SpaceX’s first Starship engine suffers “expected” damage during Raptor test fire
SpaceX CEO Elon Musk says that the first full-scale Starship engine to be tested has already been pushed to the point of damage less than three weeks after the campaign began, setting the stage for the second full-scale Raptor to take over in the near future.
According to Musk, while most of the damaged pathfinder Raptor’s components should still be easily reusable, the assembly of the second finalized engine is “almost done” and that Raptor will take over near-term testing rather than waiting for repairs to the first engine. This is undoubtedly an extraordinarily aggressive test program, particularly for such a new and cutting-edge rocket propulsion system, but these latest developments are ultimately far more encouraging than they are concerning.
Merlins. The max chamber pressure run damaged Raptor SN 1 (as expected). A lot of the parts are fine for reuse, but next tests will be with SN 2, which is almost done.

Although the Raptor engine family began integrated subscale static fires way back in September 2016, SpaceX’s propulsion team finalized Raptor’s baseline design and completed assembly, shipment, and an integrated static fire of the first full-scale engine on February 3rd, considerably less than three weeks before Musk took to Twitter. Aside from confirming that the new Raptor had been damaged during its most recent static fire several days prior, Musk indicated that the failure (unsurprisingly) was primarily attributed to the engine reaching the highest chamber pressures yet.
Raptor’s main combustion chamber (the bit directly above the nozzle) has been designed to nominally operate at and reliably withstand extraordinary pressures of 250+ bar (3600+ psi), performance that demands even higher pressures in the components that feed hot methane and oxygen gas into Raptor’s combustion chamber. One prime example hinted at by Musk in a 2018 tweet is its oxygen preburner, used to convert liquid propellant into a high-velocity gas that can then feed a dedicated oxygen turbopump. Aside from the absurdly corrosive environment created by extremely hot gaseous oxygen, the preburner must also survive pressures that could peak as high as 800+ bar, or 12,000 psi.

A lack of technical detail means that it’s hard to know what thrust or main chamber pressure Musk had in mind when referring to exotic alloys that would be needed to survive those pressures, but the performance statistics of a Raptor with a preburner operating at 800+ bar would probably outstrip anything Musk has thus far described. In other words, it’s safe to assume that Raptor has probably not been pushed to those performance levels just yet, although it’s still a distant possibility. More likely is that 800+ bar in the oxygen preburner is an extreme stretch-goal that will take concerted research, development, and optimization to achieve, with Raptor having suffered damage somewhere below those levels while still reaching eye-watering performance figures.

For an engine as complex as Raptor, there are countless dozens of potential failure modes the appearance of which would come as little surprise for an engine just days into full-scale testing. Above all else, the Raptor test schedule held by SpaceX’s world-class propulsion team – be it self-motivated or driven by reckless management-by-spreadsheet – has been fast-paced in the extreme, taking the first high-performance Raptor ever built from standstill to more than 90% thrust and chamber pressures of almost 270 bar (3900 psi) in – quite literally – less than one week. In the same period of time, more than half a dozen static fire tests (ranging from 1-10 seconds) were performed.
Within a few days of that February 10th milestone, in which Raptor reached chamber pressures comparable with the most advanced modern engines (namely RD-180/190/191), the engine was apparently pushed dramatically higher still, reaching a chamber pressure (and thus thrust) that wrought damage on some of the more sensitive parts of the engine’s plumbing. Despite the fact that the second production Raptor is apparently already “almost done”, Musk suggested that it would already feature changes (of unknown gravity) to mitigate the failure modes experienced by Raptor SN01.
SN2 has changes that should help

In an industry where NASA and contractors like Aerojet-Rocketdyne will spend months between static fire tests of Space Shuttle engines that have each literally flown multiple (if not) dozens of missions to orbit and have a demonstrated performance and reliability record that is measured in the hundreds of thousands of seconds, the speed and agility of SpaceX’s Raptor development and test program is breathtaking. What remains to be seen is just how comparably reliable and successful the end results (i.e. operational Raptor) will be, but an attitude that actively accepts and even pursues testing to destruction can ultimately only serve to benefit the finished product at the cost of destroyed hardware and many on-ground lessons learned the hard ways.
Given the immense success of SpaceX’s Merlin family of engines and the aggressive strategy of development and continuous improvement that brought it from Merlin 1A to 1D and MVacD, SpaceX is clearly not fumbling around in the dark when it comes to Raptor R&D.

