SpaceX’s Mr Steven gains upgraded arms to catch its first Falcon 9 fairings
SpaceX’s iconic Falcon 9 payload fairing recovery ship, known as Mr Steven, has been spotted in California’s Port of San Pedro having new arms installed with two cranes and a crew of SpaceX technicians. Aside from the sudden addition of dramatically different arm design, a large inflatable structure also took shape – seemingly overnight – right behind Mr Steven, the purpose of which is entirely unclear.
Incredibly, these massive new arms and their new equally large support struts and base plates have begun installation barely two weeks after Mr Steven took roost and had his old arms removed at SpaceX’s Berth 240 property. While the timeline of the arm and net upgrades – mentioned by CEO Elon Musk several weeks ago – was previously uncertain, the incredibly quick turnaround from old arm removal to new arm install suggests that SpaceX may, in fact, be aiming to have Mr Steven ready for recovery operations as early as Iridium-7, scheduled for launch on July 20th. In all likelihood, the fairing recovery vessel will be held up till the subsequent Vandenberg Air Force Base launch while a net with an area perhaps four times larger is custom-built for SpaceX.

Nevertheless, SpaceX’s speed rarely fails to surprise, and it’s entirely possible that a new, larger net was already ordered some time ago in preparation for the eventuality that Mr Steven’s first recovery mechanism was unsuccessful. Given the fact that at least two main arms and perhaps eight white, cylindrical struts have apparently been completed and are awaiting installation at Berth 240, it’s probable that the lead time on this new recovery mechanism stretches back at least several months, likely at least a month before Musk mentioned that Mr Steven would have its usable catching area grown “by a factor of [four]” in early June.
Yup, we are extending the net area by a factor of 4

Closing the fairing recovery gap
With four times the net available to catch wayward Falcon 9 payload fairings, SpaceX may be able to finally close the gap between Mr Steven and the successful and routine recovery and reuse of the second of three main Falcon 9 (and Heavy) components. At roughly 10% of the total cost (not price) of a single-booster Falcon 9, the considerable effort being put into the recovery of carbon-composite payload fairings is in a way motivated more by manufacturing bottlenecks than by the money it will save SpaceX (somewhat less than $3m per half).

SpaceX’s team of composite technicians and engineers will need to reliably fabricate as many as ~50 payload fairing halves in 2018, effectively one half each week
By recovering payload fairings before they touch the ocean surface, the company may – in one fell swoop – be able to dramatically reduce the operational expenditure required to sustain the annual production of dozens of Falcon fairings, each of which requires an inescapable and tediously slow stint in a massive autoclave, only a few of which can be squeeze into the company’s Hawthorne factory. As an example, SpaceX’s team of roughly 150 dedicated composite technicians and engineers will need to reliably fabricate as many as ~50 payload fairing halves – nearly a full half each week – to sustain SpaceX’s anticipated 2018 manifest of 24-28 launches, excluding three Cargo Dragon resupply missions that don’t need fairings.
While both Crew and Cargo Dragon spacecraft and trunks contain a large proportion of carbon fiber-composite structures, every composite Falcon 9 interstage that rolled off of the assembly line since February 2018 is part of a Block 5 booster and is thus expected to support a bare minimum of several missions on its own, functionally multiplying the useful output of any given production line even while the amount of work (and thus work-hours) is reduced. While Falcon 9 boosters – making up roughly 70% of the cost of the entire rocket – have been successfully upgraded to support several reuses each, SpaceX still has to produce a new payload fairing and upper stage for each launch. A spectacular Block 4 farewell earlier this month – complete with a recoverable booster expended to make way for Block 5 – simply served to emphasize the company’s desire to mitigate the expandability of both (currently) unreusable segments of Falcon 9.

- Arm installation will presumably continue over the course of the week, hopefully reaching completion in time to recovery Iridium-7’s payload fairing. (Pauline Acalin)
If Mr Steven can recover even a small fraction – say 25% – of SpaceX payload fairings launched annually, the exact same level of effort (and thus capital) could support 25% more launches annually or reduce the work hours spent on fairing production by 25%. As it happens, SpaceX’s next-generation rocket (BFR) happens to be built (theoretically) almost entirely out of carbon-composites, from the propellant tanks to the spaceship’s delta wing.
Originally meant to focus on the wholly unexpected appearance of a giant inflatable structure at Berth 240, SpaceX’s breakneck pace of action abruptly recentered it on the equally unexpected installation of one the vessel’s first upgraded arms, meant to support a net that could be as much as four times larger than its predecessor. That symbolism on its own is a worthy representation of some of the best aspects of SpaceX’s world-class team of engineers and technicians, acting as a slightly more on-topic corollary to the equally rapid design, prototyping, fabrication, and testing of ad-hoc ‘submarines’ intended to help a number of Thai children currently trapped in a cave near the country’s border with Myanmar/Burma.

