After the last flight mission malfunctioned and fell to the surface of Mars, one of the rotor blades of the Ingenuity Mars helicopter was broken, which resulted in the Ingenuity helicopter never being able to take off. NASA has announced the end of all Ingenuity missions.
NASA could tell through the shadow of the blade that the front end of one of the blades was broken. NASA wanted to see what the situation looked like now, so it decided to add a final mission to Ingenuity.
The main content of this mission is to make the small floating rotor twist to facilitate the damaged blades to rotate out of the blocked area, so that the Perseverance Mars rover can take pictures of it.
Below is a shadow showing the damage to the front of the blade:
