The European Space Agency (ESA) is reporting that the Russian authorities responsible for the Rockot launcher designated to boost the GOCE Earth Explorer satellite into orbit have now completed the investigation of the failure in the guidance and navigation system of the launcher's Upper Stage (Breeze KM). The anomaly was discovered during the spacecraft's launch preparation tests on September 7th, 2008, in Plesetsk. This subsequently led to the postponement of the launch. The cause of the anomaly in the guidance and navigation system has been identified and reproduced. The necessary hardware changes will require a minimum of two months of additional work by the manufacturer. As a consequence, the launch of GOCE cannot take place any earlier than February 2009. The exact launch date will be decided at a later stage after corrective measures have been fully implemented and validated.
