美国太空探索技术公司3月30日利用翻新的“二手”火箭把一颗商业通信卫星发射上天,这是人类太空史上的第一次。火箭第一级在完成任务后,还再次成功软着陆在大西洋中的一艘船上,距火箭重复使用的最终目标再迈一大步。太空探索技术公司于2015年首次实现“猎鹰9”火箭第一级的陆上回收,2016年4月首次实现海上回收,此后的陆上和海上回收又多次取得成功。
US space exploration technology company launched a commercial communications satellite using the refurbished “second-hand ” rocket on March 30, the first time in human space history. After completing its mission, the first stage of the rocket succeeded once again in a soft landing on a ship in the Atlantic, taking a big step forward from the ultimate goal of re-using the rocket. For the first time in space exploration technology, the company achieved ground-level “Falcon 9” rocket land-based land reclamation in 2015 and the first recycling at sea in April 2016, after which repeated onshore and offshore re-launches have been repeatedly successful.
