SpaceX’s Starship rocket just took a big leap towards orbit with latest test success
A full-scale Starship rocket has passed a critical test for the first time ever, strongly suggesting that the next-generation launch vehicle could be much closer to orbital readiness than most would imagine.
To be clear, a huge amount of work remains before Starship can be deemed anywhere close to its first orbital flight tests, not the least of which is the fabrication and assembly of the first massive Super Heavy booster(s). However, after Starship SN4’s latest successful May 9th test, it’s hard to see any apparent showstoppers that can’t be handled with a combination of fairly routine testing and iterative progress, as well as time and money. There is certainly room for improvement throughout the program but SpaceX has effectively demonstrated that the biggest practical concerns about its approach to Starship are moot.
Captured live on May 9th and 10th by local resident and photographer Mary (bocachicagal) with the help of NASASpaceflight.com, SpaceX worked for about two days to reconfigure its fourth full-scale Starship prototype after two successful Raptor engine static fires and prepare it for a different kind of test. That work mainly involved removing said Raptor and replacing it with a hydraulic ram stand used to simulate the thrust of 1-3 engines without actually needing to perform a static fire test, further allowing SpaceX to simulate much longer engine operations than its spartan test pad could survive. Around 9pm CDT on May 9th (02:00 UTC, May 10), Starship SN4’s latest trial began.
Known as a cryogenic pressure and load test, it differed from a prior “cryo proof test” completed on April 26th, in which Starship was fully loaded with liquid nitrogen (more than twice as cold as dry ice), pressurized to a bit less than 5 bar (~70 psi), and stressed with hydraulic rams. About a week later, after installing a Raptor engine on a full-scale Starship prototype for the first time ever, Starship SN4 fired up said engine on May 5th – another historic first for the next-generation launch vehicle. 30 hours later, SpaceX performed another wet dress rehearsal (WDR) with liquid methane and oxygen and fired up Starship’s Raptor engine again.
After about 48 hours of reconfiguration, SpaceX moved on to a much more serious cryogenic test. As noted by CEO Elon Musk, the 4.9 bar the rocket previously reached was accepted as enough to perform a Raptor static fire test and possibly enough for a low-stress, low-altitude flight test to ~150m (500 ft). For orbital flight, however, Starship needs to withstand a minimum of 6 bar (~90 psi), while 8.5 bar (125 psi) is preferable to give the rocket the 1.4x safety factor optimal for human spaceflight.
This time, SpaceX – having successfully gathered data from two static fire tests and several wet dress rehearsals – was ready to risk Starship SN4 and pressurized it all the way to 7.5 bar (~110 psi). While ~12% shy of minimum human spaceflight standards, Starship SN4 successfully reached and maintained 7.5 bar while the ship stressed with hydraulic rams to simulate the thrust of three Raptor engines, all of which it survived fully intact. What 7.5 bar does offer, however, is a 1.25x safety factor – on the higher end of aerospace industry standards for uncrewed orbital spaceflight (i.e. cargo/satellite launches).
Ready for orbit?
Technically, this means that – pending much additional testing and verification with different serial prototypes and (likely) higher pressures – Starship’s stainless steel structure is effectively qualified for uncrewed orbital launches. Of course, reality is much more complex. To actually perform and survive orbital flights, SpaceX will first need to build and similarly qualify the first Super Heavy boosters and ensure that those unprecedentedly large rockets can survive and sustain ~20-30 Raptor engines firing simultaneously.
Aside from Super Heavy, it’s unknown if SpaceX has begun testing Raptor engines at the durations they will need to burn to booster Starships into orbit (TBD; likely 5-10 minutes of continuous operation). Along those lines, SpaceX also needs to build, test, and qualify Raptor’s vacuum-optimized sibling to complement the sea level version’s smaller, less-efficient nozzle. Still, Musk has already revealed that RaptorVac could be a matter of weeks from its first static fire and rocket engine development – while incredibly challenging – is more of a known quantity for SpaceX.
Perhaps the most important unknown is whether SpaceX’s recent May 2020 WDRs and static fires have used autogenous pressurization, a more efficient method of pressurizing rockets by using hot gas generated by their own engines. It’s extremely likely that SpaceX has been autogenously pressurizing Starship SN4 for its recent tests, but if that weren’t the case, it would be a big source of schedule uncertainty without significant redesign work.
Ultimately, SpaceX appears to have proven that orbital-class rockets can be built cheaply out of commodified steel in extraordinarily spartan production facilities. Many, many challenges remain but the biggest uncertainty and hurdle facing SpaceX’s Starship program and ambitions is well on its way to being fully put to rest.

