These are the requested modified versions of the SRCA Spatial Tests. Each uses a -3400 Sector
Rotation (EA Sector viewing of the SRCA) and runs the normal 36 scans per 10% stepping of
the EA Sector Delay. This first portion of the test uses the source Beam Combiner. Afterwards,
the test is repeated with the Neutral Density filter in place of the Beam Combiner and only
utilizing 8 scans per 10% stepping of the EA Sector Delay. The 10 Watt test uses the Spectral
Slit instead of the Along Scan Reticle.
Maneuvers:
Tue, June 20, 2000 – Drag Makeup Maneuver
Wed, June 21, 2000 – MODIS Roll #1 (2000/173/21:50:10 – 21:56:40), roll degree = -18.0044
Wed, June 21, 2000 – MODIS Roll #2 (2000/173/23:28:43 – 23:35:13), roll degree = -17.4518
Wed, June 21, 2000 – MODIS Roll #3 (2000/174/01:07:16 – 01:13:46), roll degree = -16.9070
MODIS Anomalies:
MODIS appears to have stopped controlling on the LWIR Focal Plane. Analysis is underway.
General Instrument Comments:
MODIS is in Science Mode on the A-side with the SVD and NAD open.
MODIS Telemetry Trends:
Telemetry is nominal.
Non-MODIS Significant Events:
Science Data Losses 159/20:00 – 160/20:00: 46362 CADUs of MODIS (equivalent to 31 sec. Day Mode) lost at 160/16:32:33z due to FOT Ops. Error. FOT failed to implement workaround for very high MODIS Buffer amount (86% full). Lockup loss was overwritten before it could be played back.
Additional setbacks from the Ampex tape drive anomalies at White Sands have resulted in numerous data processing backlogs. The following days are still being processed (in the order listed): 147-150, 131-136
