Popis: On October 25, 2004 ADEOS-2 (Advanced Earth Observing Satellite-2; Midori-2) ceased supplying observational data owing to a catastrophic power failure. FTA (Fault Tree Analysis) suggested that a rupture or short circuit of the power harness between the PDL (Solar Array Paddle Subsystem) and the electric power subsystem was the most likely cause. Material tests were conducted on the harness to elucidate the failure mechanism. High-temperature thermal cycling was seen to lead to anomalous expansion and contraction of the harness cable insulators. This phenomenon resulted in abrasion and fatigue of these materials.
