Put the astronaut in a chair in an airtight space, then release the astronaut from the chair, and the astronaut will flash into the airtight space. And sit back in the chair and flash back.
This is because the astronaut is placed inside a fuel tank. When released from the chair, they collide with the fuel tank and they are pushed out. Use a cargo bay instead of a fuel tank.
