MRPO Daily Status Report 06-25-02


GMT Date: 176

Calendar Date: 06/25/02

Increment: 5

Stage: UF2

Week 3

Progress 7 undocked from the ISS today at approximately 3:23 a.m.CDT. Re-entry into the earth's atmosphere occurred approximately four hours later.

Payloads currently on-board ISS: ADVASC, BSTC, InSPACE, MAMS, MEPS, MSG, PFMI, SAMS, StelSys, STES-8, SUBSA and ZCG. InSpace will not operate during this increment.

Status:
MRPO payloads ADVASC, MAMS, SAMS and STES 8 continue nominal unattended operations. BSTC and StelSys operations have been completed successfully. BSTC has been deactivated and the StelSys samples are stored in the ARTIC-1 refrigerator/freezer and are to be returned on 9A.

EXPRESS RACKS 1, 2 and 4 (ER1, ER2 & ER4) are powered and supporting payload operations. ER2 was repowered yesterday. ER3 is installed in the US Lab and will be checked out later. ER5 was checked out during Increment 4 and powered down.

The Medium Rate Communication Outage Recorder (MCOR) is experiencing occasional over-temperature conditions requiring it to be turned-off. When MCOR is turned-off, payload data is lost during loss of signal periods. JSC is assessing possible corrective actions to improve MCOR operations.

ADVASC is downlinking nominal health and status data and plants are visible. Historical photographs of the payload were taken today. Gas and condensate sampling are planned for Thursday.

MAMS is operating nominally in the quasi-steady mode. HiRAP is currently turned-off. MAMS data is available on the acceleration measurement web page.

MEPS is stowed in ER3. It will be transferred to ER1 during this week and initial operations are scheduled for week 6.

MSG checkout will be initiated in week 4. Based on observations of the MSG ground engineering unit, the crew will inspect, and possibly replace, the MSG video drawer umbilical hook tomorrow.

PFMI is stowed in the US Lab and is scheduled to operate in the MSG late in this increment.

SAMS equipment in all racks is operating nominally. SAMS data is also being posted to the acceleration measurement web page.

STES-8, with all six growth chambers activated, is downlinking nominal health and status data.

SUBSA is stowed in the US Lab and will be operated in the MSG following completion of MSG checkout.

ZCG sample autoclaves were placed in the ZCG furnace yesterday and the primary and back-up computer processing units were exercised. The primary unit checked-out fine but the back-up unit did not establish communications. Trouble-shooting is being planned in advance of beginning furnace operations on Thursday.

Near-term Outlook:

Week 3 (6/24-6/30) ) -Planning for this week was based on approximately 21 hours of crew time availability for NASA payload operations. Progress 8 will be launched and docked with the ISS during this week. ADVASC sampling will be conducted. MEPS will be transferred to ER1 and MSG checkout will begin.

Week 4 (7/1-7/7) - Preliminary planning is being based on approximately 6.5 hours of cre¤ăĆdme availability for NASA payload operations. The crew will spend significant time transferring materials from Progress 8. July 4 will be a crew off-duty day. SUBSA set-up and historical photographs are planned. Historical photographs of SAMS and STES-8 are also planned.
