SpaceX’s orbital Starship launch pad tank farm comes to life for the first time
Update: Two days after a bevy of tanker trucks began to arrive at SpaceX’s orbital Starship launch site with load upon load of cryogenic liquid nitrogen, the company’s custom-built tank farm appears to have taken its very first ‘breaths.’
In other words, at least one of seven massive propellant storage tanks – two of which appear to have been fully completed and insulated – began venting. For a tank like SpaceX’s ground support equipment (GSE) tanks, the level of venting observed can only mean one thing: pressure maintenance during operations with cryogenic fluids. As cryofluids are loaded into empty tanks, they inevitably come into contact with warm pipes and tank walls, rapidly warming a portion of the liquid that then boils into gas. Tanks then need to vent that excess gas to avoid bursting.
In the case of SpaceX’s two completed liquid oxygen GSE tanks and a spate of liquid nitrogen (LN2) deliveries this week, it’s clear that the company has begun the process of testing and activating part of its brand new orbital-class Starship tank farm – beginning with much less risky LN2 proof testing. Filling the two finished LOx tanks with LN2 should also serve the dual purpose of flushing and cleaning them of any debris or contaminants, ensuring that it’s safe to fill them with LOx when the time comes.
For the first time, SpaceX appears to have begun delivering large quantities of cryogenic fluids to Starship’s orbital launch pad – still under construction but fast approaching some level of initial operational capability.
Sometime in the morning on September 19th, a semi-truck carrying a cryogenic liquid nitrogen (LN2) transport trailer arrived at SpaceX’s Starbase launch facilities. Normally, that would be a completely mundane, uninteresting event: SpaceX has used and will continue to use liquid nitrogen to safely proof test Starship prototypes and supercool their liquid methane (LCH4) and oxygen (LOx) propellant for the indefinite future. However, up to now, 100% of all Starbase cryogen deliveries have gone to the suborbital launch site, where two “mounts” and a few concrete aprons have supported all Starship and Super Heavy tests and launches to date.
Instead, this particular LN2 tanker headed for Starbase’s first orbital tank farm and began to offload its cryogenic liquid cargo at a number of brand new fill stations specifically designed for the task.
Still well under construction and at least a few weeks or months from total complete, Starship’s orbital launch site tank farm will ultimately be a group of eight massive storage tanks surrounded by thousands of feet of insulated plumbing, industrial pumps, a small army of “cryocoolers,” a blockhouse filled with human-sized valves, and much more. Said tank farm has been under construction for the better part of 2021, beginning with work on its concrete foundation this January.
Nine months later, the orbital tank farm is nearly complete. A power distribution and communications blockhouse has been complete for weeks with virtually all the wiring and cabling needed for the orbital launch mount and tower already in place. Several hundred feet of concrete cable and plumbing conduit have been filled with thousands of feet of wires, cables, and pipes and been sealed and buried. The tank farm blockhouse – where a dozen or so massive valves control the flow of propellant to and from the orbital launch mount and tower – is complete save for some final plumbing.
Finally, seven of eight GSE (ground support equipment) tanks have been installed and partially plumbed. Built in the same factory, six are virtually identical to Starship and Super Heavy tanks and will store LOx (3x), LN2 (2x), LCH4 (2x), and around a million gallons of water. Save for one LCH4 tank, all have been installed at the farm and that last tank (known as GSE8) is nearly complete back at the build site. Additionally, to insulate those seven thin, steel storage tanks, SpaceX has contracted with a water/storage tank company to build seven “cryoshells” and said million-gallon water tank.
The water tank was installed months ago and all seven shells are completed and ready to go as of last month. Only two of those seven cryoshells have been installed – and, rather asymmetrically, both on LOx tanks. SpaceX recently rolled the first LN2 tank cryoshell to the farm and could install it soon but as of now, it will likely be weeks before the orbital tank farm will have sleeved, insulated LOx, LN2, and LCH4 tanks ready for testing.
