SpaceX hot-fires Crew Dragon’s Falcon 9 as separate rocket spied in Arizona
A SpaceX Falcon 9 booster has been spotted traveling eastbound through Wilcox, AZ, indicating a shipment from the company’s Hawthorne, CA rocket factory to its McGregor, TX facilities for hot-fire acceptance testing.
Captured by Reddit user codercotton on October 28th, this first stage (S1) is headed to Texas at the same time as SpaceX’s facilities appear to be wrapping up an extended test campaign with the Falcon 9 rocket stages that will launch an uncrewed Crew Dragon on the upgraded spacecraft’s first trip into orbit.

This duo of Falcon 9 appearances highlights an unusual few months of what is often called “core spotting” by close followers of SpaceX. Typically, SpaceX ships and hot-fire tests a Falcon 9 booster every month, give or take roughly two weeks. It’s clear, however, that the imminent start of Crew Dragon launches under NASA’s Commercial Crew Program (CCP) has created some unique requirements with respect to both booster, upper stage, and individual engine testing in Texas.
For example, Falcon 9 B1051 – a new booster assigned to Crew Dragon’s first uncrewed demonstration launch (DM-1) – appears to have been testing in McGregor for the better part of three months, apparently including multiple hot-fire tests of the rocket. Prior to Commercial Crew, a nominal round of acceptance testing in McGregor would be expected to last between two and four weeks between arrival and departure. As such, spending three months or more in McGregor is very unusual, particularly for a brand-new booster like B1051.
B1051’s extended period of testing can likely be traced back to two main factors. At a more technical level, B1051 could be the first Falcon 9 Block 5 booster to have SpaceX’s upgraded COPVs (carbon-overwrapped pressure vessels) – bottles designed to hold helium and nitrogen at pressures around 5000 psi (35 MPa) – fully integrated on both the first and second stages. Perhaps not a major technical hurdle for SpaceX, this milestone is undoubtedly one of NASA’s most myopic and obsessive mountains-out-of-molehills in terms of the intense ‘certification’ burdens dumped on SpaceX over the course of CCP. SpaceX has apparently spent at least 1.5 years systematically designing, testing to destruction, and redesigning an in-house COPV, to the extent that CEO Elon Musk described the updated design as “by far the most advanced pressure vessel ever developed by humanity … It’s nuts.”

Juggling Falcon 9 tests
Despite the extreme lengths of testing apparently required for the Falcon 9s that will launch Crew Dragon, it can be concluded with some certainty that SpaceX has still managed to fit in normal tests of a number of non-Crew boosters, upper stages, and Merlins. According to the above SpaceX tweet, B1051 is clearly still in Texas and is unlikely to leave for Florida until November (several days are needed to prepare a booster for transport). However, a different booster was spotted heading from California to Texas just this morning.
Further, Falcon 9 booster B1054 – nearly complete and stationed in front of the only real exit route – was spotted in SpaceX’s Hawthorne factory in mid-September, while an unknown first stage was caught departing the factory for Texas roughly two weeks later. Finally, at the same time as the mystery booster was being trucked to Texas, an even more mysterious Falcon 9 – visibly sooty and thus flight-proven – was spotted inside one of SpaceX Hawthorne’s separate refurbishment hangars, with at least three Merlins removed from its octaweb. Perhaps this is somehow related to the Falcon 9 booster (missing four of nine Merlins) headed East on October 28th.
Finally, according to a member of the /r/SpaceX subreddit, a separate Falcon 9 booster apparently arrived at SpaceX’s Vandenberg, CA launch facilities on October 26th, perhaps Falcon 9 B1046.3 preparing to launch for the third time for Spaceflight’s SSO-A rideshare mission, NET November 19.

As with most things SpaceX, definitive answers are exceedingly rare when it comes to day-to-day operations like Falcon 9 transportation and even official confirmation of the particular boosters involved with any given launch. Understandably, these more esoteric details are probably treated as “need-to-know” only, and while I and many others would love to know, we certainly don’t *need* to know.

