The starboard side International Space Station (ISS) heat rejection subsystem radiator (HRSR)was launched on October 2002, and deployed and serviced in November 2007. A survey ofprevious ISS images and videos verified this radiator was in the normal configuration onAugust 29, 2008. However, on September 1, 2008, a video survey of ISS indicated a face sheethad debonded and peeled up on HRSR S1-3 panel 7 with no apparent source for the damage.This radiator damage consisted of a large section of the face sheet peeled up, sheared face sheetmetal, and debonded from the adjoining face sheet. The face sheet showed considerablewrinkling and evidence of one micrometeoroid orbital debris (MMOD) penetration. The facesheet on the panelâs back side showed a smaller wrinkled area with suspected debonding. Sincebeing discovered, S1-3 panel 7 has showed no observable signs of increasing damage.Additionally, multiple dockings of Soyuz, Progress, and Space Shuttle Orbiter, and vibrationinduced during ISS reboost have resulted in no detectable changes.
