SpaceX Starship factory aiming to build five megarockets in 2023
CEO Elon Musk says that SpaceX’s South Texas Starship aims to build up to five of the two-stage megarockets in 2023.
SpaceX’s Boca Chica, Texas hardware endeavors began in an empty field in late 2018, kicking off Starhopper testing in 2019. In late 2019 and early 2020, the company began building the bones of the factory that exists today, relying heavily on several giant tents (“sprung structures”) similar to those used by Tesla. SpaceX has already begun the process of replacing those tents with larger, permanent buildings, but two of the original tents continue to host crucial parts of the Starship manufacturing process.
In terms of useful output, that manufacturing slowed down a bit in 2022. That slowdown can likely be partially explained by the need to move equipment and processes into the first finished section of Starfactory. But in general, SpaceX was simply focused on finishing and testing Starship S24 and Super Heavy B7 – both stages of the latest vehicle meant to attempt Starship’s first orbital launch.
Only by late 2022 did Ship 24 more or less complete proof testing, and Booster 7 is still several major tests away from solidifying full confidence in its design. SpaceX has only conducted limited testing with fully-stacked Starships, further reducing the amount of confidence the company can have in the assembled rocket. Lacking the data needed to know with certainty whether the tweaked designs of Starship and Super Heavy are good enough for several orbital test flights, it’s thus unsurprising that SpaceX only produced a handful of usable ships and boosters in 2022.

But if CEO Elon Musk’s forecast is correct, the company has plans to increase Starbase’s useful output in 2023. According to Musk, SpaceX aims to build “about five full stacks” this year, translating to five flightworthy Starships and five Super Heavy boosters.
In 2022, SpaceX finished Booster 7 and built Booster 8, Booster 9, and most of Booster 10. Booster 8 was almost immediately relegated to the retirement yard. Booster 9, featuring some significant design changes, completed a limited amount of proof testing and returned to the factory in early January – likely for Raptor engine installation. The fate of Booster 10 is unclear, but it stands as a prime example of how fast SpaceX can actually build massive Starship hardware when conditions are right. SpaceX began stacking B10 in late October 2022 and the vehicle is just two stacks away from full height three months later.
In the same period, SpaceX finished and immediately retired Starship S22, finished and began testing Ship 24, finished and began testing Ship 25, and finished stacking Ship 26. Booster 9’s upgrades partially insulate it from the most disappointing possible scenario, retirement before flight. Even if Booster 7 fails during prelaunch testing or its launch attempt, revealing major design flaws, it’s possible that Booster 9’s changes have already addressed those weaknesses, allowing it to continue the flight test campaign. Ship 25’s fate is even more dependent on the fate of Ship 24.
In 2022, SpaceX ultimately produced two “full stacks,” with a third (S26/B10) likely to be completed – albeit with a less certain fate – in early 2023. Delivering five full stacks this year – meaning five ships and five boosters that make it far enough to be paired with another and fully stacked – would be a major improvement. However, as was the case in 2022, higher-volume production will remain a risky proposition until the designs of the vehicles being built have been fully qualified.
Given how long it’s taken SpaceX to partially qualify Super Heavy Booster 7, it appears that the largest source of uncertainty will remain for at least another month or two, if not well into mid-2023. Starship production has many uncertainties of its own, and all of them are complicated by not knowing if a Super Heavy booster will be available to launch each new ship in a timely fashion.
Ultimately, an entirely different constraint means that “five full stacks” may be all SpaceX needs to build for the next 12+ months. After a long and painful process, the FAA completed an environmental review of SpaceX’s Starbase, Texas facilities, permitting a maximum of five orbital (full-stack) Starship launches per year. Starship’s FAA orbital launch license, which has yet to be granted, could be even more restrictive. A second Starship pad under construction in Florida is unlikely to be cleared for orbital launches until Starship has proven itself to be moderately safe in South Texas, which could easily take 12-18 months, if not longer.
Combined with the fact that no super-heavy-lift rocket in history has flown five times in its first year of launch activity, a trend Starship seems unlikely to break, SpaceX could practically halt production entirely in 2023 and still have a full year of testing ahead of it while only using Ships 24-26 and Boosters 7, 9, and 10. Unintuitively, that bodes well for a busy 2023 of Starship test flights, as much of the hardware required for three flight tests is already close to completion or almost ready to begin preflight testing.

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.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.
