In a California test chamber designed to mimic the near-vacuum of another world, NASA engineers crossed a threshold that redefines what flight can mean beyond Earth. By spinning rotor blades past the speed of sound inside a simulated Martian atmosphere, the Jet Propulsion Laboratory has answered a question that once seemed unanswerable: can a machine fly fast enough to lift itself on a planet where the air is almost nothing? The answer, confirmed across 137 tests, is yes — and three helicopters will carry that answer to Mars in 2028.
