Awesome.
The air at the surface of Mars is as thin as that of the Earth at an altitude of 105 thousand feet (20 miles).
But gravity (and thus wieght) is less. But it flew!
Maybe they can do the same for Venus.
Venus is the opposite. It has a denser atmosphere than earth. So maybe they can have robot driven drone zeppilins cruise Venus. Airships that would not get off the ground on earth but would fly at high altitude on Venus. Trouble is that they couldnt use "hot air" balloons on Venus because the air temp at the surface is already 900 degrees.
For higher altitudes on Venus, zeppelins would be perfect. Nitrogen and oxygen are lifting gases in Venusian atmosphere so "hot air" wouldn't be necessary. However, they would be probably unable to ever land.
The challenges of Venus are high surface temperature and atmosphere acidity - quite unlike Mars where atmosphere thinness is the problem and robots need heating.
