Yes you know it must be a requirement for Astronauts and Cosmonauts to take a PCR test

Not if they cover the distance from the Space Station to the re-entry vehicle with a space walk.
Thank you! That made me laugh out loud!
When were the boosters ?
😉
I'm sure they engage their boosters before firing their Retro Rockets.
