First flight on another planet
NASA have successfully flown their helicopter on Mars.
This is the first time that a man-made object has flown on another planet, The helicopter called Ingenuity has a piece of material from the Wright Brother first aircraft.

Re: First flight on another planet
Quite an achievement given how thin the atmosphere is on Mars.

Re: First flight on another planet
I think they have to spin the rotors insanely fast to get the lift they need. All in all an absolute marvel of engineering. Great to see some actual video from the surface as well ... they don’t normally bother trying to put video cameras on their rovers as nothing moves fast enough to be worth the effort.

It's a lot thinner than that. The atmospheric pressue on Mars is about 1% of that at sea level here and mostly carbon dioxide. IIRC everest is about 30%

Re: First flight on another planet
One Nasa Engineer I listened to said that the atmosphere on Mars isn't thick enough to be much help when flying, but is too thick to ignore.
Amazing achievement.

Re: First flight on another planet
I imagine the gadget had been tested on Earth in a suitably pressurised room/tank. So it was always going to work in the weaker gravity.

I didn't think they'd go in unprepared. That little copter would have gone through a lot of earth bound testing at every stage, from modelling the initial design to flying the built craft.
Still cool though.

Re: First flight on another planet
Maybe in the future, larger ones could be used to scatter seeds (cacti ? ) and see if they grow?
Might need bigger ones for bags of compost though

 I love it.
They would have done a lot of simulation hours on a computer.

They did real tests, in a vacuum chamber.

Maybe you're too close . . . try standing much much further away?
edit:
Nasa's rover makes breathable oxygen on Mars

Things are looking very impressive . . they'll be planting forests next. How long before man spends a week there?
