The poster of the astronaut crew made me laugh. The male members of the crew, except for Hibito, all have names that are puns on musicians' names.
Freddie Saturn =
Freddie Mercury
Buddy Waters =
Muddy Waters
Damien Kweller =
Damien Rice +
Ben Kweller
The very common name "Karen Jones" does not have any obvious referents, except maybe to
Grace Jones. Linda Cliff might be a reference to reggae singer
Jimmy Cliff. Both Jones and Cliff are Jamaicans so they do have that in common.
