How astronauts celebrate Christmas in space

Just in time for Christmas, a SpaceX cargo vehicle arrived at the International Space Station bearing holiday treats and science experiments.

The orbiting laboratory is hosting seven crew members throughout the holiday season.

The international crew includes Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov; NASA astronauts Raja Chari, Dr. Thomas Marshburn, Kayla Barron and Mark Vande Hei; and European Space Agency astronaut Matthias Maurer.

"Even though we'll be up here this year, we have our space family," Barron said in a special holiday video shared by NASA. "I think we're going to create some of our own traditions, and we'll be able to talk to our family on the ground. ... I think I'll make sure that I give my family a call let them know how much I'm thinking about them, how much I love them and how much I can't wait to see them when I get home."

Maurer joked that the crew will be able to celebrate Christmas together 16 times as the space station orbits the Earth.