At the moment, that’s one of the biggest points of uncertainty standing between SpaceX and the ability to test Super Heavy or Starship at the orbital launch site. It’s entirely unclear if uninsulated GSE tanks can support any kind of substantial testing – like, say, the first full Super Heavy static fire test campaign – before their contents effectively boil off. As such, it’s a bit of mystery why SpaceX then had at least three tanker loads of liquid nitrogen – likely more than 70 tons (~150,000 lb) total – delivered to the orbital tank farm on September 19th.
By all appearances the first time that the farm’s actual main tanks have been filled with anything, that liquid nitrogen seems to have been loaded into one or both of the two insulated LOx tanks. There are two or three main explanations. First, SpaceX could simply be testing those more or less completed tanks with their first cryogenic fluids. Those partial ‘cryo proof’ tests would also help clean and flush out the interior of the LOx tanks, removing mundane debris or contamination that could become a major hazard when submerged in a high-density oxidizer. Given that both tanks can easily hold ~1300 tons (~2.9M lb) of liquid nitrogen, 70 tons is more of a tickle than a test, though, so a magnitude more would need to be delivered to perform even a half-decent bare-minimum cryoproof.
The other distinct possibility is that SpaceX plans to temporarily use one or both of the only two finished orbital pad tanks to store liquid nitrogen for Super Heavy Booster 4’s first cryogenic proof test. Either way, SpaceX has test windows scheduled every day this week, beginning with a six-hour window that opens at 5pm CDT today (Sept 20). Stay tuned to find out what exactly SpaceX plans to test and if the orbital tank farm and its first taste of liquid nitrogen are involved!
United Airlines CEO Scott Kirby said that SpaceX’s Starlink satellite internet is its leading competitive advantage in the U.S. airline industry. However, in recent comments, while he described the service as “the biggest competitive advantage” the carrier currently holds, he also acknowledged that the edge is temporary.
“…everybody eventually is going to have high-speed low earth orbit internet connectivity. It’s going to be a must-have. We are going to have a few years of being the only airline that has it at scale, and that’s our mission,” Kirby said. Until everyone has it, United aims to capitalize on its head start by converting trial users into long-term loyal customers.
🚨 United CEO Scott Kirby calls Starlink “the biggest competitive advantage,” but says it’s temporary.
“I think it’s the biggest competitive advantage. And it’s temporary. Like it’s not, everybody eventually is going to have high speed low earth orbit internet connectivity. It’s going to be a must-have. But we are going to have a few years of being the only airline that has it at scale, and that’s our mission.”
“I think we’re going to convince customers that United is the best airline and we’re going to get customers to switch their loyalty, to get our credit card, switch their loyalty to United. Not because of Starlink. They’re going to try us for Starlink and they’re going to stay with all the other technology, and everything else is better, and the technology in particular is so much better than technology other, and it’s accelerating because we’ve got the right tech stack, and because we’re like, our gap is getting wider and wider with our technology every day.”

United has moved faster than its rivals on Starlink installations. As of mid-to-late October 2026, the system was on roughly 43 percent of its fleet, with plans to reach 61 percent by year-end, 87 percent by June 2027, and full fleet coverage by the end of next year.
The airline already operates more Starlink-equipped flights than the rest of the U.S. industry combined. Los Angeles International Airport is scheduled to become United’s first 100 percent Starlink hub in the first half of 2027, and the carrier’s app will display the likelihood that any given flight has the service.
Kirby has pointed to early evidence that the offering influences booking decisions. Some passengers loyal to other airlines are already switching flights for Starlink connectivity, something the airline, along with American Airlines, has tried to leverage against competing airlines. Both companies used status-match programs, and some of those customers are pursuing company-specific credit cards, which signals an intent to stay.
Once onboard, these customers encounter the airline’s broader investments in aircraft, larger seat-back screens, oversized bins, connection tools, and a mobile app that Kirby says outperforms competitors. Wi-Fi satisfaction scores on Starlink-equipped planes have been reported to be nearly double those on aircraft with other systems.
