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.

SpaceX bought run-of-the-mill off-the-shelf storage tanks to build its suborbital Starship launch complex. That won’t be the case for its orbital-class big brother. (NASASpaceflight – bocachicagal)

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’s new Robotaxi geofence shape is an FU by Elon Musk to the competition

Maybe it’s all pareidolia. But maybe it’s not. After all, Tesla embraced the first geofence expansion for what it appeared to be.

tesla austin robotaxi geofence and elon musk laugh from meme review

Tesla expanded its Robotaxi geofence in Austin once again early Sunday morning. The new shape seems to be somewhat of a proverbial, and potentially literal, middle finger to the competition.

If you thought the first expansion was a message to the competition and doubters of the company’s ride-hailing service, you probably will believe the second expansion is an even stronger gesture.

Tesla’s first expansion did not go unnoticed, as its shape was particularly recognizable. The company has always operated with a sense of humor, and it embraced what it did. Some, including me, took it as a message to competitors: We can expand in any direction, in any size, at any time. We’ll prove it.”

They picked a shape and went with it:

Tesla’s Robotaxi expansion wasn’t a joke, it was a warning to competitors

It is evident that Tesla is keeping its humor up to continue to show a few things. The first is that it really can expand in any direction it wants and that’s how it is choosing to show it.

The second, well, maybe it’s an edgier way to show doubters that it is really executing on Robotaxi:

Maybe it’s all pareidolia. But maybe it’s not. After all, Tesla embraced the first geofence expansion for what it appeared to be. This might be a similar occurrence, and it might be sending another message to the competition, critics, and doubters.

The expansion was a near-doubling of the geofence Tesla offered previously. After the initial geofence covered just about 20 square miles, Tesla was able to more than double it to 42 square miles with the first growth. This new geofence shape was just under double, and is about 80 square miles.

Tesla’s rapid expansion has impressed many, especially considering the service area has roughly doubled for the second time in well under two months. The Robotaxi service was first offered on June 22.

Tesla executes ‘a must’ with Musk as race to AI supremacy goes on: Wedbush

Dan Ives of Wedbush says Tesla made the right move getting Elon Musk his pay package.

Tesla (NASDAQ: TSLA) executed what Wedbush’s Dan Ives called “a must” this morning as it finalized a new pay package for its CEO Elon Musk.

The move helped give Musk his first meaningful compensation at Tesla since 2017, when the company offered a pay package that was based on performance and proven growth. That package was approved by shareholders on two separate occasions, but was denied to Musk both times by the Delaware Chancery Court.

On Monday, Tesla announced on X that it had created a new package that would give 96 million shares of restricted stock to Musk to compensate him for the “immense value generated for Tesla and all our shareholders.”

The details of the pay package are designed to retain Musk, who has voiced some concerns about his control of Tesla, as “activist shareholders” have used lawsuits to disrupt the previously approved package.

Tesla rewards CEO Elon Musk with massive, restricted stock package

Ives says Musk’s retention is ‘a must’

Ives said in a note to investors on Monday that with the raging AI talent war that Tesla made a smart move by doing what it could to retain Musk.

He wrote:

“With the AI talent war now fully underway across Big Tech, we believe this was a strategic move to keep TSLA’s top asset, Musk, would stay focused at the company with his priority being to bolster the company’s growth strategy over the coming years. With this interim award increasing Musk’s voting rights upon this grant, which Musk honed in on and mentioned was increasingly important to incentivize him to stay focused on the matters at hand, this was a strategic move by the Board to solidify Musk as CEO of Tesla over the coming years with this framework for Musk’s pay package and greater voting control removing a major overhang on the story.”

He went on to say:

“While the groundwork is now in place for the next few years, it will be critical for the Tesla Board of Directors to get this long-term compensation strategy in place prior to the company’s November 6th shareholder meeting which would address the elephant in the room and remove a significant overhang on the stock.”

Wedbush maintained its Outperform rating and its $500 price target on the stock.

Tesla CEO Elon Musk reveals ideal timeline for insane self-driving feature

Tesla CEO Elon Musk has extremely optimistic expectations for Full Self-Driving progress by the end of 2025.

Tesla CEO Elon Musk has revealed his ideal timeline for what would likely be the most insane self-driving feature: the ability for drivers to play video games at the wheel.

There are a handful of videos out there of drivers already performing this task. Nobody using Tesla’s Full Self-Driving suite should perform these activities, as the company maintains the system is not fully autonomous.

Drivers are responsible for the vehicle and should be prepared to take over.

Tesla has put a lot of faith in its development of Full Self-Driving and has made tremendous strides over the past few years. Capabilities have gotten more refined and accurate through various methods, including data collection and hardware improvements.

Tesla kicks Robotaxi geofence expansion into high gear in Austin

It has gotten so good that Tesla launched a Robotaxi platform in Austin, Texas, on June 22. Passengers can hop in the back of a Model Y and will be transported around the city in a confined geofence that is about 90 square miles in size. There is nobody in the driver’s seat, but there is a Safety Monitor in the passenger’s seat.

Tesla launched a similar experience in California’s Bay Area last week, but the company has placed the Safety Monitor in the driver’s seat for that region for the time being.

Eventually, Tesla will get to a point where no monitor is needed, and the vehicles will be able to drive themselves. Many believe that it is a few years away, but Musk believes Tesla could achieve it very soon.

After a video of someone playing Grand Theft Auto in their Cybertruck while operating Full Self-Driving was shared on the social media platform X, Musk said this capability would be available in “probably 3 to 6 months, depending on regulatory approval in your city and state.”

It is important to remember that Musk has been very optimistic regarding autonomy timelines with Tesla projects. We heard for many years that the company would have self-driving vehicles “by the end of the year,” and those projects did not come to fruition.

While there was progress, there were no fully autonomous vehicles or software versions for customers.

With that being said, Tesla has made tremendous strides in its quest for autonomous vehicles this year, and launching a Robotaxi platform was a huge step in the right direction.
