A Helicopter Flies on Mars

Ingenuity Shadow

Deployed from NASA’s Perseverance rover, the Ingenuity helicopter took off and hovered for about 30 seconds in its first flight early this morning.

The solar-powered helicopter first became airborne at 3:34 a.m. EDT (12:34 a.m. PDT) — 12:33 Local Mean Solar Time (Mars time) — a time the Ingenuity team determined would have optimal energy and flight conditions. Altimeter data indicate Ingenuity climbed to its prescribed maximum altitude of 10 feet (3 meters) and maintained a stable hover for 30 seconds. It then descended, touching back down on the surface of Mars after logging a total of 39.1 seconds of flight. Additional details on the test are expected in upcoming downlinks.

Ingenuity’s initial flight demonstration was autonomous — piloted by onboard guidance, navigation, and control systems running algorithms developed by the team at JPL. Because data must be sent to and returned from the Red Planet over hundreds of millions of miles using orbiting satellites and NASA’s Deep Space Network, Ingenuity cannot be flown with a joystick, and its flight was not observable from Earth in real time.

NASA livestreamed the team in Mission Control as the test results were transmitted back to Earth. The photo above is of Ingenuity’s shadow taken while in flight by its onboard camera.

Update: Here’s video footage of the first flight:

The world’s oldest living person was alive when the Wright Brothers flew at Kitty Hawk and when the first helicopter flew on Mars.
