Learn about rover
deployment and egress

When the lander structure first opens, the rover is so tightly folded that it's almost unrecognizable. Then, piece by piece, it takes shape. The entire deployment process takes five sols and involves many steps. Scientists and engineers back on Earth want to make sure that each step is successfully completed before they move on to the next. This type of control is necessary to avoid any complications that might arise due to the angle of the lander, the abundance of rocks in the landing area, or other environmental issues. After the camera mast, antennas, wheels and solar arrays are deployed, the rover will send its first radio transmission to Earth.
