Planet Erde - Mysteriöser Riesen Riss öffnet sich in den Bighorn-Bergen in Wyoming

.

With no warning a 2,250 feet long and 150 feet wide crack formed in the foothills of the Bighorn Mountains in Wyoming. This crack in the earth was not formed by an earthquake and there was no seismic activity associated with the crack, leaving many wondering what formed this massive break in the earth’s surface in less than 2 weeks.
The 100 feet deep crack is in an area where there is no seismic activity, no oil and gas drilling, or commercial development, it left many wondering what had caused this crack and whether it was likely to reoccur nearby. The crack is located on state-owned land surrounded by private ranches used to herd cattle.  The crack poses no danger to people or property based on its location in a remote area of Wyoming surrounded by state and private land.After inspection from local geologists, it was concluded that the crack had formed as a result of a wet spring saturating the topsoil in the area. This saturated topsoil became unstable and with the aid of small springs on either side, the whole block slid out. Average annual rainfall in Ten Sleep, Wyoming, nearby the crack is 13.11 inches.Often time’s underground springs will find pathways of least resistance. This could have caused a change in orientation of the springs to align with an inactive legacy fault or a weaker sedimentary unit. This deformation is a result of slope failure by gravity alone, although it was undoubtedly hastened by saturated soil conditions.
.
This form of slope failure is called a slump, where a coherent unit of sediment moves a short distance down a slope due to gravitational forces. The common causes of slump are soil wetting/drying, and freeze and thaw cycles. Slumps will have shear planes which are slightly concave upward and outward. A slump is different from other mass transport deposits such as turbidites, debris flows, or landslides in that the sediment remains relatively in tact and moves as one cohesive unit a short (less than a mile typically) downslope.
“Wyoming is a geologic wonderland, and this is just an example of that wonderland,” said Wyoming state geologist Tom Drean

Raumfahrt - Diese Astronauten der NASA haben bisher längste Langzeit-Aufenthalte im All

.

