MRPO Daily Status Report 06-07-02


GMT Date: 158

Calendar Date: 06/07/02

Increment: 4

Stage: 8A/UF2

Week 25

UF2, aboard STS-111, was launched Thursday and docking occurred today at 11:25 a.m. CDT. Hatch opening will occur approximately two hours later and begin the 8A/UF2 Joint Operations period.

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.

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 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. MAMS and SAMS operated nominally through docking today and were then turned off to conserve energy. 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 RACK 4 (ER4) is powered and supporting payload operations. ER2 was powered down earlier today to conserve electrical energy needed for joint operations. ER1 was powered down shortly after docking. 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.

CGBA is downlinking nominal health and status data. CGBA will be transferred to the STS later today and repowered to continue operations until thirty hours before landing.
CPCG-H is downlinking nominal health and status data. CPCG-H will be transferred to the STS tomorrow.

MAMS operated nominally in the quasi-steady and HiRAP acceleration modes until docking was completed. MAMS was powered down in advance of ER1 being powered down. MAMS data is available on 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 were operating nominally until docking was completed. One SAMS sensor had been powered down and stowed as part of the PCS preparation for quick removal. SAMS was powered down in advance of ER1 being powered down. SAMS data is also available on the acceleration measurement web page.

Near-term Outlook:

Week 25 (6/3-6/9) - On Saturday CPCG will be transferred to the STS and STES-8, StelSys and EXPRESS RACK 3 (ER3), with MEPS mounted in it, will be transferred to the ISS. STES-8 activation and the first EVA, planned for six hours, will occur Sunday.

Week 26 (6/10-6/16) - Much of the crew time will be devoted to transfer operations. MSG will be transferred to the ISS on Monday, 6/10. Two additional EVAs and three reboosts of the ISS altitude will be conducted during this week. Undocking is planned for Saturday, 6/16.
