SpaceX's Dragon spacecraft photobombed in orbit by solar eclipse
On December 26th, SpaceX’s second-to-last Cargo Dragon spacecraft was photobombed in orbit by the shadow cast on Earth by a solar eclipse, likely a little over a week before the vehicle is set to reenter the atmosphere and splash down in the Pacific Ocean.
Cargo Dragon lifted off atop a rare new Falcon 9 booster – B1059 – on December 5th, carrying around 2600 kg (5800 lb) of cargo inside on the flight-proven capsules third launch into Earth orbit. After a quick three-day journey from its parking orbit to the International Space Station (ISS), Dragon was successfully captured by the station’s astronauts with a robotic arm and berthed to the orbital outpost, where the crew quickly unloaded its cargo of food, consumables, science, and equipment.
Shortly after liftoff, Falcon 9 B1059 completed its first successful landing – a bit of a surprise ordeal aboard drone ship Of Course I Still Love You (OCISLY) – and the relatively gentle reentry and trajectory should mean that the booster can be turned around almost immediately for its next launch. B1059 is thus a prime candidate for reuse on a future NASA mission and could very well support Cargo Dragon’s next space station resupply mission (CRS-20) as early as March 2020.
For a number of reasons, the spacecraft’s recent success is a touch bittersweet.
Notably, CRS-19 is the second to last orbital mission scheduled for SpaceX’s original Dragon spacecraft, which debuted in orbit in December 2010, becoming the first commercial spacecraft to successfully reenter and be recovered intact. Less than a year and a half later, Cargo Dragon became the world’s first commercial spacecraft to successful rendezvous and berth with the International Space Station (ISS).
The rest, as they say, is history. Five months later, SpaceX launched Cargo Dragon’s first official mission under NASA’s Commercial Resupply Services (CRS) program, known as CRS-1. Aside from a June 2015 launch vehicle failure that prevented Cargo Dragon from reaching orbit on its CRS-7 mission, SpaceX has successfully completed every resupply mission that managed to reach orbit, delivering more than 43 metric tons (95,000 lb) of supplies to the space station and the astronauts aboard it.
There have been several technical challenges over the years but every Cargo Dragon that reached orbit successfully completed its space station resupply mission and was recovered intact from the ocean surface after reentering Earth’s atmosphere. SpaceX has matured and improved almost every aspect of the spacecraft over the nine years it’s been flying, substantially upgrading its PICA-X heat shield, improving navigation sensors, upgrading its reusability, testing Crew Dragon and Starship hardware, and more.
Cargo Dragon has without a doubt been one of SpaceX’s biggest successes, combining with the company’s exceptionally capable and affordable Falcon 9 rocket to enable reliable cargo resupply missions, while also continuing to be the only way that NASA (or anyone alse) can return substantial non-human payloads back to Earth. Thankfully, although the spacecraft’s exceptional track record is set to come to an end after its next launch, the Cargo Dragon lineage will continue to supply the space station in the form of a modified version of Crew Dragon (i.e. Dragon 2).
On December 26th, SpaceX’s CRS-19 Cargo Dragon – attached to the International Space Station (ISS) – was photobombed by the shadow produced on Earth’s surface by an annular solar eclipse. With any luck, the spacecraft’s first upgraded successor will take over and begin orbital resupply launches as early as August 2020, setting SpaceX up for at least another four or so years of Dragon launches.

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.
