NASA is preparing to land the Perseverance Rover, along with the first small helicopter, on the red planet next month. Perseverance will be the fifth rover that NASA has attempted to land on Mars. While NASA has a successful record with landing its last few rovers on Mars, Matt Wallace, Mars 2020 deputy project manager, said this one is different. NASA Mars 2020 entry, descent and landing lead Allen Chen described this part of the mission as the “most critical and most dangerous” saying “mission success is never assured.”AdThere is a reason NASA engineers refer to minutes leading up to landing on Mars as “seven minutes of terror.” The spacecraft carrying Mars 2020 will hit the Martian atmosphere traveling at over 12,000 mph using its thrusters to steer toward its landing target. One is on Mars 2020′s SuperCam, the head of the rover, and another that will record the entry, descent and landing.
