Aqua Safe Mode Event

Submitted by dolink on Sun, 04/17/2022 - 14:34

The Aqua spacecraft entered a safe state after an unexpected power controller swap on March 31, 2022 (2022/090 @17:59:08z). This caused the MODIS instrument to also enter safe mode. After analysis and recovery of the spacecraft, MODIS was transitioned to full science mode via outgas from April 13-15, 2022. Aqua MODIS returned to nominal temperatures and operational status for all bands on April 17, 2022 03:00:00z. MCST will perform additional calibrations and will continue to monitor the performance of the detectors following the safe mode event.
