Results from STS-69 Extravehicular Activity Development Flight Test Two

An Extravehicular Activity (EVA) was performed on Space Transportation System 69 (STS-69) to evaluate International Space Station (ISS) assembly and maintenance techniques and ISS EVA tools. The evaluations, collectively called EVA Development Flight Test Two (EDFT-02), were accomplished by operating an EVA task board mounted in the Space Shuttle payload bay and by utilizing ten new and six modified EVA tools.

The EVA task board provided an evaluation platform for ten different ISS assembly and maintenance tasks. The EVA crewmembers, Jim Voss and Mike Gernhardt, assessed their ability to perform these tasks from a fixed-foot restraint, from a robot arm foot restraint, and/or while free-floating. All fourteen primary EVA task board objectives and three of five secondary objectives were completed during the 6 hour and 46 minute EVA.

Approximately seventeen tasks involving the new and modified EVA tools were planned, and all but one major and one minor task were completed.
