I heard on the news that Spirit was unable to drive today because of a pointing error with the High Gain Antenna. Turns out it was too cold in the morning because it was in the shadow of the Pancam mast.
They use hard stops to calibrate the HGA position and they know they hit the hard stops when the current reaches a certain limit. The limit was set too low for the extreme cold. Very minor problem and they got the HGA to work perfectly later in the day, but the day was wasted troubleshooting. |
