PASADENA, Calif. -- NASA's rover project team is using the Spirit rover and other spacecraft at Mars to begin developing the best maneuvers for extracting Spirit from the soft Martian ground where it has become embedded. A diagnostic test on May 16 provided favorable indications about Spirit's left middle wheel. The possibility of the wheel being jammed was one factor in the rover team's May 7 decision to temporarily suspend driving Spirit after that wheel stalled and other wheels had dug themselves about hub-deep into the soil. The test over the weekend showed electrical resistance in the left middle wheel is within the expected range for a motor that has not failed. THERE IS MORE TO READ AT THE LINK ABOVE.
