Yup. I get the impression this was a forced landing, it put itself down on too steep a slope and caused a rotor strike. Helicopters do not like unbalanced rot

Yup. I get the impression this was a forced landing, it put itself down on too steep a slope and caused a rotor strike. Helicopters do not like unbalanced rotors! And think of what happens if it fails at speed: The rotors are 4' across, so 2' from tip to hub. 2,400 rpm for the low end of flight speed. That's 40 rotations per second, the average speed of a rotor is therefore 40 rps * 2' * (2 * pi {path traced by the rotor}) / 2 {for the midpoint of the rotor} = 251 feet per second = 172 miles per hour. A rotor yeeted at 172 miles per hour will go quite a ways on Mars (especially since it's on a slope--it could be lobbed at an angle, not merely flat) and there's a very, very expensive spacecraft nearby. (And it must be nearby--Ingenuity can't talk to Earth. You can't back off to a safe distance and try it.)
