STS-97 (Endeavour)

 2000-078A


The STS-97 flight took the P6 truss to the International Space Station. The P6 truss was easily latched to Z1 as EVA astronauts Tanner and Noriega guided it in, but during deploy of the solar arrays, a software problem delayed the effort. Solar wing 2B (the starboard wing) and 4B (the port wing) were to be deployed. 2B was deployed and tensioning wires came loose, so the port wing deploy was delayed and done slowly the next day.

On the second EVA P6 was wired up to the station. It was decided to add a new task to EVA-3: repairing 2B's tensioning wires. This was done quickly, and the original taks of installing the Floating Potential Probe experiment was done. This measures whether the PCU's are successful in bleeding off excess charge from the arrays; there was some fear that EVA astronauts might be hit by a bolt of lightning from the arrays. The FPPE was installed on top of P6 between the SAWs. The thermal cover of the FPPE has an evergreen drawn on it as a nod to the tradition of topping out a tall terrestrial construction project.

STS-97 uses RMS 303. Launch mass 120740 kg; landing mass 89756 kg. Mass at MECO 116264 kg, after OMS-2 114777 kg. A new GPS SIGI DTO experiment was carried. 641 kg of internal transfer, possibly including the 40 kg FPPE (of which 23 kg was the actual removable experiment).
