They reunite with their best animal friend, of course.
Christina Koch, an American astronaut from Houston, Texas, came back last week from a record-breaking space mission. Koch broke the record for the longest continual space flight for a woman during her ISS residency.
When Koch opens the door, LBD sprints out to greet her before Koch even has a chance to get inside. As soon as Koch walks in, the elated canine is heard crying loudly and whining joyously.
The Michigan-born astronaut also revealed she was able to fulfill her cravings for tortilla chips and salsa when she came home to a kitchen stocked with her favorite foods. But perhaps one of Koch's most most important contributions was that she herself was the subject of study while in space.
"I felt like a two-week-old who was actually working hard to hold up my own head", she said, describing her first few days back in gravity.
According to NASA, Koch's space mission concentrated mainly on biology, technology development and the quest for evidence of dark matter.
Christina Koch returned from the International Space Station earlier this month.
The mission gave researchers the opportunity to observe the effects of long-duration spaceflight on a woman.
"And then there was this", Koch wrote on Twitter next to a photo of her barefoot, toes in the sand, arms spread wide, thoroughly enjoying the beach.
Nasa astronauts Christina Koch and Jessica Meir completed the job with wrenches, screwdrivers and power-grip tools, it marked the first time in a half-century of spacewalking that men weren't part of the action.
