SpaceX ‘sleeves’ Starship-derived propellant tank for the first time – here’s why
In a small but important step towards activating a pad capable of launching the largest and most powerful rocket ever built, SpaceX has ‘sleeved’ one of its Starship-derived propellant storage tanks for the first time.
Starship is a fully-reusable, two-stage liquid rocket designed to ultimately cut the cost of orbital launch by at least one magnitude, opening the door for humanity’s sustainable expansion to Earth orbit, the Moon, Mars, and even beyond. To accomplish that lofty feat, it has to be a massive rocket. Measuring approximately 120m (~395 ft) tall and 9m (~30 ft) wide, Starship and Super Heavy will weigh on the order of 300 metric tons (~675,000 lb) when empty.
Once filled to the brim with cryogenic liquid methane (CH4) and liquid oxygen (LOx) propellant and gas, though, a two-stage Starship will easily weigh more than 5000 tons (11 million lb) shortly before and after liftoff. Further, SpaceX wants to be able to launch at least two Starships from Boca Chica in rapid succession. To meet the staggering needs of back-to-back Starship launches, SpaceX has thus had to design and build what will be the world’s largest launch pad tank farm.
Work on that tank farm is already well underway, though progress has been slower than expected. The site’s foundation and a few associated blockhouses were mostly completed by January 2021. By early April, the company had completed the first of at least seven steel propellant storage tanks at its Starship factory and rolled it to the launch pad for installation.
Notably, SpaceX chose to manufacture those storage tanks itself and ended up building structures virtually identical to the tanks that already make up most of flightworthy Starship and Super Heavy airframes. Depending on whether they’re meant to store liquid oxygen or methane, the seven tanks SpaceX is building are either 26 or 30 meters (85 or 100 feet) tall – though the concrete mounts they’re affixed to at the launch site are sized such that all storage tanks will have the same final height.
Of course, being made with the same tools and out of the same steel as Starship and Super Heavy, that means that SpaceX’s custom storage tanks are little more than 4mm (~1/6″) thick steel shells – about as bad as it gets for keeping cryogenic rocket fuel… cryogenic. If SpaceX were to simply use those unmodified tanks, it would be almost impossible to store Starship fuel for more than a few hours – and maybe just a few minutes – without it warming up past the point of usability.
As such, SpaceX’s final Starship tank farm design involves seven Starship-derived storage tanks and seven contractor-built tank sleeves. Measuring around 12m (~40 ft) wide and 40m (~130 ft) tall, those “cryo shells” will enclose all seven SpaceX-built tanks, allowing the company to fill the 1.5m (~5 ft) gap between them with an insulating solid, gas, or some combination of both. With those shells and insulation, SpaceX’s custom-built Starship tank form should be more than capable of storing cryogenic liquid oxygen and methane for days or even weeks.
As of August 5th, SpaceX has installed three of Starship’s custom ground supply equipment (GSE) tanks (with a fourth moved onsite on Thursday), moved two ‘cryo shells’ to temporary storage spots at the pad, and installed one cryo shell that actually turned out to be a million-gallon water tank. On Thursday, SpaceX ‘sleeved’ one of those storage tanks for the first time ever, marking an important milestone towards the activation of a tank farm capable of supporting Starship’s orbital launch debut. Another four sleeves are more or less complete, with the eighth and final sleeve likely just a week or two away from completion.

A fifth GSE tank is also more or less complete, leaving two more to go. However, with some basic math, it’s possible to determine that SpaceX’s orbital launch pad likely only needs five cryogenic tanks (three oxygen, two methane) – and possibly as few as four – to support Starship’s first orbital test flight(s). With SpaceX finally beginning to install tank sleeves, it’s possible that that four or five-tank milestone – and the first tests of SpaceX’s custom, unproven storage solution – are now much closer at hand.
Elon Musk is, in many respects, one of the biggest and most influential figures in modern-day artificial intelligence.
Given that Tesla, SpaceX, and xAI are all looked at in their respective fields as leaders to an extent, each of them has a heavy influence on the future of AI, even though two of them are not thought of, at face value, as AI companies.
Musk has grand expectations for what is to come with AI, not only as a form of assistance to make human lives easier, but to make humans multiplanetary and solve some of the biggest issues that face us today. But even he is astounded by AI’s pace of progress.
He believes that in two years, AI will be so mind-blowing it might be unrecognizable.
Given that AI from 2 years ago feels so old that it should be in a museum, then obviously AI 2 years from now will be mind-blowing https://t.co/TcsKZ8o8OE

