Astronauts

New Yorker - "The Martian Chronicles"
Burkhard Bilger

"While I was at [Jet Propulsion Laboratory], I heard talk of a survey, perhaps apocryphal, which asked astronauts if they'd go to Mars on a one-way trip. Three-quarters supposedly said yes. ("The pilgrims on the Mayflower didn't hang around Plymouth Rock waiting for a ship to take them back," the Apollo astronaut Buzz Aldrin later told me.)"
