Due to the recent PWA failure on the EOS Terra spacecraft, MODIS has a reduced on-board memory allocation. Initial efforts reduced the data rate of day mode data (reflective solar band measurements) near the poles in a uniform manner. In an attempt to provide near-global two-day coverage, an alternating schedule was implemented starting November 8, 2020 (2020/313).

The Terra spacecraft experienced a PWA (printed-wire assembly) failure on Monday, October 5, 2020. The incident was noted by the Terra flight operations team at 15:21:12z.  As part of the recovery, science recording was disabled on October 6 (2020/280) at 03:32:56z to handle the moving of the supersets and was re-enabled at 03:41:56z. 

December 18, 2019 marked the 20 year anniversary of Terra launch. The MODIS instrument on-board the Terra spacecraft has well surpassed its design lifetime, but continues to acquire valuable science data. The images above are the MODIS first light (left) and the same region viewed earlier this year (right) show the continued consistency of the instrument over 20 years of successful operation.
