摘要

Europe's GOCE gravity-measuring satellite, which began operations late last year, has lost the use of one of its two on-board computers in what program managers said is a rare, and still-unexplained, failure of a well-proven computer chip.rnThey said that given the flight history of the component, they are not overly concerned that the backup system, which uses the same chip, will also fail.rn"This is the first time this has happened with this chip so far as we can tell," said Reiner Rummel, chairman of the Gravity and steady-state Ocean Circulation Explorer (GOCE) satellite's advisory group. The satellite was launched in March 2009 on a two-year mission.