Imagine being trapped in a small space where you can't easily go outside. You're far away from friends, family and everything familiar to you. You're working hard for very long hours. Worse, your every move is being monitored by a trained team of experts who will jump in if you do something wrong.
An episode of Big Brother? No, it's the typical life of an astronaut. The view is glorious and they do get to explore the limits of the human body and technology, but it's very hard work -- especially when you do it for months. Scott Kelly recently surpassed the record for the most time an American has spent in space. Although Russian cosmonauts dominate the record books for longest spaceflights (Valeri Polyakov holds the world's longest spaceflight record, having spent 438 days on board the Russian Mir space station in 1994-1995), read more about the U.S. citizens who have spent the most time in orbit on a single spaceflight.
.
SCOTT KELLY (342 DAYS, SCHEDULED)
Scott Kelly knows much about the rigors of spaceflight, having already spent 159 days on the International Space Station before his most recent launch on March 27. Kelly will spend nearly a year aboard station along with Russia's Mikhail Kornienko, studying how the body reacts to long-term stays in space. Kelly has a twin, former astronaut Mark Kelly; the two are doing genetic studies as well to see what changes take place.
Unlike many previous long-duration astronauts, Kelly has been able to share his thoughts on Twitter -- a service that only became available on the ISS in 2009. Recent tweets include: "I voted from @space_station last weekend. Your turn, #USA!" and "Day 220. A cloud over #Qatar reminds me of the pillow I miss at sleep. #GoodNight from @space_station!"
.
MICHAEL LOPEZ-ALEGRIA (215 DAYS)
Lopez-Alegria did three shuttle flights before spending a lengthy tour of duty aboard the station during Expedition 13/14 between September 2006 and April 2007. His crew had a break from the usual few faces when the STS-116 shuttle crew visited for eight days. Otherwise, they kept busy with five spacewalks, two cargo Progress-M vehicle arrivals, and hundreds of hours of science work.
"I wasn’t smart enough to invent a cure for cancer, I couldn’t play the piano like a concert pianist, I couldn’t do a lot of things, or anything really, really well, but I could do sort of a handful of things reasonably well," Lopez-Alegria said in a 2006 pre-flight interview with NASA. "And when I looked at what the astronaut profile was -- at that time they’d just started hiring shuttle astronauts -- and so it seemed like they were looking for people with a broad skill base, and I kind of thought that I might be able to fit into that."
-
MICHAEL BARRATT (199 DAYS)
Barratt launched to the station in March 2009 and remained there until October that year. His flight (Expedition 19/20) saw a suite of interesting changes, such as the first Japanese cargo vehicle arrival (HTV) and the first six-member crew on the ISS. Besides which, two space shuttle crews came by for brief visits and lots of additional science. Barratt even did two spacewalks -- in a Russian spacesuit.
"I probably have a story common to a lot of the people in the astronaut corps in that we go through career crisis because we have so many broad interests," Barratt said in a 2010 pre-flight interview with NASA. "A lot of us are interested in science and technology, but we’re also interested in flying and engineering and practical things, and I don’t think I knew what I wanted to be when I grew up until I was in my mid-thirties or so."
-
TERRY VIRTS (199 DAYS)
Virts had a very long spaceflight recently, between December 2014 and June 2015, but his stay was overshadowed by the arrival of the one-year crew. His crew saw the final European cargo vehicle leave the station, and Virts himself did three spacewalks to get the station ready for future human spacecraft.
"I grew up in Maryland where my parents worked at the Goddard Spaceflight Center, so that wasn’t directly involved in the Apollo or the human space flight," Virts said in a 2010 pre-flight interview with NASA. "But there were rockets and talk of space and so, at a really young age, I was interested in space and being an astronaut."
-
DAN BURSCH (196 DAYS)
Bursch had three shuttle flights under his belt before launching to the ISS for an early mission, Expedition 4, for a long stay between 2001 and 2002. A lot of his time was spent making sure that the station was operational, and he also put in two spacewalks using the Russian Orlan suit.
"With my experience in the Navy I think of it as kind of like a naval deployment, where we were gone anywhere from four to eight months at a time," Bursch said in a 2001 pre-flight interview with NASA. "But it's also different in that we're not, it's as if we're doing a whole naval deployment, but we're only doing it with the two other people in our bunkroom or in our stateroom, which is different in itself, and on occasion getting visitors from the Earth. So mentally, I think ... the preparation for it is different."
-
CARL WALZ (196 DAYS)
Walz, a crewmate of Bursch, also had three shuttle flights complete before Expedition 4 in 2001. He did two spacewalks, one each in a NASA suit and a Russian Orlan suit, to get a docking compartment ready and to prepare the space station for a structural truss.
"Well, I see myself somewhere between a test engineer and a maintenance man, I guess," Walz said in a 2001 pre-flight interview with NASA. "We'll spend a lot of time testing out systems making sure that they're working right; we'll be using those systems during the flight, and then the other thing that I failed to mention previously is that we're going to be maintaining systems on board the station."
-
SUNITA WILLIAMS (195 DAYS)
Williams is very used to long-term spaceflight, having spent two tours of duties aboard the ISS. She did a 195-day stay as a part of Expedition 14/15 in 2006-7, also establishing a world record of the time for females in terms of time spent outside for spacewalks (more than 29 hours). She then broke the record again during her second flight in 2012 as a part of Expedition 32/33, and holds the current female spacewalk record of 50 hours and 40 minutes. Her two stays in space -- at 322 days -- put her second in terms of endurance for all female astronauts, and sixth in America.
"I think it’s going to be pretty busy. But, it’s going to be a lot of fun, and I’m absolutely lucky to be in this place at this time," Williams said in a 2006 pre-flight interview with NASA.

Raumfahrt - US Marine Trident-Raketen-Test vor der Küste von Kalifornien

.

The mysterious light spotted over Las Vegas and other parts of the West came from a Trident missile test-fired by the Navy off the coast of California, according to the San Diego Union-Tribune.
The test flight was conducted from the Kentucky, an Ohio-class ballistic missile submarine, in the Pacific Test Range, a Navy spokesman said.
These tests are frequent, not routinely announced and used to ensure the reliability of the system, according to Cmdr. Ryan Perry with the Navy's Third Fleet.
The light was originally believed to be a part of the Taurid meteor shower, but an astrophysicist at UC San Diego said the meteors would have been coming from the east and wouldn't appear until about midnight.
Military activity forces L.A. airport to detour night flights
Nighttime flights into and out of Los Angeles International Airport will avoid passing over the Pacific Ocean just to the west of the airport for the coming week because the U.S. military has activated airspace there, Reuters reported Saturday.
The Federal Aviation Administration and the military did not disclose the nature of the activities taking place near the second-busiest U.S. airport.
Airplanes normally fly over the ocean when arriving and departing the coastal Los Angeles International Airport during the night to avoid disturbing nearby residents, airport officials said in a statement.
But the FAA has indicated that military airspace over that patch of ocean was activated beginning on Friday night and continuing through Thursday night, airport officials said.
As a result, the airport will need to deviate from normal flight patterns during the next six nights, the statement said.

