SpaceX rocket booster heads west for first California launch in more than a year
For the first time in more than 16 months, a SpaceX Falcon 9 rocket booster has been spotted heading west towards the company’s California pad, a sure sign that the next West Coast launch is just over the horizon.
First spotted in West Texas on August 20th, the Falcon 9 booster – wrapped in a class black plastic cocoon – was captured a second time three days later between Arizona and California. The rocket wrapped up the ~2600 kilometer (~1600 mi) journey from SpaceX’s McGregor, Texas development and test facilities early on August 24th, arriving at the company’s Vandenberg Air Force Base (VAFB) Space Launch Complex 4 (SLC-4) facilities.
At least according to publicly-available launch manifests, the unknown Falcon 9 booster will be spending a fair bit of time in SpaceX’s SLC-4E hangar before its first Californian launch. Still, considering that many misinterpreted a year-old regulatory document as confirmation of SpaceX’s permanent withdrawal from VAFB just earlier this month, a surprise booster arrival is an encouraging sign.
As of now, SpaceX has two or three possible West Coast missions scheduled in the last few months of 2020, but there’s a strong chance that they’ll suffer delays as they near their tentative launch dates. Up first is the joint NASA-ESA Sentinel 6A (Sentinel 6 Michael Freilich, Jason-CS A) ocean topography satellite, one of two new spacecraft meant to continue work done by the Jason-3 spacecraft (launched by SpaceX in 2016). According to a joint review completed on June 25th and referenced in an official document (PDF), SpaceX and NASA are working towards the first Sentinel 6A launch attempt no earlier than (NET) November 10th, 2020.
NASA awarded SpaceX the $97 million launch contract in 2017, all but guaranteeing that Sentinel 6A will fly on a brand new Falcon 9 booster. The fact that the booster spotted in transport over the last week was never seen East of Texas strongly implies that it’s a new Falcon 9 SpaceX tested in McGregor before shipping back to California, in which case Sentinel 6A is almost certainly SpaceX’s next VAFB launch.
In the likely event that the booster that arrived at VAFB on August 24th is unflown, it’s probably Falcon 9 B1063. Germany’s SARah-1 radar imaging satellite is possibly the only other West Coast launch on SpaceX’s manifest that could warrant sending a new booster to California, but recent signs point towards that ~2200 kg (4850 lb) spacecraft launching in Q1 2021 (a delay from Q4 2020) as part of a dedicated SpaceX rideshare mission.
Less likely, SARah-1 could have been manifested on SpaceX’s first dedicated rideshare mission, scheduled to launch in December 2020. Either way, as fairly complex and expensive one-off science spacecraft, both SARah-1 and Sentinel 6A are liable to slip right from their current launch targets, meaning that Falcon 9 B1063 will likely spend at least 2-3 months in storage between now and the start of its first launch flow.
Regardless of the payload or the first stage launching it, SpaceX shipped its former West Coast drone ship landing platform to Florida more than a year ago. Any Falcon 9 booster launching from California will thus have to be expended or land back on land at LZ-4.
While SpaceX and its mystery Falcon 9 booster wait for their next West Coast launch, the company will likely take advantage of the opportunity to familiarize an almost entirely new team of pad and launch engineers and technicians. After its June 2019 Radarsat Constellation Mission launch, SpaceX effectively mothballed its Vandenberg pad and either laid off or transferred the vast majority of employees specific to SLC-4. SpaceX began hiring to rebuild that team in early 2020.
Thanks to a major multi-launch US military contract SpaceX won just a few weeks ago, the company’s Vandenberg facilities are all but guaranteed to remain active – even if only intermittently so – for most of the 2020s.

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.
