SpaceX’s drone ships near return-to-action with Block 5 Falcon 9 landings
Teslarati photographer Pauline Acalin’s recent trips to drone ship Just Read The Instructions’ berth in Port of San Pedro shows that SpaceX technicians are nearly done preparing the hibernating vessel for a return to Falcon 9 rocket recoveries in the Pacific Ocean, a ten-month drought likely to end for good on July 20th.
Although it’s hard to believe, SpaceX’s West Coast autonomous spaceport drone ship (ASDS) has been effectively marooned at its Port of Los Angeles berth for more than nine full months, with the vessel’s last recovery occurring just after the October 9 launch of ten Iridium NEXT satellites, the fourth of five SpaceX Vandenberg launches in 2017 (and the fourth of four West Coast booster landings).

Three months after that October mission and booster recovery, SpaceX expended their next California launch and marked the beginning of a streak of eight missions where flight-proven Block 3 and 4 boosters could have been recovered but no attempts were made. While intermixed with the spectacle of Falcon Heavy’s dual side booster landings at LZ-1, the debut launch and recovery of Falcon 9 Block 5, and two other Block 4 booster recoveries, the majority of SpaceX’s launches since December 2017 have been treated as expendable – put simply, the company decided that recovering and refurbishing twice-flown boosters of older Falcon 9 blocks was not worth the effort and expense.
Instead, those well-worn boosters were expended in the Pacific and Atlantic Oceans after partially supporting a series of experimental tests designed to gather additional data on the recovery envelope of SpaceX’s partially reusable rockets. The rationale makes sense – SpaceX fundamentally sacrificed some of its older, less-reusable Falcon 9 boosters for the sake of knowledge that may allow their highly reusable Falcon 9 Block 5 predecessors a better chance of successfully landing even after exceptionally fast, hot, and high-energy recoveries, a necessity if the upgraded rockets are to be reused 10 to 100 times, as is the goal.
Although Just Read The Instructions spent several months without a full complement of maneuvering thrusters, thanks in part to efforts to keep its besieged East coast sister Of Course I Still Love You operational, photographer Pauline Acalin’s photos over the last several months show that the vessel now has four full thrusters installed and ready to bring it back into rocket recovery action in the Pacific Ocean.

Still, the abrupt return to expendable rocket launches after a year – 2017 – filled to the brim with 18 of 18 successful launches and 14 of 14 successful landings led to a decidedly fascinating vein of disapproval in the SpaceX enthusiast and broader spaceflight fan communities – people had grown accustomed to the adrenaline-soaked thrill of routine Falcon 9 rocket landings. Some expressed worries that regularly and intentionally expending large hunks of metal in the ocean could harm their ecosystems and was tantamount to littering. None the wiser, every other launch provider in the world continues to expend all of their rocket boosters without any attempts at recovery like the nearly all non-Shuttle rocket launches in the past six decades, and their tepidly reusable next-generation rockets are unlikely to even begin attempting hardware recovery until the mid-2020s at the earliest.
Frankly, SpaceX’s abrupt successes with orbital-class rocket recovery struck a chord with observers, demonstrating just how intuitive attempting to recover expensive rocket hardware really is, while also bringing into clear focus the actual insanity of failing to try and of the seemingly ad-hoc rationalization of expendable rocketry. Thankfully, we still have SpaceX, and the company’s spate of rocket booster sacrifices is likely just one expendable launch away from coming to an effective end for the indefinite future, with that particular launch – CRS-15 – scheduled less than two weeks from now, on June 29th.

After CRS-15, which will probably see its twice-flown Block 4 booster expended in the Atlantic, a combination of Block 5 Falcon 9s and Heavies will theoretically bring to an end the practice of expending orbital rocket boosters, at least on SpaceX’s watch. Considering that the upgraded boosters have been designed and built to launch as many as ten times with minimal refurbishment and potentially 100+ times with regular maintenance, the opportunity cost of an expended Block 5 rocket booster is so high that it is difficult to imagine SpaceX will be easily swayed to expend one until it’s flown at least several times prior.
We here at Teslarati eagerly await the imminent demise of expendable rockets, set to begin in earnest – at least for SpaceX – around July 19th and 20th with two Falcon 9 Block 5 launches on two coasts, one with Telstar 19V (Florida) and the other with Iridium-7 (California).

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.
