MRPO Daily Status Report 3-12-03

Status Report From: Microgravity Research Program Office
Posted: Wednesday, March 12, 2003


GMT Date: 071

Calendar Date: 03/12/03

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, nine cables were reconnected and powered with no anomalous results. Two additional cables were reconnected today (total of 16 sensors connected) with no anomalous results. Reconnection of an additional cable is planned tomorrow.

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. Two ground commanded reboosts of the ISS to a higher orbit are planned, one later today and one tomorrow. Time is allocated on five days of this week to continue MSG trouble-shooting.

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.
