MRPO Daily Status Report 3-14-03

GMT Date: 073

Calendar Date: 03/14/03

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 evaluation continues, 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 were reconnected one at a time to attempt isolate the connection
that is causing an MSG circuit breaker to trip. Prior to today, twelve
cables were reconnected and powered with no apparent anomalous results.
Reconnection of the thirteenth cable was performed today with no apparent
anomalous result. The planned fan replacement activity was also performed,
and the new fan appears to be operating nominally. MSG was power cycled
by the MSG Ops Team, and data was collected for further analysis. OCR
msg1all000077 has been submitted to prepare for continuation of troubleshooting
steps on Monday, GMT day 076. This OCR calls for power cycling ESEM 4A
outlet 2 (MLC), ESEM 4B outlet 2, and ESEM 4A outlet 1 (Video drawer)
sequentially, allowing each outlet an hour of operation.

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 occurred every day this week, and
will continue next week.

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.
