Listen to this: NASA releases audio of Mars helicopter in flight – NewsCenterMaine.com WCSH-WLBZ
This is what the Mars Ingenuity helicopter — the first powered aircraft on another planet — sounds like from a distance.
CAPE CANAVERAL, Fla First came the amazing pictures, then the video. Now NASA is sharing sounds of its little helicopter humming through the thin Martian air.
NASAs Jet Propulsion Laboratory in California released this first-ever audio Friday, just before Ingenuity was set to soar on its fifth test flight. The low hum from the helicopter blades spinning at more than 2,500 revolutions per minute is barely audible. It almost sounds like a low-pitched, far-away mosquito or other flying insect.
