Will be interesting to see how it actually does.

Progress is being made, slowly but surely...

 

I hope they go through with it.

Title of the article definitely led me to believe something else - but this seems to have some valid, and potentially really interesting, results!

Oh we're going through with it.  The helicopter has been integrated onto its platform on the M2020 rover which is undergoing final integrated testing and will be shipping to KSC in just a few short months.  It's happening!

 

P.S. live view of the high bay at JPL:

Yes, at first I said huh...

But might work if they're sure they have things right.

Guess we'll wait to see if this little bird flys.

I wonder if NASA has tested the concept in a chamber where atmospheric density is equivalent to that of Mars?

They sure did!  https://www.nasa.gov...es-flight-tests

 

I balked at the idea of a Mars helicopter when I first heard it because Mars’ atmosphere is only about 1% as thick as Earth’s.  It turns out that the flight dynamics aren’t too dissimilar.  In order to generate the same amount of lift in Mars air, the rotors have to turn 10x faster than in Earth air.  However, the gravity on Mars is ~1/3 that on Earth, so the helicopter only needs to generate 1/3 as much lift to lift itself, and the rotors only need to spin ~3x faster to lift the helicopter on Mars than on Earth.

 

Now I wonder how it will handle Mars winds..

That's great!   Would leave to see more exploration of Titan and Enceladus.  It says there is enough sunlight to see on Titan but not enough for energy?  Does that mean many of the UV rays are filtered, meaning it's a very think atmosphere?
