SpaceX’s next-gen Falcon Heavy closer to reality as side booster leaves factory
A duo of rocket spottings on November 9th and 10th confirm that SpaceX’s next Falcon Heavy rocket – an amalgamation of three Falcon 9 boosters, an upper stage, and extensive modifications – is already in the late stages of manufacturing and is nearing the beginning of integrated structural and static fire testing.
As of now, this Falcon Heavy side booster could end up supporting either or both of two near-term launch contracts in place for the rocket, communications satellite Arabsat 6A or the US Air Force’s second Space Test Program (STP-2) launch

The question of the hour – at least for Falcon Heavy – is which of those two available payloads will be atop the rocket on its first truly commercial launch. While suboptimal, a few general characteristics of each payload, SpaceX’s history of commercial launches, and Falcon Heavy itself can offer a hint or two.
Triple the rocket, triple the trouble
Thanks in large part to the fact that the first integrated Falcon Heavy was composed of two relatively old Falcon 9 booster variants and a center core that was quite literally a one-off rocket, the process of reenginering and building another Falcon Heavy rocket off of the family’s newest Block 5 variant has likely been far harder than simply building another Falcon Heavy. Although all three original Falcon Heavy boosters (B1023, B1025, and B1033) were in the same league as Block 5, their Block 2 and Block 3 hardware was designed for approximately 10% less thrust and are almost entirely different vehicles from the perspective of structures and avionics.
Perhaps even more importantly, it’s unknown whether Falcon Heavy Block 1 (for lack of a better descriptor) was designed with serious reusability in mind, at least in the same sense as Falcon 9 Block 5 was. For instance, a major portion of the rocket’s extreme complexity and difficulties lies in the basic need to transmit three times as much thrust through the center core. To do that and do it without rocket-powered separation mechanisms, SpaceX had to develop structural attachments and connections capable of surviving unbelievable mechanical and thermal stresses for minutes on end.

Clearly, this was an unfathomably difficult problem to solve in such a manner that Falcon Heavy would work at all the first time. Factor in the strategic need for those same components to survive repeated cycles of those stresses with minimal refurbishment in between and the problem at hand likely becomes a magnitude more difficult, at least. In large part, this helps to explain why there will end up being a minimum of 11-12 months between Falcon Heavy’s first and second launches.
Arabsat or STP?
Over the course of SpaceX’s last 2-3 years of commercial launch activity, the company and its customers have demonstrated time and time again a reliable pattern: commercial customers (in the sense of private entities) are far more willing to take risks with new technologies than SpaceX’s government customers. NASA’s Commercial Resupply Services is the exception for the latter group but also has no Falcon Heavy launch contracts. For Falcon Heavy, there are thus main three options at hand.
- Arabsat 6A launches first with 1-2 flight-proven boosters; the Air Force’s STP-2 mission flies on an all-new Falcon Heavy 4-6 months later.
- SpaceX builds entirely new Falcon Heavy rockets for both customers, requiring four new side boosters and two new center cores.
- STP-2 launches first on an all-new Falcon Heavy; Arabsat 6A launches second on the first flight-proven Falcon Heavy after 6+ months of additional delays.

Arabsat is far more likely to accept – for a significant discount – a ride aboard the first flight-proven Falcon Heavy, especially if it means preventing more major launch delays. If the Falcon Heavy side booster spotted eastbound last week is a refurbished Block 5 booster rather than a new rocket, than option 1 is the easy choice for most probable outcome. The real pack leader for Falcon Heavy Flight 2, however, will be the completion of a new Block 5 center core and its shipment to Texas for structural and static fire testing.
Time will tell. For now, a completed Falcon Heavy side booster is the best sign yet that SpaceX may manage the rocket’s second launch in the first quarter of 2019, whichever launch that may be.

Tesla Semi factory is getting a celebration nobody expected
Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.
Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.
While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.
Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.
The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.

