Washington: In a historic first, NASA has tested next-generation Mars helicopter design on both Earth and the Red Planet. On Earth, the US space agency tested a new rotor that could be used with future Mars helicopters at NASA's Jet Propulsion Laboratory in Southern California, spinning at near-supersonic speeds (0.95 Mach).
