Stardust in safe mode over the last weekend
http://stardustnext.jpl.nasa.gov/mission/m...tatus09_q4.html QUOTE October 31, 2009—Special Report
At the start of Thursday’s DSN pass Stardust-NExT was acquired in safe mode. Analysis of the recorded data showed the spacecraft entered safe mode late Monday evening.The Attitude Knowledge Performance Monitor requested safe mode because the Star Camera failed to respond to commands issued by the processor. Also impacted were the CIDA instrument and the Sun Sensor. Both of these components were not able to communicate with the processor. The Sun Sensor returned to nominal operations during the safe mode execution and the Star Camera returned to nominal after it was power cycled as part of the response by the Safe Mode Executive. CIDA will be returned to nominal operations during our DSN pass on Monday, November 2. This safe mode was nearly identical to the Oct 2003 safe mode event. That entry was caused by a solar flare that caused communications problems with the Star Camera, Sun Sensor, CIDA and Navigation Camera. Interestingly, that same day in October 2003, the Genesis and Odyssey spacecrafts also entered safe mode due to the same solar flare. The investigation into the cause of the current event is continuing. The spacecraft team successfully exited safe mode during Saturday’s afternoon pass and returned spacecraft operations to normal. |