Elon Musk just set a condition that could end Falcon 9 as we know it
Elon Musk says SpaceX will finally retire Falcon 9 once Starship flies reliably every week.
Elon Musk gave the clearest timeline yet for retiring Falcon 9, SpaceX’s workhorse rocket.
The comment came in a reply on X, where Musk wrote that “once Starship is flying reliably several times per week, it makes sense to shift super scarce SpaceX engineering and production resources to Starship to get launch rate to several times per day, which means winding down Falcon.” He was responding to physicist Casey Handmer, who noted that NASA is reportedly uneasy about SpaceX phasing out Falcon after building what Handmer called the most successful launcher ever, with the fleet nearing 1,000 total launches.
Now @SciGuySpace reports NASA is in a tizzy because after running the most successful launcher ever for more than a decade and nearing 1000 launches, @SpaceX is planning to retire Falcon in favor of Starship in a few years.
Sorry, NASA, you’ve had 15 years to burn down the… https://t.co/uCNoMwK0v9

Falcon 9 is still SpaceX’s busiest vehicle by far. The company is on pace for roughly 140 to 145 Falcon flights this year, following 165 in 2025, president Gwynne Shotwell told Time earlier in 2026. She has already said Falcon flights would “tail off” as Starship comes online, while reports indicate that SpaceX has stopped booking new Falcon 9 launches past 2028 and halted production of some expendable Falcon hardware, according to Bloomberg.
It’s worth noting that Musk’s post is a condition, and not a countdown on when Falcon will retire. Starship has not yet flown weekly, let alone daily. Its most recent flight in July ended with a soft splashdown in the Indian Ocean, a milestone Musk pointed to earlier this month when he said the vehicle’s heat shield problem was effectively solved. SpaceX towed that ship to Christmas Island for inspection, and the next flight, Flight 14, is aimed at putting Starship into orbit for the first time. A tower catch attempt for the upper stage has been pushed back to what Musk has called “a few months” away.
SpaceX and a new Trump order that could rewrite the next decade of launches
The gap between Falcon’s role today and Starship’s promised role tomorrow matters most to NASA. Falcon and its Dragon capsule remain the only way the agency rotates astronauts to and from the International Space Station, and Starship is not certified to carry NASA crews. Musk’s post did not address how that handoff would work if Falcon winds down before a crew-rated Starship variant exists. The timing lines up with Musk’s other recent Starship comments. Two days before the Falcon post, he told a different X user that SpaceX is aiming for more than 30 Starship launches a day by 2030, or roughly 10,000 a year, a figure tied to the Trump administration’s new push for higher national launch cadence. Falcon, which took over a decade to reach its first 100 launches, was never built to approach that kind of volume.
For now, Falcon 9 keeps flying at a near-record pace while Starship works to prove it can do the job Musk has already picked out for it.
Tesla Cybercab is set to launch in Austin, Texas, on September 3, as the company has officially started sending out invitations to a dedicated event it will hold in the city where its headquarters is located.
The Cybercab is Tesla’s dedicated ride-sharing vehicle: it features just two seats and has no steering wheel or pedals. It is aimed at fully autonomous passenger transport, and will operate in the Robotaxi fleet alongside the Tesla Model Y, which has been performing driverless rides for real-world passengers for more than a year.
Thank you so much @Tesla for inviting us to the Cybercab launch in Austin! 🤠 pic.twitter.com/F1rAR8zd5O

The launch of the Cybercab marks the next chapter in Tesla’s autonomy story. The company has been developing autonomous transport for years with its Full Self-Driving (Supervised) platform, which is available in any vehicle the company has built with the proper hardware and software capabilities.
Its capabilities vary by hardware and software version, but Tesla says its latest hardware version, known as AI4, can deliver full autonomy. However, future vehicles will operate with even more robust hardware packages, as Tesla will develop AI4.5 and AI5 for even more capability in its vehicles.
Following a report from The Information that surfaced earlier this week, the writing was on the wall that Tesla was set to launch Cybercab in the near term. The report stated Tesla could launch Cybercab as soon as the end of August. Tesla came close and has booked it for September 3.
The big thing with this event being scheduled is not necessarily that Tesla is launching a new vehicle, but instead that it is launching a vehicle that has no steering wheel or pedals and will operate exclusively on a self-driving program that is evidently nearing full autonomy. If the event allows vehicles to take passengers on public roads and drop them off wherever they please within the City of Austin, it will be a drastic advancement in the company’s self-driving story.
People have ridden in Cybercab previously: Tesla had the “We, Robot” event in October 2024, which allowed people to experience fully autonomous rides in a closed circuit at Warner Bros. Studios in Burbank.

Additionally, Tesla launched employee rides in Cybercab in July.
It’s a drastic step forward for Tesla, whose CEO, Elon Musk, has promised for years that the company would release a fully autonomous vehicle and platform capable of allowing drivers to relinquish any responsibility behind the wheel.
