Lessons Learned - Allow for More Flexibility of ISS Protocols During Troubleshooting Phases
Year: 2002
Abstract: Description of Driving Event:
The Physics of Colloids in Space (PCS) experiment was launched on ISS Flight 6A in April 2001 was activated in EXPRESS Rack 2 on May 31, 2001, and was successfully operated on the International Space Station (ISS) until February 24, 2002. On February 24, 2002, at the onset of a scheduled operational run on ISS, the PCS flight system computer (within the PCS Avionics Section) failed to boot up. Once the Expedition 4 crew member had unsuccessfully executed the procedures on March 20, 2002, there was no discussion held with him to ask his opinion on the procedure and if he felt it worthwhile to retry the procedure. Also, the decision by the Payload Operations Director to terminate the recovery procedures and tear down the setup came quickly, with very little room for the PD to appeal. The Project found during post-flight face-to-face discussions with the astronaut that he would have been willing to retry the procedures when he had time later.
