CALIPSO Instrument Operational

Thursday, September 11, 2014

The CALIPSO payload is back in data acquisition mode as of Wednesday, September 17, 2014.  CALIPSO data processing has returned to a nominal state, and data has been generated to current.


Due to elevated solar activity, CALIPSO payload was commanded to SAFE mode during the 10:45 UTC pass on Thursday, September 11, 2014.  The CALIPSO Mission Operations Team is monitoring the space weather environment and is working with CNES to return to nominal operations once conditions improve. Notification will be provided once CALIPSO is back in data acquisition mode. Science data is not acquired while the payload is in SAFE mode.
