SpaceX competitor Blue Origin touts 25-reuse future rocket as R&D continues
A spokesperson for Blue Origin, the reusable rocket company funded by Jeff Bezos and one of the only serious prospective SpaceX competitors, reiterated an oft-used claim that its orbital New Glenn rocket has been designed with reusability in mind “from the start” and stated that the vehicle’s booster is expected to fly 25 times, while its BE-4 engines can expect to see as many as 100 reuses.
Ariane Cornell, Blue Origin’s head of business development and strategy, provided her comments as part of a satellite and rocket hardware panel at the Hong Kong-hosted CASBAA 2018 conference, mainly focused on major participants in the Asian satellite broadcasting industry, for which SpaceX has launched a number of satellites with several more soon to come.
Correction from Ariane: New Glenn first stage can do 25 missions, BE-4 engines designed for 100 flights each.

While scarcely anything has changed in the last 12 months, that in itself is hugely noteworthy – SpaceX remains almost completely unchallenged in the space launch industry, at least in terms of investing in R&D for the purpose of dramatically decreasing the cost of orbital launches. While they have yet to dramatically cut the customer-side prices of Falcon 9 and Falcon Heavy launches, it’s all but guaranteed that the sustainable ability to do so is not only already in place but improving day by day. Every flight-proven SpaceX launch completed even before Falcon 9 Block 5’s takeover likely provides as much as tens of millions of dollars for the company to either reinvest or recoup investments in reusability and Falcon Heavy, among other things.

As of today, Blue Origin is quite simply the only rocket company with demonstrated successes, resources, and commitment to serious operationally-reusable rockets – while Blue has yet to reach orbit, commercial launch stalwarts ULA, Arianespace, and ILS have functionally buried their heads in the sand and either have no plans at all or plan flying even their tepid, disinterested steps into reusable rocket hardware by the mid-2020s at the absolute earliest. SpaceX, on the other hand, has already launched its first purpose-built reusable rocket – Falcon 9 Block 5 – and has two or three more completed boosters either at their launch sites or nearing shipment, with many more being prepared in their Hawthorne, CA factory. In fact, SpaceX’s final non-Block 5 mission is in less than four days (June 29), after which all future launches will be transferred to Block 5 rockets.
All future SpaceX missions will be conducted with highly reusable rocket boosters in the middle of 2018, whereas SpaceX’s current operational competitors are essentially not even trying to field competitive reusable rocket hardware on operational launches before 2024 or 2025. Blue Origin, on the other hand, still appears to be committed to completing the development of its huge, reusable New Glenn rocket, an orbital launch vehicle currently aiming for a debut launch sometime in late 2020. While still late to the start of the SpaceX-fueled reusable launch revolution, commercial launches with reusable hardware beginning as early as 2020-2021 bodes extremely well for Blue’s ability to actually carve out a sturdy segment of the market, while also giving SpaceX at least a decent hint of external motivation to remain competitive.

Aside from Blue Origin and a respectable effort from China, also aiming for initial reusable launch vehicle testing in 2020 (albeit beginning with a conservative – but still orbital – subscale prototype), all other commercial launch competitors are effectively betting their livelihoods on the failures non-traditional launch providers like SpaceX, betting that reusable rockets fail to appreciably lower costs to customers over the better part of the next decade. SpaceX, meanwhile, will begin putting those bets to the test in as few as three weeks.

Tesla confirms that work on Dojo 3 has officially resumed
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo 3,” Elon Musk wrote in a post on X.
Tesla has restarted work on its Dojo 3 initiative, its in-house AI training supercomputer, now that its AI5 chip design has reached a stable stage.
Tesla CEO Elon Musk confirmed the update in a recent post on X.
Tesla’s Dojo 3 initiative restarted
In a post on X, Musk said that with the AI5 chip design now “in good shape,” Tesla will resume work on Dojo 3. He added that Tesla is hiring engineers interested in working on what he expects will become the highest-volume AI chips in the world.
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3. If you’re interested in working on what will be the highest volume chips in the world, send a note to AI_Chips@Tesla.com with 3 bullet points on the toughest technical problems you’ve solved,” Musk wrote in his post on X.
Musk’s comment followed a series of recent posts outlining Tesla’s broader AI chip roadmap. In another update, he stated that Tesla’s AI4 chip alone would achieve self-driving safety levels well above human drivers, AI5 would make vehicles “almost perfect” while significantly enhancing Optimus, and AI6 would be focused on Optimus and data center applications.
Musk then highlighted that AI7/Dojo 3 will be designed to support space-based AI compute.
Tesla’s AI roadmap
Musk’s latest comments helped resolve some confusion that emerged last year about Project Dojo’s future. At the time, Musk stated on X that Tesla was stepping back from Dojo because it did not make sense to split resources across multiple AI chip architectures.
He suggested that clustering large numbers of Tesla AI5 and AI6 chips for training could effectively serve the same purpose as a dedicated Dojo successor. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk wrote at the time.
Musk later reinforced that idea by responding positively to an X post stating that Tesla’s AI6 chip would effectively be the new Dojo. Considering his recent updates on X, however, it appears that Tesla will be using AI7, not AI6, as its dedicated Dojo successor. The CEO did state that Tesla’s AI7, AI8, and AI9 chips will be developed in short, nine-month cycles, so Dojo’s deployment might actually be sooner than expected.

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.
