SpaceX Starship passed “cryo proof” test for the first time and here’s what’s next
Elon Musk says a SpaceX Starship prototype has passed a critical “cryo proof” test for the first time, opening the door for the rocket to move on to even bigger tests.
Late on April 26th, SpaceX’s South Texas team (and possibly a console team in California) readied the fourth full-scale Starship prototype (SN4) for its second major test. Known as a cryogenic proof test, it began less than 24 hours after the rocket completed a room-temperature gas pressure test to check for leaks and verify that the pressure vessel was sound. Musk quickly confirmed that Starship SN4 passed through that “ambient proof test” without issue.
For the cryo proof test, room-temperature nitrogen gas was replaced with ultra-cold liquid nitrogen, serving as a chemically neutral (i.e. non-explosive) simulant for Starship’s liquid oxygen and methane propellant. After a few hours of partial loading and offloading cycles meant to ensure that Starship’s valves and propellant supply hardware was working as intended, SpaceX controllers fully filled the rocket with some ~1000 metric tons (2.2 million lb) of liquid nitrogen. Once full, a hydraulic ram setup was activated to exert forces akin to Raptor engines operating at full thrust. After several prior failures, Starship SN4 thus became the first to survive the ordeal and graduate into the next stage of testing.
According to CEO Elon Musk, that next step will be a static fire test with a lone Raptor engine installed. Able to produce at least 200 metric tons of thrust (~450,000 lbf) at full throttle, Raptor is an exceptionally efficient methalox (methane/oxygen) rocket engine designed by SpaceX to power Starship and its Super Heavy booster. Methane and oxygen was chosen in large part because of the relative potential ease of its extraction and refinement on Mars.
Per Musk, that static fire could occur within the next six or so days, meaning that SpaceX will likely install a functional Raptor engine on a full-scale Starship for the first time ever within the next day or two. Before a static fire can be performed, though, another significant test or two will have to be completed.
Known as a wet dress rehearsal (WDR), the first of those tests will be similar to April 26th’s cryo proof but with the neutral liquid nitrogen placed by real liquid oxygen and methane propellant. This is much riskier than the cryo proof in the sense that if a tank failure were to occur or a fire to accidentally start, 1000+ tons of highly-pressurized propellant could easily create a massive explosion and fireball, destroying or damaging much of the surrounding pad equipment. The WDR could potentially be rolled into another Raptor engine test that would verify its preburner performance.


To operate, Raptors first take liquid oxygen and liquid methane into separate parts of the engine and rapidly heat them to turn them into high temperature gas. Those preburners then send that hot gas to separate turbopumps that spin up and allow the engines to keep supplying themselves with large quantities of propellant, followed by the process of actually igniting the engine itself with a complex series of blowtorches.
If the preburner and turbopump spin-up test is successful, SpaceX can then move on to the actual static fire. Featuring a single Raptor engine, Starship SN4 will hopefully become the first full-scale rocket to safely operate a flight-grade engine since SpaceX began full-scale tests in November 2019. If successful, that static fire could pave the way for Starship SN4 to perform a Starhopper-style 150m (500 ft) hop test as early as May 2020 – a hop that would be powered by a single Raptor engine according to Musk.
Starship SN5 will reportedly be the first ship to both have a nosecone installed and three Raptor engines installed if SN4 has a very successful few weeks and that new ship is perhaps just 5-10 days from being fully assembled. In short, things are about to get very busy and very exciting at SpaceX’s South Texas Starship factory and launch pad.

SpaceX and Google mull massive partnership on Musk’s orbital data dream: report
The two companies are currently in talks for a rocket launch deal to support the placement of data centers in orbit as part of their push into space-based computing.
SpaceX and Google are in the process of ironing out the details of a potential partnership, a new report from the Wall Street Journal says. The two companies are currently in talks for a rocket launch deal to support the placement of data centers in orbit as part of their push into space-based computing.
In a move that blends cutting-edge AI demands with the final frontier of space exploration, Google is in exclusive talks with Elon Musk’s SpaceX for a rocket launch deal to deploy data centers in orbit. The Wall Street Journal is now reporting today, May 12, that the discussions mark Google’s aggressive expansion into space-based computing, addressing the exploding energy needs of artificial intelligence that terrestrial infrastructure can no longer sustain.