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.
Investor's Corner
SpaceX IPO is coming, CEO Elon Musk confirms
However, it appears Musk is ready for SpaceX to go public, as Ars Technica Senior Space Editor Eric Berger wrote an op-ed that indicated he thought SpaceX would go public soon. Musk replied, basically confirming it.
Elon Musk confirmed through a post on X that a SpaceX initial public offering (IPO) is on the way after hinting at it several times earlier this year.
It also comes one day after Bloomberg reported that SpaceX was aiming for a valuation of $1.5 trillion, adding that it wanted to raise $30 billion.
Musk has been transparent for most of the year that he wanted to try to figure out a way to get Tesla shareholders to invest in SpaceX, giving them access to the stock.
He has also recognized the issues of having a public stock, like litigation exposure, quarterly reporting pressures, and other inconveniences.

Berger believes the IPO would help support the need for $30 billion or more in capital needed to fund AI integration projects, such as space-based data centers and lunar satellite factories. Musk confirmed recently that SpaceX “will be doing” data centers in orbit.
AI appears to be a “key part” of SpaceX getting to Musk, Berger also wrote. When writing about whether or not Optimus is a viable project and product for the company, he says that none of that matters. Musk thinks it is, and that’s all that matters.
It seems like Musk has certainly mulled something this big for a very long time, and the idea of taking SpaceX public is not just likely; it is necessary for the company to get to Mars.
The details of when SpaceX will finally hit that public status are not known. Many of the reports that came out over the past few days indicate it would happen in 2026, so sooner rather than later.
But there are a lot of things on Musk’s plate early next year, especially with Cybercab production, the potential launch of Unsupervised Full Self-Driving, and the Roadster unveiling, all planned for Q1.

SpaceX reportedly mulling IPO, eyeing largest of all time: report
“I do want to try to figure out some way for Tesla shareholders to participate in SpaceX. I’ve been giving a lot of thought to how to give people access to SpaceX stock,” Musk said.
SpaceX is reportedly mulling an initial public offering, eyeing what would be the largest valuation at the time of availability of all time, a new report from Bloomberg said on Tuesday.
It is one of many reports involving one of Elon Musk’s companies and a massive market move, as this is not the first time we have seen reports of an IPO by SpaceX. Musk himself has also dispelled other reports in the past of a similar nature, including an xAI funding round.
SpaceX and Musk have yet to comment on the report. In the past, untrue reports were promptly replied to by the CEO; this has not yet gained any response, which is a good sign in terms of credibility.
However, he said just a few days ago that stories of this nature are inaccurate:
“There has been a lot of press claiming SpaceX is raising money at $800B, which is not accurate. SpaceX has been cash flow positive for many years and does periodic stock buybacks twice a year to provide liquidity for employees and investors. Valuation increments are a function of progress with Starship and Starlink and securing global direct-to-cell spectrum that greatly increases our addressable market. And one other thing that is arguably most significant by far.”

Musk has discussed a potential IPO for SpaceX in recent months, as the November 6 shareholder meeting, as he commented on the “downsides” of having a public company, like litigation exposure, quarterly reporting pressures, and other inconveniences.
Nevertheless, Musk has also said he wants there to be a way for Tesla shareholders to get in on the action. At the meeting in early November, he said:
“I do want to try to figure out some way for Tesla shareholders to participate in SpaceX. I’ve been giving a lot of thought to how to give people access to SpaceX stock.”
Additionally, he added:
“Maybe at some point., SpaceX should become a public company despite all the downsides of being public.”
Musk has been historically reluctant to take SpaceX public, at times stating it could become a barrier to colonizing Mars. That does not mean it will not happen.
Bloomberg’s report cites multiple unidentified sources who are familiar with the matter. They indicate to the publication that SpaceX wants to go public in mid-to-late 2026, and it wants to raise $30 billion at a valuation of around $1.5 trillion.
This is not the first time SpaceX has discussed an IPO; we reported on it nine years ago. We hope it is true, as the community has spoken for a long time about having access to SpaceX stock. Legendary investor Ron Baron is one of the lucky few to be a SpaceX investor, and said it, along with Tesla, is a “lifetime investment.”

The primary driver of SpaceX’s value is Starlink, the company’s satellite internet service. Starlink contributes 60-70 percent of SpaceX’s revenue, meaning it is the primary value engine. Launch services, like Falcon 9 contracts, and the development of Starship, also play supporting roles.
