SpaceX今天的好消息

 

SpaceX剛剛成功發射並回收了一級火箭。解說之一是位華裔女性，請給她點讚多鼓勵哈。這個困難的時候，實在是不容易。

仔細看下麵的說明，一級火箭和fairing都是重複使用的。Elon Musk非常重視節約成本，下麵的鏈接裏有具體介紹。

“ 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.
