Mars

The humans managed to transport a helicopter weighing 1.8 kg to the red planet. The journey there lasted six and half months. The helicopter is able to fly there, even though the atmosphere on Mars has a pressure of only 680 Pa. To compare, air as thin as this one occurs at the altitude of 22 km on Earth.

On Earth, the record for the highest helicopter flight is 12.4 km.
