WASHINGTON -- NASA Television will provide live coverage May 12-14 as three crew members aboard the International Space Station end five months in orbit and return to Earth for a scheduled landing May 13.

Expedition 35 Commander Chris Hadfield of the Canadian Space Agency, Tom Marshburn of NASA and Roman Romanenko of the Russian Federal Space Agency (Roscosmos) will undock their Soyuz TMA-07M spacecraft from the station at 7:08 p.m. EDT May 13, heading for a landing on the steppe of Kazakhstan southeast of Dzhezkazgan at 10:31 p.m. (8:31 a.m. Kazakh time, May 14). They will have spent 146 days in space since their Dec. 19 launch from Kazakhstan.

Undocking will mark the official start of Expedition 36 under the command of Pavel Vinogradov of Roscosmos. Vinogradov and his crewmates, Chris Cassidy of NASA and Russian cosmonaut Alexander Misurkin, will tend to the station as a three-person crew for two weeks until the arrival of three new crew members, NASA astronaut Karen Nyberg, Russian cosmonaut Fyodor Yurchikhin and Luca Parmitano of the European Space Agency.

NASA TV coverage will begin Sunday, May 12, with the change of command ceremony between Hadfield and Vinogradov. Coverage will continue May 13 and 14 with Expedition 35 landing and post-landing activities.

NASA TV's full coverage schedule is as follows (all times EDT):

Sunday, May 12: 3:40 p.m. -- Expedition 35/36 change of command ceremony

Monday, May 13: 3:30 p.m. -- Farewells and hatch closure (hatch closure scheduled at 3:50 p.m.) 6:45 p.m. -- Undocking (undocking scheduled at 7:08 p.m.) 9:15 p.m. -- Deorbit burn and landing (deorbit burn scheduled at 9:37 p.m., landing scheduled at 10:31 p.m.) Midnight --Video file of hatch closure, undocking and landing activities

Tuesday, May 14: Noon -- Video file of post-landing activities and interviews

A NASA astronaut sees his work aboard the International Space Station as a means of bringing humanity a little closer to setting foot on Mars.

During a 25-minute webcast Tuesday (May 7), members of the U.S. Senate Committee on Commerce, Science and Transportations Subcommittee on Science and Space asked NASA's Tom Marshburn to delve into the science, downtime and other parts of life on the space station.

"I believe I'm living and working in the first Mars vehicle," Marshburn said during the event. "Everything that we've learned here is going to be used, and needs to be used, in the next generation of [space-traveling] vehicles." [The Boldest Mars Missions of All Time]

For example, understanding how to recycle resources efficiently in Earth orbit could lead to life-support systems that help send astronauts to Mars or farther out into the solar system, Marshburn said.

Life in space also changes the perspective of people living on the International Space Station, Marshburn added.

"I wish every head of state around the world could come see our Earth from the cupola," Marshburn said of the Earth-observing glass structure on the bottom of the station. "It's a 360-degree view ... I've found that I've fallen in love with the Earth again. It's almost impossible to pull your eyes away from it."

Although looking out the window is one of Marshburn's favorite pastimes on the station, crewmembers are usually too busy to stare back at Earth during their work hours, he said.

Marshburn told members of the subcommittee that his days in orbit are filled with science. The astronauts are responsible for conducting more than 100 experiments on the orbiting laboratory.

"What surprised me was that how busy and vibrant life and the work here is on the space station," Marshburn said. "The space station is a hard place to go to sleep. There's a lot going on up here. There's so much going on up here that it's hard to stop."

But it isn't all work and no play for the astronauts.

Space Station Is Big Step Toward Mars, Astronaut Says

Summary: The International Space Station's laptops are moving from Windows to Linux, and R2, the first Linux-powered humanoid robot in space, is now under-going in-flight testing.

Unlike my recent spoof story about a Linux-powered Iron Man suitthat you could build at home, this story isn't science fiction. NASA really has decided to drop Windows from the laptops on the International Space Station (ISS) in favor of Linux, and the first humanoid robot in space, R2, really is powered by Linux.

