MRPO Daily Status Report 3-13-03



GMT Date: 072

Calendar Date: 03/13/03

Increment: 6

Stage: 11A

Week 15

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 is in a trouble-shooting mode.

EXPRESS RACKS 1 and 4 (ER1 & ER4) are powered and supporting payload operations. ER2, ER3 & ER5 are currently powered down.

The MSG circuit breaker problem is continuing to be evaluated and troubleshooting procedures are being implemented carefully. Thirteen sensor cables were disconnected from MSG on day 59, leaving five sensors connected that were verified to cause no problem with MSG powered. The disconnected cables are being reconnected one at a time to isolate the connection that is causing an MSG circuit breaker to trip. Prior to today, eleven cables were reconnected and powered with no apparent anomalous results. Reconnection of an additional cable was performed today with no apparent anomalous result. Tomorrow’s plan will reconnect the last cable, and will also include a planned fan replacement activity.

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 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.

All SAMS sensors in EXPRESS RACKS are operating nominally. The SAMS sensor in the MSG is currently turned-off. 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 15 (3/10-3/16) - Planning for this week was based on approximately 10 hours of crew time for NASA payload operations. The crew will continue preparations for a newly planned EVA during week 17. A ground commanded reboost of the ISS was performed yesterday, and another one is planned for later today. MSG troubleshooting has occurred every day this week, and will continue tomorrow.

Week 16 (3/17-3/23) – Preliminary planning for this week is being based on approximately 22 hours of crew time for NASA payload operations. The flight crew will continue preparations for the newly planned EVA during week 17. Time is being allocated on four days of this week to continue MSG trouble-shooting.
