The Mars 2020 rover is getting prepared to land on the red planet next year. Engineers at NASA’s Jet Propulsion Laboratory (JPL) are completing the rover by installing its wheels and suspension system.
There are six wheels, for now, are only engineering models used for fitting and testing, These wheels will be replaced once the rover launches.
Each wheel is 20.7 inches in diameter and has a self integrated motor that helps rover to move forward. These wheels will support rover to stay relatively upright even when wheels move in different positions and angels.
Rover wheels can dig into the soft sand and are constructed in a way that it can move effortlessly on hard rocks.
To prevent any contamination, engineers of NASA wear protective gear while installing the wheels and legs.
