Firefly launches world’s largest carbon fiber rocket into orbit on second try
Firefly Aerospace’s Alpha rocket has successfully reached orbit on its second try, cementing the company as the victor of a mostly unintentional race between three American NewSpace startups.
After weeks of delays and three aborted launch attempts on September 11th, 12th, and 30th, the second carbon-fiber Alpha rocket lifted off from its Vandenberg Space Force Base (VSFB) SLC-2W launch pad at 12:01 am PDT (07:01 UTC) on October 1st. According to Firefly, the resulting mission was a “100%…success”, indicating that it achieved all of the company’s objectives – an outcome far from guaranteed on the second flight of any orbital rocket.
In a familiar display, Alpha’s suborbital booster lifted the upper stage, fairing, and payload most of the way out of the Earth’s atmosphere within a few minutes. After a mechanical system pushed the two stages apart, the upper stage successfully ignited its lone Lightning engine, ejected the two-piece fairing (nose cone) protecting its payloads, and continued uphill for another five minutes before reaching a stable parking orbit around 250 kilometers (~160 mi) above Earth’s surface.
After successfully reaching orbit, Alpha’s upper stage even made it through a more than 90-minute coast phase and reignited for a brief second burn. Finally, Alpha managed to deploy all seven of the satellites it lifted off with. As a test flight, there was no guarantee that those payloads would end up anywhere other than the Pacific Ocean, so the successful deployment was likely a very pleasant surprise for all satellite operators involved in the mission.
Nicknamed “Into The Black” by Firefly, it was the company’s second Alpha flight and followed an unsuccessful attempt on September 3rd, 2021. During the rocket’s first launch, a loose cable caused one of its booster’s four main Reaver engines to fail almost immediately after liftoff, dooming the attempt. However, the rest of the booster fought for more than two minutes to keep the mission on track before a termination system destroyed the rocket, demonstrating otherwise excellent performance and gathering invaluable data and experience.
Firefly wasted no time putting that experience to good use. Compared to the first vehicle, the booster and upper stage for Alpha’s second flight sailed through preflight testing and completed their respective proof tests (a combined wet dress rehearsal and static fire) on their first tries. That smooth processing bodes well for the timing of Firefly’s third Alpha launch, although the company’s official accounts have strangely been almost silent after Flight 2’s success.
Soon after launch, third-party data showed that Alpha deployed its seven payloads into a 210 x 270 kilometer (130 x 170 mi) orbit. Firefly’s official launch page had stated that the target orbit was 300 kilometers (~185 mi) and called the second ignition of the upper stage a “circularization burn.” Given that the final orbit is far from circular and has an apogee a full 10% below that stated target, it wasn’t clear the rocket had performed exactly as expected. The orbit’s very low perigee means that the customer satellites Alpha deployed could reenter Earth’s atmosphere and burn up after a matter of weeks in space, rather than months or years.
But according to Bill Weber, who became CEO of Firefly less than a month before the launch, Alpha “deployed [Firefly’s] customer payloads at exactly the spot [the company] intended,” strongly implying that the strange final orbit was intentional.
Additionally, official footage Firefly released after the launch suggests that Alpha’s upper stage Lightning engine nozzle narrowly missed the booster’s interstage during stage separation. Had the drifting booster hit that nozzle, it would have likely caused the upper stage to begin tumbling and potentially ended the mission well before orbit. Thankfully, it didn’t, and it should be relatively easy to fix whatever caused the Alpha booster to begin slipping sideways so quickly after separation.
Alpha is the largest all-carbon-fiber rocket ever built. It stands 29.5 meters (~95 ft) tall, 1.8 meters (6 ft) wide, weighs 54 tons (~120,000 lb) fully fueled, and can produce up 81 tons of thrust (~180,000 lbf). Alpha can launch up to 1.17 tons ~(2600 lb) of useful cargo to low Earth orbit (LEO), making it the first successful entrant in a new and rapidly growing field of privately-developed rockets designed to launch 1-2 tons to orbit.
Coincidentally, Firefly found itself neck and neck with two other prospective US providers, Relativity Space and ABL Space. For several months, all three companies were aiming to successfully launch their one-ton-class rockets to orbit sometime in the late summer or early fall. But despite delays, Firefly – already more than a year ahead after its first launch attempt in 2021 – still beat Relativity and ABL Space to flight and did so successfully, securing itself a small but significant milestone in the history of private spaceflight.
The timeline for Relativity’s first 3D-printed Terran-1 rocket launch is no longer clear after a hurricane disrupted its preflight test campaign. ABL Space, meanwhile, has been forced to sit with its first RS1 rocket ready to launch for weeks while waiting on the FAA to complete paperwork and grant it a launch license. Had the FAA moved faster, it’s entirely possible that ABL Space could have launched before Firefly’s Alpha Flight 2, although the odds of success are much lower for RS1 during its debut. Pending that regulatory approval, ABL Space intends to launch RS1 out of Kodiak, Alaska as early as mid-October.
Firefly has yet to offer a substantial statement after the successful launch, which means that the company has provided no information about its next steps or next launch. Per prior statements, the company is working to upgrade its Texas factory to enable up to six Alpha launches in 2023.