This progress can be seen in a variety of ways, but perhaps the most popular way people have shown AI’s progress, especially on social media, is through an incredibly arbitrary way of watching Will Smith eat spaghetti:

This is a great way to show people how AI is improving, especially from a perspective that examines how it can manufacture images and video from prompts. AI is an incredibly complex concept, however, and it goes much deeper than Will Smith eating Italian food.
Musk’s most widely adopted method of AI is likely Tesla Full Self-Driving, which impacts millions of people as they utilize it to increase safety with their travel. Musk has routinely pushed incredibly aggressive timelines for self-driving, especially unsupervised.
Perhaps this perspective is why he feels that things will be solved in a timeframe that is much more aggressive than most of us would think. Regardless, the progress of AI is moving fast, and it seems that Musk’s expectations for it could be high.
But if it can actually achieve full-length motion pictures and even more realistic production value, it will be hard to distinguish between reality and AI very soon.
Tesla just officially confirmed it has built its 10 millionth car, a major milestone for the company that started producing sustainable electric powertrains less than two decades ago.
In that time, Tesla has truly revolutionized the automotive industry, disrupting the idea of what a car should be, how it should be fueled, and how it truly impacts day-to-day life.
10 million vehicles produced globally.

Tesla achieved this feat across four production facilities: the Fremont Factory in Fremont, California, Gigafactory Shanghai in China, Gigafactory Berlin in Germany, and Gigafactory Texas in Austin, Texas.
The 10 millionth vehicle was a Diamond Black Model Y.
Over the course of the past roughly 18 years, Tesla has evolved its lineup from a sporty sedan built on a Lotus body to a lineup of various body styles, performance metrics, and other characteristics that make each one unique.
This is an incredible achievement for a company that is young compared to what it goes up against. When Tesla entered the automotive market, Ford, GM, and Stellantis widely dominated the playing field. Since then, Tesla has caused such a disruption that these three massive brands had to scramble to create EV projects of their own.
Despite their best efforts, they have not been able to match the prowess or the effectiveness of Tesla. They are all reliant on Tesla’s charging infrastructure, their software is inferior, and their self-driving projects are elementary in comparison.
Tesla felt its fair share of growing pains over the years as well. As recent at 2019, there were complaints about build quality, paint quality, and overall luxuriousness. These things have all been improved upon through the company’s maturity, and these strides in quality have led to this 10 million vehicle production achievement, something that other small-and-scrappy EV makers will hope to accomplish one day.
SpaceX just picked up another $1.6 billion from the Pentagon, with the U.S. Space Force awarding two task orders worth $1.6 billion to fly 18 Falcon 9 missions from Vandenberg Space Force Base in California through the end of 2027. The launches will carry satellites for the Space Based Sensing and Targeting portfolio, a set of programs meant to help the military detect and track airborne threats and relay that information across forces in near real time.
The award falls under National Security Space Launch Phase 3 Lane 1, the Space Force’s faster, commercial style procurement track for missions that do not require the military’s most demanding certification process. It is also the largest single order publicly disclosed under that program so far, and the first task order issued since the Space Force nearly tripled Lane 1’s contract ceiling from $5.6 billion to $17 billion on July 17.
SpaceX to become America’s Military data backbone for missiles, drones, and warfighters
Eric Zarybnisky, the Space Force’s acting portfolio acquisition executive for space access, said the entire process, from identifying the requirement to signing the contract, took about two months, including a month set aside for companies to prepare proposals.
SpaceX is not just launching these satellites. It already holds the contracts to build two of the programs within the same portfolio, $4.16 billion for the Space Based Airborne Moving Target Indicator system and $2.29 billion for the Space Data Network Backbone, which Teslarati covered in May. That means SpaceX is now responsible for both building key pieces of the military’s next generation sensing network and getting them into orbit.
With this latest award, SpaceX’s Pentagon contract total for 2026 alone tops $8 billion, adding to a defense portfolio that already includes the Golden Dome missile defense software group SpaceX joined in April and a string of GPS launches it inherited after ULA’s Vulcan rocket ran into a booster anomaly, which we detailed in March.
Lane 1’s vendor pool technically includes seven companies: SpaceX, ULA, Blue Origin, Rocket Lab, Stoke Space, Impulse Space, and Relativity Space. In practice, SpaceX remains the only provider with the combination of launch cadence, flight proven Falcon 9 hardware, and West Coast infrastructure to support a campaign requiring roughly one Vandenberg launch a month for the next year and a half.
Some lawmakers have flagged the growing concentration of national security launches with one company as a risk worth watching. For now, the Space Force keeps backing SpaceX, with it being the company that shows up ready to launch.
