Payloads currently on-board ISS:
BSTC, CGBA, CSLM-2, InSPACE, MAMS, MSG (facility), PFMI, SAMS, STES-10, SUBSA and ZCG.
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.
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. The disconnected cables have been reconnected one at a time to isolate the connection that is causing an MSG circuit breaker to trip. Reconnection of the thirteenth cable was performed Friday with no apparent anomalous result. The planned fan replacement activity was also performed, and the new fan appears to be operating nominally. Continuation of MSG troubleshooting tomorrow will include 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.
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 is spending today replacing a thermal control loop pump that failed yesterday. The flight crew will continue preparations for the recently defined EVA now being planned for week 18. Time is being allocated on several days of this week to continue MSG trouble-shooting.
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 primary focus during this week will be preparation for the EVA during week 18.