Raumfahrt - Vorbereitung für Spaces Falcon 9 mit 11 Orbcomm Ships Satelliten

.

The first shipment of Orbcomm’s 11-satellite payload for the Falcon 9 rocket’s first flight since a June launch failure has arrived at Cape Canaveral, and the rest of the spacecraft will reach the Florida spaceport in the coming days, Orbcomm officials said Thursday.
The liftoff is expected in December aboard SpaceX’s return-to-flight mission, and the maiden launch of an uprated version of the Falcon 9 booster designed to lift heavier payloads into space.
“We are now planning around a December launch roughly four to five weeks from today,” said Marc Eisenberg, CEO of Orbcomm, in a quarterly earnings call with investment analysts Thursday. “While there’s still some work to do, mostly from the SpaceX side, December is achievable as long as their preparations continue to go well.”
The first six spacecraft due to fly on the launch have arrived at SpaceX’s payload processing facility at Cape Canaveral, with another five due to depart their manufacturing facility near Denver in a few days, Eisenberg said.
The multi-satellite adapter ring, made by Moog, that will dispense the 11 Orbcomm second-generation, or OG2, spacecraft on the launch is also being prepared for liftoff at Cape Canaveral.
Components of the Falcon 9 booster itself are still awaiting shipment from SpaceX’s Central Texas test facility, where they are finishing up qualification testing, to Cape Canaveral.
Upgrades set to to fly first on the Orbcomm mission include “full-thrust” Merlin engines rated for higher thrust levels, bigger upper stage propellant tanks, and densified kerosene fuel. The design changes raise the Falcon 9’s lift capacity by about 30 percent.
With the Falcon 9 grounded since its June 28 launch failure, which SpaceX blames on a structurally deficient strut inside the rocket’s upper stage oxidizer tank, the Orbcomm mission will be both a return-to-flight launch and a critical debut of the company’s latest rocket iteration.
But Eisenberg is confident going into the launch.

“SpaceX and their team have conducted a comprehensive investigation over the last few months to ensure the readiness of the Falcon 9’s return-to-flight,” Eisenberg said. “Considering the huge focus SpaceX has placed on this launch, and the fact that return-to-flight missions generally have more favorable success rates than those following normal missions, we have full confidence in SpaceX and believe this is our best opportunity to launch.”
SpaceX and Orbcomm announced in October the 11-satellite mission, which is heading for low Earth orbit approximately 400 miles in altitude, will be first in line when the Falcon 9 launch queue resumes.
The decision pushed the launch of SES 9, a large telecommunications satellite heading for geostationary transfer orbit stretching more than 22,000 miles above Earth, until at least late December.
The low-altitude orbit targeted on the Orbcomm flight requires a single burn of the Falcon 9’s upper stage Merlin 1D engine, not two firings as needed on geostationary launches like SES 9’s mission.
“Looking at it from Orbcomm’s point of view, we have an opportunity to get launched and kick off new OG2 services that customers have been planning on for quite some time,” Eisenberg said, adding that the mission enables Orbcomm’s AIS vessel tracking service to go from periodic to near-realtime coverage and keeps the spacecraft out of cold storage at Sierra Nevada Corp., the OG2 satellite manufacturer.
“From SpaceX’s perspective, we are an ideal candidate for the first launch of the newly-updated Falcon 9,” Eisenberg said. “Even with 11 satellites, the mass to orbit is nearly 50 percent less than other Falcon 9 missions providing substantial performance margins.”
Officials said the Falcon 9’s upper stage engine will conduct a re-ignition experiment after releasing the 11 Orbcomm payloads about 14 minutes after liftoff, verifying the relight system works before flying satellites that require the capability.
SpaceX has successfully launched several payloads on two-burn missions using the previous Falcon 9 configuration.
Orbcomm, a New Jersey-based company specializing in asset and maritime tracking via satellite, launched six identical satellites on a Falcon 9 flight in July 2014. The 11 satellites set to go in December complete the company’s second-generation constellation.
“From here forward, the satellites will be tested to verify proper operation after transit, fueled, then attached to the Moog dispenser, which once launched is used to dispense the satellites into orbit,” Eisenberg said. “The final satellite operation is to encapsulate the satellite stack into the Falcon 9 fairing.”
Eisenberg said he expects to announce a specific launch date “in a couple of weeks,” but a December launch would be late at night.
“If we launch in December as expected, break out the coffee,” Eisenberg said. “Looks like a late evening event, great for spectators.”
