Today, astronauts on the International Space Station will celebrate the day in many of the same ways that people on Earth celebrate the holiday — relaxing, talking to friends and family, and sharing a special meal. But they do it all while weightlessly floating inside a laboratory that's whizzing around the Earth at 17,500 mph (28,000 kilometers/hour).
Astronauts at the space station even have gifts from home to open this morning. The gifts were sent to space earlier this month inside a Japanese cargo supply ship. Because the spacecraft goes around the Earth every 92 minutes, its occupants will see about 15 sunrises throughout the day. That's 15 Christmas mornings in less than 24 hours!
Instead of waking up and getting straight to work, like they did on Thanksgiving, the astronauts will enjoy the day off for Christmas. NASA spokesman Dan Huot told Space.com that the astronauts usually get Sundays off anyway, so this year they'll have Monday (Dec. 26) off as well. [Holidays in Space: An Astronaut Photo Album]
As is tradition, the astronauts sent Christmas wishes down from space this week in preparation for the worldwide holiday. On Tuesday (Dec. 20), NASA shared a video in which three of the six crewmembers aboard the station talked about what the holiday means to them — and what's on the dinner menu, of course.
French astronaut Thomas Pesquet rocks a classic Santa hat in the video. In that weightless environment, though, his hat takes on the pointy shape of one you'd find on an elf or a lawn gnome. At least it didn't float away from his head. Kudos to Pesquet for sporting his Christmas spirit!
Pesquet talked about his big family back home in France, where his grandmother would usually cook huge meals for him and his 25 cousins. "I won't be able to be there of course but I'll think of them. I'll try to give them a call and catch up as much as I can and make the most of this opportunity to look at the Earth and reflect about what Christmas means to us, to individuals, to the world in general, and I think we'll have a good time on board the ISS and share a Christmas meal together," Pesquet said.

Their meal will consist of many of the same foods Americans eat during the holidays — turkey, green beans, potatoes, cornbread stuffing and fruit salad. But instead of using plates, they’ll be eating out of cans and pouches. The astronauts even get to enjoy some gingerbread cookies, chocolate cake and hot cocoa for dessert.

Besides the traditional American holiday fare, Pesquet has some "French delicacies" to share with his crewmates: chicken supreme with morels and ox tongue, for example. From the subtle looks on his face, American astronaut and ISS commander Shane Kimbrough seemed a bit skeptical about trying the foreign foods Pesquet discusses in the video.
NASA astronaut Peggy Whitson was also in the video. "I think being on board the ISS gives us a slightly different perspective of Christmas," she said. "Obviously friends and family are important to all of us. But besides funny hats there is another very important aspect of being on [the] ISS, and that’s seeing the planet as a whole, and it actually reinforces, I think, that the fact that we should live as one people and strive for peace."