Pope Leo XIV slams Elon Musk’s pay package due to misinformation (Opinion)
The Pope’s comments seem to be guided by a misunderstanding of what Elon Musk’s pay package entails.
Pope Leo XIV has voiced sharp criticism of corporate pay structures, singling out Tesla CEO Elon Musk and other business leaders as examples of the widening gap between executives and ordinary workers. The pontiff warned that excessive wealth concentration could erode societal values and fuel global polarization.
Pope Leo XIV’s comments seem to be guided by a misunderstanding of what Elon Musk’s pay package entails, and the net positive it would result to TSLA shareholders and the world as a whole.
Pope Leo XIV’s comments
In his first interview since becoming pope in May, Leo XIV, the first US-born head of the Catholic Church, pointed to reports that Musk could become the world’s first trillionaire. As noted in a report from the Financial Times, Pope Leo XIV singled out Elon Musk as an example of the type of wealth that was undermining “the value of human life, of the family, of the value of society.”
“Yesterday, the news (arrived) that Elon Musk is going to be the first trillionaire in the world. What does that mean, and what’s that about? If that is the only thing that has any value any more, then we are in big trouble,” the pontiff stated.
Musk was not the only executive who caught the ire of the leader of the Catholic Church. He noted that while Musk’s pay was problematic, it was only an example of the “continuously wider gap between the income levels of the working class and the money that the wealthiest receive.”
“CEOs that 60 years ago might have been making four to six times what the workers are receiving, the last figure I saw, it’s 600 times what average workers are receiving,” he stated.
Borne out of misrepresentation
A look at Pope Leo XIV’s comments surrounding Elon Musk’s wealth suggests that he may not necessarily be familiar with how the CEO earns his net worth. Musk’s wealth is tied to his stakes in his companies, with a good portion of it coming from Tesla and SpaceX. Thus, quite unlike what the mainstream media narrative might suggest, Elon Musk does not necessarily have a giant vault of gold coins he is hoarding somewhere.
If one were to look at Elon Musk’s pay package, which would result in him becoming a trillionaire, one would see that the CEO could only earn his keep if he proves immense value to Tesla and its shareholders.
His payout might be notable, but he would have to lead Tesla into becoming an $8.5 trillion company first. At this level, Tesla would likely be a notable force of good that would provide a net benefit for people worldwide. Ultimately, it appears that Pope Leo XIV’s comments about Musk may be borne from information gathered only through mainstream sources, some of which tend to have a notable slant against the CEO.

Elon Musk affirms Tesla commitment and grueling work schedule: “Daddy is very much home”
The remarks came as Tesla shares crossed the $400 mark on the stock market.
Tesla CEO Elon Musk reiterated his commitment to the electric vehicle maker and its future projects this week, responding to speculation following his $1 billion purchase of TSLA stock.
The remarks came as Tesla shares crossed the $400 mark on the stock market, extending a rally fueled in part by Musk’s TSLA purchase.
Elon Musk’s nonstop work schedule
Amidst the reaction of TSLA stock to Musk’s $1 billion investment, Tesla owners such as @greggertruck noted that “Daddy’s home.” Musk replied, stating that “Daddy is very much home.” He then shared details of a packed weekend of work, which was definitely grueling but completely within character for a “wartime CEO.”
Musk did note, however, that he had lunch with his kids during the weekend despite his extremely busy schedule.
“Daddy is very much home. Am burning the midnight oil with Optimus engineering on Friday night, then redeye overnight to Austin arriving 5am, wake up to have lunch with my kids and then spend all Saturday afternoon in deep technical reviews for the Tesla AI5 chip design.
“Fly to Colossus II on Monday to walk the whole datacenter floor, review transformers and power production (excellent progress), depart midnight. Then up to 12 hours of back-to-back meetings across all Tesla departments, but with a particular focus on AI/Autopilot, Optimus production plans, and vehicle production/delivery,” Musk wrote in his post.
Wartime CEO
Wedbush analyst Dan Ives described Musk as operating in “wartime CEO mode,” highlighting autonomous driving and AI as a trillion-dollar market opportunity for Tesla. Musk reiterated this point late last month as well, when he outlined the several projects he is juggling among his numerous companies. At the time, Musk stated that he was busy with Starship 10, Grok 5, and Tesla V14. This was despite his notable presence on X.
With Tesla Master Plan Part IV being partly released, the company is entering what could very well be its most ambitious stage to date. To usher in an era of sustainable abundance, Tesla would definitely require a “wartime CEO,” someone who could remain locked in and determined to push through any obstacles to ensure that the company achieves its goals.

Elon Musk confirms cryptic X post was related to SpaceX, not TSLA stock
Musk shared his update in a post on social media platform X.
Elon Musk has confirmed that a cryptic post he shared earlier this month was related to his private sale enterprise, SpaceX, not electric vehicle maker Tesla.
Musk shared his update in a post on social media platform X.
Musk’s cryptic post
Earlier this month, the CEO posted the cryptic words “You’ll Thank Me Later” on X. The post quickly gained attention on social media, as Tesla watchers and Elon Musk fans speculated on what the words could mean. With the announcement that Musk has purchased $1 billion of TSLA stock in the open market, some speculated that the cryptic post was a teaser of sorts to shareholders.
Musk’s massive TSLA purchase was the biggest in history, and it also stood as a notable vote of confidence for the company as it attempts to enter a new era led by robots, AI, and autonomous driving. This was likely one of the reasons why Tesla stock saw a notable rise on Monday’s trading. In another post, however, Musk confirmed that his cryptic post was not in any way related to his stock purchase.
All SpaceX
Considering that all the words in Musk’s post started with an uppercase letter, some space fans immediately speculated that the CEO was teasing something related to SpaceX. The company’s three drone ships, Just Read the Instructions (JRTI), Of Course I Still Love You (OCISLY), and A Shortfall of Gravitas (ASOG), after all, follow similar naming styles.
This was one of the reasons why some TSLA shareholders noted on X that Musk’s post was likely SpaceX-related. In response to one of these comments, Musk stated that these speculations are “Correct.”
The only question now is what exactly Musk was referring to in his post. Perhaps the CEO really was hinting at the name of the drone ship that will be tasked to retrieve Starship in the middle of the ocean.