SpaceX, nor Google, have commented on the report.
The catalyst for a potential deal is clear: AI’s voracious appetite for electricity. Global data centers consumed about 415 terawatt-hours (TWh) of electricity in 2024—roughly 1.5 percent of worldwide usage—according to the International Energy Agency. That figure is projected to more than double to around 945 TWh by 2030, with AI-focused servers growing at 30 percent annually, outpacing overall electricity demand growth by more than four times.
Some forecasts peg data center consumption exceeding 1,000 TWh by 2026, equivalent to Japan’s entire national electricity use. A single large AI training facility can draw as much power as 100,000 homes. On Earth, this translates to grid overloads, skyrocketing costs, land shortages, and massive water demands for cooling—constraints that threaten to throttle AI progress.
Orbital data centers promise a radical workaround. In space, satellites can harness constant, unobstructed sunlight for power—solar panels generate roughly five times more energy in orbit than on the ground, with no night cycle or atmospheric interference.
Excess heat radiates harmlessly into the vacuum of space, eliminating energy-intensive cooling systems and water usage. No terrestrial land or power grid is required, freeing operations from regulatory and environmental bottlenecks.
Musk has long championed the concept, framing it as inevitable. “Space-based AI is obviously the only way to scale,” he wrote on SpaceX’s site following the xAI merger. “Global electricity demand for AI simply cannot be met with terrestrial solutions… In the long term, space-based AI is obviously the only way to scale.”
He has repeatedly highlighted solar advantages: “Space has the advantage that it’s always sunny,” and “any given solar panel is going to give you about five times more power in space than on the ground.”
Musk predicted in early 2026 that “in 36 months but probably closer to 30 months, the most economically compelling place to put AI will be space,” adding that within five years, annual space-launched AI compute could surpass Earth’s cumulative total. “SpaceX will be doing this,” he declared when discussing scaled-up Starlink satellites with high-speed laser links for orbital data transfer.
Meanwhile, Google has been quietly advancing a similar vision under Project Suncatcher, its internal “moonshot” initiative. CEO Sundar Pichai has described plans to launch two prototype satellites equipped with Tensor Processing Units (TPUs) by early 2027 for testing thermal management and reliability in orbit. In interviews, Pichai has called orbital computing a potential “normal way to build data centers” within a decade, enabled by launch cost reductions.
SpaceX is uniquely positioned to make this reality. The company recently filed with the FCC to launch up to one million satellites dedicated to orbital data centers at altitudes between 500 and 2,000 kilometers, projecting capacity for 100 gigawatts of AI compute.
These talks align with SpaceX’s broader ambitions, including a potential IPO where orbital infrastructure features prominently in investor pitches.

Challenges remain formidable, as is expected with a project with expectations so lofty. Radiation-hardened hardware, laser-based inter-satellite and Earth-downlink communications, launch economics, and orbital debris management are key hurdles.
Yet early movers like Starcloud (which trained the first large language model in orbit in late 2025) and Google’s prototypes signal accelerating momentum. Rivals, including Amazon and Blue Origin, are exploring similar paths, but SpaceX’s Starship and Starlink heritage give it a launch cadence edge.
This partnership could redefine AI infrastructure, turning the skies into the next data center frontier. As Earth’s power limits loom, Musk’s vision, combined with Google’s ambition, could position space not as sci-fi, but as the scalable solution for humanity’s computational future.
Investor's Corner
Legendary investor Ron Baron says Tesla and SpaceX stock buys will continue
In a wide-ranging appearance on CNBC’s Squawk Box on May 12, legendary investor Ron Baron, founder, CEO, and portfolio manager of Baron Capital, reaffirmed his deep conviction in Elon Musk’s two flagship companies.
Legendary investor Ron Baron says he will continue buying stock of both Tesla and SpaceX, as he continues his support behind CEO Elon Musk, who he says is a special person and “brilliant.”
In a wide-ranging appearance on CNBC’s Squawk Box on May 12, legendary investor Ron Baron, founder, CEO, and portfolio manager of Baron Capital, reaffirmed his deep conviction in Elon Musk’s two flagship companies.
With assets under management approaching $55–56 billion, Baron detailed his firm’s substantial holdings, outlined plans for the anticipated SpaceX IPO, and painted an exceptionally optimistic picture for both Tesla (NASDAQ: TSLA) and SpaceX, framing them as generational opportunities that will reshape industries and deliver extraordinary long-term returns.
Baron Capital’s position in SpaceX has grown dramatically since the firm began investing around 2017. What started as roughly $1.7 billion has ballooned to more than $15 billion, making it the firm’s largest holding.
Tesla ranks second, valued at approximately $5 billion in the portfolio. Together with stakes in xAI and related Musk-led ventures, these investments account for roughly one-third of Baron Capital’s $60 billion in lifetime profits since 1992. Baron emphasized that the growth stems from Musk’s singular ability to execute ambitious visions—from reusable rockets to global satellite internet and beyond.
The centerpiece of the discussion was SpaceX’s expected initial public offering, targeted for mid-2026 following a confidential S-1 filing. Baron announced plans to purchase an additional $1 billion in shares at the IPO.
Ron Baron said today that he plans on buying an additional $1 billion of SpaceX stock during the upcoming IPO:
“At the IPO price, I’ve got an order for $1 billion. I want to buy more stock at the IPO. I don’t know if we’re going to get filled, but we’re going to try. I believe… pic.twitter.com/KOv1HvYcZ0

