NASA: Watch astronaut Christina Koch's dog's joy when she returns from space
Now at Newsround we definitely DON'T have a favourite astronaut but if we did, it might be Christina Koch!
The record-breaking spacewoman has just come home after spending almost a year on the International Space Station.
We reckon she was very pleased to see her family again and she probably missed her dog loads.
But wait till you see how much her adorable dog missed her! Awww!
Astronauts Christina Koch and Jessica Meir have made the first all-female spacewalk
Female astronauts hope to be an 'inspiration to do something great'
