Update #3: According to the recovery planning, the Jason-2 spacecraft is to switch on the Poseidon, AMR and GPSP instruments on Thursday March 30th around 8:30 UTC. Telemetry available on the following pass should enable flowing the first OGDRs around 11:15 UTC, in the middle of cycle 322.

Update #2: The Jason-2 spacecraft entered into safe mode again today (Wednesday, March 22nd) at 13:28:43Z.
After behaving perfectly for 1 week, the gyrometer 1 triggered again a SHM reconfiguration, with the same symptoms as on March 15th.
Jason 2 is currently in BBQ mode, in a safe status. Outside of Gyro 1, all instruments are still OK, and Jason 2 is still able to operate normally on Gyro 2 and Gyro 3.  It has been decided to perform another SHM recovery using gyro 2 and 3.  The actual status of Gyro 1 is currently to be determined : actions will be taken in the coming 2 days in order to investigate it.

Topic: Jason-2 Satellite went into  Safehold Mode on pass 40927.

Date/Time Issued:  March 28, 2017 2002Z

Product(s) or Data Impacted: All Jason-2 OGDRs distributed via DDS and Class users. 

Date/Time of the Initial Impact:  March 15, 2017 1919Z

Date/Time of Expected End:  March 24, 2017 1300Z

Length of the Outage:  TBD

Details/Specifics of Change:  The exact foreseen sequence for restart of the Jason-2 spacecraft is to switch on the Poseidon, AMR and GPSP instruments on Friday March 24th around 10:30 UTC. This means that the first products should be available around 13:00 UTC, after a first orbit of measurements. However, please note that those first products could be impacted by the drag make-up maneuver that needs to be performed around 13:00 UTC.
