I think Percy thought it was a lawnmower, or perhaps channeling it's inner Zamboni for a bit... look at those tracks.

Calibration maybe ?

If this is the first controlled flight on Mars, then I take it that EDL was done via a wing and a prayer. :wink:

First powered aerodynamic flight, you get the idea.

I'm trying to wrap my head around that video clip of Ingenuity flying - that's an aircraft on another planet in full color.

Try holding the mouse button and move.

AWESOMENESS!!!

Also, is it true Ingenuity carries part of the Wright Flyer?

Yes it does, so did the Apollo 11 moon lander

Why, do you think, it's flying?

And that's how they reached the Moon.

The special old, wooden magic is shared between them.

Didn't they forget to put it on Voyagers?

I wonder how powered that landing was. It appears to have fallen slower than freefall, but ... one of the screwy things about Mars is that freefall isn't anywhere close to what we're used to, so all our perceptions of gravity in videos like that are widely off.

It looked to be travelling at constant speed, which means it was powered T = mg during descent.

Yeah, it looked to me like it dropped quickly at first then slowed its RoD

This makes sense as in suicide burn, optimal trajectory here is to get

Can it do oxygen extraction if the atmosphere is too rich in oxygen as well? That function is crucial in case you accidentally fill your habitat module with a hydrogen-oxygen mix during an attempt to make water from hydrazine.

Recently I read an article that the quadrocopter has already been successfully tested on Mars. But I'm wondering if this will be the last flying vehicle on this planet?

Almost certainly the Ingenuity drone will be followed up by larger and more capable vehicles now that the technology has been proven. But it might be a while before designs are converted into hardware on Mars.
