During a static fire engine test yesterday in preparation for launch, the rocket startup Firefly lost the first stage when an explosion occurred at what appeared to be the base of the rocket. From the company’s update:

During testing at Firefly’s facility in Briggs, Texas, the first stage of Firefly’s Alpha Flight 7 rocket experienced an event that resulted in a loss of the stage. Proper safety protocols were followed, and all personnel are safe. The company is assessing the impact to its stage test stand, and no other facilities were impacted.

Video of the explosion can be seen here.

This incident will obviously delay the next launch, which had only just been scheduled following the completion of the company’s investigation into its launch failure in April. This explosion also suggests there remain serious issues with the Alpha rocket, which has only had two full successes in six launch attempts.

At the same time, with the successful soft landing of its Blue Ghost lander on the Moon earlier this year, Firefly has demonstrated its engineering can be sound and robust. It just appears that a lot more work needs to be done to get Alpha into shape.

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.

In announcing its plans to begin launches from both Wallops Island in Virginia and Esrange in Sweden in 2026, Firefly has also said it is planning five launches from Vandenberg in 2025.

The company is also building a launchpad at Cape Canaveral, so if these plans reach fruition it will eventually have four different launch sites. One issue for all these sites remains red tape. For example:

[Firefly VP Adam] Oakes said Firefly is continuing to work on regulatory issues for launches from Esrange. “The regulatory piece can really put you back if you want to let it,” he said. “We have a lot of paperwork in place. We’re not quite there on everything but things are moving in the right direction.”

One serious problem for Esrange is its interior location in Sweden. Any orbital launch will have to cross land, with most crossing significant territory of other countries. While the site has been used for decades for suborbital test launches, no orbital launches have ever taken off from there, and getting clearance will not be easy for orbital rockets to cross either Norway, Finland, or Russia. And unless the lower stages are reusable they will have to crash inside those territories, or inside Sweden itself.

Firefly yesterday scrubbed its second attempt to launch eight cubesats for NASA and others using its Alpha rocket, postponing the next launch attempt in order to the review the ground system issue that caused the two launch aborts on the first launch attempt on July 1, 2024.

In a social media post, the company stated that it’s standing down “to give the team more time to evaluate data and test systems from the first attempt. … We will work closely with the range and our NASA customer to determine the next launch window,” Firefly wrote on X.

This would have been Alpha’s fifth orbital launch. No new launch date has been announced, though it is expected to occur before the end of this month.

Though it has only flown a few times (with some of those launches failures or only partially successful), Firefly’s Alpha rocket has a robust launch manifest, with its biggest contract with Lockheed Martin for 25 launches. It has signed deals to launch from Wallops Island and Vandenberg, as well as the Esrange spaceport in Sweden. And it also has a contract to build the first stage for Northrop Grumman’s Antares rocket.

According to the rocket startup Firefly, a software issue prevented the engine on the upper stage of its Alpha rocket from firing its final burn, leaving a Lockheed Martin satellite in the wrong orbit.

In a Feb. 20 statement, Firefly said an error with the guidance, navigation and control (GNC) software for the upper stage of the Alpha on the company’s “Fly the Lightning” mission Dec. 22 kept the upper stage from firing as planned to circularize its orbit. That left the upper stage and its payload, a Lockheed Martin technology demonstration satellite, in an orbit with a low perigee.

The investigation, which included the company’s own mishap team as well as an independent review, found that the error in the GNC software algorithm “prevented the system from sending the necessary pulse commands to the Reaction Control System (RCS) thrusters ahead of the stage two engine relight.” Firefly didn’t elaborate on the issue, but the RCS thrusters likely would have been used to ensure the stage was in the proper orientation and to settle its tanks so propellant would flow from them into the engine.

From this description it appears the attitude thrusters (RCS) had not worked correctly, and this made it impossible for the main engine to fire, either because the computer sensed it was in the wrong orientation, or its fuel could not flow properly to the engine.

The company says it has made corrections, and still expects to launch four times this year.

