There were cheers in the JPL control centre as the first photos of the flight arrived back on Earth. In the background, MiMi Aung could be heard saying: "It's real!"There were cheers in the JPL control centre as the first photos of the flight arrived back on Earth.

The demonstration saw the Mars-copter rise to just over 3m, hover, swivel 96 degrees, hover some more, and then set down. In all, it managed almost 40 seconds of flight, from take-off to landing.The demonstration saw the Mars-copter rise to just over 3m, hover, swivel 96 degrees, hover some more, and then set down.

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.Getting airborne on the Red Planet is not easy. The atmosphere is very thin, just 1% of the density here at Earth.

There's help from the lower gravity at Mars, but still - it takes a lot of work to get up off the ground.There's help from the lower gravity at Mars, but still - it takes a lot of work to get up off the ground.

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.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.
Control was autonomous. The distance to Mars - currently just under 300 million km - means radio signals take minutes to traverse the intervening space. Flying by joystick is simply out of the question.Control was autonomous.

Asked whether she was surprised the flight had worked, MiMi Aung said: "No, I'm not. We really had nailed the equations, the models and the verification here on Earth in our laboratory tests. So, it then became a question of: have we chosen the right materials to build Ingenuity, to survive the space environment, to survive the Mars environment?Asked whether she was surprised the flight had worked, MiMi Aung said: "No, I'm not.

"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."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.

Sample navigation images sent back to Earth revealed the helicopter's shadow on the floor of the crater as it came back in to land. Satellites will send home more pictures of the flight over the next day. There was only sufficient bandwidth in the orbiters' first overflight to return a short snatch of video from Perseverance, which was watching and snapping away from a distance of 65m. Longer sequences should become available in due course.Sample navigation images sent back to Earth revealed the helicopter's shadow on the floor of the crater as it came back in to land.

A successful maiden outing means that a further four flights will be attempted over the coming days, each one taking the helicopter further afield. "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 HÃ¥vard Grip, the Mars helicopter's chief pilot at JPL.
Monday's successful maiden outing means that a further four flights will be attempted over the coming days, with the first of these occurring as early as Thursday. Each succeeding flight will build on what has gone before.
"What we're talking about here is going higher, going further, going faster, stretching the capabilities of the helicopter in those ways," Dr Grip explained.
"We're putting the pedal down and going for it," added Dr Thomas Zurbuchen, the head of science at Nasa.

"It's really taking a tool that we haven't been able to use before and putting it in the box of tools that is available for all of our missions going forward at Mars. So for me, it's really exciting personally and for the community overall it opens up new doors," said Dr Thomas Zurbuchen, the head of science at Nasa. 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."
"We will be able to explore areas where we cannot use a rover. Some of these crater walls, for example, are so exciting; scientists have been writing papers about them." Bob Balaram, Ingenuity's chief engineer, said ideas for larger helicopters were already being discussed.
Nasa has already approved a helicopter mission to Titan, the big moon of Saturn. Dragonfly, as the mission is known, should arrive at Titan in the mid-2030s. "We are thinking of things in the 25-30kg class of vehicles, and those vehicles would carry maybe about 4kg of science instruments," he told reporters.
