太空探索公司首席执行官4月7日发推特表示,他对明年底之前让第二级火箭也能重复使用、从而实现100%的火箭复用“相当有信心”。这表明该公司在实现第一级复用后重新开始重视一度被搁置的第二级复用设想。太空探索公司曾在2011年披露了对“猎鹰”9火箭的两级均加以回收和重复使用的一项方案,但其近几年取得的明显技术进展都仅限于第一级。这是因为第一级着陆回收和重复使用的技术难度相对较小,且在全箭成本中
April 7, CEO of Space Exploration Inc., said he is “quite confident” that he will be able to reuse the second stage rockets by the end of next year to achieve 100% rocket reuse. This shows that the company re-started to re-emphasize the second-level reuse scenario, once shelved, once the first level of reuse was achieved. Space exploration companies disclosed in 2011 a program to recover and re-use both levels of the Falcon 9 rocket, but the obvious technological advances made in recent years have been limited to the first level. This is because the first-level landing recovery and re-use of the technology is relatively difficult, and in full cost of the
