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.

SpaceX reportedly discussing merger with xAI ahead of blockbuster IPO
In a groundbreaking new report from Reuters, SpaceX is reportedly discussing merger possibilities with xAI ahead of the space exploration company’s plans to IPO later this year, in what would be a blockbuster move.
The outlet said it would combine rockets and Starlink satellites, as well as the X social media platform and AI project Grok under one roof. The report cites “a person briefed on the matter and two recent company filings seen by Reuters.”
Musk, nor SpaceX or xAI, have commented on the report, so, as of now, it is unconfirmed.
With that being said, the proposed merger would bring shares of xAI in exchange for shares of SpaceX. Both companies were registered in Nevada to expedite the transaction, according to the report.
On January 21, both entities were registered in Nevada. The report continues:
“One of them, a limited liability company, lists SpaceX and Bret Johnsen, the company’s chief financial officer, as managing members, while the other lists Johnsen as the company’s only officer, the filings show.”
The source also stated that some xAI executives could be given the option to receive cash in lieu of SpaceX stock. No agreement has been reached, nothing has been signed, and the timing and structure, as well as other important details, have not been finalized.
SpaceX is valued at $800 billion and is the most valuable privately held company, while xAI is valued at $230 billion as of November. SpaceX could be going public later this year, as Musk has said as recently as December that the company would offer its stock publicly.
The plans could help move along plans for large-scale data centers in space, something Musk has discussed on several occasions over the past few months.
At the World Economic Forum last week, Musk said:
“It’s a no-brainer for building solar-powered AI data centers in space, because as I mentioned, it’s also very cold in space. The net effect is that the lowest cost place to put AI will be space and that will be true within two to three years, three at the latest.”
He also said on X that “the most important thing in the next 3-4 years is data centers in space.”
If the report is true and the two companies end up coming together, it would not be the first time Musk’s companies have ended up coming together. He used Tesla stock to purchase SolarCity back in 2016. Last year, X became part of xAI in a share swap.

SpaceX Starship V3 gets launch date update from Elon Musk
The first flight of Starship Version 3 and its new Raptor V3 engines could happen as early as March.
Elon Musk has announced that SpaceX’s next Starship launch, Flight 12, is expected in about six weeks. This suggests that the first flight of Starship Version 3 and its new Raptor V3 engines could happen as early as March.
In a post on X, Elon Musk stated that the next Starship launch is in six weeks. He accompanied his announcement with a photo that seemed to have been taken when Starship’s upper stage was just about to separate from the Super Heavy Booster. Musk did not state whether SpaceX will attempt to catch the Super Heavy Booster during the upcoming flight.
The upcoming flight will mark the debut of Starship V3. The upgraded design includes the new Raptor V3 engine, which is expected to have nearly twice the thrust of the original Raptor 1, at a fraction of the cost and with significantly reduced weight. The Starship V3 platform is also expected to be optimized for manufacturability.
The Starship V3 Flight 12 launch timeline comes as SpaceX pursues an aggressive development cadence for the fully reusable launch system. Previous iterations of Starship have racked up a mixed but notable string of test flights, including multiple integrated flight tests in 2025.
Interestingly enough, SpaceX has teased an aggressive timeframe for Starship V3’s first flight. Way back in late November, SpaceX noted on X that it will be aiming to launch Starship V3’s maiden flight in the first quarter of 2026. This was despite setbacks like a structural anomaly on the first V3 booster during ground testing.
“Starship’s twelfth flight test remains targeted for the first quarter of 2026,” the company wrote in its post on X.

Elon Musk shares insights on SpaceX and Tesla’s potential scale
In a pair of recent posts on X, Musk argued that both companies operate in domains where growth is not linear, but exponential.
Elon Musk outlined why he believes Tesla and SpaceX ultimately dwarf their competitors, pointing to autonomy, robotics, and space-based energy as forces that fundamentally reshape economic scale.
In a pair of recent posts on X, Musk argued that both companies operate in domains where growth is not linear, but exponential.
Space-based energy
In a response to a user on X who observed that SpaceX has a larger valuation than all six US defense companies combined, Musk explained that space-based industries will eventually surpass the total economic value of Earth. He noted that space allows humanity to harness roughly 100,000 times more energy than Earth currently uses, while still consuming less than a millionth of the Sun’s total energy output.
That level of available energy should enable the emergence and development of industries that are simply not possible within Earth’s physical and environmental constraints. Continuous solar exposure in space, as per Musk’s comment, removes limitations imposed by atmosphere, weather, and land availability.
Autonomy and robots
In a follow-up post, Elon Musk explaned that “due to autonomy, Tesla is worth more than the rest of the auto industry.” Musk added that this assessment does not yet account for Optimus, Tesla’s humanoid robot. As per the CEO, once Optimus reaches scaled production, it could increase Earth’s gross domestic product by an order of magnitude, ultimately paving the way for sustainable abundance.
Even before the advent of Optimus, however, Tesla’s autonomous driving system already gives vehicles the option to become revenue-generating assets through services like the Tesla Robotaxi network. Tesla’s autonomous efforts seem to be on the verge of paying off, as services like the Robotaxi network have already been launched in its initial stages in Austin and the Bay Area.
