International Space Station crew members may be out of this world, but they're still busy with earthly social media.

Space Station Command Scott Kelly shared this video of "a single orbit #MerryChristmas around the world from @space_station." The around-the-world in 39 seconds video is well-worth the time.

Early, British astronaut Tim Peake tweeted an apology to a woman who received his accidental call from orbit on Christmas Even. Seems Peake dials a wrong number. "I'd like to apologise to the lady I just called by mistake saying 'Hello, is this planet Earth?' - not a prank call...just a wrong number!"
