NASA on Monday successfully conducted the first controlled flight on another planet — its Mars helicopter Ingenuity flew a short flight in what the agency described as "a Wright Brothers moment" in space.
At about 3:30 a.m., the twin, carbon-fiber rotor blades began spinning furiously, and the chopper, called Ingenuity, lifted off the surface of the Red Planet, reaching an altitude of about 10 feet, where it hovered, turned and landed softly in an autonomous flight that lasted just 30 seconds, the space agency said.
NASA flew the 4-pound craft for 39.1 seconds to an altitude of about 10 feet above the surface. The helicopter's rotors spun to more than 2,500 revolutions per minute, far faster than a helicopter on Earth due to the thin atmosphere of the Martian environment.
The flight was autonomous, given the 15-minute delay in communication's between NASA's location in California and the surface of the red planet.
Confirmation came via a satellite at Mars which relayed the chopper's data back to Earth.
The space agency is promising more adventurous flights in the days ahead.
It would be recalled that the rotocraft was carried to Mars in the belly of Nasa's Perseverance Rover, which touched down in Jezero Crater on the Red Planet in February.
Perseverance deployed the helicopter from underneath the rover earlier this month, with NASA performing a long list of preflight checks during the past two weeks. Perseverance captured Ingenuity's flight while parked about 211 feet away, and acted as a communications relay between JPL's mission control and the helicopter.
The helicopter carried a tiny piece of fabric from the wing of Flyer 1, the Wright brothers' aircraft that in 1903 made the first powered flights on Earth.
"Like the Wright brothers at Kitty Hawk, we know that our time to make a difference at Jezero Crater, Mars is not yet over – this is just the first great flight," JPL's MiMi Aung, the Ingenuity's project manager, said on the webcast.
