MARS 2020 SPECS
The Mars 2020 Rover is car-sized: about 3 metres long, 2.7m wide, and 2.2m tall, with an arm that can extend 2.1m. At 1050kg it weighs around 200kg less than a compact car.
Based on Curiosity, the Rover has narrower, more robust wheels, a stronger arm to accommodate the increased instrumentation, a bigger, faster computer system and the all-important sample cache.
