北京时间2017年3月31日早上,美国太空探索技术公司(Space X)的“猎鹰9”火箭点火升空,将卢森堡卫星通讯企业的SES-10卫星送入地球同步轨道。与以往不同的是,这次发射的是一枚“二手火箭”。而且他们又把这枚火箭收了回来,准备修修补补以后接着用。Space X曾宣称,火箭重复使用1次,发射成本能降低30%;使用10次能把成本降低80%。据此,有人将这次“二手火箭”的成功发射誉为“改写航天史的创举”。
Beijing March 31, 2017 Morning, Space X’s Falcon 9 rocket was launched and the satellite SES-10 of the Luxembourg satellite communications company was launched into geosynchronous orbit. Different from the past, this launch is a “second-hand rocket.” And they took the rockets back again, ready to repair later use. Space X has claimed that a rocket re-use 1 time, launch costs can be reduced by 30%; use 10 times to reduce costs by 80%. Accordingly, some people have labeled this successful launching of “Used Rockets” as “a pioneering work that rewrites the history of spaceflight.”
