the density of The atmosphere on Mars is about 1 percent of that on earth. To the 1.8 kilograms of heavy helicopter test, the researchers would be on the unit at a height of 30.480 metres to fly, which is far from practical.

In this simulator were on different days, and two successful test flights take place, so let NASA know on his website.Read also SpaceX boss Musk reveals price tag of journey to Mars
The atmosphere of Mars has not only a different density than that on earth, also the temperature is much lower; up to -90 degrees Celsius.

The nitrogen and the oxygen were then replaced by carbon dioxide, the major constituent of the atmosphere of Mars.
