SpaceX set for expendable Falcon 9 Block 5 launch attempt after 48 hour scrub
Following a reported bug with Falcon 9 booster sensors that triggered a launch abort on the morning of December 18th, SpaceX has mitigated those problems and is ready to try again, hopefully placing the first of 10 new USAF GPS III satellites into orbit shortly after a 9:03 am EST (14:03 UTC) liftoff on December 20th.
Aside from being the first time SpaceX has launched a dedicated USAF mission won through a competitive procurement process, the launch of GPS III Space Vehicle 1 (SV01) will also be the first time SpaceX has intentionally expended a new Falcon 9 booster since July 2017, as well as the first time ever that a Falcon 9 Block 5 booster will be expended without attempting to land.
Team is working toward launch of GPS III SV01 tomorrow, December 20. Weather remains a challenge; currently forecasted at 20% favorable during the 26-minute launch window which opens at 9:03 a.m. EST, 14:03 UTC.

Standing vertical at SpaceX’s Launch Complex 40 (LC-40) pad, Block 5 booster B1054 looks undeniably incomplete or just off without grid fins and landing legs installed, like toast without butter or a Tesla with a V8 in place of its electric motors. The fact that Falcon 9 B1054 is a brand-new booster simply throws salt on the wound. However, the expendable configuration does serve as a reminder that, when it really comes down to it, SpaceX’s launch customers with as much sway as the Air Force ultimately have a major (if not final) say in the rocket’s trajectory.
If a customer demands an almost ridiculous level of redundancy, SpaceX likely has little to no say in that decision, even if it means that a brand new Falcon 9 Block 5 booster – designed to launch anywhere from 10-100 times in its lifetime – will have to be disposed of in the ocean after just one. While the performance-based decision to expend Falcon 9 appears to be far more of a security blanket than a practical necessity, it does still serve as a reminder that some exceptionally heavy payloads and/or high-energy orbits will inevitably preclude Falcon 9 or even Falcon Heavy from attempting booster landings. Down the road, major NASA or national security payloads will likely continue to demand expendable configurations, at least until BFR (Starship/Super Heavy) can take over from Falcon 9 and Heavy.

Although SpaceX does appear to be serious Thursday’s launch attempt, the weather conditions are far from desirable thanks to the forecasted presence of “Electric Field, Cumulus/Thick Cloud, Disturbed Weather”, as well as the likelihood of strong upper-level winds near the Florida coast. With just a 20% chance that weather conditions will permit a launch and a brief 26-minute window of opportunity, there is little to no wiggle room for SpaceX to wait for a figurative break in the clouds, and another scrub seems extremely likely.
If the weather does force SpaceX to call off Thursday’s attempt, additional opportunities appear to be available on Friday (60% favorable) and Saturday (80% favorable). For now, however, Falcon 9 B1054 appears to have bought itself a few extra days to continue being an intact and (mostly) dry rocket. Catch the watch live at the link below.

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.
