On August 5, 2017, the Terra spacecraft completed a deep space pitch maneuver. During this maneuver, the moon was visible through the MODIS earth-view port. Details are included below. MODIS was in Day Collection rate during the maneuver, instead of nominal Night Collection. MODIS telemetry and gain parameters stabilized by 2017/218 14:20 (GMT).
Start: 2017/217 23:15:45
Moon Center: 2017/217 23:29:54
End: 2017/217 23:51:39
Terra MODIS experienced a data corruption issue stemming from the Science Formatter Equipment (SFE) Assembly. Terra FOT cycled the formatter and MODIS science data acquisition resumed as expected. Data is unavailable for day 2017/114 (04/25/2017) from 03:44:03 - 19:44:58. Similar anomalies have occurred previously.

In support of the upcoming Collection 6.1 reprocess, MCST applied a correction for the electronic crosstalk (Xtalk) contamination in the Terra MODIS photovoltaic (PV) long-wave infrared (LWIR) bands 27-30. Using scheduled lunar observations, the correction coefficients are derived and applied to the on-board calibrator (OBC) data and Earth-view (EV) data to correct the L1B calibrated radiance for bands 27-30. This results in a significant reduction in the image striping and radiometric biases in the L1B data.
MODIS Collection 5 data products will no longer be produced after the end of March 2017. Collection 6 data products were introduced in 2012 and are available for the entire mission record for both Terra and Aqua MODIS.
