The third flight of the Martian helicopter Ingenuity Mars at 100 meters lasted 80 seconds (video)


Martian helicopter Ingenuity continues to deliverflight records in the atmosphere of the Red Planet. Less than two weeks ago, on April 19, the drone made the first atmospheric flight in the history of mankind on another planet, confirming the possibility of flying in a thin atmosphere using the principles of aeronautics used on Earth.

The first flight in the atmosphere of Mars, the density of whichmakes up only 1% of the density of the earth's atmosphere, lasted 39.1 seconds. Then Ingenuity took off to a height of 3 meters, hovered for a short time and landed at the take-off point. The second flight, made on April 22, lasted 51.9 seconds. The helicopter climbed 5 meters, hovered, made several maneuvers, filmed with the onboard color camera and landed.

The next, third record flight, wasimplemented on Sunday 25 April. The Ingenuity's airborne duration was 80 seconds, which is close to the 90 second maximum flight time for a helicopter battery. During the test, the drone rose five meters above the surface of Mars, flew in a horizontal plane at a distance of 50 meters, and then returned to the starting point and made a soft landing. At the same time, a speed of 2 m / s was achieved, which exceeded the maximum speed of the helicopter during test tests on Earth. During the flight of the record one hundred meters, the helicopter cameras (navigation black-and-white and color) were continuously filming the surface of Mars.


NASA specialists immediately began topreparation for the fourth flight of Ingenuity, since the total estimated time of operation of Ingenuity on Mars is only 30 Martian days (sol). The purpose of the fourth helicopter expedition has not yet been made public. Upon completion of the testing phase of the Ingenuity Mars capabilities, the Perseverance rover will leave it on the planet's surface and continue its journey.

As a reminder, Ingenuity was delivered on February 18to Mars, "imprisoned" inside Perseverance. The main goal of the helicopter is to prove the fundamental possibility of performing atmospheric flights in the thin space of Mars. Ingenuity Mars weighs 1.8 kg. The device is equipped with a minimum set of research equipment necessary for navigation and carrying out color and black-and-white photography.

The Ingenuity Mars powerplant is powered bybatteries that receive energy from a solar panel. The helicopter is driven by two coaxial propellers with a diameter of 1.2 meters, rotating in the opposite direction. The flight range does not exceed 300 meters, the battery life is limited to 90 seconds, and the Ingenuity Mars ceiling is only 5 meters. The research results will allow NASA engineers to make a decision on the possibility of creating full-fledged atmospheric aircraft for exploring not only Mars, but also Titan.
