SpaceX今天的好消息

 

SpaceX刚刚成功发射并回收了一级火箭。解说之一是位华裔女性，请给她点赞多鼓励哈。这个困难的时候，实在是不容易。

仔细看下面的说明，一级火箭和fairing都是重复使用的。Elon Musk非常重视节约成本，下面的链接里有具体介绍。

“ In an interview given to AviationWeek in May, Musk shared the launch costs of the Falcon 9 and their primary drivers. According to him, once a Falcon 9 first stage has been reused, the marginal cost (the cost for a subsequent launch) for the rocket drops to $15 million. This cost covers areas such as a brand new second stage (which costs roughly $10 million) and booster and fairing recovery, fuel and refurbishment costs for the rest.

The data compilation reveals that this year SpaceX reused seven full fairing sets, for cost savings that could be as high as $42 million. These savings could be lower, such as $35 million if manufacturing efficiencies have managed to bring down fairing costs to $5 million.“

Falcon 9’s first stage booster previously supported the Sentinel-6A mission. One half of Falcon 9’s fairing previously supported four Starlink missions, and the other previously supported a Starlink mission and the Transporter-1 mission.
