SpaceX Falcon Heavy testing delayed after government shutdown
As the U.S. Senate’s majority party searches for ten additional votes in order to end a federal government shutdown that began late Saturday, all “non-essential” activities at the country’s numerous government-operated space launch facilities have ground to an immediate halt and will remain in limbo until a funding bill compromise is hammered out.
While SpaceX is a wholly private space launch company, it relies almost unilaterally upon launch support and range expertise provided by NASA and the US Air Force, both in Cape Canaveral, FL and Vandenberg, CA. Sadly, the Air Force personnel SpaceX depend upon to conduct launches, static fires, and other ignition tests at its launch pads are not considered “essential” under regulations that prevent the federal government from coming to a complete halt in the event of a funding-related shutdown.
Unfortunately, a budget agreement wasn't reached, resulting in a gov't shutdown. This will unfortunately disrupt the lives and operations here at Patrick AFB. Go to https://t.co/yvmNBH1LMy for info on the current shutdown, impact on base resources, & financial resource options.

SpaceX did appear to complete the most thorough round of Falcon Heavy testing yet late Saturday evening, the US Senate’s failure to either pass a continuing resolution or a new funding bill for the fiscal year led to a complete federal government shutdown soon after. As a result, nearly all of the US Air Force’s 45th Space Wing – a crucial backbone of East coast range and launch operations – was furloughed indefinitely, pending new funding from Congress. SpaceX had previously requested a new static fire date for Falcon Heavy on Monday, January 22 (today), a date that is now clearly going to move right for at least as long as the government lacks funding for basic launch operations.
Thankfully, activities like the extensive propellant loading tests that occurred on Saturday night do not technically require range support, so long as no engine ignition or static fire components are included. In the event of a catastrophic failure, the government-run range would be tasked with ensuring the safety of those in the vicinity and coordinating the emergency response that would immediately follow. This policy is brought somewhat into question by the failure of Amos-6 – although that Falcon 9 was being prepared for a static fire test, its highly-destructive failure is understood to have occurred at least five or more minutes before the planned point of ignition. Nevertheless, SpaceX will be able to continue some level of testing with Falcon Heavy, if needed.
Elsewhere, instability
While SpaceX’s Falcon Heavy has undoubtedly garnered magnitudes more eyeballs than the company’s Falcon 9 activities, the government shutdown could be far more consequential for SpaceX’s customers if it cannot be halted within a handful of days. A federal shutdown lasting several days is a hugely disruptive and damaging event on its own, lack of range support on the East coast could quickly begin to eat into SpaceX’s GovSat-1 preparations, the launch of which is targeting NET late January/January 30. For GovSat-1’s flight-proven booster, a static fire at the launch site is unlikely to be bypassed (SpaceX has never skipped a prelaunch static fire), and would typically occur no fewer than four or five days before launch. As a result, in the somewhat unlikely event that the shutdown stretches beyond the next several days, SpaceX customers SES and GovSat could see their launch delayed, an event that would likely bring financial consequences to the public-private satellite venture.
Looking slightly farther into the future, SpaceX’s flight-proven launch of PAZ and two of its own prototype communications satellites is just about two weeks away from its own static fire test, this time at the West Coast’s Vandenberg Air Force Base. Such an extended shutdown would be utterly unprecedented, but if 2017 and 2018 have done anything at all, they’ve tempered tendencies towards knee-jerk claims of “that’ll never happen!”

Here’s to hoping that Congress can get their act together and return to those they represent the bare minimum of federal stability, for both federal employees and those that depend upon them.
Update: After a solid two days of shutdown, the Senate has apparently reached an agreement to pass a continuing resolution that will maintain funding for another three weeks, after which a new FY2018 budget must be passed to avoid another shutdown. While this thankfully means that the impact to the Space Coast and the Air Force’s 45th Space Wing should be relatively small, I have left my above thoughts on the potential impacts of a longer shutdown untouched for posterity.
Senate has voted on an amended bill to fund U.S. government for 3 weeks. Bill now heads back to the House for debate & vote. If it passes the House without changes, the President then needs to sign it into law. Once all those things happen, the government reopens. Then… 1/2

Tesla confirms that work on Dojo 3 has officially resumed
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo 3,” Elon Musk wrote in a post on X.
Tesla has restarted work on its Dojo 3 initiative, its in-house AI training supercomputer, now that its AI5 chip design has reached a stable stage.
Tesla CEO Elon Musk confirmed the update in a recent post on X.
Tesla’s Dojo 3 initiative restarted
In a post on X, Musk said that with the AI5 chip design now “in good shape,” Tesla will resume work on Dojo 3. He added that Tesla is hiring engineers interested in working on what he expects will become the highest-volume AI chips in the world.
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3. If you’re interested in working on what will be the highest volume chips in the world, send a note to AI_Chips@Tesla.com with 3 bullet points on the toughest technical problems you’ve solved,” Musk wrote in his post on X.
Musk’s comment followed a series of recent posts outlining Tesla’s broader AI chip roadmap. In another update, he stated that Tesla’s AI4 chip alone would achieve self-driving safety levels well above human drivers, AI5 would make vehicles “almost perfect” while significantly enhancing Optimus, and AI6 would be focused on Optimus and data center applications.
Musk then highlighted that AI7/Dojo 3 will be designed to support space-based AI compute.
Tesla’s AI roadmap
Musk’s latest comments helped resolve some confusion that emerged last year about Project Dojo’s future. At the time, Musk stated on X that Tesla was stepping back from Dojo because it did not make sense to split resources across multiple AI chip architectures.
He suggested that clustering large numbers of Tesla AI5 and AI6 chips for training could effectively serve the same purpose as a dedicated Dojo successor. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk wrote at the time.
Musk later reinforced that idea by responding positively to an X post stating that Tesla’s AI6 chip would effectively be the new Dojo. Considering his recent updates on X, however, it appears that Tesla will be using AI7, not AI6, as its dedicated Dojo successor. The CEO did state that Tesla’s AI7, AI8, and AI9 chips will be developed in short, nine-month cycles, so Dojo’s deployment might actually be sooner than expected.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.
