Payloads currently on-board ISS:
BSTC, CGBA, CSLM-2, InSPACE, MAMS, MSG (facility), PFMI, SAMS, STES-10, SUBSA and ZCG.
MAMS, SAMS and STES-10 continue nominal, basically unattended, operations. BSTC, CGBA, CSLM-2, InSpace, PFMI, SUBSA and ZCG are inactive. MSG trouble-shooting is continuing.
EXPRESS RACKS 1 and 4 (ER1 & ER4) are currently powered and supporting payload operations. ER2, ER3 & ER5 are currently powered down.
Evaluation of the MSG circuit breaker problem continues. Over the past 20 days many tests have been systematically conducted in an attempt to isolate the circuit that caused a circuit breaker to trip. No anomalies have occurred during these tests. Plans for follow-on MSG activities next week include a test run with PFMI (no sample heating) that will accomplish a long duration (11 hour) MSG test, and a checkout of the new left AHU fan. If no anomalies occur, PFMI will be removed and InSpace installed to prepare for InSpace payload operations.
InSpace Coil assemblies may need to be inspected again prior to beginning test operations if it becomes feasible to install the payload in the MSG.
MAMS is currently operating nominally in the quasi-steady mode. HiRAP is currently inactive. MAMS data is available on the acceleration measurement web page.
PFMI hardware removal from the MSG is contingent upon success of MSG trouble-shooting.
SAMS data flow from all sensors in EXPRESS Racks was recovered Wednesday following the unplanned power down of ER1 and ER4. SAMS ER1 Z-panel sensor (121f04) stopped transmitting data at approximately GMT 079 (20-Mar) 2003/19:36. Commands were sent to establish communication, and sensor data stream was recovered at GMT 080 2003/16:50. The SAMS sensor in MSG is turned-off. SAMS data is also available on the acceleration measurement web page.
STES-10 health and status data has been nominal since it was re-powered yesterday following an unplanned power down of ER4. STES-10 is configured with diffusion-controlled chambers that require no crew operation activities.
Week 16 (3/17-3/23) – Planning for this week was based on approximately 22 hours of crew time for NASA payload operations. The crew is continuing to spend considerable time correcting a thermal control loop problem that occurred last Sunday. All PSR/SPD payload activities planned for this week have been accomplished.
Week 17 (3/24-3/30) - Preliminary planning for this week is being based on approximately 2 hours of crew time for NASA payload operations. The crew will continue preparations for the recently defined EVA now being planned for week 19. Time can be allocated for MSG trouble-shooting if it is needed.
