Mach 1 = .Mars: 240 mps. Earth: 340 mps. I don’t know at what altitude it was measured (no sealevel), but…

Mach 1 =
.Mars: 240 mps.
Earth: 340 mps.

In comparison, the far less air pressure on Mars requires a different thought. The Mars helicopter will do 1,900 to 2,800 rpm with the blade-tips hitting greater than 0.7 Mach. Even with the lesser atmosphere I would image a very high-pitched whine when in flight. The main rotor of the old UH-1H Iroquois (AKA, “Huey”) gunship runs at 324 rpm.
