SpaceX’s next Falcon Heavy rocket on track for early 2023 launch
Two weeks after SpaceX’s first Falcon Heavy launch in three and a half years, the US Space Force says that the rocket is on track to launch again “early next year.”
Immediately before and after Falcon Heavy’s first operational launch for the US Space Force, the Space Systems Command confirmed that the massive SpaceX rocket’s next military launch – USSF-67 – was scheduled no earlier than January 2023. The military also confirmed that USSF-67 would reuse two of the three Falcon Heavy boosters that helped launch USSF-44 on November 1st.
Two weeks later, the US Space Force’s tone hasn’t changed, and the Space Systems Command remains confident that Falcon Heavy is on track to launch USSF-67 less than three months after USSF-44.
Assuming the lack of a schedule change is intentional rather than a matter of not checking with SpaceX or other US stakeholders, no change is a good sign. Since the last time the SSC reported that USSF-67 was on track to launch in January 2023, SpaceX successfully launched its fourth Falcon Heavy rocket. USSF-44 was the company’s first launch directly into a geosynchronous orbit ~36,000 kilometers (~22,300 mi) above Earth’s surface.
SpaceX successfully recovered both of Falcon Heavy’s ‘side cores’ and has likely had enough time to thoroughly inspect each booster and begin the refurbishment process. If data gathered from the launch, landing, or recovered boosters uncovered issues with Falcon Heavy’s performance during USSF-44, USSF-67 would almost certainly be delayed. The chances of a delay are magnified by the fact that USSF-67 can’t launch until two of USSF-44’s Falcon Heavy boosters are refurbished and declared ready for a second flight.
But it appears that even a gap of 40 months between Falcon Heavy launches wasn’t enough to make SpaceX falter – at least after working out some prelaunch kinks. SpaceX accomplished a similar feat – launching two Falcon Heavy rockets in less than three months with one pair of side boosters – on the rocket’s second and third launches in April and June 2019. The mission that reused Flight 2’s side boosters was for the US Air Force, so SpaceX and the military already have direct experience tackling those challenges.
In the three and a half years since, SpaceX has gained a huge amount of experience recovering and refurbishing Falcon 9 Block 5 boosters and slashed its record turnaround (the time between two launches of the same booster) from 74 days to 21 days. SpaceX should thus have no issue turning Falcon Heavy side boosters B1064 and B1065 around for a second launch in January 2023, around 60 to 91 after their debut.
While preparing one Falcon Heavy rocket to launch USSF-67 in January, SpaceX – at least according to customer ViaSat – may also be preparing another Falcon Heavy rocket to launch the first ViaSat-3 satellite the same month. Unlike the US Space Force, which recently shipped [PDF] one of USSF-67’s payloads to Florida, ViaSat has yet to ship its first next-generation satellite to the launch site and says that milestone is scheduled for December 2022. That makes a February or March launch much more likely, but ViaSat recently told shareholders that ViaSat-3 remains on track to launch “in the earliest part of” Q1 2023.
Combined, USSF-67 and ViaSat-3 are scheduled to reuse Falcon Heavy side boosters B1064, B1065, B1052, and B1053. Each will use a brand new center core: B1068 for ViaSat-3 and B1079 for USSF-67, according to Next Spaceflight. Like USSF-44, which was the first time SpaceX intentionally expended a Falcon Heavy booster, both new center cores are expected to be expended.
For several reasons, assembling and preparing Falcon Heavy for launch is significantly more time-consuming than Falcon 9, so there will likely be at least a two, three, or even four-week gap between Falcon Heavy’s next two launches. But as long as USSF-67 and ViaSat-3 are ready to fly during narrow windows in early and late January, it appears that SpaceX could launch two Falcon Heavy rockets in one calendar month.
SpaceX has as many as five Falcon Heavy launches scheduled in 2023 – a stark change after more than three years without a single flight.

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.
