美国航天飞机从发射入轨到与国际空间站完美对接,整个过程大致可分为地面导引、自动寻的、最后逼近、对接合拢4个阶段。美国“发现”号航天飞机用了2天时间才和国际空间站完成对接。
The launch of the U.S. spacecraft from launch to the perfect docking with the International Space Station can be roughly divided into four phases: ground guidance, automatic search, final approach and docking. The United States “Discovery ” space shuttle took two days to complete docking with the International Space Station.