Elon Musk calls out $2 trillion SpaceX IPO valuation as ‘BS’
In a swift rebuke on X, Elon Musk dismissed reports claiming SpaceX had confidentially filed for an initial public offering targeting a valuation above $2 trillion, labeling the information as unreliable.
Elon Musk is quick to call out any false information regarding him or his companies on his social media platform, known as X.
A recent report that claimed SpaceX was aiming to go public with an IPO in the coming weeks at a massive valuation of $2 trillion was called out by Musk, who referred to it as “BS.”
In a swift rebuke on X, Elon Musk dismissed reports claiming SpaceX had confidentially filed for an initial public offering targeting a valuation above $2 trillion, labeling the information as unreliable.
The exchange highlights ongoing media speculation about the rocket company’s future and Musk’s frustration with what he views as inaccurate financial reporting. The report came from Bloomberg.
Don’t believe everything you read.
Bloomberg publishes bs.
— Elon Musk (@elonmusk) April 3, 2026
The controversy erupted on April 2, 2026, when influencer Mario Nawfal amplified claims from Bloomberg.
The outlet posted that SpaceX had boosted its IPO target valuation above $2 trillion, describing it as potentially one of the largest public offerings in history. Musk challenged the story.
It echoes past instances where Musk has corrected valuation rumors about his companies, emphasizing that speculation often outpaces reality.
Background context adds nuance.
Earlier reports indicated SpaceX had filed confidential IPO paperwork with the U.S. Securities and Exchange Commission, potentially positioning it for a record-breaking debut that could eclipse Saudi Aramco’s 2019 listing.
Initial estimates pegged a possible valuation north of $1.75 trillion, building on a post-merger figure around $1.25 trillion after SpaceX absorbed xAI. A subsequent Bloomberg update claimed advisers were floating figures above $2 trillion to investors, with the offering potentially raising up to $75 billion.
SpaceX remains a private powerhouse. Its achievements include thousands of Starlink satellites providing global broadband, routine Falcon 9 rocket reusability, and a mission to slash launch costs, along with ambitions for Starship to enable Mars colonization.
The company also benefits from government contracts with NASA and the Department of Defense. A public listing could democratize access for retail investors while subjecting SpaceX to greater scrutiny and quarterly reporting pressures.
Critics of the reports point to the confidential nature of filings, which limits verifiable details. Musk has previously downplayed inflated valuations, once calling an $800 billion figure for SpaceX “too high.”
Supporters argue that hype around mega-IPOs, especially amid the ongoing AI fervor, fuels premature narratives that distract from core technical milestones, such as full Starship reusability and Starlink constellation expansion.
The incident reflects broader tensions in tech finance. Anonymous sourcing in valuation stories can drive market chatter and betting activity, yet it risks misinformation.
Bloomberg defended its reporting through multiple articles citing “people familiar with the matter,” but Musk’s blunt dismissal resonated widely on X, with users piling on to question media reliability.
Whether SpaceX ultimately goes public remains uncertain. Musk has teased an IPO tied to Starlink maturity, but priorities center on engineering breakthroughs over Wall Street timelines. For now, the $2 trillion figure joins a list of rumored milestones that Musk insists should be taken with skepticism.

