家园 SpaceX 回收第一级有两方面的考量

quora上讨论过这个问题

(1) 重用肯定省钱 (2) 更重要的是大幅提高每年的发射次数

替换(1)Gwynne Shotwell, President of SpaceX, has said on occassion that:

the re-used first stage costs SpaceX “substantially less than half the cost of a new one”.

SpaceX expects a total cost savings of 30% from re-using the first stage.

A 30% cut on the full $60 million price brings the price tag to about $40 million.

替换(2)eusability allows a marked increase in flight rates. Reverse engineered financial models of SpaceX show that to reach a good strong positive cash flow, they need more than the traditional 10–12 launches per year that sized rocket has demonstrated. Reusability should easily double the amount of flights possible from a mere production and logistics standpoint.

With reusability, 20–25 flights a year puts SpaceX into a much more positive cash flow position and thus I believe that this is a very important driver. I believe that the first stage has been identified as one of the bottle necks to flying more often mainly due to its production, transport and attendant infrastructure.

至于您说的“把苹果手机打造成了小资的品味标志,打造成了时尚产品”这个就呵呵了
