NASA Pushes Mars Helicopter Rotors Past Mach 1 in Ground Tests
NASA’s JPL tested next‑gen Mars helicopter rotors in the 25‑Foot Space Simulator, evacuating air and replacing with CO2 to mimic Mars, pushing blade tips to Mach 1.08 with headwinds, boosting lift by about 30%, a key step toward heavier scientific payloads as SkyFall plans to deploy three rotorcraft to Mars by December 2028.