Competitors are moving slowly to do the same. Southwest Airlines began installations in 2025 and expects to complete them soon. Delta is pursuing Amazon’s Leo system, while American expects to start Starlink work in early 2027 and has not yet detailed regional-fleet plans. This timeline gap gives United a multi-year window in which it remains the only major U.S. carrier offering Starlink at scale.
Kirby has framed the strategy as pressing that advantage while simultaneously widening gaps in other technology areas so that customers who try United for the Wi-Fi remain for the overall experience.
The approach reflects a calculated bet that superior in-flight connectivity can accelerate share gains and support longer-term financial targets, including a 10 percent pre-tax margin goal.
High-speed internet is particularly valued by premium and business travelers who can work or stream reliably. As low-Earth-orbit service becomes ubiquitous, the temporary nature of the pure connectivity edge means United’s retention will depend on whether its other product and operational improvements keep pace.
Tesla Cybercab skips the traditional paint shop entirely, marking an unorthodox process for coloring the fully autonomous vehicle. However, the decision was a smart one, as it slashed factory costs, floor space utilization, and complexity, since Tesla relied on specialized alloys and in-mold coloring.
Munro Live was given the opportunity to do a factory walkthrough with Tesla Vice President of Vehicle Engineering Lars Moravy, who explained and detailed how Cybercab production at Giga Texas eliminates one of the automotive manufacturing industry’s most expensive and space-hungry elements.
A conventional paint line can cost hundreds of millions of dollars and require a million man-hours to build. Moravy framed the choice around Tesla’s core rule: “Question the requirements: why do you need paint?”
🚨 Super cool quote from the Cybercab breakdown on the decision to avoid traditional paint:
“One of the most expensive parts of the factory is a paint line… a few hundred million dollars, a million man hours to build one… rule number one at Tesla, question the requirements. Why do you need paint?… the alloys we use in the castings… don’t oxidize and reduce strength over time.” -@larsmoravy
Model Y and Cybertruck bodies are fully coated and painted. On Cybercab, only the side pieces get the anti-corrosion dip coat, and there’s no paint shop at all, which helps cut factory floor space per car by about 50%.

The structural answer lies in material selection. The aluminum alloys used in Cybercab’s front and rear castings do not oxidize and lose strength over time, the way many common automotive aluminum alloys do. Only the side modules, built around hot-stamped boron-steel door rings, receive an anti-corrosion e-coat, or dip coat. Front and rear modules skip coating altogether.
Model Y and Model 3 bodies, by contrast, are fully coated and painted.
Exterior colors come from the plastics shop, which Tesla engineers described as “our paint shop” for the Cybercab. Body panels are produced via reaction injection molding, referred to as RIM. Color is then mixed into a polyurethane resin at the mix head immediately before injection, so the panel emerges already colored with a Class-A surface.
Robots trim overflow to control sink marks and flow lines. The process avoids conventional spray-paint defects like orange peel and paint bleed. Scratches can still be repaired with compatible coatings that behave “basically like paint.” Because color is integral rather than a surface layer, shallow scratches do not expose a contrasting undercoat.
The secret behind Tesla’s Cybercab Gold goes well beyond just the color
Tesla has also explored related approaches, including in-mold lamination and painted films on stamped panels.
The manufacturing payoff is substantial because removing the paint shop, combined with the “unboxed” modular process that builds and tests front, rear, side, and center modules in parallel before a short final assembly, cuts factory floor space per vehicle by about 50 percent.
Final assembly itself uses only about 25 automated stations, far fewer than the typical Model Y line, and the overall line runs at about 78 percent automation, Moravy said. The approach also eliminates volatile organic compound emissions associated with traditional spray painting for these panels and shortens the coloring cycle from hours to minutes.
Cybercab’s paint strategy is clearly less about aesthetics than about systematically deleting capital-intensive, energy-heavy, and space-consuming steps once material science and process design make them unnecessary. It is a concrete example of Tesla applying first-principles questioning to one of the auto industry’s most entrenched factory requirements.
Investor's Corner
Tesla has a Cybercab problem nobody saw coming
Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.
Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”
Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.
The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.
Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.
The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.
Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”
