Goodbye, heat shield

The spacecraft ejected its heat shield when the rover was approximately 4 miles (6.4 kilometers) above the surface. According to Al Chen, Perseverance EDL lead at JPL, a spring responsible for pushing the heat shield away appears to have come loose. This didn’t affect the mission, but it obviously was not supposed to happen.