Keith Chuala, a United Space Alliancecontractor, manager of the Space Operations Computing (SpOC) for NASA, and leader of the ISS's Laptops and Network Integration Teams, recently explained that NASA had decided to move to Linuxfor the ISS's PCs."We migrated key functions from Windows to Linux because we needed an operating system that was stable and reliable one that would give us in-house control. So if we needed to patch, adjust, or adapt, we could."

Specifically, the ISS astronauts will be using computers running Debian 6. Earlier, some of the on-board computers had been using Scientific Linux, a Red Hat Enterprise Linux (RHEL) clone. While not the newest version of Debian, Debian 7 has just been released, Debian is nothing if not well-tested and reliable.

While Linux has been used on the ISS ever since its launch (PDF link) and for NASA ground operations almost since the day Linus Torvalds created it, it hasn't seen that much use on PCs in space. "Things really clicked," said Chuala in an interview, "after we came to understand how Linux views the world, the interconnectedness of how one thing affects another. You need that worldview. I have quite a bit of Linux experience, but to see others who were really getting it, that was exciting."

In addition to appearing on in-flight laptops, Linux is also running Robonaut (R2), the first humanoid robot in space. Currently on the station and experimental mode, R2 is meant to carry out tasks too dangerous or tedious for astronauts.

To help astronauts and IT specialists get up to speed, NASA is relying on The Linux Foundation for training. As Chuala explained, "NASA is as heterogeneous as it gets".

"They had a heavy Debian Linux deployment, but also various versions of RHEL/Centos. Because our training is flexible to a variety of distributions, we're able to address all those different environments in a single training session. No other training organization can provide that."

And, I might add, no other operating system is as flexible as Linux. From supercomputersto robots to desktops, NASA is finding that Linux is the answer.

I dont know too much about the upcoming moving Elysium, but it looks pretty cool. Here is the trailer. The first interesting thing I saw was the rotating space station.

Why are you weightless in space? I have already answered this question in great detail. The short answer is that you dont really feel gravity anyway since it acts on all parts of your body equally and on the space station. Both the space station and all parts of your body have the same acceleration which means there is no interaction forces between them. What you actually feel is not the gravitational force, but rather the force that other objects push on you. On the surface of the Earth, you are mostly at rest. This means that the ground has to push up on you to balance the gravitational force and you feel weight.

Ok, Im not going to spend more time talking about weightlessness. If you arent happy with my short answer, read my other post. For now, lets say that you have a person in a space station. The space station could be in orbit around the Earth or in deep space where there are no strong gravitational forces. Either way, the person will be weightless.

How do you make a person feel weight? One way is to accelerate the person so that there is a force from the ground of the space station that is similar to Earth. Here is a force diagram of a person on the surface of the Earth and a person in the space station with fake gravity.

The person on the ground has the two forces that are equal in magnitude (thus no acceleration). I am calling FN the normal force. This is the force the person feels and calls weight. Now, we want the astronaut person to have this same FN force. Since there is no gravitational force, this one force would make the person accelerate in that same direction.

That is our fake gravity force make the person accelerate. There are two ways this person could accelerate in that direction. The person could increase in speed in that direction, this would be an acceleration. However, this would also change the velocity. For a station in orbit, this wouldnt work but it would be fine for a spaceship traveling to another star and accelerating. No, for the space station we need to do something else. The answer is to make the acceleration perpendicular to the velocity of the person so that the person moves in a circle.

When an object moves in a circle, the velocity vector is always changing and the direction of this change in velocity is towards the center of the circle. Acceleration is the rate of change of the velocity vector. Its really that simple. Here is how this would work.

And this is your basic spinning space station. You have seen this in countless space movies because it is an idea that would actually work. How do you change the acceleration of the object moving in a circle? There are two things to change, the radius of the circle and the speed that you move in a circle. The magnitude of this acceleration is:
