Falcon 9 to be modified
The competition heats up: SpaceX is modifying its Falcon 9 rocket based on engine tests it performed on the December 22 returned first stage.
SpaceX will be making modifications to its Falcon 9 rocket based on what the company learned from re-igniting the engines on the vehicle it landed. That’s according to SpaceX president Gwynne Shotwell, who spoke about the state of the company today at the Commercial Space Transportation Conference in Wasington, DC. Shotwell didn’t specify what those modifications will be, but said the changes will make the vehicle “even more robust” for its ascent into space.
This report helps explain why SpaceX has pushed back all planned launches of the upgraded Falcon 9 rocket. Their tests of the returned first stage revealed issues that they think are important enough to be addressed before another rocket is launched, and they are proceeding to deal with those issues.
It also illustrates an enormous advantage they have over every other rocket company that has ever existed in the past. They, unlike all past rocket companies, actually have a used first stage that they can study to see the real consequences of launch and landing. All previous estimates of those consequences were only based on computer models and speculation.

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.

Hmm. It’s known that kerosene engines leave coking after firing. So maybe it’s to reduce the amount of coking to allow reuse.

“It also illustrates an enormous advantage they have over every other rocket company that has ever existed in the past. They, unlike all past rocket companies, actually have a used first stage that they can study to see the real consequences of launch and landing.”
It also illustrates how rapidly SpaceX can respond to unexpected issues on the run. My guess is that they will have a fix in place in short order, which illustrates an additional advantage over legacy companies.
