Space Junk Forces ISS Crew to Takes Shelter in Soyuz

[/caption]

The six crewmembers on board the International Space Station were told to take shelter in the two Russian Soyuz spacecraft early Tuesday because Space Command predicted a piece of space junk could make a close approach to the station. Radar tracking indicated the debris would make its close pass at 8:08 a.m. EDT (12:08 UTC), coming within about 243 meters (800 feet) of the station and well within the “pizza box” -shaped area around the ISS, but when no impact was detected the crew was told they could reenter the station and resume normal operations.

NASA’s Chief Scientist for Orbital Debris Nicholas L. Johnson told Universe Today during a previous “conjuction” of space debris and the ISS that on average, close approaches to ISS occur about three times a month. An approach of debris is considered “close” only when it enters an imaginary “pizza box” shaped region around the station, measuring 0.75 kilometers above and below the station and 25 kilometers on each side( 2,460 feet above and below and 15.6 by 15.6 miles).

Johnson said that small pieces of debris have already collided with ISS on many occasions, but these debris to date have not affected the safety of the crew or the operation of the mission. “The dedicated debris shields on ISS can withstand particles as large as 1 cm in diameter,” he said.

The piece of space junk was detected too late for the station to perform an evasive maneuver, so the crew was told to “shelter in place” on the two Soyuz spacecrafts. The crew on board is commander Andrey Borisenko, Alexander Samokutyaev and Ronald Garan, who took shelter aboard the Soyuz TMA-21 spacecraft docked to the Poisk module, and Sergei Volkov, Michael Fossum and Furukawa who went on to the Soyuz TMA-02M spacecraft docked to the Rassvet module.

Double Spaceship Sighting Alert — and Last Chance to See Endeavour in Orbit

[/caption]

UPDATE: And we have a sighting! Beth Katz from Pennsylvania in the US sent us this image,an 8 second exposure of the ISS and Endeavour taken early this morning. “We observed them seeming even further apart and then closer as they moved away from us,” Beth said via email.

Space shuttle Endeavour will undock from the ISS just before midnight EDT on Sunday night/Monday morning at 11:55 pm EDT (3:55 UTC) and depending where you live, you might have an opportunity to see the two spaceships flying in tandem. People in Europe might have the chance to see the two spaceships right after they separate in the early morning hours, and people in the US/Canada/Mexico might be able to see the two flying close to each other. This is an incredible sight, and will be the last opportunity to see Endeavour in orbit, as she will be retired after she lands and completes the STS-134 mission. The station and shuttle will appear in the night or early morning sky as a closely-spaced pair of bright lights. The ISS is bigger, so will appear as the brighter object trailing the smaller Discovery as they move across the sky.

On Monday night/Tuesday morning, there will be another chance to see the two ships, although they will be widely separated.

To find out if you’ll be able to see the two spaceships in your area, there are a few different sites to check out:


NASA has a Skywatch page where you can find your specific city to look for satellite sighting info.

Spaceweather.com, has a Satellite Tracker Tool. Just put in your zip code (good for the US and Canada) to find out what satellites will be flying over your house.

Heaven’s Above also has a city search, but also you can input your exact latitude and longitude for exact sighting information, helpful if you live out in the country.

Seeing the two spacecraft flying closely in tandem is a very unique and thrilling sight. Good luck! If you manage to capture any images, send them to Nancy.

Fuel Droplet Burning in Space is Psychedelic, Man

[/caption]

Dude! This awesome image looks like a psychedelic 1970’s flashback. But is is actually a droplet of fuel burning in space, on board the International Space Station. NASA explains that because of the absence of gravity, fuels burning in space behave very differently than they do on Earth. The Flame Extinguishing Experiment on board the ISS is examining the combustion of such liquid fuel droplets, and in this image, a 3-millimeter diameter droplet of heptane fuel burns in microgravity, producing soot. When a bright, uniform backlight is placed behind the droplet and flame and recorded by a video camera, the soot appears as a dark cloud. Image processing techniques can then quantify the soot concentration at each point in the image.

NASA explains:

This colorized gray-scale image is a composite of the individual video frames of the backlit fuel droplet. The bright yellow structure in the middle is the path of the droplet, which becomes smaller as it burns. Initial soot structures (in green) tend to form near the liquid fuel. These come together into larger and larger particles which ultimately spiral out of the flame zone in long, twisting streamers.

Far out!

Soyuz Crew Lands Safely

[/caption]

The Expedition 27 crew of Commander Dmitry Kondratyev and Flight Engineers Paolo Nespoli and Cady Coleman landed upright in a remote area southeast of the town of Dzhezkazgan, Kazakhstan, on Tuesday, May 24, 2011, after more than five months onboard the International Space Station. After undocking fromt he station, Nespoli took the first still images and video of a space shuttle docked to the station. In order to get the best view for the photo-op, the ISS had to rotate 130 degrees.

