The LMP (left) keeps a lanyard in tension while the CDR (red arm and leg bands) pulls out the wheel-wound, righthand tape to drive the semi-automatic deployment sequence. A combination of gravity, springs, carefully placed mechanical supports, and a judicious tug or two on the lanyard by the LMP will lead to the various parts of the Rover snapping into place in the proper sequence as the CDR pulls out the righthand tape. Here, the aft portion of the Rover chassis and the aft wheels are about to snap into positon.
