Description of Driving Event:
The primary cause of the Magellan mishap was the inadvertent mating of at least two pins of the spacecraft harness connector P2 to connector J3 of battery 1. The mismate of these connectors created an electrical short circuit within the J3 connector that resulted in electrical arcs and additional short circuits that, using the energy stored in the battery, produced damage to battery 1, connector P2, and the battery thermal blanket.
