Force RCO,” said Jim Sponnick, ULA vice president, Mission Operations. “This is a unique spacecraft since it is the first to launch on an Atlas V, return to Earth landing at Vandenberg Air Force Base in California, and then fly again on this mission.”
This launch completes the most aggressive campaign in the history of the Evolved Expendable Launch Vehicle (EELV) program with 10 missions launched during 2012, including eight launches from Cape Canaveral Air Force Station in Florida and two from Vandenberg Air Force Station in California.
This mission was launched aboard an Atlas V EELV 501 configuration vehicle, which includes a 5-meter diameter payload fairing. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by a single Pratt & Whitney Rocketdyne (PWR) RL10A-4 engine.
“I sincerely congratulate our OTV customer on today’s successful launch as well as our integrated team of mission partners that successfully accomplished ten critical one-at-a-time launches in 2012,” said Sponnick. 
The EELV program was established by the United States Air Force to provide assured access to space for Department of Defense and other government payloads. The commercially developed EELV Program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems. 
ULA's next launch is the Atlas V TDRS-K mission for NASA scheduled Jan. 29, 2013 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla.
ULA program management, engineering, test, and mission support functions are headquartered in Denver, Colo. Manufacturing, assembly and integration operations are located at Decatur, Ala., and Harlingen, Texas. Launch operations are located at Cape Canaveral AFS, Fla., and Vandenberg AFB, Calif.

12/11/2012 - CAPE CANAVERAL, Fla. (AFNS) -- In the next installment to improve space capability and further develop an affordable, reusable space vehicle, the Air Force conducted its third X-37B Orbital Test Vehicle launch here on December 11, officials said.
The launch comes on the heels of the successful flight of OTV-2, which made an autonomous landing at Vandenberg Air Force Base, Calif., June 11 after a record 469 days in space. 
"We couldn't be more pleased with the strides we've made in this program and the success of the X-37B vehicle on the first two flights," said Mr. Richard McKinney, Deputy Under Secretary of the Air Force for Space. "However, it is important to keep in mind that this is an experimental vehicle and a third mission is still relatively young for a test program. This is the first re-flight of a vehicle so that is certainly a key objective for us. We have only just begun what is a very systematic checkout of the system."
Lieutenant Colonel Tom McIntyre, X-37B program manager for the Air Force Rapid Capabilities Office, explained the third X-37 flight will not only help the Air Force better evaluate and understand the vehicle's performance characteristics, but this first re-flight is an important step in the program. OTV-1 launched in April 2010 and spent 224 days in orbit before going through the refurbishment process prior to being prepped for this mission, he said. 
"This mission will incorporate the lessons learned during the refurbishment process on OTV-1," said Lieutenant Colonel McIntyre. "As the X-37B program is examining the affordability and reusability of space vehicles, validation through testing is vital to the process. We are excited to see how this vehicle performs on a second flight."
"The X-37B OTV is designed for an on-orbit duration of approximately 9 months," said Lieutenant Colonel McIntyre. "As with previous missions, actual duration will depend on the execution of test objectives, on-orbit vehicle performance, and conditions at the landing site."
The X-37B Orbital Test Vehicle is led by the Air Force Rapid Capabilities Office, and is designed to demonstrate reusable spacecraft technologies for America's future in space and operating experiments which can be returned to, and examined, on Earth. Technologies being tested in the program include advanced guidance, navigation and control, thermal protection systems, avionics, high temperature structures and seals, conformal reusable insulation, lightweight electromechanical flight systems, and autonomous orbital flight, reentry and landing. 
Officials anticipate multiple missions will be required to satisfy the test program objectives, but the exact number of missions has not been determined.

US Military's Robot Space Plane Settles Into Mystery Mission
The U.S. Air Force's mysterious X-37B space plane is quietly chalking up mileage in space more than two months after its latest launch into orbit.
The robotic X-37B space plane soared into orbit atop an Atlas 5 rocket from Florida's Cape Canaveral Air Force Station on Dec. 11. The mini-shuttle's mission is known as Orbital Test Vehicle-3 (OTV-3), since it is the third classified mission under the Air Force's X-37B program.
How long OTV-3 will remain in Earth orbit is unknown. The hush-hush space plane mission is officially on Air Force space tracking books as USA-240.
