Crewed Mars landing

Projection

Humans set foot on another planet for the first time.

A Mars mission needs months of transit, landing a heavy ship through a thin atmosphere and returning. It would be the farthest humans have ever travelled and a first step toward living beyond Earth.

Why it’s plausible: Fully reusable super-heavy rockets and orbital refuelling are in testing; it depends on life support, radiation protection and propellant production on Mars working reliably.
