The flight tests of the helicopter for Mars ended successfully

NASA successfully experienced a helicopter, which from 2021 to fly on the surface of Mars. The tests took place in a special chamber, which copy atmospheric and physical conditions of the Red Planet.

In 2020, the aircraft will be delivered to the surface of another world inside the carcass. However, the conditions there are significantly different from the Earth. The device should function at temperatures up to -90 ° C 100 times less dense atmosphere and with a third of gravity, familiar to us.

The tests were held in a cylindrical vacuum chamber with a diameter of 7.62 m, from which the entire air appeared, and then filled with carbon dioxide, which prevails on Mars. For gravitational unloading, a motorized belt was attached to the helicopter, which performed the role of a constant tug, equivalent to 2/3 of the forces of earthly attraction.

Despite the small size, the model consists of more than 1,500 elements from carbon, aluminum, silicon, copper, foil and foam materials, so scientists were worried if they could work in such extreme conditions as a single mechanism. Although everything went, as the engineering models predicted, but total all flights lasted only about 1 minute and passed at an altitude of 5 cm, but it was to make sure normal operation.

The purpose of the MARS Helicopter project is to study the concept of aircraft in real conditions of the Red Planet. To do this, he will make short flights (90 seconds), and the rover with which he will arrive will engage in the geological assessment of the landing zone, the search for signs of ancient life,
