在航天飞机第八次飞行中发射的印度卫星-1B,是美国福特宇航公司西部研制实验室为印度研制的第二颗多用途卫星。去年4月10日由“哥伦比亚号”航天飞机发射的印度卫星-1A,曾由于辐射计遮阳用的伞状太阳帆不能展开以及姿控系统出故障等原因而夭折。同样,印度卫星-1B在8月31日从“挑战者”号航天飞机上发射之后,也出现了太阳电池帆板被卡住而不能完全展开的严重故障。这颗卫星的太阳电池帆板由五块太阳电池板组成,并均装在卫星的同一侧。在它的另一侧安
India Satellite-1B, launched on the Eighth Shuttle Flight, is the second multi-purpose satellite developed by Ford Aerospace Western Development Laboratory for India. Indian satellite-1A, launched by the “Columbia” shuttle on April 10 last year, had died due to the inability of the solar-powered umbrella umbrella to expand and the attitude control system to fail. Similarly, after Indian Satellite-1B was launched from the Challenger space shuttle on 31 August, there was a serious failure that the solar panel was stuck and could not be fully deployed. The satellite solar panel consists of five solar panels and is mounted on the same side of the satellite. On the other side of it
