Like Kelly, Vande Hei underwent medical testing during his long stay to further NASA's quest to get astronauts back to the moon and on to Mars. He said daily meditation helped him cope during the mission, twice as long as his first station stint four years earlier.
"I've had an indoor job 24-7 for almost a year so I am looking forward to being outside no matter what kind of weather," Vande Hei said in a recent series of NASA videos. As for food, he's looking forward to making a cup of coffee for himself and wife Julie, and digging into guacamole and chips.
Remaining on board: Three Russians who arrived two weeks ago and three Americans and one German, who have been aboard since November. Their replacements are due in three weeks via SpaceX. Next week, SpaceX will fly three rich businessmen and their ex-astronaut escort to the station for a weeklong visit arranged by the private Axiom Space.
Elon Musk's SpaceX began transporting NASA astronauts to the station in 2020, nine years after the shuttle program ended. During that gap, Russia offered the lone taxi service, with NASA shelling out tens of millions of dollars per Soyuz seat. Vande Hei's ride was part of a barter exchange with Houston-based Axiom.
