SpaceX surprises after recovering spacecraft 'trunk' in one piece
In a surprise twist, SpaceX has recovered an expendable ‘trunk’ that launched with Crew Dragon on its January 19th In-Flight Abort (IFA) test, in which the spacecraft successfully escaped from an exploding Falcon 9 rocket.
While recovering pieces of Dragon’s disposable trunk would not have been shocking, SpaceX has returned this particular Crew Dragon trunk to shore in a condition that can only be described as unscathed. The surprise came first on the evening of January 19th, when two separate SpaceX ships returned to Port Canaveral — first and foremost bringing Crew Dragon capsule C205 back to dry land for inspection and possible reuse. However, a separate ship – GO Navigator – followed the ship carrying Crew Dragon not long after, revealing a shockingly intact Dragon trunk on its deck.
At 10:30 am EST (15:30 UTC) on January 19th, Falcon 9 booster B1046, an expendable upper stage, and the newest Crew Dragon spacecraft lifted off from Kennedy Space Center (KSC) Launch Complex 39A (Pad 39A) on the spacecraft’s second-ever integrated launch. Designed to push Crew Dragon’s abort systems to their limits, the spacecraft ignited its SuperDraco thrusters around 85 seconds after liftoff, soaring away from a supersonic Falcon 9 and triggering the rocket’s catastrophic (but expected) explosion around 10 seconds later.
A bit like pushing against a wall, Crew Dragon had to fight uphill against a continuous supersonic blast of air to escape the Falcon 9 rocket that launched it, likely adding tens of thousands of pounds (several dozen metric tons) of additional pressure spread out over the top of the capsule. The spacecraft and its detachable trunk section – carrying a solar array, radiators, and four fins – appeared to survive the experience without issue.
The capsule’s SuperDraco engines shut off after about 10 seconds, leaving the integrated spacecraft to coast to an apogee of ~40 km (25 mi), where it finally detached its trunk (pictured above). Designed to be disposable, Crew Dragon features a trunk functionally similar to the one SpaceX has flown almost 20 times on Cargo Dragon (Dragon 1) missions. Crew Dragon’s trunk looks quite a bit different, stretching taller and featuring an interesting conformal solar array (vs. Dragon 1’s deployable panels), as well as radiators (white rectangular panels) the spacecraft needs to maintain thermal equilibrium while in space.
Nominally, Crew Dragon and Cargo Dragon launch on Falcon 9, reach orbit, and go about their business of delivering astronauts and cargo to and from the International Space Station (ISS). After completing their given mission, the trunk section is eventually detached an hour or two before one last reentry burn, eventually returning the spacecraft to Earth. The trunk is thus left in low Earth orbit (LEO), eventually reentering on its own days, weeks, or months later and vaporizing into plasma before it hits Earth’s surface.
While it’s thus surprising that Crew Dragon C205’s trunk section – built primarily out of carbon composites like Falcon 9’s payload fairing and interstage – survived its In-Flight Abort mission more or less intact, the unexpected recovery sadly doesn’t mean that SpaceX has any plans to try to routinely recover or reuse the hardware. If Dragon trunks detached well before orbit, SpaceX might reconsider, but that would defeat their purpose of providing Dragons with power and thermal management while in orbit.
Surviving a terminal-velocity ocean splashdown is certainly no mean feat, but surviving an orbital-velocity atmospheric reentry is magnitudes more challenging, although SpaceX is certainly cognizant of the trade-off. Starship, for example, is expected to include thermal management and power generation systems as an integral part of the (nominally) fully-reusable spaceship and upper stage. At the scale of Crew Dragon, it’s just hard to rationalize doubling or tripling the mass of the spacecraft’s trunk just to tack on a complex recovery system.
All told, both NASA and SpaceX have since indicated that preliminary telemetry from Crew Dragon’s In-Flight Abort test paints an extremely positive picture and effectively confirmed that the test was a total success. With a little luck, it’s safe to say that Crew Dragon will be sacrificing a trunk section in orbit before returning NASA astronauts to Earth just a few months from now.

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.
