NASA's rover Perseverance will try to land on Mars today. NASA's Al Chen says for the first time cameras and a microphone will record entry and landing.
At around 3:55 this afternoon the rover will descend from orbit during what is known as seven minutes of terror. It has to decelerate from 12-thousand miles per hour to two-miles-per hour during that seven minutes. The rover originally launched here from Cape Canaveral at the end of July.
NASA TV will live-stream the landing, and the visitor complex will stream the coverage on a large video screen starting at 2 PM.
