NASA’s Perseverance spacecraft carries 23 cameras, including 7 for entry, descent and landing documentation. For the first time, we will see hi def video of the car-sized rover as it rides its massive supersonic parachute, fires its rockets for powered descent and then is lowered to the surface of rugged Jezero crater from the sky crane. Should make for some interesting viewing!
