Next-gen Mars helicopter rotor blades exceed Mach 1

Phys · · 901 words · By NASA
Technological Innovation space exploration Aerospace Engineering

NASA's Jet Propulsion Laboratory successfully tested next-generation Mars helicopter rotor blades that exceeded Mach 1 in a simulated Martian environment. The tests demonstrate that these rotors can safely handle supersonic speeds, allowing future aircraft like the SkyFall project to carry heavier scientific payloads.
