NASA's Mars Exploration Rover Opportunity rotated its wheels on sol 463 for the first time since the rover dug itself into a sand dune more than two weeks earlier. The wheels made about two and a half rotations, as commanded, and the results were a good match for what was expected from tests on Earth, boosting the confidence of mission managers that they can get the rover out of the dune. In the loose footing, the rover advanced 2.8 centimeters (1.1 inch) forward, 4.8 millimeters (0.19 inch) sideways and 4.6 millimeters (0.18 inch) downward. After further analysis of the results, the rover team will decide whether to repeat the same careful movement again on sol 465. Meanwhile Opportunity's main tasks for sol 464 were remote-sensing observations.
Opportunity has started moving its wheels again after a couple weeks of holding still while taking some amazing images. While waiting for the rover team to finish tests for planning the best strategy for driving out of a sand trap, Opportunity has been busy taking a comprehensive color panorama of the area. On sol 461 (May 11), Opportunity straightened its wheels. After checking data and images confirming the success of that move, the team planned commands for beginning to rotate the wheels on sol 463 (May 13). The rover is healthy and ready to go... |
