过去,在将卫星或飞船送入太空后,火箭会像石头一样落地后报废。美国两家私人公司完成了足以载入史册的火箭飞行。“猎鹰9号”运载火箭在将11颗通讯卫星送入预定轨道的同时,成功实现火箭第一级的软着陆和高精度回收。这次软着陆回收意味着火箭能像飞机一样重复使用,将显著降低太空飞行的成本。 In the past, after the satellites or spacecraft were put into space, the rockets would be scrapped after falling like rocks. Two privately owned U.S. companies completed a rocket flight that could be loaded with history. “Falcon 9” launch vehicle succeeded in achieving the first level of soft landing and high-precision recovery of rocket vehicles while sending 11 communications satellites to a scheduled orbit. The soft landing recovery means the rocket can be used like an airplane and will significantly reduce the cost of space flight.
