Open source flies on Red Planet
Today NASA’s Ingenuity helicopter became the first craft to be flown remotely on another planet. The Ingenuity team at the agency’s Jet Propulsion Laboratory in Southern California confirmed the flight succeeded after receiving data from the helicopter via NASA’s Perseverance Mars rover at 6:46 a.m. EDT (3:46 a.m. PDT).
Ingenuity’s mission was essentially a technology demonstration to test the first powered flight on Mars. The helicopter rode to Mars attached to the belly of the Perseverance rover.
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 3 metres, with Ingenuity maintaining a stable hover for 30 seconds.
Mars has a significantly lower gravity – only one-third that of Earth’s – and an extremely thin atmosphere with only 1% the pressure at the surface compared to our planet. This means there are relatively few molecules with which Ingenuity’s two 1.2 metre wide rotor blades can interact to achieve flight. The helicopter contains unique components, as well as off-the-shelf-commercial parts – many from the smartphone industry – that were tested in deep space for the first time with this mission.
Both Perseverance and Ingenuity feature free and open source software (posts passim) extensively.
