[note 1]
The contact for these particular dumps were MA (multiple array) contacts. The FOT has had "off and on" experience with the communications over MA contacts. An attempt was made to perform multiple partition dumps ('bb_output' and 'cp_mode'). Roughly half of the dump partitions were not captured for those dumps. The "MOD_MEM_HALT" procedure was run to clear the MODIS Memory Dump Buffers after the unsuccessful dump attempts. The command and return data streams for MA contacts have much greater latency than SA (single array) contacts. This extra latency causes timing problems with the memory dump procedure. Future MODIS Memory Dumps on Terra will avoid using MA contacts.

This Week’s Scheduled MODIS Activities Not Completed:

Tuesday, July 29, 2003

Contingency for Terra Inclination Maneuver; the commands in this activity are inhibited.
2003/210 14:56:13-14:57:54 MOD_CLOSE_NAD_SVD.1 (101 seconds prior to S/C day, orbit 19211)

Thursday, July 31, 2003

Contingency for Terra Inclination Maneuver; the commands in this activity are inhibited.
2003/212 16:22:54-16:24:35 MOD_CLOSE_NAD_SVD.1 (101 seconds prior to S/C day, orbit 19241)

Upcoming MODIS Events:

August calibrations will include weekly SDSM, an SRCA Full Radiometric, semi-monthly SRCA 10 Watt radiometric, bi-monthly PV Ecal, and a lunar roll calibration.

Tuesday, August 5, 2003

2003/217 20:01:11-20:09:59 ATC MOD_OA16_SDSM_SCRN_NO_DOOR_A.4 OA16: SD/SDSM screened side A, no door movement.

Wednesday, August 6, 2003

Contingency for Terra Inclination Maneuver; the commands in this activity are inhibited.
2003/218 15:46:15-15:47:56 MOD_CLOSE_NAD_SVD.1 (101 seconds prior to S/C day, orbit 19329)

Maneuvers:

The next MODIS lunar calibration will be on August 16, 2003 (DOY 2003/228). Data collection will be from 19:24:54 -19:31:24 GMT, and the roll angle will be -5.1828 degrees.

An additional Terra inclination maneuver is planned for Wednesday, August 6, 2003.

MODIS Anomalies:

None

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.
