SpaceX wins NASA approval to launch astronauts on reused rockets and spacecraft
SpaceX appears to have won NASA’s approval to launch astronauts on reused Falcon 9 rockets and Crew Dragon spacecraft a matter of days after the company’s astronaut launch debut went off without a hitch.
Ever since SpaceX began landing and reusing orbital-class Falcon 9 boosters some 15 months after it won a NASA contract to develop Crew Dragon, the obvious possibility that the two groundbreaking technologies might one day meet has always floated just under the surface. Almost without fail, most joint NASA/SpaceX press conferences will receive a question or two about whether either party is thinking about or working towards astronaut launches on flight-proven spacecraft. Encouraged by the fact that partner Boeing’s separate Starliner spacecraft was sold to NASA with reusability in mind from the start, those questions continued up until (and after) the day SpaceX became the first private company in history to launch astronauts into orbit.
In a wholly unexpected turn of events, a modification to SpaceX’s ~$3.1 billion NASA Commercial Crew Program (CCP) contract was spotted on June 3rd. Without leaving much room for interpretation, the contract tweak states that SpaceX is now “[allowed to reuse] the Falcon 9 launch vehicle and Crew Dragon spacecraft beginning with” its second operational astronaut launch, known as Post Certification Mission-2 (PCM-2) or Crew-2. Given the spectacular, hiccup-free success of SpaceX’s inaugural astronaut launch and International Space Station (ISS) arrival just 3-4 days prior, it’s safe to say that NASA is extremely happy with the results of the mission.
Without a shred of doubt, SpaceX has worked tirelessly for years to earn enough of NASA’s technical trust to permit crewed launches on flight-proven hardware, a possibility that even the optimists in the crowd assumed was distant at best. It has almost always been an uphill battle for SpaceX – a fact made especially clear when framed beside partner Boeing. An inherently conservative organization, NASA has repeatedly given Boeing and its more traditional Starliner spacecraft and development approach the benefit of the doubt while frequently tearing into the nooks and crannies of SpaceX and Crew Dragon over half a decade of cooperation.
While functioning more like an anchor when SpaceX finds itself working with conservative, stubborn organizations like NASA and US military branches, the company’s wholly non-traditional style of development has secured technical success after technical success. Over the course of the second half of SpaceX’s 20-mission NASA Commercial Resupply Services 1 (CRS1) contract, the company has still managed to successfully launch dozens of tons of cargo to the space station with flight-proven spacecraft and boosters. From CRS-11 to CRS-20, five missions featured reused Falcon 9 boosters and all but one of those 10 flights featured once or even twice-flown Cargo Dragon spacecraft.
In short, SpaceX has demonstrated more than a dozen times to NASA that it’s fully capable of building, launching, and reusing orbital-class rockets and spacecraft. Additionally, before an unrelated design flaw destroyed the spacecraft during post-recovery testing, SpaceX successfully launched, recovered, and refurbished Crew Dragon capsule C201 in March 2019, demonstrating its dramatically improved reusability. While suborbital, Crew Dragon C205’s January 2020 In-Flight Abort (IFA) test also likely helped demonstrate the new spacecraft’s reusability and gave NASA more experience with the reuse of Falcon 9 Block 5 rockets as B1046’s fourth launch.
Every step along the way, SpaceX has put its money where its mouth is and proven that it’s more than capable of doing what much larger, more traditional companies have only claimed to be capable of – and often months or even years before its competitors and for hundreds of millions to billions of dollars less. While it’s much more likely that NASA has yet to actually certify SpaceX’s Crew Dragon spacecraft and Falcon 9 boosters for flight-proven astronaut launches, the June 3rd contract modification – at a minimum – signifies the space agency’s expeditious intent to do so. What is unambiguous is the schedule it lays out: SpaceX could potentially launch astronauts on a flight-proven rocket and spacecraft as early as its second operational taxi mission to the ISS.
Known as PCM-2 or Crew-2, the mission is scheduled to follow Crew Dragon’s first operational astronaut launch – Crew-1 – by roughly six months. Contingent upon Crew Dragon Demo-2’s safe return of NASA astronauts Bob Behnken and Doug Hurley later this year, Crew-1 is tentatively scheduled to launch on August 30th, although it could potentially launch even sooner. If successful, Crew-2 should follow as soon as mid-2021 and could potentially reuse Crew-1’s Falcon 9 booster and the Demo-2 or Crew-1 Dragon capsule.

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.
