MRPO Daily Status Report 3-24-03



GMT Date: 083

Calendar Date: 03/24/03

Increment: 6

Stage: 11A

Week 17

Payloads currently on-board ISS:
BSTC, CGBA, CSLM-2, InSPACE, MAMS, MSG (facility), PFMI, SAMS, STES-10, SUBSA and ZCG.

Status:
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, 2 and 4 (ER1, ER2 & ER4) are currently powered and supporting payload operations. ER3 & ER5 are currently powered down.

Evaluation of the MSG circuit breaker problem continues. 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. Today’s MSG activities will 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 Air Handling Unit fan. If no anomalies occur, PFMI will be removed and InSpace installed Thursday to prepare for InSpace payload operations.

InSpace Coil assemblies will be inspected tomorrow if today’s MSG test is successful.
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 will be removed from MSG Thursday if today’s MSG/PFMI test is successful.

SAMS data flow from all sensors in EXPRESS Racks and MSG is nominal. The SAMS sensor in MSG was turned-on today as part of the MSG/PFMI test. SAMS data is also available on the acceleration measurement web page.

STES-10 health and status data is nominal. STES-10 is configured with diffusion-controlled chambers that require no crew operation activities.

Near-term Outlook:

Week 17 (3/24-3/30) - Planning for this week was based on approximately 10 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 is allocated for MSG trouble-shooting, removal of PFMI and installation of InSpace for operation.

Week 18 (3/31-4/6) - Preliminary planning for this week is being based on approximately 14 hours of crew time for NASA payload operations. The crew will continue preparations for the recently defined EVA now being planned for week 19. InSpace operations were not included this week, but if InSpace is installed in MSG as appears possible, every effort will be made to schedule one or more runs.
