Flying a helicopter on Mars is so damn hard but NASA made it possible. For the first flight, the helicopter took off, climbed to about 10 feet (3 meters) above the ground, hovered in the air briefly, completed a turn, and then landed. It was a major milestone: the very first powered flight in the extremely thin atmosphere of Mars, and, in fact, the first such flight in any world beyond Earth.

Being able to fly a helicopter or drone on Mars is very important as they can cover 24 kilometers in an hour. By the way, Curiosity took nine years to travel less than 25 kilometers.
