SpaceX's first Space Force launch delayed by coronavirus pandemic
Officials say that SpaceX’s first mission for the Space Force – also the company’s second upgraded GPS III satellite launch – has been significantly delayed by the United States’ growing coronavirus outbreak.
Only recently folded into the Space Force, a Space and Missile Systems Center (SMC) press release discussed the decision in greater detail, confirming that the center itself has chosen to delay SpaceX’s GPS III SV03 launch. Instead of a technical fault or issues processing the rocket or satellite, SMC is delaying the launch to “minimize the potential of COVID-19 exposure to the launch crew and early-orbit operators,” possibly referring to any combination of Lockheed Martin, Raytheon, or SpaceX employees.
This is now the second SpaceX launch to be delayed by the coronavirus pandemic after the Argentinian government’s strict response force its space agency (CONAE) to postpone its SAOCOM 1B Earth observation satellite launch. Viewed a different way, SpaceX’s next two commercial (non-Starlink) launches have each been delayed a month or two. However, it’s reasonable to assume that those delays are more or less indefinite, given that they both appear to be contingent upon the end of the United States’ coronavirus outbreak.
As a result, it’s looking increasingly likely that SpaceX’s next two or three Falcon 9 launches will all be internal Starlink missions, carrying several more batches of 60 communications satellites into orbit. SpaceX’s next Starlink mission – the seventh overall – is expected to launch no earlier than April, likely in the second half of the month. Thanks to SpaceX’s highly successful Starlink factory, at least another two additional batches of satellites are ready or nearly ready for launch, waiting their turn for a Falcon 9 rocket.
SpaceX’s fleet of flight-proven rockets has rapidly diminished after two boosters failed their landing attempts in February and March 2020, making it substantially harder to support an aggressive Starlink launch cadence. Excluding two Falcon Heavy Block 5 side boosters flown in April and June 2019, SpaceX’s fleet is now down to three booster: B1049, B1051, and B1059.
Thankfully, although production slowed down as SpaceX’s Hawthorne factory focus shifted more towards payload fairings and upper stages, the company has continued to build Falcon 9 boosters. Currently, boosters B1058 and B1060 have passed their McGregor, Texas acceptance tests and are awaiting their first launches in Cape Canaveral, Florida. B1058 should become the first SpaceX rocket ever to launch astronauts as early as late May 2020, while B1060 – assigned to launch the GPS III SV03 navigation satellite will now have to wait until June 30th at the earliest for its debut.
Assuming everything goes as planned, both B1058 and B1060 will land shortly after their respective NET May and NET June launches, potentially freeing the boosters up for refurbishment and reflight on future SpaceX missions – Starlink included.
Unfortunately, future launch delays are extremely likely due to the fact that the United States remains in what appears to be the early stages of the coronavirus pandemic. SpaceX itself already has six confirmed COVID-19 cases at its Hawthorne, California factory and headquarters, a number that could easily continue to grow without strict and immediate interventions. For now, though, the company appears set on forging ahead in this time of crisis.

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.

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.
