Christmas on space station

Christmas in orbit might not look exactly like the holidays on Earth, but the astronauts living on the International Space Station this holiday season try to make the orbiting science laboratory as homey as possible.

The six members of the station's Expedition 34 crew, three of whom just arrived last week, are spending Christmas and New Years Day aboard the spacecraft, but that doesn't mean they don't get to celebrate. Hundreds of miles above the Earth's surface, the spaceflyers eat, exchange gifts, and try to be merry during Christmas and when welcoming in the New Year.

The space station crew are off duty for both Christmas Eve and Christmas. That means that they don't need to work on any of the 110 experiments aboard the station, and they can take as much time for meals as they want, NASA spokeswoman Nicole Cloutier-Lamasters told SPACE.com.

The space station residents have a few different decorating options available to them. An earlier expedition left the crewmembers a Christmas tree and stockings made from nomex, a flame resistant fiber that's safe to stow onboard. [Holidays in Space: Astronaut Photo Album]

The week before Christmas was an eventful one for the orbital crew as well. Canadian Space Agency astronaut Chris Hadfield, NASA astronaut Tom Marshburn, and Russian cosmonaut Roman Romanenko arrived on Friday (Dec. 21), joining Kevin Ford of NASA, and cosmonauts Oleg Novitskiy and Evgeny Tarelkin to fill out the $100 billion science laboratory to its usual 6-person capacity.

The spaceflyers also have presents. The Progress 48 cargo freighter a robotic Russian supply ship that launched in early August of this year carried more than just basic supplies to the ISS. The Progress also brought holiday presents for the spaceflyers who'd be spending Yuletide in space.

As well as a traditional meal complete with turkey and candied yams, the crewmembers also get the chance to video conference with their families. This is a particular treat because video chatting is usually possible only once a week, and involves a lot of planning for mission control and the spaceflyers.

Despite NASA's best efforts to make the holidays in space as warm as they are on Earth, that doesn't mean astronauts won't get homesick.
