摘要

The successful March 17 launch of the European Space Agency (ESA) GOCE Earth observation satellite aboard a Russian Rockot vehicle was a life-saving event for Eurockot Launch Services GmbH, the German-Russian company that sells commercial launches on the converted ICBM. The launch followed the October 2005 failure of the last Eurockot mission for ESA, when a Rockot vehicle sent the Cryosat satellite into the ocean in the Arctic Circle even as launch teams continued to broadcast a launch success to ESA officials. Since then, a series of delays relating to Rockot's Breeze upper stage and other factors had delayed the GOCE satellite so long that mission teams feared they would be forced to change the satellite's orbit, a decision that would have reduced the scientific harvest. In addition, Russian inflation during the same period forced Bremen, Germany-based Eurockot to increase its prices abruptly. A mild solar cycle has permitted GOCE to remain in its intended orbit, and Eurockot hopes other events out of its control will help it solidify its relations with ESA. GOCE is designed to operate in a very low orbit where the residual atmosphere creates drag on the satellite; a more intense solar cycle would have caused more expansion of the atmos- phere, increasing the drag on the satellite and thus forcing ESA to place it into a higher orbit.