See a (shaky) video of the landing, below.

Russian recovery teams helped the crew exit the Soyuz and adjust to gravity. Kondratyev will return to the Gagarin Cosmonaut Training Center in Star City, outside of Moscow, while NASA’s Coleman and Nespoli of the European Space Agency will fly directly to Houston.

They launched on a Soyuz back on Dec. 15, 2010, and spent 159 days in space. They worked on more than 150 microgravity experiments in human research; biology and biotechnology; physical and materials sciences; technology development; and Earth and space sciences.

AMS Now Attached to the Space Station, Ready to Observe the Invisible Universe

The long-awaited Alpha Magnetic Spectrometer, a particle physics detector that could unlock mysteries about dark matter and other cosmic radiation, has now been installed outside the International Space Station. It is the largest and most complex scientific instrument yet on board the orbiting laboratory, and will examine ten thousand cosmic-ray hits every minute, looking for nature’s best-kept particle secrets, searching for clues into the fundamental nature of matter.

“Thank you very much for the great ride and safe delivery of AMS to the station,” said Dr. Samuel Ting, speaking via radio to the crew on orbit who installed the AMS. Ting is the AMS Principal Investigator who has worked on the project for close to 20 years. “Your support and fantastic work have taken us one step closer to realizing the science potential of AMS. With your help, for the next 20 years, AMS on the station will provide us a better understanding of the origin of the universe.”

“Thank you, Sam,” Endeavour commander Mark Kelly radioed back, “I was just looking out the window of the orbiter and AMS looks absolutely fantastic on the truss. I know you guys are really excited and you’re probably getting data and looking at it already.”

By collecting and measuring vast numbers of cosmic rays and their energies, particle physicists hope to understand more about how and where they are born, since a long-standing mystery is where cosmic rays originate. They could be created in the magnetic fields of exploded stars, or perhaps in the hearts of active galaxies, or maybe in places as yet unseen by astronomers.

The AMS is actually AMS-02 – a prototype of the instrument, AMS-01, was launched on board the space shuttle in 1998, and showed great potential. But Ting and his collaborators from around the world knew that to make a significant contribution to particle science, they needed a detector that could be in space for a long period of time.

AMS-02 will operate on the ISS until at least 2020, and hopefully longer, depending on the life of the space station.

The AMS will also search for antimatter within the cosmic rays, and attempt to determine whether the antimatter is formed from collisions between particles of dark matter, the mysterious substance that astronomers believe may make up about 22% of the Universe.

There is also the remote chance that AMS-02 will detect a particle of anti-helium, left over from the Big Bang itself.

“The most exciting objective of AMS is to probe the unknown; to search for phenomena which exist in nature that we have not yet imagined nor had the tools to discover,” said Ting.

For more information about the AMS, NASA has a detailed article.

Endeavour Docks at Space Station

Space shuttle Endeavour docked for the final time at the International Space Station carrying six astronauts and the long-anticipated Alpha Magnetic Spectrometer, a physics experiment that will hunt for dark matter and antimatter. The docking occured at 1014 GMT, and the hatches between the two vehicles opened at 1138 GMT (7:38 am Eastern time), about an hour earlier than scheduled.

Above, watch as space shuttle Endeavour performs the Rendezvous Pitch Maneuver, or “backflip” so that the ISS crew can take high resolution pictures of the shuttle’s heat shield. Commander Mark Kelly rotated Endeavour to rotate 360 degrees backward.

[/caption]
The combined crews total 12 now on the ISS, but only until May 23, when space station crew members Dmitry Kondratyev, Cady Coleman and Paolo Nespoli undock in a Soyuz and return home to Earth. Unlike most shuttle missions to the ISS, the two crews are working in staggered shifts instead of being on the same timeline. This is because of the two-week launch delay for Endeavour making the mission, unfortunately, causing the mission to overlap with the departure of the station crew members. The three leaving the ISS need to adjust their sleep cycle to synch up with the landing day timeline.

The shuttle will remain at the station until May 30, with landing scheduled currently for June 1.

The STS-134 mission includes four spacewalks, in part to install the Alpha Magnetic Spectrometer-2, a two-billion-dollar, 15,000 pound (7,000 kilogram) particle detector that will hopefully operate for a decade and provide new details about the origins of the Universe.

The mission is commanded by astronaut Mark Kelly, the husband of US Congresswoman Gabrielle Giffords who is recovering after being shot in the head in January. Giffords reportedly will undergo intensive cranioplasty brain surgery in Houston this morning (May 18), just three days after attending the launch.
