Designing A Mars Rover To Launch In 2020

The Mars 2020 rover, Perseverance, is based on the Mars Science Laboratory‘s Curiosity rover configuration. It is car-sized, about 10 feet long (not including the arm), 9 feet wide, and 7 feet tall (about 3 meters long, 2.7 meters wide, and 2.2 meters tall). But at 2,260 pounds (1,025 kilograms), it weighs less than a compact car. In some sense, the rover parts are similar to what any living creature would need to keep it “alive” and able to explore.

The Perseverance Rover Has The Following Parts:

body:a structure that protects the rover’s “vital organs”
brains:computers to process information
temperature controls:internal heaters, a layer of insulation, and more
“neck and head”:a mast for the cameras to give the rover a human-scale view
eyes and ears :cameras and instruments that give the rover information about its environment
arm and “hand”:a way to extend its reach and collect rock samples for study
wheels and legs:parts for mobility
electrical power:batteries and power
communications:antennas for “speaking” and “listening”
