The entry, descent, and landing, which is also known as the 7 minutes of terror are this rover’s first challenge before even setting its wheels on the most challenging terrain ever to be discovered.  10 minutes before Perseverance enters Mars’ atmosphere the spacecraft, which had a role of supporting it, is removed allowing the Rover space to travel at 12-13 thousand miles per hour as it enters the Martian territory.
