I heard this week that someone was proposing that any expeditions to Mars be a one way trip for the astronauts. While it could definitely have its advantages such as putting colonization of Mars on the fast track, one big problem remains….its a one way trip. Maybe we are in the 1400s of space travel, but who would sign up for such a thing.
