Firefly confirms launch failure due to the premature shutdown of one engine
Capitalism in space: Firefly this past weekend confirmed that its September 2nd launch failure was caused when one of the Alpha rocket’s first stage engines shut down almost immediately after liftoff.
On Sunday (Sept. 5), the company announced the proximate cause of the failure: One of Alpha’s four first-stage Reaver engines shut down unexpectedly about 15 seconds after liftoff. “The vehicle continued to climb and maintain control for a total of about 145 seconds, whereas nominal first-stage burn duration is about 165 seconds. However, due to missing the thrust of 1 of 4 engines, the climb rate was slow, and the vehicle was challenged to maintain control without the thrust vectoring of engine 2,” Alpha representatives wrote in a Twitter thread on Sunday.
“Alpha was able to compensate at subsonic speeds, but as it moved through transonic and into supersonic flight, where control is most challenging, the three-engine thrust vector control was insufficient and the vehicle tumbled out of control. The range terminated the flight using the explosive Flight Termination System (FTS). The rocket did not explode on its own,” they added.
The engine apparently did not fail or explode, it merely closed its main propellant valves so the engine was no longer being fed fuel. Though they obviously they need to find out why this happened, the nature of the failure is actually encouraging. It suggests a relatively easy fix (with a strong emphasis on the word “relatively”).
The support of my readers through the years has given 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. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
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. Even today NASA and Congress refuse to 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.
