Summary | 8 Annotations
The American space agency has successfully flown a small helicopter on Mars. The drone, called Ingenuity, was airborne for less than a minute, but Nasa is celebrating what represents the first powered, controlled flight by an aircraft on another world.
2021/04/21 12:56
The rotorcraft was carried to Mars in the belly of Nasa's Perseverance Rover, which touched down in Jezero Crater on the Red Planet in February.Ingenuity Mars helicopter set for historic flightNasa shows dramatic video of Mars rover's landingWill Nasa's next rover discover life on Mars?
2021/04/21 12:56
"We can now say that human beings have flown a rotorcraft on another planet," said a delighted MiMi Aung, project manager for Ingenuity at Nasa's Jet Propulsion Laboratory (JPL) in Pasadena, California."We've been talking for so long about our 'Wright Brothers moment' on Mars, and here it is."
2021/04/21 12:56
Getting airborne on the Red Planet is not easy. The atmosphere is very thin, just 1% of the density here at Earth. This gives the blades on a rotorcraft very little to bite into to gain lift.There's help from the lower gravity at Mars, but still - it takes a lot of work to get up off the ground.
2021/04/21 12:57
Ingenuity was therefore made extremely light and given the power (a peak power of 350 watts) to turn those blades extremely fast - at over 2,500 revolutions per minute for this particular flight.
2021/04/21 12:57
"We've gone from 'theory says you can' to really now having done it. It's a major first for the human race," she told BBC News.Ingenuity has two cameras onboard. A black-and-white camera that points down to the ground, which is used for navigation, and a high-resolution colour camera that looks out to the horizon.
2021/04/21 12:57
The International Civil Aviation Organization (ICAO) - the United Nations' civil aviation agency - has also presented Nasa and the US Federal Aviation Administration with an official ICAO designator: IGY. "India Golf Yankee, with the call sign 'Ingenuity', and those details will be officially included in the next edition of ICAO's designators for aircraft, operating agencies, aeronautical authorities and services," explained Håvard Grip, the Mars helicopter's chief pilot at JPL.
2021/04/21 12:57
Michael Watkins, JPL director, said: "What the Ingenuity team has done is given us the third dimension; they've freed us from the surface now forever in planetary exploration, so that we can now make a combination of driving on the surface and sampling the surface, doing reconnaissance, and even scientific experimentation on inaccessible places for a rover. This is exactly the way we build the future."
