SpaceX CEO Elon Musk arrives in Texas for milestone Starship engine test
On Saturday evening, SpaceX CEO Elon Musk landed in Waco, Texas – perhaps along with additional SpaceX propulsion engineers – for the critical static fire debut of the first “radically redesigned” Raptor engine, built to power BFR’s Starship upper stage and Super Heavy booster.
If the first operationalized Raptor’s static fire tests go well, there are several possible routes the test program could take, all of which will end up with this engine and several others being tested and ultimately installed on the Starship hopper (Starhopper) prototype under construction roughly 500 miles (800 km) south of SpaceX’s Raptor test cell.

Shortly after Musk revealed official photos of the first operationalized Raptor preparing for an inaugural static fire test at SpaceX’s McGregor, Texas facilities, the SpaceX and Tesla CEO’s private jet was seen landing at Waco, Texas around sunset. Although all SpaceX technical expertise needed for Raptor’s first ignition was probably already on site several days prior, Musk has been known to offer seats on his private planes to SpaceX and Tesla employees when a critical group is needed away from their normal base of operations. The best examples come from Tesla engineering expertise sometimes traveling between Fremont and Gigafactory 1 when needed, often to solve production holdups.
Regardless of whether he was traveling with members of the SpaceX propulsion team, Musk’s arrival at McGregor yesterday signified that Raptor Block 1’s first integrated hot-fire was imminent. Assuming no attempt was made on Saturday night or Sunday morning, SpaceX technicians and engineers are presumably still working on installing what is effectively a new rocket engine and ensuring that Raptor’s test cells – extensively overhauled and upgraded for the occasion – are working as intended. While the development Raptors SpaceX built hovered around 1000 kN (~100t) of thrust, also roughly the same as Merlin 1D, the Raptor now on stand in Texas is reportedly a 200 ton-class engine or more than double the thrust of any single engine SpaceX engineers and technicians have built or test-fired in 15 years of engine development.

A fork in the R&D road
Prior to completing Raptor Block 1 (unofficial designation), SpaceX cumulatively test-fired dev Raptors for far more than 1200 seconds over the course of more than 24 months. It’s unclear how extensively the company’s engineers will be able to test the pathfinder hardware built on the back of that extensive test program. Nominally, one would expect hundreds or thousands of seconds of additional testing to properly characterize the design and production of a brand-new, optimized engine like Raptor while primarily ensuring that it performs within engineering specifications.
Knowing CEO Elon Musk’s self-admitted tendency to push for impractical deadlines and schedules that often appeared rushed for the sake of rushing, it’s not impossible that the first Raptors could find themselves installed on the Boca Chica-based Starhopper test article after Merlin-esque acceptance testing and nothing more. For M1D and MVac, acceptance testing usually takes the shape of a full-duration burn with throttle and gimbal activity to closely simulate a true Falcon 9 or Heavy launch. For the 200-ton Raptor now in Texas, comparable acceptance testing could take a variety of forms, ranging from short Starhopper-relevant burns (10-60 seconds for small hops) to simulating conditions during a Super Heavy launch and landing or even a 6 or 7-minute orbital insertion burn indicative of the performance needed for Starship.
Depending on the interplay between the route SpaceX engineers would likely prefer and the Starhopper test schedule executives and managers might want, this first Raptor engine (and two more soon to follow) could be installed on Starhopper anywhere from a few weeks to several months from now. Elon Musk indicated in early January that he expected hop tests would occur 4-8 weeks later, shortly followed by unplanned damage to the craft’s nose cone that pushed the debut back “a few weeks”.
Aiming for 4 weeks, which probably means 8 weeks, due to unforeseen issues

I just heard. 50 mph winds broke the mooring blocks late last night & fairing was blown over. Will take a few weeks to repair.

Realistically, hop tests should thus be expected to begin no earlier than (NET) 8-12 weeks from the first week of January, translating to NET March or April. This would give SpaceX propulsion engineers a decent amount of time to gain at least a few hundred (or maybe 1000+) seconds of experience operating the newest and most advanced iteration of Raptor.

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.
