Normally i'm all over things done on other planets/asteroids or anything to do with space. But i have to admit i was rather "Meh" over this. I sort of see how it could open up more discoveries. But it just hasn't gripped me.

Think of the engineering though. Mars has a very thin atmosphere so the engineering solution used to generate sufficient lift here could increase the efficiency of terrestrial helicopters.

I know its a bit sad but I like quickbuild kits!!!

If I recall correctly only 0.1% as thick as Earth's. Based we're spinning at 2,400rpm. They apparently used two contra rotating blades.

Without going deeply into propulsion and aerodynamics. Mars also has only a 1/3 of the gravity that the earth does. So it would require vastly less 'lift' to counter the weight and gravitational effect to get airborne. High cord and counter rotating props as mentioned above plays right into this.
