SpaceX is building launch pad tanks out of Starship parts and that’s a big deal

SpaceX has begun installing the first of numerous propellant storage tanks at its first orbital South Texas launch facilities – a mostly ordinary and expected step made extraordinary by the fact that those tanks will be built out of Starship parts.

Labeled “GSE” for Ground Support Equipment, the first signs of those self-built storage tanks began appearing at SpaceX’s Boca Chica Starship factory less than two months ago in mid-February. A matter of weeks later, the first of those SpaceX-brand cryogenic storage tanks is off to the launch site for installation (and insulation) while at least two more tanks are well on their way to completion.

While a few ground starge tanks may look like a distraction in the scope of a program tasked with building the world’s largest (and fully reusable) rocket, the existence of those tanks is far more significant than it might initially appear.

Simply put, rocket propellant storage – even for extremely cold cryogenic liquids like those that SpaceX uses – is a thoroughly solved problem. Numerous commercial vendors exist and industrial demand for practically identical tanks is far higher, further lowering commercial tank costs even for those with niche use-cases thanks to economies of scale. For SpaceX’s purposes, major discounts could like be secured given that the company would need to purchase around three to four-dozen commercial-off-the-shelf (COTS) 100,000 gallon tanks to supply a launch pad with enough commodities for two back-to-back launches of Starship and Super Heavy.

That initial launch capability – which SpaceX appears to be working towards – would likely allow the company to start orbital refueling test flights (and Starlink launches, perhaps) immediately after completion. However, that initial capability wouldn’t suffice for ambitious missions to Mars, the Moon, or higher Earth orbits; where one Starship would need to be rapidly refueled with 3-10+ tanker launches. A launch facility capable of supporting 5-10 back-to-back launches (optimally just a few hours apart) would require many times more propellant storage.

The point is that for the initial target of two (or so) launches between commodity resupply, SpaceX could likely acquire the few dozen new storage tanks it would need for a few million dollars apiece for a total cost likely between $50M and $100M. Instead, SpaceX has decided to design and build its own propellant storage tanks. Even more significantly, the GSE tanks SpaceX has already begun building appear to be virtually identical to Starships.

In other words, SpaceX is effectively taking identical rocket parts, slightly tweaking a handful of those parts, and turning what could have been a rocket into a propellant storage tank. This is significant because relative to all other rockets in history, even including SpaceX’s own Falcon 9 and Heavy, building storage tanks with unchanged rocket parts on a rocket assembly line would be roughly akin to hiring Vincent van Gogh to paint lane lines.

Ever since Elon Musk made the radical decision to switch from composite structures to stainless steel, Starship has always aimed to be radically different than any large rocket before it. Crucially, by using commodity steel, the CEO imagined SpaceX would be able to build Starships fairly easily and for pennies on the dollar next to even SpaceX’s exceptionally affordable Falcon 9. In the last 18 months, it’s become apparent that SpaceX has built a factory capable of churning out one or two massive steel rockets per month and is willing to consign at least four or five of those Starship prototypes to all-but-guaranteed failures for the sake of data-gathering and iterative improvement.

Technically, the most logical conclusion would be that Musk was right and that SpaceX has quickly developed the ability to build steel rockets larger than any other launch vehicle on Earth for perhaps just $5M or less apiece. However, SpaceX is also raising on the order of $1-2B in venture capital annually, so they could technically afford to shoulder the cost of extremely expensive Starship prototypes if the company was confident that there was a path to cut those costs and reach the targets needed for the rocket to make economical sense.

Now, the existence of self-built propellant storage tanks virtually identical to flightworthy Starship airframes all but guarantees that SpaceX is already building Starships for a few million dollars each – and possibly much less. More than a year ago, Musk said that SpaceX was already building the Raptor engines that will power Starship and Super Heavy for less than $1M apiece and was working to mass-produce a simpler variant for less than $250,000. Beyond engines and primary structures, Starship hardware is fairly simple and ranges from Tesla-derived motors, basic flaps, and landing legs to off-the-shelf pressure vessels (COPVs) and wiring. SpaceX has managed that extraordinary cost-efficiency despite the fact that Boca Chica is still nowhere close to the level of volume production Musk is aiming for, meaning that there are still far more efficiencies waiting to be realized.

GSE-2 – a second storage tank – is just two stacks and a week or two of work away from following GSE-1 to the launch pad. (NASASpaceflight – bocachicagal)

For now, with virtually no retooling and the exact same assembly line, SpaceX’s South Texas rocket factory is busy churning out massive launch pad tanks – one of which is already preparing for installation while another two speed towards completion. All told, SpaceX appears to be preparing foundations for seven 9m-wide (30ft), 27.5m-tall (90ft) Starship-derived tanks that should be capable of storing ~2200 tons (4.9 million pounds) of subcooled liquid methane in three tanks and ~7300 tons (16.1 million pounds) of liquid oxygen in the other four tanks – enough for two orbital Starship launches.

Tesla CEO Elon Musk says flying cars are coming

Published

Tesla CEO Elon Musk said that flying cars will be coming to the market, something that his own company has hinted at previously.

Musk said on X, in response to a post that read, “We were promised flying cars and all we got is infinite superintelligence for everyone,” “You will get flying cars.”

The post rang back to when Musk teased flying and hovering capabilities for the Tesla Roadster, the company’s supercar that has been delayed more times than anyone cares to count. It was set for an unveiling earlier this year, but it was then pushed back to August. There is still no sign of it coming.

