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 has officially acquired xAI, merging rockets with AI expertise in what is the first move to bring Elon Musk’s companies under one umbrella.
On February 2, SpaceX officially announced the acquisition of xAI, uniting two powerhouse companies under a single entity, creating what the space exploration company called in a blog post “one of the most ambitious, vertically integrated innovation engines on (and off) Earth.”

The deal will integrate xAI’s advanced AI capabilities, including the Grok chatbot and massive training infrastructure, with SpaceX’s rocket technology, Starlink satellite network, and ambitious space exploration goals.
The acquisition comes at a pivotal moment: xAI is valued at around $230 billion as of late 2025, and has been racing to scale AI compute amid global competition from companies like OpenAI, Google, and Meta. Meanwhile, SpaceX, which was recently valued at $800 billion, is facing escalating costs for its multiplanetary ambitions.
By combining forces, the merged entity gains a unified approach to tackle one of AI’s biggest bottlenecks: the enormous energy and infrastructure demands of next-gen models.
Musk wrote in a blog post on SpaceX’s website that:
“In the long term, space-based AI is obviously the only way to scale. To harness even a millionth of our Sun’s energy would require over a million times more energy than our civilization currently uses! The only logical solution therefore is to transport these resource-intensive efforts to a location with vast power and space. I mean, space is called “space” for a reason.”
Musk details the need for orbital data centers, stating that his estimate is that “within 2 to 3 years, the lowest cost way to generate AI compute will be in space.
This cost-efficiency alone will enable innovative companies to forge ahead in training their AI models and processing data at unprecedented speeds and scales, accelerating breakthroughs in our understanding of physics and invention of technologies to benefit humanity.”
SpaceX recently filed for approval from the FCC to launch up to one million solar-powered satellites configured as high-bandwidth, optically linked compute platforms.
These facilities would harness near-constant sunlight with minimal maintenance, delivering what the company projects as transformative efficiency.
Musk has long argued that space offers the ultimate solution for power-hungry AI projects. But that’s not all the merger will take care of.
Additionally, it positions the company to fund broader goals. Revenue from the Starlink expansion, potential SpaceX IPO, and AI-driven applications could accelerate the development of lunar bases, as Musk believes multiplanetary life will be crucial to saving civilization.
Critics question the feasibility of massive constellations amid orbital debris concerns and regulatory hurdles. Yet, proponents see it as a bold step toward a multiplanetary computing infrastructure that extends human civilization beyond Earth.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
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.
