MRPO Daily Status Report 2-24-03


GMT Date: 055

Calendar Date: 02/24/03

Increment: 6

Stage: 11A

Week 13

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 initial trouble-shooting procedures have been proposed. The nature of the MSG failure is requiring that very careful trouble-shooting approaches be used to assure further damage is not caused by the tests performed to isolate the problem. MSG trouble-shooting procedures are expected to begin this week.

InSpace Coil assemblies have been confirmed to be ready to begin test operations when it is 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 13 (2/24-3/2) - Planning for this week was based on approximately 14 hours of crew time for NASA payload operations. Today is a crew holiday. Time is allocated for MSG trouble-shooting several times during this week.
