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.
Investor's Corner
Musk’s biggest bettor Ron Baron reveals massive SpaceX IPO bet
Renowned investor Ron Baron, founder and CEO of Baron Capital, has once again demonstrated his unwavering faith in Elon Musk’s ventures.
Just after SpaceX’s record-breaking IPO, Baron announced he purchased an additional $1 billion in SpaceX (NASDAQ: SPCX) shares. This move pushes Baron Capital’s total holdings in the company to a staggering $25 billion in market value, underscoring one of the most successful private-to-public investment stories in recent history.
Baron’s relationship with SpaceX dates back to 2017, when his firm began investing approximately $1.75–2 billion through secondary markets and employee tender offers at valuations around $20–22 billion.
By the time of the IPO, which valued SpaceX at over $2 trillion with shares closing near $161, those early stakes had generated more than $13 billion in unrealized gains. Post-IPO, Baron’s position ballooned further, reflecting the company’s meteoric rise driven by reusable rocketry, Starlink’s global satellite internet constellation, Starshield defense applications, and ambitious plans for orbital infrastructure.
In a recent interview, Baron articulated his bullish outlook with characteristic enthusiasm.
Ron Baron said today that he bought $1 billion of @SpaceX IPO shares last Friday, and said that all of Baron Capital’s $SPCX holdings are now worth $25 billion.

“I think we’re going to make hundreds of billions of dollars,” he stated, emphasizing that SpaceX’s achievements in rocketry and satellite technology are “not possible for anyone else to accomplish.” He envisions the company as a cornerstone of humanity’s multi-planetary future, potentially reaching valuations of $10–30 trillion within 10–15 years.
Baron has repeatedly affirmed he has no plans to sell, viewing SpaceX as a “lifetime investment” alongside Tesla.

This conviction stems from SpaceX’s unparalleled execution. The company has revolutionized access to space with Falcon 9 reusability, deployed thousands of Starlink satellites, and is advancing Starship for Mars missions and point-to-point Earth transport.
Baron highlights emerging opportunities like space-based AI data centers and direct-to-cell satellite connectivity, positioning SpaceX at the forefront of a new space economy projected to generate trillions in value.
Critics may question the lofty projections amid high valuations and execution risks, but Baron’s track record speaks volumes. His Tesla holdings, initiated in the mid-2010s, have also delivered outsized returns. As one of the largest institutional holders of SpaceX pre-IPO, Baron Capital’s funds, such as Baron Partners, benefited immensely from valuation markups.
Baron’s $1 billion IPO purchase signals deep confidence in SpaceX’s post-IPO trajectory. In an era of short-term market noise, his strategy exemplifies patient capital: backing visionary leadership and transformative technology.
For investors watching the space sector, it serves as a powerful endorsement that the final frontier may indeed yield the next great wealth-creation engine. As Baron puts it, SpaceX isn’t just building rockets—it’s trying to “save humanity” by expanding our horizons beyond Earth.

SpaceX maintains bold advertising push for Starlink, contrasting Tesla’s minimalistic approach
SpaceX and Tesla, the two flagship companies under Elon Musk’s leadership, share a commitment to groundbreaking technology yet pursue dramatically different paths in how they connect with customers.
Tesla has built its brand through a philosophy of minimal traditional advertising, trusting that exceptional products will generate their own momentum.
SpaceX, by contrast, has embraced high-visibility paid advertising for its Starlink satellite internet service, placing prominent spots during major live sporting events such as the Super Bowl and the recent UFC Freedom 250. This divergence highlights how each company tailors its marketing to the unique demands of its products and target markets.
Tesla’s approach stems directly from Musk’s long-held conviction that superior engineering sells itself. Musk has repeatedly explained that the company redirects resources into research and development rather than endorsements or television commercials.
Tesla’s growth has relied instead on organic channels: enthusiastic owner referrals, viral product reveals like the Cybertruck, extensive media coverage of launches and achievements, and the sheer visibility of its vehicles on roads everywhere.
Even as the company has tested more social media promotions in response to fluctuating demand, its overall strategy remains restrained and digital-focused compared to legacy automakers that pour hundreds of millions into marketing annually.
SpaceX has taken a more assertive route with Starlink to drive widespread consumer awareness. In February of this year, SpaceX aired its first-ever Super Bowl advertisement, marking the initial time any Musk-led enterprise invested in the massive event.
The thirty-second spot emphasized fast and affordable internet available nearly anywhere on the planet, blending inspiring footage of Falcon 9 and Starship landings with narration drawn from science fiction visionary Arthur C. Clarke. United Airlines complemented this with its own Super Bowl commercial showcasing Starlink-enabled high-speed Wi-Fi on flights.

