Firefly launch fails
In its first launch attempt in 2025, Firefly’s Alpha rocket had a problem shortly after the first stage separated from the upper stage and the upper stage’s engines began firing. The upper stage began swivel somewhat though it appeared to stablize after a few seconds.
Subsequent reports confirmed that the stage failed to reach orbit.
The launch of the FLTA0006 mission appeared to go as planned until stage separation about 2 minutes and 35 seconds after liftoff. A cloud suddenly formed between the two stages, and video showed what appeared to be debris falling away as the upper stage continued its ascent.
A camera on the upper stage also showed debris falling away from it seconds after separation. The nozzle for the single Lightning engine in the upper stage appeared to be seriously damaged, if not missing entirely.
In a statement four and a half hours after launch, Firefly confirmed that the upper stage and its payload failed to reach orbit because of the stage separation issue. “The rocket then experienced a mishap between stage separation and second stage ignition that led to the loss of the Lightning engine nozzle extension, substantially reducing the engine’s thrust,” the company stated.
Alpha has now launched a total of six times, but only two of those launches were completely successful. Two of the other launches got their payloads into orbit, but not at the proper positions. In all the failures but one, the problems were with the upper stage. Today’s failure is another example of this.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID 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. Every one of those 2020 conclusions has turned out right.
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.

I see Firefly pivoting from launch and working more on cis-lunar projects. They know how to get to the moon.
I wish more NewSpacers would look at parallel staging, stage-and-a-half concepts, etc.
Truax lamented how upper stages cost as much if not more than first stages..
A first stage has people about to look things over– all upper, in-line stages fire alone–no help.
I remember reading about mini- and micro-shuttles that looked like scaled down STS stacks.
ALS was to use parallel staging–which means all engines are at ground (pad) level for inspection.
A stage-and-a-half schema means you burn one set of engines pretty much all the way up.
Small, reusable external tanks with a TPS might be recovered even as fairings are.
