SpaceX considers Florida launch pad for both Falcon and Mars vehicle launches
Following a highly informative discussion at the ISS R&D conference, Elon Musk revealed that the updated, leaner version of SpaceX’s Mars architecture would likely have a diameter of around 9 meters.
A 9m Interplanetary Transport System, while precisely 25% smaller than the 12m diameter version revealed last year, would have to either lose the outer ring of full scale Raptor engines, or pivot to a smaller version of Raptor in order to preserve the 42 engine configuration shown at the IAC. Given Musk’s adamant and harsh judgement of the complexity of 27 Merlin 1D engines simultaneously firing on Falcon Heavy, moving to a 21 engine first stage for SpaceX’s Mars vehicle is a fair bet, so long as the full scale Raptor engine is still planned. Extremely speculative calculations based on the limited information available suggest that this smaller ITS could launch a bit less than half the payload of the original, still almost double the capability of Saturn V.

Possibly the most significant information to come out of this tweet is the implication that SpaceX and Musk are now looking to utilize current manufacturing facilities for the construction of a smaller ITS. While it adds considerable expense, the transport of a Space Shuttle’s external fuel tank through the streets of Los Angeles in 2011 sets a precedent for it being possible for SpaceX to transport a 9m vehicle from its factory in Hawthorne, CA to a nearby port. If SpaceX is able to use the same facilities it currently has for developing its Mars vehicle, it would experience immense savings compared to the cost of developing entirely new factories and testing facilities. This matches up perfectly with Musk’s repeated statement that the updated ITS is focused on improving the economic case for the vehicle and making it significantly cheaper to develop.
A 9m diameter vehicle fits in our existing factories …

Possibly the most crucial keystone of this economical update relates to the launch pad or pads that will be necessary to launch a rocket as large as either ITS. An oft-overlooked feature of the current LC-39A launch pad SpaceX leases and operates in Florida is that it and its LC-39B sibling were developed with a far larger and more powerful version of Saturn V in mind, known as Nova at the time. SpaceX is well aware of this, and is also painfully aware of just how expensive the construction of launch pads can be after having to undertake deep repairs of LC-40.

Buried in a fascinating article by Chris Bergin of NASASpaceflight.com fame, Bergin has revealed that documents and rumblings behind the scenes indicate that SpaceX is seriously considering either co-launching from LC-39B or modifying LC-39A with a second launch mount. This would require considerably modifications to the venerable pad, but it would not require the costly and time-consuming construction of an entirely new launch pad. Speculative renders and mockups (above) created by the skilled forum members of NASASpaceflight demonstrate this nicely, showing the launch mount for ITS and Falcon side by side.
Combined with Musk’s past statements about this updated version of ITS, the future is looking increasingly bright for what was initially a somewhat crazy architecture. Easier transport, recycled development facilities, and co-location on an already-constructed launch pad show that SpaceX are completely serious about their ambitions for Mars and are willing to do what is necessary to get to the Moon, the Red Planet, and beyond.

Tesla Fremont Factory celebrates 15 years of electric vehicle production
Since opening in 2010, the Fremont Factory has produced all four “S3XY” models while creating tens of thousands of jobs.
Tesla is marking the 15-year anniversary of its Fremont Factory in California, the first automotive mass-manufacturing plant acquired by the electric car maker.
Since opening in 2010, the Fremont Factory has produced all four “S3XY” models while creating tens of thousands of jobs and investing billions of dollars in the region.
Celebrating 15 years of EV production
The Fremont Factory’s milestone was celebrated by the official Tesla Manufacturing account on X, which posted a photo of several Teslas forming a “15” in front of the facility’s iconic white facade. As per the electric vehicle maker, the Fremont Factory has now produced 3.6 million vehicles so far, and it has also created over 20,000 jobs in the state.
“15 years ago, we opened Fremont factory. Today, the Fremont team is producing all 4 S3XY models, totaling 3.6M vehicles made so far. 20k+ California jobs created w/ billions of dollars invested,” the official Tesla Manufacturing account on X wrote in its post.
The Fremont Factory’s transformation
Tesla acquired the Fremont Factory from the defunct NUMMI joint venture between General Motors and Toyota in May 2010 for $42 million. The facility had produced more than 8 million vehicles under GM and Toyota over 26 years. Following its acquisition, Tesla retooled the 5.3-million-square-foot plant to support the production of the Model S sedan.
Over the past 15 years, the factory has evolved into Tesla’s primary North American production hub, assembling the Model S, 3, X, and Y. Annual output has exceeded 550,000 vehicles, including nearly 560,000 produced in 2023 alone. Expectations are high that other products, such as the next-generation Roadster and Optimus, might be produced in the Fremont Factory as well.

Tesla posts job opening for next-generation Roadster production
Elon Musk teased a major demonstration at the Tesla Design Studio in Hawthorne, scheduled for the end of the year.
Tesla has opened its first job listing specifically for the next-generation Roadster, hinting at some substantial progress on the company’s long-awaited flagship all-electric supercar.
The company is looking for a Manufacturing Engineer to support the development and launch of new battery manufacturing equipment, which would likely be pivotal to the Roaster, considering its teased performance and range.
Tesla’s next-generation Roadster batteries
As per Tesla’s Careers website, the Roadster Manufacturing Engineer’s tasks would include ideating equipment concepts, developing specifications, validating processes, and addressing production bottlenecks. Tesla emphasized that the position involves collaboration across domestic and international sites, supporting equipment factory acceptance tests and assisting operations teams, with expected travel under 50 percent.
“In this role, you will take large-scale manufacturing systems for new battery products and architectures from the early concept development stage through equipment launch, optimization, and handover to local operations teams. Battery development is at the heart of our company, and this is an exciting opportunity to work directly on the central challenges for the all-new Roadster product architecture while still in its early development stages,” the job listing noted.
The opening marks one of the first public hiring efforts explicitly tied to the next-gen Roadster, suggesting that the vehicle’s development might be approaching its initial manufacturing phase. The fact that the new Roadster’s first job opening is related to its battery is interesting, as the vehicle was unveiled with a range of 620 miles way back in late 2018. Though at the time, Elon Musk also noted that the Roadster would be fitted with a 200 kWh battery, twice the size of the batteries used in the Model S and Model X.
Musk teases “most epic demo ever” and fuels Roadster speculation
Back in July, Elon Musk teased a major demonstration at the Tesla Design Studio in Hawthorne, California, scheduled for the end of the year. Musk shared on X that he had just visited the studio, calling the upcoming event the “most epic demo ever by one of year. Ever.”
The statement immediately prompted speculations that Tesla may finally be ready to reveal the production version of the next-generation Roadster. Originally unveiled alongside the Semi in 2018, the Roadster has remained under wraps while the company scaled production of other models. Since its unveiling, however, the Roadster’s rollout has been pushed back in favor of the original Model Y, the refreshed Model S and X, the Cybertruck, the refreshed Model 3, the Semi, and the new Model Y.
At the time of its unveiling, the next-generation Roadster was teased to be nothing short of a monster, with a 0-60 mph time of 1.99 seconds and a top speed of over 250 mph. Elon Musk also teased that the next-generation Roadster would have a range of 620 miles per charge. Later, the CEO noted that the Roadster should be able to achieve a 0-60 mph launch of less than 1 second, thanks to the vehicle’s SpaceX package. Musk has also noted recently that the next-generation Roadster would be “beyond a car.”