Capitalism in space: Shortly after Firefly completed the first successful orbital launch of its Alpha rocket, the U.S. Space Force awarded the company its first military launch contract.

The VICTUS NOX mission will demonstrate an end-to-end Tactically Responsive Space capability, including the launch segment, space segment, ground segment, and on-orbit operations. VICTUS NOX will perform a Space Domain Awareness (SDA) mission from Low-Earth Orbit (LEO).

The next Alpha mission, a demonstration launch of a climate smallsat for NASA, presently hopes to launch before the end of the year, though more likely early next year.

Capitalism in space: Firefly, a company that just two years ago had gone into bankruptcy, tonight successfully launched their new Alpha rocket into orbit on its second test launch. The screen capture to the right shows the rocket 1:48 minutes into flight, its first stage still firing.

A final 2nd stage engine burn has completed, and we now have confirmation of deployment of the payload satellites. My sources tell me that the second stage under-performed, putting the satellites into a 223x283km orbit, rather than the planned 300km orbit, which will shorten the lifespan of the smallsats. As this was a test launch, not an operational one, this issue does not to my mind make the launch a failure.They reached orbit and the satellites were successfully deployed.

Thus, Firefly now joins SpaceX, Rocket Lab, ULA, Virgin Orbit, and Northrop Grumman as an operational American commercial rocket companies. Astra had been operational, but it has stepped down as it builds a new rocket.

The leaders in the 2022 launch race:

43 SpaceX
41 China
12 Russia
7 Rocket Lab
6 ULA

American private enterprise now leads China 61 to 41 in the national rankings, and is tied with the entire world combined, 61 to 61.

Firefly will try again to complete the first successful launch of its Alpha rocket tonight from Vandenberg Space Force Base.

Last night they attempted twice to launch, the first aborting about 4 minutes before launch, the second aborting at T-0, with the first stage engine’s actually igniting and then shutting down.

I have embedded the live stream below. The launch window opens at 12:01 am (Pacific) and lasts two hours, giving them time for at least two launch attempts, should an abort occur on the first attempt.

UPDATE: After a first abort about T-minus 4 minutes at around midnight, the launch team quickly recycled for a new launch at 12:52 am. At T-0 the rocket then aborted at launch.

There is still more than an hour in the launch window, so assuming they can rapidly pin down the cause of the abort, another attempt is possible, though unlikely. CONFIRMED: They will try again tomorrow, with the same launch window.

Though frustrating, these repeated launch attempts are actually wonderful real time training for Firefly’s launch team. The rocket is still in good condition, and they get to practice analyzing a situation under pressure and acting quickly to move forward.

Capitalism in space: Firefly will once again attempt to complete the first successful launch of its Alpha rocket tonight, with the launch scheduled for 12:01 am (Pacific) from Vandenberg Space Force Base. The launch window lasts two hours, so if they have an abort for a minor fixable reason there is a good chance they will still be able to cycle around and try again.

I have embedded below the live feed from Everyday Astronaut, which begins at around 10 pm (Pacific), two hours before the launch.

This will be their second attempt, with the first failing one year ago when one engine in the first stage shut down prematurely due to a loose connection. They attempted to launch this second rocket for the first time earlier this month, but had to scrub due to weather.

The rocket carries five small satellites, including one, Serenity, that was built by BtB reader (and supporter) Joe Latrell, builder of cubesats in a shop behind his garage.

UPDATE: September 12th launch scrubbed due to weather. No word on when the next launch attempt will be scheduled.

Original post about September 11th scrub:
————–
After making two attempts, engineers at Firefly yesterday finally scrubbed the launch of their Alpha rocket, rescheduling the next attempt for today with a four hour launch window opening at 3 pm (Pacific).

Firefly has yet to make orbit. Their first launch attempt last year of Alpha failed when one first stage engine shut down prematurely due to a loose connection.

If you wish to watch the launch, I will embed the live stream below, once it goes live later today.

UPDATE: I have embedded the live stream below, with it beginning at 1:30 pm (Pacific).
