摘要

The Indian Space Research Organisation (ISRO) is blaming the premature demise of its Chandrayaan-1 lunar orbiter on overheating of the spacecraft's onboard electronics.rnISRO spokesman S. Satish said agency scientists planning the mission underestimated the temperatures Chandrayaan-1 would encounter at its initial 100-kilometer mapping orbit.rnAs a result, Chandrayaan-1's thermal protection systems were designed to keep spacecraft electronics running cool amid in-orbit temperatures expected to top out around 75 degrees Celsius. When the thermal environment proved hotter, problems ensued. While everything points to overheating as the most likely grounds for the mission failure, an expert committee will conduct a thorough study to pinpoint the exact cause, Satish said. He declined to say who will head the enquiry, whether the committee will include experts from outside ISRO, or when its report would be available.
