Ingenuity's last flight


Recommended Posts

Looks like the tip of one of Ingenuity's rotors touched the ground as it was trying to land.  These rotors need to rotate at almost 3,000rpm to keep the vehicle aloft in the extremely thin Martian air.  They also need to be extremely light because they had to be launched from Earth and every ounce adds to the cost of the launch.  Accordingly they're made of carbon fiber.  As you might expect, when such a rotor contacts the ground at that speed the result is severe damage to the rotor and the loss of the ability to fly.  :(
