据华盛顿12月14日消息,航天飞机宇航员暂定于1983年12月在空间修理一颗失效的太阳监视卫星,这项大胆的操作将首次论证航天飞机不但能发射卫星,而且还能在轨道上回收甚至修理价值几百万美元的卫星。这颗太阳监视卫星叫太阳峰年卫星,价值6700万美元,是1980年2月发射入轨的,只是由于电子设备故障使七台科学仪器巾的四台失去了效能。太阳峰年卫星目前的轨道高度为545公里,正在缓慢地下降。它的高度是很重要的,因为低于大约458公里时,就可能使卫星难于被空间操作的宇航员控制。目前,太阳峰年卫星
According to Washington, December 14, space shuttle astronauts tentatively scheduled to repair a failed sun surveillance satellite in space in December 1983, this bold operation will demonstrate for the first time that the space shuttle will not only launch satellites but also track Recover and even repair millions of dollars worth of satellites. The Sun-monitoring satellite, the solar peak year satellite, valued at $ 67 million, was launched in February 1980, only to lose the effectiveness of four of the seven scientific instruments and towels due to the failure of electronic equipment. The current solar orbit satellite is 545 kilometers in altitude and is slowly declining. Its height is important because less than about 458 kilometers could make it difficult for satellites to be controlled by space-operated astronauts. At present, the solar peak year satellite
