NASA tests Mars rotors at Mach 1.08 to power next-gen SkyFall helicopters
TL;DR Summary
NASA and AeroVironment tested two Mars-bound rotor systems in JPL’s Mars simulator, reaching rotor tip speeds up to Mach 1.08 (about 3,750 rpm) under simulated Martian conditions—surpassing Mars’ speed of sound and signaling feasibility for larger SkyFall rotorcraft that could carry bigger instruments and longer missions, building on Ingenuity’s historic Mars flights.
