None
MODIS Anomalies:
The TDRS Spare satellite is currently experiencing power system problems and cannot support all user services.
These problems will hopefully be resolved in the next few weeks. In the meantime, the Goddard FOT is relying
on TDE for data transfer. MODIS has consequentially experienced a number of data losses, with more
anticipated in the coming days. Exact times for these losses are:
241/06:07:34-06:07:55
241/08:00:15-08:23:03
242/02:49:49-02:50:56
242/05:05:25-05:07:13
243/01:39:04-01:43:18
General Instrument Comments:
MODIS is in Science Mode, using all A-side components, but cross-strapped to Formatter B, with the blackbody maintained at 290K and the Solar Diffuser Door at the Screened position.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