But that is not all SpaceX has done to get word out about its internet service.
Just last night, Starlink branding appeared prominently on the octagon and during the broadcast of UFC Freedom 250, the high-profile event staged on the White House South Lawn. These placements represent a strategic investment in reaching massive, engaged audiences.

The rationale behind SpaceX’s advertising push lies in Starlink’s distinct position as a consumer broadband service. Unlike Tesla’s visually striking cars that act as mobile billboards for early-adopter enthusiasts, Starlink must overcome awareness gaps in rural, remote, and mobile markets where traditional internet infrastructure falls short.
Starlink now serves as SpaceX’s leading revenue generator, with ambitions tied to future growth and potential public offerings. Targeted advertising during sports broadcasts efficiently demonstrates real-world reliability for applications ranging from home connectivity to aviation and live event broadcasting.
Partnerships with airlines and mobile providers further extend its reach, while high-profile placements help convert curiosity into subscriptions amid competition and regulatory considerations.
Ultimately, these contrasting strategies reflect the different maturity levels and competitive landscapes each business navigates. Tesla benefits from built-in visibility and a passionate community that amplifies its message at little cost.
Starlink, operating in the more fragmented broadband sector, requires deliberate efforts to educate and attract mainstream users. By leveraging the spectacle of major sporting events where Tesla once declined to participate, SpaceX is accelerating Starlink toward global ubiquity.
This flexibility underscores a key lesson: even the most innovative companies must adapt their tactics to the practical realities of their markets and customer acquisition challenges.

SpaceX (SPCX) IPO is live today at $135: Here’s exactly what you need to know
SpaceX priced its historic IPO at $135 per share today, raising a record $75 billion.
SpaceX officially priced its initial public offering at $135 per share, offering 555,555,555 shares of Class A common stock and raising $75 billion in what is the largest IPO in stock market history. Shares are set to begin trading on the Nasdaq Global Select Market on Friday, June 12, under the ticker symbol SPCX. The previous record holder was Saudi Aramco’s 2019 offering at $29 billion, followed by Alibaba’s $22 billion offering in 2014.
At $135 per share and roughly 555.6 million shares, the implied valuation sits near $1.75 trillion, which would make SpaceX roughly the seventh largest company in the United States, just above Tesla’s current market cap. Regular investors can request shares at the IPO price through Robinhood, Fidelity, Charles Schwab, SoFi, and E*TRADE, though the deal is heavily oversubscribed and most retail allocations will be partial or unfilled. Once trading opens June 12, anyone with a brokerage account can buy SPCX on the open market.
SpaceX’s amended S-1 is sparking a major Tesla merger conversation
The valuation is anchored primarily by Starlink. Starlink crossed 10 million subscribers as of February 2026 and is adding 750,000 to 1.5 million new users per month, with the connectivity segment already posting a $1.19 billion profit last quarter. The offering also bundles in xAI following SpaceX’s all-stock merger earlier this year, adding Grok and the Colossus supercomputer to the investment thesis. As Teslarati reported, Starlink ended 2025 with $10 billion in revenue, a figure analysts project could reach $24 billion by end of 2026.
Wedbush analyst Dan Ives has been vocal in his support. “I think the time is right,” Ives said, adding that the offering expands the Elon Musk ecosystem rather than competing with Tesla. An average 12-month price target of $165 per share represents roughly 22% upside from the IPO price. Not everyone agrees – Motley Fool noted xAI is spending $1 billion per month playing catch-up to OpenAI and Anthropic.
Musk founded SpaceX in 2002 with a single stated purpose. “Elon founded SpaceX with a goal to change humanity, to make us a multi-planet species,” CFO Bret Johnsen said in the company’s retail roadshow video this week. Musk himself has been more direct: “We are building the systems and technologies necessary to provide global connectivity on Earth and beyond, to understand the true nature of the universe, and to extend the light of consciousness to the stars.”
