Whereas NASA and different area companies world wide have despatched landers, orbiters and rovers to the Crimson Planet, nobody has tried to fly an plane on one other planet earlier than. On Mars the environment is far thinner than it's on Earth, which implies there's much less air to generate raise and extra technical challenges in designing a craft that can keep aloft.
The helicopter, named Ingenuity, will not be the principle focus of the rover. Perseverance’s largest aim is to search for indicators of life on Mars and dig up samples of grime that would someday be returned to Earth for research. However engineers managed to search out room underneath the rover’s stomach to stow the tiny helicopter. Sooner or later throughout Perseverance’s journey, the rover will deploy Ingenuity onto the floor of Mars, the place it'll spin up its rotor and try to take off.
All of those flights should be autonomous, due to the lengthy lag time in communication between Earth and Mars. The workforce will ship an inventory of instructions to Ingenuity, and it'll carry out the entire steps by itself. The plan is for the helicopter to seize photos when it flies, and it’s doable that Perseverance can also snap some far-off photos of Ingenuity hovering within the air.

Ingenuity employs twin, counter-rotating blades operating at nearly 3,000 rpm, a fee that's about 10 occasions quicker than a helicopter on Earth as a way to chunk into the Martian ambiance, which about 100 occasions thinner than Earth’s. “Getting our helicopter into a particularly skinny ambiance is barely a part of the problem,” mentioned Teddy Tzanetos, take a look at conductor for the Mars Helicopter, again in mid-2019.
fter touchdown on the floor of Mars, Perseverance will launch a small helicopter referred to as Ingenuity from its underside. “We as human beings have by no means flown a rotorcraft, a helicopter, anyplace exterior of Earth’s ambiance, so it’s actually a Wright Brothers second on one other planet,” mentioned MiMi Aung, Ingenuity’s lead engineer, through the press convention.
