Why does the downlink operator have what appears to be Github open? He seems to be carefully monitoring it. Is raw data going straight to Github?
The video feed had a "university team" feel to it that was sort of unexpected and nice :)
I was surprised to see the tack sharp shadow on the image from the downwards facing navigation camera. My thinking was that the rotors needed to spin way faster on this drone than on a drone on earth, because of how thin the atmosphere is on mars. But the sharpness seems to indicate that the rotor speed is perhaps all that different! Or perhaps the whole thing is just so light that there is not so much mass to lift up?
Only negative thing I can think of is that I really hope the Perseverance rover has better video onboard just not transmitted yet. Maybe they will release it during the press conference later today. The one they showed was a little clipped. It had spin up. then it sort of cuts to the mid flight and then cuts to the spin down... all the takeoff and touchdown excitement is totally missing from the video they showed. If I didn't know as much as I do about how image telemetry is handled... I'd actually have thought it was broken, thats how abrupt the transition is in the video.

Yay! Cool that they made it :) The video feed had a "university team" feel to it that was sort of unexpected and nice :) I was surprised to see the tack sharp shadow on the image from the downwards facing navigation camera.
