Floating Potential Probe Design Review

A design review for the Floating Potential Probe (FPP) for STS-97 was held at Glenn Research Center. Representatives from the EVA Project Office, EVA MOD, and EVA Safety supported the EVA portion of the review on October 18, 2000. The EVA Project Office is providing several pieces of hardware to Glenn Research Center for EVA interfaces. Additional GFE hardware needs were identified during the design review. Although plans are proceeding for 4A launch, there are several open actions still being worked. Installing the FPP will require significant EVA efforts, especially due to the antenna installation that is now being planned for the aft side of the Node.

Ranger EVA Technical Interchange Meeting:

EVA Project Office personnel conducted an EVA Technical Interchange Meeting for the Ranger telerobotic flight experiment at the University of Maryland on October 18, 2000. The payload customer provided technical updates on the Ranger payload. (e.g., EVA interfaces, forces, torques, preliminary procedures, etc.) Following the meeting, the Project Manager provided a detailed 1-G walk-around of the high-fidelity Ranger mockup, and then conducted a full (scuba) demonstration of the proposed contingency EVA procedures in the University of Maryland Neutral Buoyancy facility. As a result of this meeting, a plan is now in place to prepare a detailed overview presentation to the EVA CCB in the near future (tentatively, December 2000).

Orlan Suit FMEA Review

EVA Project Office personnel are hosting a 2-week Technical Interchange Meeting (TIM) in Building 7, room 322, with RD&PE Zvezda Orlan spacesuit specialists to finalize Failure Mode Effects Analysis reports, Hazard Reports, and resolve any open issues related to EVA flight hardware readiness to support ISS1. Other topics to be addressed during this TIM include Orlan Liquid Cooling Garment (LCG) repair, Orlan glove repair, Orlan backpack alignment adjustments, review of Joint Airlock and procedure development plan, and the preparations underway to support the Orlan SAFER Critical Design Review (CDR) scheduled in Moscow in January 2001.

STS-92 (3A) EVA’s

All 21of the ISS assembly EVA tasks were successfully completed during the four EVA’s on STS-92 (3A). DTO 689, the SAFER flight demonstration was successfully performed. DTO 675, the Incapacitated Crewmember Translation, was not performed due to insufficient time to complete this DTO on EVA 4. This is not an impact since this DTO can be reschedule to a later flight. Overall, the EVA hardware performed very well. Anomalies were noted on the PGT, EMU, foot restraints and mini-workstation. All anomalies will be addressed to determine the appropriate actions required to resolve them.

2R ISS-1 Flight Readiness Review

The 2R/ISS-1 Flight Readiness Review was conducted on October 19, 2000. There is one scheduled internal EVA to transfer the service module docking cone to the nadir port in preparation for DC1. This requirement may defer out of this increment depending on the potential 3-Progress launch slips. USOS maintenance EVA’s will be defined and trained real-time. The crew has trained to translate down the Russian segment, but specific USOS contingencies have not been trained. The crew is prepared to perform an EVA within 48 hours of an emergency 4A departure to complete EVA-1 tasks to ensure survival of P6 ORU’s. EVA procedures and flight rules continue to be written and will be completed prior to the EVA CoFR2 review. Forward work pertaining to the Orlan hazard reports on CO2 levels and loss of suit pressure will also be completed prior to the EVA CoFR2. The EVA Project Office is ready for 2R launch.
