The American space Agency NASA is considering together with the next Rover, which will fly to the Red planet in 2020, to send to Mars a miniature helicopter. This device could be the first flying mechanism on the planet. It is expected that it will be used not only for observations, how much directly to test its mechanism.
The Martian atmosphere is significantly less than earth’s, suitable for flying due to the motion of the propellers. Helicopters stay in the air above the Earth because its atmosphere is dense enough, and the screws can “push off” from the air. At the same time, the atmospheric pressure on Mars is about one hundred times less. This means that for the project the device should be lightweight and have large blades relative to their size. At the same time to rotate these blades must as soon as possible. It is expected that the unit will have a cubic shape and weigh about a kilogram, and the length of the blades will be about a meter. Martian helicopter will charge from the solar panels, which will allow it to make daily flights with a duration of 2-3 minutes and fly for about about half a kilometer.
According to experts NASA, potentially the helicopter,”the helper” would allow the Rover to explore daily three times larger area than would be possible solely with the help of cameras installed on Board.
Experts expect that the most difficult element of the work of the helicopter, which should be prepared carefully, is a landing after each “crash”. As explained by engineer Bob Balaram, landing is the most risky part of any mission.
Scientists from the American space Agency, also half-jokingly noted that the helicopter could, including to take pictures of the Rover on Mars, “paired” with which he is working, that would put a Martian selfie to a new level.Related posts:
