On the way to "Winter Haven 3," the spot on the north face of "Home Plate" where NASA's Spirit rover is headed, the rover has driven into an area below a hummock (elevated area). Spirit has tried unsuccessfully during the past week to climb onto the hummock and make progress toward Winter Haven 3. Because it is critical to reach the north face while enough solar energy is available to get there, Spirit spends every available day driving. In-between drives, Spirit recharges the batteries and conducts very light remote sensing.
The rover's drive on sol 1378 (Nov. 18, 2007) ended early when Spirit's unusable, right front wheel got snagged on a buried rock, causing the rover to turn and drive into a "keep-out zone." Two Martian days later, on sol 1380 (Nov. 20, 2007), the drive faulted out again when the rover experienced more than 90-percent slip after traveling 3.6 meters (11.8 feet). The rover's handlers continue to work on strategies for enabling Spirit to drive away from the outcrop.
