While all six wheels have engines, the front and rear have engines that will allow Mars 2020 to make a full turn at 360 degrees. In addition, the suspension system can withstand gradients up to 45 degrees in any direction, so the riveter can ride on quite large rocks without overturning. The team will use the running wheels only for testing and they will be replaced for ready-to-fly models somewhere next year. mounted camera, as well as other motors and components made to collect samples of Martian rocks and soil.
