NASA experts have found on the Rover “Perseverance” (Perseverance) future of the mission “Mars-2020” unmanned helicopter in the flight configuration, and refueled tanks brake system “sky crane” to lower the Rover to the Red planet in February 2021, reported on the website NASA.
Unmanned Mars Helicopter was developed in the framework of the program “Mars-2020” to study hard to reach places on the red planet and conduct reconnaissance. The drone’s weight is 1.8 kg, it has two coaxial bearing contrariwise screw with a diameter of 1.2 meters each. The machine is power provide batteries, podzaryadit from solar panels. In addition, the helicopter is equipped with a color camera and navigation systems and data transmission.
Test the drone, which confirmed its ability to fly in conditions of the Martian atmosphere, was fully completed in March 2020. On April 6, the engineers hooked up 34 electrical connection between Rover “Perseverance”, helicopter flight and capsule for him, located on the lower part of the body of the Rover. After that all circuits were checked and experts were convinced that the drone receives electric power from the Rover and is able to transmit and receive data from it. The deployment of the drone on the red planet will begin after the Rover will discover a convenient place, leave the drone and drive off a hundred meters. After this, a helicopter will check your system, make a trial a 30-second lift to three meters, and then carry out five long-haul flights, lasting 90 seconds, which will rise to a height of several hundred meters. The whole flight campaign will take a month.
Before the start of the mission is 14 weeks, and landing near the crater Lake on Mars needs состояться18 Feb 2021. Currently, there are the final work on the Rover. Previously, he received the parachute, and in early April, 401 pounds of monopropellant hydrazine was added to the four fuel tank brake system “sky crane”, which with the help of eight engines will have to reduce the speed of the device with 80 meters per second (at a height of 2200 meters) to 0.75 meters per second (at a height of 20 meters from the surface of Mars), and then later with the help of nylon ropes Rover on Mars.
Earlier we talked about the mission of the Dragonfly, in which 2034 on Titan landed wasmerely drone, which will study the surface and atmosphere of Saturn’s moon for nearly three years.
