Anyone know how fit you have to be to become an astronaut?

If you can pass the physical requirements for being a CATOBAR-launched Navy fighter pilot, you're fit enough to be an astronaut.

It doesn't matter if your brain's not fit enough

No gravity in space means even a dyel can bench 2 plates in space.

The MMU in OP's pic is an APU used only in 3 space missions: STS-41-B by Robert L. Stewart and Bruce McCandless II, STS-41-C by James van Hoften and George Nelson (both missions used MMU #2), and STS-51-A by Joe Allen and Dale Gardner (MMU #3).

I very much wanted to be an astronaut, so I memorized shit like that.

Then my eyes went bad.
