Question

Did NASA astronauts ever carry cyanide capsules in case of being stranded in space? Is it documented somewhere

Answer 1

No.  If they wanted to die, all they'd have to do is pop open the hatch.

Answer 2

They carried somethng much more lethal, Tang. No, really i've never heard of that unless aliens would be interrogating them.

Answer 3

No.  Reporters once asked Jim Lovell (of Apollo 13) if he had a cyanide capsule, and he said no, since opening the hatch is far easier anyway.

However, Soviet astronaut Alexey Leonov said he had a cyanide capsule inside his helmet when he did his historic spacewalk.  However, this probably wasn't something mandated by the state.
