Hubble Telescope Repair哈勃望远镜维修
The optical problems of the Hubble Space Telescope were corrected by a shuttle mission in December 1993. This put it back in service in time to image the impacts on Jupiter by comet Shoemaker-Levy 9. In early 1997 there was a second servicing mission. 哈勃太空望远镜的光学问题于1993年12月通过航天飞机任务得到了修正。这使它及时能够拍摄到彗星施瓦茨-莱维9号对木星的影响。1997年初又进行了一次第二次维护任务。
