Many fans of space look forward to summer 2020, it then begins a mission during which the Mars 2020 and the accompanying helicopter will fly to the Red planet to find out, whether there was it ever life. Recently, space Agency NASA announced the successful test of the Rover — the researchers believe that it ready to landing on the planet without intervention. A week later there was another good news, saying that the helicopter has proven its ability to fly in the Martian conditions. Testing was conducted in a special chamber with carbon dioxide.
The experiment took place in laboratory of jet movement NASA in the neighborhood of Los Angeles. The Martian conditions were recreated in the chamber with a width of 7.62 metres: first, the researchers dug out all the nitrogen, oxygen and other gases, and then filled with carbon dioxide, the primary part of Mars ‘ atmosphere. To make sure that weak gravity, the scientists used a system of gravitational unloading — strap on the top of the helicopter, providing power equal to two-thirds of earth’s gravity.
During the two test UPS the helicopter rose 5 inches to make sure that the machine could fly in the Martian conditions, and it was enough. Previous tests proved that the helicopter is able to withstand sudden changes in temperature, where it helped the internal heater.
The helicopter, weighing 1.8 kilograms and a box shape is equipped with a camera to detect interesting for studying surfaces. In support of the Mars 2020, it will also collect information to set up roots for later missions. Having studied his behavior, engineers can build superior vehicles for missions to Mars, correcting all errors found.
