MRPO Daily Status Report 06-05-02


GMT Date: 156

Calendar Date: 06/05/02

Increment: 4

Stage: 8A

Week 25

The launch of UF2, aboard STS-111, has finally been successful lifting off at approximately 4:22 p.m. CDT today. Docking will take place on Friday.

MRPO payloads launched on UF2 are: ADVASC, InSPACE, MEPS, MSG (a full rack of equipment), PFMI, StelSys, STES-8, SUBSA, ZCG samples. Also EXPRESS RACK 3 (ER3), with MEPS mounted in it, will be delivered on STS-111. Appropriate steps have been taken to reload and/or replenish sample in payloads that required it due to the launch delay.

MRPO payloads to be returned on STS-111 are: BTR, CGBA, CPCG-H, PCG-EGN, PCS, and ZCG samples.

Payloads currently on-board ISS: BSTC, CGBA, CPCG-H, MAMS, PCG-EGN, PCS, SAMS and ZCG

Status:
MRPO payloads CGBA, CPCG-H, MAMS, SAMS and PCG-EGN, continue nominal unattended operations. All BSTC equipment is currently inactive. BTR, the biotech refrigerator, which had one of its cooling elements inoperative, will be returned to the ground on UF2 for anomaly analysis. PCG-EGN is a passive payload and will operate undisturbed until it is returned on UF-2. PCS failed on day 056 and will be returned on UF-2 for analysis. ZCG operations have been completed and the samples have been removed from the furnace for return on UF2.

EXPRESS RACKS 1, 2 & 4 (ER1, ER2 & ER4) are powered and supporting payload operations. EXPRESS RACK 5 (ER5) has been checked-out, configured as a back-up to ER4, and powered down. MAMS and part of SAMS are located in ER1. PCS, part of SAMS and ZCG are located in ER2. ER4 houses the payloads requiring continuous power such as CGBA, CPCG-H, and part of SAMS.

During Joint Ops, requirements for additional power by the ISS will necessitate the powering down of ER2 and a good part of time ER1. ER4 will remain powered.

CGBA is downlinking nominal health and status data.

CPCG-H is downlinking nominal health and status data

MAMS is operating nominally in the quasi-steady acceleration mode. MAMS HiRAP sensor is currently inactive. MAMS data is being posted to the acceleration measurement web page.

The PCS flight system is inoperable and the hardware has been prepared for quick removal and return on UF-2. The failure will result in a 5%-15% loss of science.

Four SAMS sensors are operating nominally. One SAMS sensor has been powered down and stowed as part of the PCS preparation for quick removal. SAMS data is being posted to the acceleration measurement web page.

Near-term Outlook:

Week 25 (6/3-6/9) - Launch delays have required re-planning for the current week. The 8A/UF2 joint operations period will not begin earlier than Friday 6/7.