Tesla FSD (Supervised) fleet passes 8.4 billion cumulative miles
Tesla’s Full Self-Driving (Supervised) system has now surpassed 8.4 billion cumulative miles.
The figure appears on Tesla’s official safety page, which tracks performance data for FSD (Supervised) and other safety technologies.
Tesla has long emphasized that large-scale real-world data is central to improving its neural network-based approach to autonomy. Each mile driven with FSD (Supervised) engaged contributes additional edge cases and scenario training for the system.
The milestone also brings Tesla closer to a benchmark previously outlined by CEO Elon Musk. Musk has stated that roughly 10 billion miles of training data may be needed to achieve safe unsupervised self-driving at scale, citing the “long tail” of rare but complex driving situations that must be learned through experience.
The growth curve of FSD Supervised’s cumulative miles over the past five years has been notable.
As noted in data shared by Tesla watcher Sawyer Merritt, annual FSD (Supervised) miles have increased from roughly 6 million in 2021 to 80 million in 2022, 670 million in 2023, 2.25 billion in 2024, and 4.25 billion in 2025. In just the first 50 days of 2026, Tesla owners logged another 1 billion miles.
At the current pace, the fleet is trending towards hitting about 10 billion FSD Supervised miles this year. The increase has been driven by Tesla’s growing vehicle fleet, periodic free trials, and expanding Robotaxi operations, among others.
With the fleet now past 8.4 billion cumulative miles, Tesla’s supervised system is approaching that threshold, even as regulatory approval for fully unsupervised deployment remains subject to further validation and oversight.

Elon Musk fires back after Wikipedia co-founder claims neutrality and dubs Grokipedia “ridiculous”
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Elon Musk fired back at Wikipedia co-founder Jimmy Wales after the longtime online encyclopedia leader dismissed xAI’s new AI-powered alternative, Grokipedia, as a “ridiculous” idea that is bound to fail.
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Wales made the comments while answering questions about Wikipedia’s neutrality. According to Wales, Wikipedia prides itself on neutrality.
“One of our core values at Wikipedia is neutrality. A neutral point of view is non-negotiable. It’s in the community, unquestioned… The idea that we’ve become somehow ‘Wokepidea’ is just not true,” Wales said.
When asked about potential competition from Grokipedia, Wales downplayed the situation. “There is no competition. I don’t know if anyone uses Grokipedia. I think it is a ridiculous idea that will never work,” Wales wrote.
After Grokipedia went live, Larry Sanger, also a co-founder of Wikipedia, wrote on X that his initial impression of the AI-powered Wikipedia alternative was “very OK.”
“My initial impression, looking at my own article and poking around here and there, is that Grokipedia is very OK. The jury’s still out as to whether it’s actually better than Wikipedia. But at this point I would have to say ‘maybe!’” Sanger stated.
Musk responded to Sanger’s assessment by saying it was “accurate.” In a separate post, he added that even in its V0.1 form, Grokipedia was already better than Wikipedia.
During a past appearance on the Tucker Carlson Show, Sanger argued that Wikipedia has drifted from its original vision, citing concerns about how its “Reliable sources/Perennial sources” framework categorizes publications by perceived credibility. As per Sanger, Wikipedia’s “Reliable sources/Perennial sources” list leans heavily left, with conservative publications getting effectively blacklisted in favor of their more liberal counterparts.
As of writing, Grokipedia has reportedly surpassed 80% of English Wikipedia’s article count.

Tesla Sweden appeals after grid company refuses to restore existing Supercharger due to union strike
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons.
Tesla Sweden is seeking regulatory intervention after a Swedish power grid company refused to reconnect an already operational Supercharger station in Åre due to ongoing union sympathy actions.
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons. A temporary construction power cabinet supplying the station had fallen over, described by Tesla as occurring “under unclear circumstances.” The power was then cut at the request of Tesla’s installation contractor to allow safe repair work.
While the safety issue was resolved, the station has not been brought back online. Stefan Sedin, CEO of Jämtkraft elnät, told Dagens Arbete (DA) that power will not be restored to the existing Supercharger station as long as the electric vehicle maker’s union issues are ongoing.
“One of our installers noticed that the construction power had been backed up and was on the ground. We asked Tesla to fix the system, and their installation company in turn asked us to cut the power so that they could do the work safely.
“When everything was restored, the question arose: ‘Wait a minute, can we reconnect the station to the electricity grid? Or what does the notice actually say?’ We consulted with our employer organization, who were clear that as long as sympathy measures are in place, we cannot reconnect this facility,” Sedin said.
The union’s sympathy actions, which began in March 2024, apply to work involving “planning, preparation, new connections, grid expansion, service, maintenance and repairs” of Tesla’s charging infrastructure in Sweden.
Tesla Sweden has argued that reconnecting an existing facility is not equivalent to establishing a new grid connection. In a filing to the Swedish Energy Market Inspectorate, the company stated that reconnecting the installation “is therefore not covered by the sympathy measures and cannot therefore constitute a reason for not reconnecting the facility to the electricity grid.”
Sedin, for his part, noted that Tesla’s issue with the Supercharger is quite unique. And while Jämtkraft elnät itself has no issue with Tesla, its actions are based on the unions’ sympathy measures against the electric vehicle maker.
“This is absolutely the first time that I have been involved in matters relating to union conflicts or sympathy measures. That is why we have relied entirely on the assessment of our employer organization. This is not something that we have made any decisions about ourselves at all.
“It is not that Jämtkraft elnät has a conflict with Tesla, but our actions are based on these sympathy measures. Should it turn out that we have made an incorrect assessment, we will correct ourselves. It is no more difficult than that for us,” the executive said.