Elon Musk’s xAI gains first access to Saudi supercluster with 600k Nvidia GPUs
The facility will deploy roughly 600,000 Nvidia GPUs, making it one of the world’s most notable superclusters.
A Saudi-backed developer is moving forward with one of the world’s largest AI data centers, and Elon Musk’s xAI will be its first customer. The project, unveiled at the U.S.–Saudi Investment Forum in Washington, D.C., is being built by Humain, a company supported by Saudi Arabia’s Public Investment Fund.
The facility will deploy roughly 600,000 Nvidia GPUs, making it one of the world’s most notable superclusters.
xAI secures priority access
Nvidia CEO Jensen Huang stated that the planned data center marks a major leap not just for the region but for the global AI ecosystem as a whole. Huang joked about the sheer capacity of the build, emphasizing how unusual it is for a startup to receive infrastructure of such magnitude. The facility is designed to deliver 500 megawatts of Nvidia GPU power, placing it among the world’s largest AI-focused installations, as noted in a Benzinga report.
“We worked together to get this company started and off the ground and just got an incredible customer with Elon. Could you imagine a startup company, approximately $0 billion in revenues, now going to build a data center for Elon? 500 megawatts is gigantic. This company is off the charts right away,” Huang said.
Global Chipmakers Join Multi-Vendor Buildout To Enhance Compute Diversity
While Nvidia GPUs serve as the backbone of the first phase, Humain is preparing a diversified hardware stack. AMD will supply its Instinct MI450 accelerators, which could draw up to 1 gigawatt of power by 2030 as deployments ramp. Qualcomm will also contribute AI200 and AI250 data center processors, accounting for an additional 200 megawatts of compute capacity. Cisco will support the networking and infrastructure layer, helping knit the multi-chip architecture together.
Apart from confirming that xAI will be the upcoming supercluster’s first customer, Musk also joked about the rapid scaling needed to train increasingly large AI models. He joked that a theoretical expansion one thousand times larger of the upcoming supercluster “would be 8 bazillion, trillion dollars,” highlighting the playful exaggeration he often brings to discussions around extreme compute demand.

Elon Musk debunks pay package and lip reader claims in double takedown
Musk’s quick debunks highlighted once more that X is an ideal platform for directly countering misinformation.
Elon Musk recently took to X to debunk some misinformation about his 2025 CEO performance award, as well as some comments he made during Donald Trump’s banquet in honor of Saudi Prince Mohammed bin Salman.
Musk’s quick debunks highlighted once more that X is an ideal platform for directly countering misinformation.
Musk’s pay package
Elon Musk’s 2025 CEO performance award was created as a path for him to gain a 25% stake in Tesla. It would also make him a trillionaire, provided that he manages to meet all of the performance award’s aggressive targets. This has not stopped critics from running with the apparent narrative that Musk will be getting the $1 trillion with utmost certainty, however.
This included the More Perfect Union account on X, which noted that “Elon Musk is set to make more than every U.S. elementary school teacher combined, according to the Washington Post.”
Musk responded to the pro-union amount’s post, highlighting that he has not earned any of his $2025 performance award so far. Musk also noted that those who believe he will be getting $1 trillion should invest in TSLA stock, as his compensation is tied to the company’s performance and growth. Investors who hold their TSLA until Musk achieves his full pay package would likely get notable returns.
Lip reader fail
Musk also debunked claims from the Daily Mail, which claimed that he made an “explosive” remark at Trump’s banquet for Saudi Prince Mohammed bin Salman. Citing observations from lip reader Nicola Hickling, the Mail claimed that Musk asked Pfizer CEO Albert Bourla, “What is your opinion, is he a terrorist?” The publication also posted a video of Musk allegedly making the risqué comment on X.
Musk proceeded to correct the publication, stating that the lip reader’s observations were fake. Instead of asking the Pfizer CEO if the Saudi Prince was a terrorist, Musk noted that he was asking the executive about cancer medicine. “False, I was asking about upcoming cancer drugs,” Musk wrote in a response on X.
Musk’s comments resulted in numerous critical responses to the Mail’s video, with some X users joking that the lip reader who analyzed the clip should probably get a visual acuity test, or a better training course on lip reading at least.

Tesla Diner to transition to full-service restaurant as Chef heads for new venture
“I am leaving the Tesla Diner project to focus on the opening of Mish, my long-desired Jewish deli. Projects like Mish and the Tesla Diner require a sharpness of focus and attention, and my focus and attention is now squarely on Mish.”
Tesla Diner, the all-in-one Supercharging and dining experience located in Los Angeles, will transition to a full-service restaurant in January, staff said, as Chef Eric Greenspan said he would take on a new project.
A report from the Los Angeles Times says Greenspan confirmed through a text that he would leave the Diner and focus on the opening of his new Jewish deli, Mish.
Greenspan confirmed to the paper:
“I am leaving the Tesla Diner project to focus on the opening of Mish, my long-desired Jewish deli. Projects like Mish and the Tesla Diner require a sharpness of focus and attention, and my focus and attention is now squarely on Mish.”
Greenspan took on the job at the Tesla Diner and curated the menu back in March, focusing on locally-sourced ingredients and items that would play on various company products, like Cybertruck-shaped boxes that hold burgers.
Tesla Cybertruck leftovers are the main course at the Supercharger Diner
The Tesla Diner has operated as somewhat of a self-serve establishment, where Tesla owners can order directly from their vehicles through the center touchscreen. It was not exclusive to Tesla owners. Guests could also enter and order at a counter, and pick up their food, before sitting at a booth or table.
However, the report indicates Tesla is planning to push it toward a sit-down restaurant, full of waiters, waitresses, and servers, all of which will come to a table after you are seated, take your order, and serve your food.
It will be more of a full-featured restaurant experience moving forward, which is an interesting move from the company, but it also sounds as if it could be testing for an expansion.
We know that Tesla is already considering expanding locations, as it will be heading to new areas of the country. CEO Elon Musk has said that Tesla will be considering locations in Palo Alto near the company’s Engineering HQ, and in Austin, where its HQ and Gigafactory Texas are located.
Musk said that the Diner has been very successful in its first few months of operation.
