SpaceX first orbital spacecraft set to smash reusability record on last launch
The first orbital spacecraft designed and built by SpaceX is set to smash a reusability record on its 20th and final International Space Station (ISS) resupply launch, hopefully ending an exceptional career with yet another noteworthy achievement.
After a rocket-related hardware issue forced a four-day delay, a flight-proven Cargo Dragon spacecraft and Falcon 9 rocket are set to lift off no earlier than (NET) 11:50 pm EST, March 6th (04:50 UTC, March 7th) on NASA’s 20th and final SpaceX Commercial Resupply Services (CRS-20) mission. Although SpaceX’s final CRS1 launch, 20th mission milestone, flight-proven Dragon, and fairly quick Falcon 9 booster turnaround are all significant and exciting in their own ways, the most noteworthy technical aspect of CRS-20 can be found in the Dragon capsule that will soon be perched atop the tip of the rocket.
Shared on March 1st alongside confirmation of a successful Falcon 9 wet dress rehearsal (WDR) and static fire at its Cape Canaveral, Florida Launch Complex 40 (LC-40) pad, SpaceX revealed that Cargo Dragon capsule C112 (C1: Dragon 1; 12: capsule #12) will be supporting CRS-20 as early as this Friday. If all goes according to plan, it will be the spacecraft’s third cargo mission to the ISS since February 2017, becoming the third orbital SpaceX vehicle to do so. Even more significantly, C112 is poised to crush Cargo Dragon’s own previous record for the shortest time between two orbital launches.
Back in June 2017, SpaceX became the first private company in history to successfully reuse an orbital-class spacecraft on its CRS-11 Cargo Dragon mission, itself the first private spacecraft in history to successfully rendezvous with the space station. Since then, all but one CRS mission has featured an orbit-proven Dragon capsule, making CRS-20 the ninth time SpaceX will attempt to launch a spacecraft into orbit for the second (or third) time.
In other words, nearly half of all of SpaceX’s NASA CRS missions have featured flight-proven spacecraft, while several have also launched with flight-proven Falcon 9 boosters. Still, while extremely impressive that SpaceX has managed to convince the risk-averse space agency to fly several dozen tons of critical hardware on flight-proven rockets and spacecraft, Cargo Dragon capsule reuse has always been a comparatively lengthy and complex process.
Back in July 2017, just a month after SpaceX’s first successful Cargo Dragon reuse, CEO Elon Musk offered some insight into the capability’s potential value.
“Musk said he expects the next Dragon reuse and all future reuses to save SpaceX nearly 50% of the cost of manufacturing an entirely new spacecraft. Musk admitted that the first refurbishment of Dragon likely ended up costing as much or more than a new vehicle, but this is to be expected for the first attempt to reuse any sort of space hardware that must survive some form of reentry heating and saltwater immersion.”

Ultimately, SpaceX has almost certainly realized Musk’s ambition of cutting the cost of orbital space station resupply missions in half (at least). Scheduled to launch on March 6th, Cargo Dragon capsule C112 last launched in December 2018, reentering Earth’s atmosphere and splashing down on January 13th, 2019. With CRS-20, the capsule could thus crush the previous record – 19 months – by more than 25%. Measured from splashdown to the capsule’s shipment to the launch pad, SpaceX may have spent less than a year refurbishing the Cargo Dragon spacecraft, likely more than a 50% improvement over all past refurbishment operations.
CRS-20 should thus mark a climactic and fitting end to Cargo Dragon 1’s nine-year spaceflight career. While bittersweet that the spacecraft and its many siblings will likely never fly again, Musk has said that Dragon 2 (Crew Dragon) – the spacecraft intended to replace it – is dramatically easier (and thus cheaper) to reuse than Dragon 1. As such, SpaceX should have no issue continuing its trend of lowering the cost of access to space after it begins space station cargo deliveries under its CRS2 NASA contract later this year.

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.
