委星遇到麻烦了

A 3bn yuan (HK3.4bn dollars) satellite China built and launched for Venezuela in late October had encountered some serious operational glitches that Chinese engineers were striving to fix, space-industry sources confirmed yesterday.Details of the malfunction are unknown, and satellite experts are divided on the cause of the issue, as only a handful of self-detecting sensors are on board and the information they pass down is limited.The technicians are anxious, as there is little time left for debate. The Simon Bolivar Satellite -a 5-tonne communications device for radio, television and data transmission -was launched at the Xichang Satellite Launch Centre in Sichuan on October 30. It is being tested and official service is scheduled to begin in February.If the handover is postponed or aborted it would be a blow to the Venezuelan government, which has touted the satellite as proof that Latin American countries can achieve a technological breakthrough without US assistance.







The incident would also hinder China's ambitious and rapidly growing "space diplomacy", aimed at forging political and economic alliances with developing countries -especially oil-or mineral-rich nations in South America and Africa -by admitting them to the space club at an affordable price.But the reputation of China's space programme would suffer the most, industry experts say, as it represented the second failure of another country's satellite within a month.Nigcomsat-1, a communication satellite built and launched for Nigeria last year, failed on November 11 because of a solar-panel breakdown.The failure was announced by the China Great Wall Industry Corporation, the international outlet of the China Aerospace Science and Technology Corporation, which then sacked a senior official in charge of the programme, sending shock waves through the industry.







The nation rarely sacks senior officials for satellite failures, as space missions often encounter problems. The unusually severe punishment came partly because Nigcomsat-1 was China's first exported satellite.The country hoped it could open the international satellite market long dominated by the United States and Russia. The punishment was harsh because a product-quality flaw on the solar panel was "utterly unpreventable", a satellite expert with the Chinese Academy of Space Technology said. "In a space project, we can make two kinds of mistakes.

One is unpreventable because we might be using a new technology, exploring a new environment or be caught by an issue that we had not heard of before. "In this case, you would not expect to be punished," the professor said. "But if you mess up a mission because of management blunders, such as bypassing necessary quality checks, you must take responsibility." The professor said the Nigcomsat-1 satellite had been hastily built to meet a very tight deadline.
