MRPO Daily Status Report 3-18-03
GMT Date: 077
Calendar Date: 03/18/03
Increment: 6
Stage: 11A
Week 16
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 and 4 (ER1 & ER4) are powered and supporting payload
operations. ER2, ER3 & ER5 are currently powered down.
Evaluation of the MSG circuit breaker problem continues, and troubleshooting
procedures are being implemented. Thirteen sensor cables were disconnected
from MSG on day 59, leaving five sensors connected that were verified
to cause no problem with MSG powered. All of the disconnected cables
have been reconnected one at a time, to hopefully isolate the troublesome
circuit, but no anomalies have occurred. MSG troubleshooting continued
today and included power cycling ESEM 4A outlet 2 (MLC), ESEM 4B outlet
2, and ESEM 4A outlet 1 (Video drawer) sequentially. Today’s tests
had no apparent anomalous results. Further trouble-shooting is contingent
on the results of an ESA Control Board meeting this Thursday.
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 16 (3/17-3/23) – Planning for this week was based on approximately
22 hours of crew time for NASA payload operations. The crew spent additional
time today completing the replacement of a thermal control loop pump
that failed Sunday. The crew will continue preparations for the recently
defined EVA now being planned for week 19. Further MSG trouble-shooting
is contingent on the results of an ESA Control Board meeting this Thursday.
Week 17 (3/24-3/30) – Preliminary planning for this week is being based
on approximately 2 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 can be allocated for MSG trouble-shooting if
it is needed.
