Mars 2020 rover News
Every wheel has its own motor. The two front and two rear wheels also have individual steering motors that enable the vehicle to turn a full 360 degrees in place.
The goal of the Mars 2020 rover is to look for signs of ancient life. It will be the first spacecraft to collect samples of the Martian surface, caching them in tubes that could be returned to Earth on a future mission, Xinhua news agency reported on Thursday.
Earth has a limited supply of Martian meteorites, which scientists determined were blasted off Mars' surface millions of years ago.
JPL is also developing a new landing technology that will allow the rover to visit sites deemed too risky for Curiosity and shave miles off its journey.
After Pathfinder (1997), the Spirit and Opportunity rovers were designed with 10 cameras each, including on their landers; Mars Science Laboratory's Curiosity rover has 17.
The Mars Exploration Program with a planned launch in 2020 builds on the success of prior rovers, to make coordinated measurements that could detect signs of ancient life - or bio-signatures - in their original spatial context.
Throughout its investigation, Mars 2020 will collect samples of soil and rock and cache them on the surface for potential return to Earth by a future mission.
