Velcroman1 writes "The space shuttle Discovery has docked with the International Space Station for the final time at 2:15 p.m. EST, where it will make a last delivery to the orbiting space lab — before parking ultimately at a museum. With Discovery's presence, the ISS becomes a truly 'international' space station. This is the first time spacecraft from the United States, Russia, Europe and Japan have all docked simultaneously, NASA said. The station also hosts the Leonardo Multipurpose Module built by the Italian Space Agency and recently gained Dextre, the Canadian Space Agency's robotic handyman."

Phoghat writes "Overcoming a down-to-the-last-second problem, space shuttle Discovery made history yesterday, launching on its final mission to orbit. The most-traveled orbiter is carrying a crew of six astronauts and one human-like Robonaut, along with a new permanent storeroom and supplies for the International Space Station." The launch itself went as planned; a few pieces of foam insulation broke free of the external fuel tank on the way up, but it's not expected to be a safety concern, and they're planning an inspection to make sure. NASA has videos of yesterday's launch and a Discovery retrospective, and the Atlantic has a great collection of pictures involving the shuttle. Mike Coats, pilot of Discovery's first mission in 1984, spoke in an interview about his connection to the orbiter. Discovery comes back to Earth on March 7th.

astroengine writes "So we have a space station, now what? We've heard some rather outlandish ideas, but this is one concept a research group in NASA is taking seriously. By retrofitting the ISS with rockets, Nautilus-X will act as an interplanetary space station of sorts, including room for 6 astronauts, an artificial gravity ring, inflatable habitats and docking for exploration spaceships. When can we take a luxury cruise to Mars? 2020 by the project's estimate. It all sounds very 2001, but the projected costs of retrofitting the space station seem a little on the low side."

eldavojohn writes "Apple has been a couple weeks now sans their iconic fearless leader and the shareholders are getting restless without a succession plan. Essentially the Institutional Shareholder Services (ISS) is saying that there hasn't been enough disclosure in why exactly Steve is absent and they'd like an annual succession plan delivered to shareholders. Apple is recommending that on February 23 at its annual company meeting, its shareholders vote against the proposal for a succession plan. Apple may have a plan for life after Steve Jobs but if they do they are not sharing it with anyone — not even their financiers!"

The Bad Astronomer writes "The exceptionally talented astrophotographer Thierry Legault captured a picture extraordinary even for him: the space station passing in front of the Sun while the Sun was being partially eclipsed by the Moon! He traveled all the way from France to the Sultanate of Oman to take this amazing shot. I have more information about the picture itself on the Bad Astronomy blog, but you should go to Thierry's website to see more amazing pictures he's taken over the years. They're simply jaw-dropping."

jnaujok writes "This morning the Falcon 9 rocket carrying the Dragon capsule lifted off from Cape Canaveral at 10:43 Eastern time, after an earlier launch had been scrubbed because of a bad telemetry feed. A little over 9 minutes later, the Dragon capsule separated from the second stage into its intended orbit. Part of the COTS (Commercial access To Space) program, this is the first test of the Dragon capsule by SpaceX to prove it can be used to ferry supplies to the ISS. The Dragon capsule will make two or three orbits before returning to Earth about four hours after launch."

Phoghat writes "Who knew it could take almost seven minutes to get a tour of the teeny-tiny crew quarters on board the International Space Station? But Expedition 26 Commander Scott Kelly provides an engaging peek inside his personal living space, and an inside look at life aboard the ISS."

Normally I avoid slide show type articles, but this one is actually pretty interesting. It starts "This NASA lab contains a recreation of the computer systems found onboard the International Space Station. It is the place where the final bug testing takes place before software is uploaded to the station and where software engineers recreate bugs that occur onboard the station in an attempt to help fix them."

An anonymous reader writes "Here's a chat with a NASA astronaut about how they fix system outages on board the International Space Station, what kind of computing tech they use on board, and how he would like to see the iPad used on the ISS." He talks about using 5 year old laptops because they had been tested to handle the stresses of space travel, as well as the importance of being able to read emails and send pictures to family while aboard a space station for months at a time.

jamie passes along a report about research from MIT's Man-Vehicle Laboratory into using "superhero-style" skinsuits to combat the effects of extended stays in microgravity on bone density in astronauts. (Abstract.) Quoting: "Astronauts lose 1 to 2 percent of their bone mass for each month they spend in space. As far back as the Gemini missions, conditioning exercise regimes have been used to slow the rate of bone loss, but a 2001-2004 NASA-sponsored study showed that crew members aboard the International Space Station were still losing up to 2.7 percent of their interior bone material and 1.7 percent of outer hipbone material for each month they spent in space. ... With stirrups that loop around the feet, the elastic gravity skinsuit is purposely cut too short for the astronaut so that it stretches when put on — pulling the wearer's shoulders towards the feet. In normal gravity conditions on Earth, a human's legs bear more weight than the torso. Because the suit's legs stretch more than the torso section, the wearer's legs are subjected to a greater force — replicating gravity effects on Earth." See? Seven of Nine's outfit was inspired by science after all.

