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 finally got its Nevada Robotaxi Permit but with a few catches hard to miss

Nevada granted Tesla’s robotaxi permit, but capped the fleet at just ten vehicles for now.

Tesla has received its robotaxi permit in Nevada, more than two months after regulators closed the public comment period on the company’s application. News of the approval surfaced Wednesday night when Tesla investor and longtime company watcher Sawyer Merritt posted a copy of the interim order, and the Nevada Transportation Authority’s own carrier registry now lists the permit, AVNC Permit 002 under Docket 26-05015, as active for Tesla Robotaxi, LLC.

Tesla asked Nevada in June for authority to run up to 5,000 vehicles in Clark County within a year, however the permit the NTA issued is initially capping Tesla at ten fully autonomous vehicles and confines them to a defined geofence along the Las Vegas Strip corridor. Any expansion of that operating area, or any increase to the fleet size, requires the NTA’s approval first.

The order also sets rules that look more restrictive than what Tesla runs in Austin. Rides are barred on roads with posted speed limits above 45 miles per hour, pickups are off limits within a quarter mile of Harry Reid International Airport without separate authorization, and every vehicle has to carry visible “Robotaxi” markings while notifying riders before each trip that no one is driving. The order also requires “appropriate human supervision”, language that suggests Nevada isn’t ready to let Tesla offer the rides without a safety monitor that it has run in parts of Austin since January. As with standard protocol with robotaxi services, Tesla must report any accident, system failure, or vehicle that becomes stranded on a Nevada road within five business days.

Tesla is entering a market Nevada already knows well. Zoox, the Amazon owned robotaxi company, has run its own autonomous vehicle permit in the state since last year, building up to roughly 100 vehicles and 350,000 rides along the Strip. That history likely explains why the NTA started Tesla at ten cars rather than the fleet size the company asked for. The agency has a template for scaling a permit up once a company proves out its safety record.

Tesla’s Nevada application first surfaced in June, when the company filed for the permit alongside plans for a maintenance hub in southwest Las Vegas. The company has said it won’t meaningfully scale its robotaxi fleet anywhere until FSD v15 ships, expected in late 2026 or early 2027, which makes the ten vehicle cap less of a constraint today than it might look on paper. For now, Tesla has the legal right to start Nevada rides. Whether it starts before FSD v15 arrives is a separate question the permit doesn’t answer.

Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.

Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.

The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla announces 100k Powerwalls are participating in Virtual Power Plants

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.

Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.

The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.

Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk teases Tesla Roadster unveiling once again

Published

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.

A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”

Musk agreed:

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.

It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:

“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”

The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.

However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.

For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”

We sure hope.
