RE: Starlink 22 + Helicopters on Mars [Live: 24.03.2021, 08:58 UTC]

Yeah, this Mars stuff is really fascinating. It will be extremely interesting to see if they can make that thing fly. I didn't watch the video but from the picture I'm assuming its going to be using a "helicopter" rotor? I wonder how fast that thing has to spin to create enough lift to keep it in the air. I love reading about this stuff on Stem. Thanks for posting.

Sort:  

2 counter rotating rotors, going at 2400 rpm (tips going close to 0.7 Mach)