However, that does not mean it won’t. But one of the biggest features of the Roadster that was teased was a SpaceX package that featured cold gas thrusters on the rear end that would help with white-knuckle acceleration. Another set would face the ground and would help the Roadster gain small bits of altitude, potentially helpful to jump over obstacles.

Elon Musk hints at Tesla Roadster’s “hovering” abilities in SpaceX package

But it is not a straightforward thing for Musk. As a serial entrepreneur, he tends to spend his time on major disruptors; currently, his largest projects are artificial intelligence and compute power, as well as SpaceX’s launches that will eventually make life multiplanetary.

In the past, he has been critical of flying cars and has been in favor of tunnels, one of the big reasons he started the Boring Company. In 2017 at a TED talk, he said:

“There is a challenge with flying cars in that they’ll be quite noisy. The wind force generated will be very high. Let’s just say that if something’s flying over your head, if there are a whole bunch of flying cars all over the place, that is not an anxiety-reducing situation…You’re thinking, ‘Did they service their hubcap? Or is it going to come off and guillotine me as they’re flying past?'”

However, he’s never been against them. He has also said he’s in favor of both tunnels and flying cars.

Most recently, Musk said that anyone who wants a flying car should be able to get one. This was stated last October on the Joe Rogan Experience:

“My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars… I think if Peter wants a flying car, we should be able to buy one.”

Whether the Roadster will be Tesla’s flying car or potentially another one remains in the mind of Musk. Of course, the Roadster will have to make its way to production lines before we find out.

SpaceX’s next trillion dollar bet has nothing to do with rockets, Musk tells staff

Elon Musk told SpaceX staff AI revenue will soon dwarf rockets and Starlink combined entirely.

Elon Musk told SpaceX employees this week that artificial intelligence, not rockets, will soon carry the company’s revenue. In a roughly 29 minute internal address posted on SpaceX’s X account on Tuesday, Musk said AI revenue will pass every other line of business at SpaceX “probably in September” and pull further ahead by the fourth quarter.

The numbers he gave are specific. SpaceX currently runs 1.4 gigawatts of AI compute capacity. Musk wants that at 10 gigawatts by the end of 2027, a jump he tied directly to revenue: “if we bring 10GW of AI online by the end of next year, it will be $300 billion to $500 billion a year in revenue.” He called those “big numbers,” which undersells a projection larger than what most countries produce in a year.

Musk went further on where AI fits into SpaceX’s future. “Probably in four or five years, AI will be 99% of the value of SpaceX,” he told staff, adding that digital intelligence would eventually run “a trillion times” ahead of biological intelligence as computing scales. He tied that growth to the company’s founding mission, telling employees “we must win on AI, because the future is overwhelmingly AI and robots,” with the payoff meant to help fund Starship and a Mars program that increasingly runs through Terafab, the joint Tesla, SpaceX and xAI chip plant.

None of this is entirely new territory. SpaceX told investors much the same story during its first earnings call as a public company on August 4, where Musk moved the company’s $1 trillion revenue target up a year to 2030 and said Starlink could someday carry a majority of the world’s internet. What the all hands video adds is a hard deadline and a specific power figure Musk had not given publicly before, along with a franker pitch to his own workforce that AI, not launch cadence, is now the thing SpaceX is betting its future on.

The AI revenue itself is not coming from SpaceX training its own models. It is largely Starlink acting as the network layer for xAI’s workloads, plus SpaceX renting out compute capacity directly, the same approach behind the roughly $16 billion the company spent on AI infrastructure in a single quarter.

Musk closed the video with a pitch aimed at recruiting and retention rather than investors, telling employees that anyone who helps SpaceX win the AI race will eventually get the chance to go to the moon or Mars themselves. Whether SpaceX can turn 1.4 gigawatts into 10 in seventeen months is the more immediate question, and one that will show up in quarterly numbers well before anyone leaves Earth.

Tesla has one big financial question to answer for investors: Morgan Stanley

In a new note to investors on Tuesday, Morgan Stanley analyst Andrew Percoco said that Tesla has one big financial question to answer for investors regarding its Robotaxi rollout, Full Self-Driving software, and Optimus.

Percoco said in the note that, for the most part, investors are still very positive about the direction the company is headed. However, there are some things the firm would like to see, and they have to do with financials.

Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue

Tesla bulls are more than convinced that the company’s Full Self-Driving software is proof it can develop physical AI. Financially, however, there are still some questions, especially on elevated spending, which CEO Elon Musk said would occur as the company works to roll out Robotaxi faster and continue developing its Optimus robot.

The latter two are where Tesla will have to prove progress to investors, as Percoco writes that both projects “will require clearer evidence that Robotaxi is scaling and more tangible Optimus proof points to support the ROI on elevated capex.”

Percoco said the second quarter earnings call did not change his long-term thesis of where Tesla is positioned in the AI race, which is out in front. However, there are concerns that weaker gross margins and higher R&D spend will stress financials, and that has “sharpened our (and investors’) focus on measurable progress across Robotaxi and Optimus.”

Additionally, Robotaxi still needs to be proven with more operation in existing cities while maintaining safety but improving how many rides it gives in any given time, he said. For Optimus, Percoco wrote that he is “still looking for evidence beyond commentary around SOP.”

Morgan Stanley put Percoco in charge of covering Tesla after long-time analyst Adam Jonas transitioned to the automotive side.

Currently, Morgan Stanley has a $415 price target on Tesla and a ‘Hold’ rating on the stock. It is trading at around $330 at the time of publication, which was 2:30 P.M. on the East Coast.
