This Week's Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

Notes for Yaw Maneuvers:

The yaw maneuvers use sector rotation (to -3400 counts). During this time, the formatter is set to DAY rate. In order to balance the MODIS data output, and equal amount of NIGHT rate data will be collected during what would normally be DAY rate.

Current Ascent Plan (as of June 14, 2002):

  • Ascent 1 on May 13, 2002 at 12:14 for 335 seconds - Successful
  • Ascent 2 on June 5th, 2002 at 15:13 for 962 seconds - Successful
  • Ascent 3 on June 8th, 2002 at 13:02 for 760 second - Successful
  • Ascent 4 on June 10th, 2002 at 14:20 for 945 seconds - Successful
  • Ascent 5 on June 13th, 2002 at 13:50 for 750 seconds - Successful
  • Burn #6: June 17th, 2002 at 16:00:00, 650 second duration

MODIS Anomalies:

A total of 32 pairs of 5D/77 CP event messages have been received since DOY 144 when MODIS turned ON for the second time. Including the first period when MODIS was powered, 55 pairs of events have been received. The last event was seen on DOY 158 at 09:16:16. A single 5D message has been recorded since transitioning to Science Mode, but there was no accompanying 77 event message. Separately, a single CP event message 77 was received without a 5D.

Six single 5D event messages were observed throughout the day on Friday, June 14th. Each of these events occurred within 7 to 10 seconds after a sector rotation (to -3400) command for the SD/SDSM calibrations. An event did not occur for every calibration, and some calibrations resulted in two 5D events.

General Instrument Comments:

MODIS is currently in B-Side Science Mode (Power Supply 2, Control Processor B) with the Space View Door at its Open Position. The instrument has reached its nominal operating temperature. The blackbody calibrator has been powered on and set to 285K at one-third heater duty cycle.

MODIS Telemetry Trends:

MODIS started controlling at 83K (with the SMIR focal plane heater) on Sunday, June 9th at 18:26 GMT. The blackbody stabilized at 285K at approximately 18:40 GMT June 11th.
