SpaceX’s reusable first stages and their dramatic impact on the bottom line
This article by Eric Berger at Ars Technica outlining the status of SpaceX’s fleet of reusable first stages contained this incredible fact:
On May 11, 2018, the company launched the first of its new “Block 5” version of its Falcon 9 rocket. This new version of the first stage incorporated all of the company’s previous performance upgrades to the Falcon 9 rocket while also maximizing its reuse. It worked—SpaceX has now flown two different Falcon 9 cores five times, and it may fly a first stage for the sixth time later this summer.
The success of the Block 5 rocket means that SpaceX has had to devote less time and resources to building Falcon 9 first stages. Since May 2018, it has launched 31 times on a Block 5 version of the Falcon 9 rocket—while using just 10 cores. Put another way, reuse has saved SpaceX the cost of 189 Merlin rocket engines, dozens of fuel tanks, and many complex avionics systems. [emphasis mine]
That is a lot of cost savings, which the company is not only using to cut its prices but also to reduce the cost of its Starlink launches. It appears SpaceX wants those launches, as much as possible, to use reused boosters in order to lower the overall cost of getting that internet constellation into orbit. This in turn will make it possible for them to charge less for the service, once they begin offering it.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
