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. On-orbit recovery efforts were undertaken but were unsuccessful. The Avionics Section was removed and brought back on ISS Flight UF-2.
