Colonel Mike Fincke has spent one of the longest times in space - 381 days.
And he's preparing to head back there as a test pilot on NASA's first crewed Starliner mission later this year. The first in almost a decade for the U.S.
If successful, he'll stay at the International Space Station for six months.
Fincke joins Ryan on the show to talk about what being in space is like, seeing the Southern Cross for the first time, his best moments and scariest memories (like seeing his oxygen gauge deplete in seconds whilst doing a space walk), how being in space is similar to being in lockdown, and what food they eat.
Listen to the full interview above.
