The Void can be a scary place
In Andrew Chaikin's 1994, A Man on the Moon, I believe it was the astronaut who had to do
the EVA coming back from the Moon on Apollo 16 who said he gripped the Apollo CSM handrails
for dear life while working outside the spaceship, as he did not want to drift off into that Utter
Blackness (he couldn't see any stars through his visor).