He described the company’s trajectory in sweeping terms: “This is going to become the largest company on the planet.”
He highlighted Starlink’s expansion of high-speed internet to every corner of the globe, the revolutionary economics of reusable rockets, and Starship’s potential to enable massive space-based data centers and interplanetary infrastructure.
Baron sees SpaceX not merely as a rocket company but as a platform poised for exponential scaling once it goes public, with post-IPO appreciation potentially reaching 10- to 20- or even 30-times current levels over the next decade or more.
On Tesla, Baron struck an equally enthusiastic note, declaring that “now is Tesla’s moment.” He projected the stock could reach $2,000 to $2,500 per share within 10 years—implying a market capitalization near $8.3 trillion and roughly 5–6 times upside from recent levels. While Tesla remains a major holding, Baron’s optimism centers on its evolution beyond electric vehicles into an AI, robotics, autonomous-driving, and energy platform.
He pointed to robotaxis, Full Self-Driving (FSD) technology, Optimus humanoid robots, energy storage, and the vast real-world data advantage from Tesla’s global fleet as catalysts that will fundamentally alter the company’s revenue model and valuation multiples. Baron views these developments as transformative, shifting Tesla from a traditional automaker to a high-margin technology and infrastructure powerhouse.
Throughout the interview, Baron’s admiration for Musk was unmistakable. He has likened the entrepreneur to a modern Leonardo da Vinci for his artistic, multidisciplinary approach to solving humanity’s biggest challenges.
Baron’s personal commitment mirrors this confidence: he has repeatedly stated he does not expect to sell a single share of his own Tesla or SpaceX holdings in his lifetime, positioning himself as the “last one out” after his clients. This stance underscores a philosophy of patient, long-term ownership rather than short-term trading.
Baron’s comments arrive at a time of heightened anticipation around SpaceX’s public debut, which could rank among the largest IPOs in history and potentially value the company at $1.5–2 trillion or more at listing.
For investors, his message is clear: the Musk ecosystem—spanning electric vehicles, autonomy, robotics, satellite communications, and space exploration—represents one of the most compelling secular growth stories of the era. While short-term volatility in tech and EV stocks may persist, Baron sees these as buying opportunities for those who share his multi-decade horizon.
In summarizing his outlook, Baron reinforced that the combination of technological breakthroughs, massive addressable markets, and Musk’s leadership creates asymmetric upside that few other investments can match.
For Baron Capital’s clients and long-term Tesla and SpaceX shareholders alike, the investor’s latest CNBC remarks serve as both validation and a call to remain patient through the inevitable ups and downs. As Baron sees it, the best days for both companies—and the returns they can deliver—are still ahead.

Trump’s invite for Elon just reshuffled Tesla’s big Signature Delivery Event
Tesla rescheduled its final Model S farewell to May 20 after Musk joined Trump in China.
Tesla has rescheduled its Model S and Model X Signature Edition delivery event to Wednesday, May 20, 2026, after abruptly calling off the original May 12 celebration. The event will take place at Tesla’s factory at 45500 Fremont Boulevard in Fremont, California, the same location where the Model S first rolled off the line in 2012. Invitees received a follow-up email asking them to reconfirm attendance and download a new QR code ticket, with Tesla noting that all travel and accommodation expenses remain the buyer’s responsibility.
The reason behind the original cancellation came into focus the same day it was announced. President Trump invited Elon Musk, Apple’s Tim Cook, BlackRock’s Larry Fink, Boeing’s Kelly Ortberg, and executives from Goldman Sachs, Blackstone, Citigroup, and Meta to join his trip to China this week for a summit with President Xi Jinping. The agenda covers trade, artificial intelligence, export controls, Taiwan, and the Iran war, following weeks of escalating friction between Washington and Beijing over AI technology, sanctions, and rare earth exports. Trump wrote on Truth Social, “I am very much looking forward to my trip to China, an amazing Country, with a Leader, President Xi, respected by all.”
Tesla launches 200mph Model S “Gold” Signature in invite-only purchase
The vehicles at the center of all this are the last Model S and Model X units Tesla will ever build. Priced at $159,420 each, the 250 Model S and 100 Model X Signature Edition units come finished in Garnet Red with a one-year no-resale agreement, giving Tesla right of first refusal if the owner decides to sell. As Teslarati reported, the Model S defined Tesla’s early identity as a serious luxury automaker, and the Fremont factory line that built it is now being converted to manufacture Optimus humanoid robots.
Musk’s inclusion in the China delegation drew attention given his very public relationship with Trump, and the invitation signals the two have moved past and past grievances. Trump originally brought Musk on to lead the Department of Government Efficiency following his inauguration, and despite a sharp public dispute in mid-2025, the two have appeared together repeatedly in recent months. A seat on the China trip, the most diplomatically consequential visit of Trump’s current term, puts Musk back at the table on U.S. economic policy at a moment when Tesla’s China revenue remains one of the company’s most important financial pillars.
