JPL engineers played Bob Marley's "Get Up, Stand Up" in the control room as they watched new images confirming that the Mars Exploration Rover Spirit successfully stood up on its lander late Thursday night Pacific time, a major step in preparing for egress. This image from the rover's front hazard avoidance camera shows the rover in the final stage of its stand-up process. The two wheels on the bottom right and left are locked into position, along with the suspension system. The martian landscape is in the background. With a deflated airbag partially blocking one exit route, engineers will decide whether Spirit should use a different route to roll off the lander. Credit: NASA/JPL