Elon Musk reveals date of SpaceX Starship v3’s maiden voyage
The announcement arrives after Flight 11 on October 13 of last year, which concluded a busy 2025 testing campaign. Since then, SpaceX has focused on ground testing, including cryoproofing of Ship 39 and preparations for Booster 19, the first V3 Super Heavy.
SpaceX CEO Elon Musk has revealed the timeline for the next Starship launch. It will be the first launch using SpaceX’s revamped design for Starship, as its v3 rocket will take its maiden voyage sooner than many might expect.
Musk announced on April 3 on X that the next Starship flight test, and the first flight of the upgraded v3 ship and booster, is 4 to 6 weeks away. The update signals the end of a nearly six-month hiatus since the program’s last launch.
Elon says the first V3 Starship launch will occur in 4-6 weeks
It will be the first Starship launch since Flight 11 on October 13, 2025 https://t.co/QnnYPTdbUu
— TESLARATI (@Teslarati) April 3, 2026
The upcoming mission, designated as Starship’s 12 integrated flight test (IFT-12), marks a significant milestone. It will be the debut of the v3 configuration, featuring a taller Super Heavy Booster and Starship upper stage. The changes SpaceX has made with the v3 rocket and booster are an increased propellant capacity and the more powerful Raptor 3 engines.
Earlier predictions from Musk in March had pointed to an April timeframe, but the latest timeline now targets a launch window in early to mid-May 2026.
The V3 iteration represents a substantial evolution from previous Starship prototypes. Engineers have optimized the design for improved manufacturability, higher thrust, and greater efficiency. Raptor 3 engines deliver significantly more power while reducing weight and production costs compared to earlier variants.
With these enhancements, SpaceX aims to boost payload capacity toward 200 metric tons to low Earth orbit in a fully reusable configuration — a dramatic leap from the roughly 35-ton target of prior versions. Such capabilities are critical for ambitious goals, including NASA’s Artemis lunar missions and eventual crewed flights to Mars.
The announcement arrives after Flight 11 on October 13 of last year, which concluded a busy 2025 testing campaign. Since then, SpaceX has focused on ground testing, including cryoproofing of Ship 39 and preparations for Booster 19, the first V3 Super Heavy.
Recent activities have involved static fires, activation of the new Pad 2 at Starbase in Boca Chica, Texas, and integration of Raptor 3 engines.
A prior incident with an early V3 booster on the test stand in late 2025 contributed to the delay, necessitating additional assembly and qualification work.
Musk’s timeline updates have become a hallmark of the Starship program, often described with characteristic optimism.
SpaceX’s Starship V3 is almost ready and it will change space travel forever
While past targets have occasionally shifted by weeks, the rapid iteration pace remains impressive. However, don’t be surprised if this timeline shifts again, as Musk has been overly optimistic in the past with not only launches, but products under his other companies, too.
SpaceX continues to refine launch infrastructure, including new propellant loading systems and tower mechanisms designed to support higher cadence operations. A successful V3 flight could pave the way for more frequent tests, tower catches of both booster and ship, and progression toward operational reusability.
The v3 debut is viewed as a transition point for Starship, moving beyond experimental flights toward a system capable of supporting large-scale deployment of Starlink satellites, lunar landers, and interplanetary transport.
Success on IFT-12 would demonstrate not only the new hardware’s performance but also SpaceX’s ability to recover from setbacks and maintain momentum.
As the 4-to-6-week countdown begins, anticipation builds at Starbase. Teams are finalizing vehicle stacking, conducting final pre-flight checks, and preparing for regulatory approvals. The world will be watching to see if Starship V3 can deliver on its promise of transforming humanity’s access to space.

SpaceX to launch military missile tracking satellites through new Space Force contract
SpaceX wins a $178.5M Space Force contract to launch missile tracking satellites starting in 2027.
The U.S. Space Force awarded SpaceX a $178.5 million task order on April 1, 2026 to launch missile tracking satellites for the Space Development Agency. The contract, designated SDA-4, covers two Falcon 9 launches beginning in Q3 2027, one from Cape Canaveral Space Force Station in Florida and one from Vandenberg Space Force Base in California. The satellites, built by Sierra Space, are designed to bolster the nation’s ability to detect and track missile threats from orbit.
The award falls under the National Security Space Launch Phase 3 Lane 1 program, which Space Force uses to move payloads to orbit on faster timelines and at more competitive prices. “Our Lane 1 contract affords us the flexibility to deliver satellites for our customers, like SDA, more easily and faster than ever before to all the orbits our satellites need to reach,” said Col. Matt Flahive, SSC’s system program director for Launch Acquisition, in the official press release.
SpaceX is quietly becoming the U.S. Military’s only reliable rocket
The SDA-4 contract is the latest in a long string of national security wins for SpaceX. As Teslarati reported last month, the Space Force recently shifted a GPS III satellite launch from ULA’s Vulcan rocket to SpaceX’s Falcon 9 after a significant Vulcan booster anomaly grounded ULA’s military missions indefinitely. That move made it four consecutive GPS III satellites transferred to SpaceX after contracts were originally awarded to its competitor.
This didn’t come without a fight and dates back years. SpaceX originally had to sue the Air Force in 2014 for the right to compete for national security launches, at a time when United Launch Alliance held a near monopoly on the market. Since then, the company has steadily displaced ULA as the dominant provider, and last year the Space Force confirmed SpaceX would handle approximately 60 percent of all Phase 3 launches through 2032, worth close to $6 billion.
With missile defense satellites now part of its launch manifest alongside GPS, communications, and reconnaissance payloads, SpaceX is giving hungry investors something to chew on before its imminent IPO.
