Lance-MODIS Terra spacecraft in safe mode (fixed)
|Last Updated||2016-03-01 17:40:00|
Terra MODIS was transitioned to science mode on Feb 24, 2016 (day 055) after being in safe mode since Feb 18, 2016 (day 049). Though the data is currently being acquired and processed at MODAPS and NRT, users are advised to exercise caution in using the products in any application. Products from period 055 - 058 might have been severely degraded due to abnormal operating temperature for the SWIR and LWIR FPA and hence products may not be usable in any application. Though the focal plane temperatures have reached the stable operating value as of day 060 some products may still have been impacted by the increased noise in some of the detectors in the thermal bands. Users are requested to exercise caution in using the products until further notice.
Terra spacecraft remained in safe hold throughout the weekend allowing time for the Flight Operations Team to determine cause of entry into safe hold, develop recovery procedures, test against simulator and present to Anomaly Review Board plans for recovery. Today, February 22, 2016, the recovery procedures were approved. The Flight Operation Team was successful in restoring operations to the Spacecraft Computer. Instrument recovery activities will start tomorrow and likely take multiple days.2016-02-19T13:40:00Z
The Terra spacecraft entered safe mode at 2016-02-18 1433z. Spacecraft is currently in a stable configuration however there is no science data being collected. Recovery is likely to take multiple days.
L0 data was received and processed up to about 14:30z.
