SpaceX cancels launch after reviewing static fire test data
After a review of the test data produced during its standard dress rehearsal countdown and static fire prior to launch, SpaceX decided to cancel a Falcon 9 launch yesterday, carrying 52 Starlink satellites.
The first stage booster had previously launched 10 times, though it is not clear if this is the cause of the delay.
It’s not the first time SpaceX has delayed a launch indefinitely after a static fire test, but it is the first time in years. SpaceX semi-regularly stands down from launch attempts to conduct inspections or complete minor repairs or component replacements when data is amiss or contradictory, but those plans tend to mention the next launch target. This time, even SpaceX’s website has been scrubbed to say that “a new target launch date [will be announced] once confirmed.”
The last time a prelaunch static fire was explicitly blamed for a launch delay was in August 2019, when SpaceX fired up a Falcon 9 rocket ahead of its Amos-17 launch, didn’t like what it saw, decided to replace a valve on the booster, and then conducted a second static fire test to clear the rocket to launch. It’s possible that Starlink 2-4’s sequence of events will end up being similar.

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.

Sorry, Elon…
Shows that these static fires are still a good idea.
Some time not long ago, the question was posed if they will continue these, or not.
I think this answers the question. They are a needed step.
Also, I think it reflects how familiar the SpaceX engineers are with the engines and the performance data and shows that there is no “go fever” pushed from the top.
