The preparatory activities for the launch of ESA's GOCE satellite from the Plesetsk cosmodrome in northern Russia was halted during the afternoon of September 7th by Eurockot. The suspension of activities was due to an anomaly identified in one of the guidance and navigation subsystem units within the Breeze KM launch vehicle's upper stage. The unit will now need to be replaced, which will require the launcher's upper composite to be de-mated and transported from the launch pad to the integration room. Once in the clean room, the protective fairing that shelters the satellite will be opened and the spacecraft and its adaptor system will be dismounted in order to allow access to the Breeze KM equipment to be replaced. Taking into account the duration of the refurbishment operations and the re-mating of the adaptor system, satellite and fairing, the launch has been currently rescheduled for October 5th at 16:21 CEST. The satellite and its mission will not be affected by this launch delay, according to the European Space Agency.