Ponca City writes "JR Minkel writes on Space.com that as NASA celebrates the 10th anniversary of astronauts living on the space station — and with construction essentially complete — the question remains: will the International Space Station ever really pay off scientifically? The space agency contends that the weightless environment provided by the station offers a unique way of unmasking processes of cell growth and chemistry that are hidden on Earth, but some critics don't see a zero gravity laboratory as filling a crucial scientific need. Gregory Petsko, a biochemist at Brandeis University, says the only basic science justification he has ever heard for the station is that protein molecules form superior crystals in the microgravity of space than they do on Earth and a best-case scenario, in terms of return on investment, would be if a space-grown crystal were used to design a blockbuster pharmaceutical drug that worked by precisely targeting one of those proteins. Naturally NASA sees things differently. 'I think those who are naysayers haven't given us a chance — haven't given us enough time to show what we can do. We're just now turning the path to be able to go full force on our science. In the past we had to fit it in around assembly, we didn't have the facilities available, and the crew was always busy.'"

FTL writes "Engineers from the US, Russia, Japan, Canada and Europe have come together to publish an International Docking Standard for spaceships. Currently the space station has three different types of incompatible docking ports, and the Chinese are developing their own. Standardizing on one type would permit interoperability and facilitate emergency rescues."

FleaPlus writes "The BBC reports that the space agencies of Europe, Russia, and the US are in (very) preliminary discussions about a potential collaborative mission where astronauts would assemble a small spacecraft at the ISS, then fly it around the Moon and back. This is somewhat similar to previously-proposed commercial missions, with many elements adapted from spacecraft systems already in existence. This would also be a testbed for eventual asteroid and Mars missions, which would likely require modules to be launched on multiple rockets and assembled in space."

crimeandpunishment writes "If all goes according to plan, the only space sibling team will be hooking up in orbit. And not only are Scott and Mark Kelly brothers, they're identical twins. Scott took off Friday on a Russian Soyuz rocket to begin a five and a half month mission as the next commander of the International Space Station. Mark is the next commander of the space shuttle Endeavour, scheduled to lift off in February and hook up with the space station March 1st."

simonbp writes "The US House of Representatives has just passed the Senate version of the FY2011 NASA Authorization Act. This bill is a compromise between Obama's proposed budget and earlier House bills. It cancels Ares I in favor of commercially-operated crew transportation to ISS, adds technology development funds, and keeps a version of Orion and a new heavy-lift 'Space Launch System' to both be operational by 2016. The timing of this bill was crucial to keeping key NASA personnel and contractors from being laid off."

An anonymous reader writes "Some specific bacteria colonies from Beer (the place, not the beverage) left for several days outside the ISS actually survived extreme temperatures, UV and other radiations, lack of water and all the like. They were later brought back to Earth for examination: such resistant bacteria may be the base of life support systems or bio-mining on colonies off Earth, and of course for terraforming, eventually. No clue in the article about how dangerous those bacteria might have become after the exposure or when they'll start eating their examiners."

An anonymous reader writes "The STS-133 crew will deliver robot Robonaut 2 (R2) to the International Space Station. Cocooned inside an aluminum frame and foam blocks cut out to its shape, R2 is heading to the station inside the Permanent Multipurpose Module in space shuttle Discovery's payload bay. R2, with its humanlike hands and arms and stereo vision, is expected to perform some of the repetitive or more mundane functions inside the orbiting laboratory to free astronauts for more complicated tasks and experiments."

Soulskill writes "Brian Wilcox, a JPL roboticist, spoke at a NASA workshop about the possibility of detaching one of the International Space Station's modules and using it as the primary living space for astronauts on a trip to an asteroid. 'The node could be connected to two space exploration vehicles and have add-on inflatable modules. ... The space station is slated to operate through at least 2020, which roughly coincides with the earliest likely launch date for human exploration of an asteroid. In April President Barack Obama set a 2025 goal for a manned mission to an asteroid.'"

GWMAW writes "NASA Astronauts will conduct a spacewalk on Thursday to repair part of the cooling system of the International Space Station. The cooling system is essential for maintaining the temperature inside the station. There are two 'loops' in the system, one that uses water and draws heat from the inside of the station, and one uses ammonia and dumps the heat into space. Ammonia is used because it freezes at a much lower temperature than water. On Saturday the pump that controls the flow of ammonia through the system shut down."

eldavojohn writes "On Saturday at 8pm GMT, the crew of the International Space Station awoke to alarm bells as one of two ammonia pumps shut down due to a spike in power. Their backup cooling (Loop B) is functioning as designed and NASA released an official statement: 'The crew is in no danger, but will need to work additional troubleshooting on Sunday to keep the station in a stable configuration, including the installation of a jumper cable to maintain proper cooling to the Zarya module in the Russian segment.'"
