SpaceX’s odd Starbase propellant storage tank prototype passes first test
Likely to the relief of many, SpaceX appears to have successfully tested a prototype of the custom-built Starbase propellant storage tanks that will eventually hold thousands of tons of fuel and oxidizer.
For reasons unknown, SpaceX’s built its first ground support equipment (GSE) ‘test tank’ – a subscale prototype designed to quickly verify basic production quality and design goals – months after it began mass-producing operational storage tanks. In fact, of the seven total GSE tanks expected to be built, SpaceX has already completed seven, installed five, and scrapped one. Known as GSE4, SpaceX actually used modified parts of that scrapped tank to assemble the GSE test tank that first rolled to Starbase’s launch (and test) facilities on August 23rd.
Two days later, SpaceX subjected the small tank to its first test.
Given that SpaceX appears to have almost retroactively assembled the GSE4 test tank after building the final products, the results from its testing were always going to be significantly more anxiety-inducing than any of the more than half-dozen other tanks the company has tested in the last year and a half. Having already fabricated, assembled, or even installed six of seven planned GSE tanks, the discovery of major issues during testing could potentially cause months of delays by forcing SpaceX to perform lengthy repairs or even fully scrap all six existing tanks and start over.
Thankfully, at least for the time being, it appears that SpaceX can write off those potential worst-case scenarios. On August 25th, SpaceX took advantage of a test window initially believed to be for Starship S20 and put the cobbled-together GSE4 tank through its paces for the first time. As with previous test tanks, all SpaceX can really do is fill the prototype with liquid nitrogen (LN2), a non-flammable alternative to liquid oxygen or methane propellant that is approximately as cold and heavy. As a storage tank prototype, though, GSE4 has no need for hydraulic ram setups used to simulate the thrust of Raptor engines on several previous prototypes.
As such, one or several cryogenic proof tests were all that were ever really in GSE4’s future. On GSE4’s first test, SpaceX performed a more or less normal cryogenic proof, completely filling the tank with LN2, closing its vents, and then allowing the natural process of LN2 boiloff to raise the tank to the desired test pressure. However, unlike other test tanks, GSE4 never actually appeared to reopen its main vents. In fact, SpaceX may have never actually drained liquid nitrogen from the test tank, instead simply letting it slowly warm up and boil off into gas that was seemingly managed and vented by ground systems instead of the tank itself.
As a result, GSE4 stayed frosty (indicating a significant amount of remaining liquid nitrogen) for more than eight hours, strongly implying that it was either very slowly drained or simply allowed to warm up naturally. Given that large cryogenic storage tanks really don’t have to be significantly pressurized to complete their job, it’s possible that GSE4’s first test was primarily meant to verify the basic structural integrity of a tank that’s slightly different than those on Starship and, more importantly, test a different method of pressure and fluid management where most of that work is done by external, permanent systems on the ground.
That’s exactly what one might expect of rocket tankage slightly modified to serve as ground storage tanks. SpaceX’s GSE tanks never have to act as self-contained units and can instead rely almost entirely on separate systems.
Aside from verifying that that slightly different method of tank operations works as expected, GSE4’s first test likely also allowed SpaceX to better characterize the thermal properties of the thin steel skin and domes that are Starship and GSE tanks. Unlike GSE4, operational GSE tanks will be enclosed inside 12m (~40 ft) wide ‘cryo shells’ designed to insulate their cryogenic contents, but the insulative properties of the inner tanks (or the lack there of, rather) will still determine how well that insulation works and how much is actually needed to reach the desired boiloff rates. A contractor hired by SpaceX has already completed all seven cryo shells, so any results gathered from GSE4 will obviously be more of a check than a developmental test, but data is still data.

Tesla Superchargers open to Lucid Air, but not without one key thing
Lucid’s full lineup of EVs is now able to use Tesla Superchargers in the United States and Canada.
Tesla Superchargers will be open to Lucid Air vehicles starting on July 31, a move that comes nearly two years after the companies agreed to terms that would allow them to partner.
Lucid joins a long list of EV makers that have a full lineup of EVs that can utilize Tesla’s extensive Supercharger Network across the United States and parts of Canada. In all, over 32,500 Tesla Superchargers will be accessible to Lucid owners at the end of the month.
Lucid NACS adoption ‘must have been a bitter pill to swallow’: Elon Musk
All Air models, regardless of year or trim level, will gain access to the entire North American Tesla Supercharger Network. It will just need one key thing to charge: an NACS adapter.
Lucid Air sedans will require a DC NACS to CCS1 adapter in order to enable charging at the Tesla stalls. These will be priced at $220 plus tax.
Emad Dlala, Senior VP of Powertrain at Lucid, said:
“In addition to offering the longest-range electric vehicle available, Lucid is committed to offering our customers seamless and wide access to public charging. Access to the Tesla Supercharging Network for the Lucid Air is yet another major milestone.”
Charging speeds will allow Air EVs to charge at up to 50 kW, gaining up to 200 miles of range per hour.
As for the Lucid Gravity, the company’s SUV, it will not require the adapter because of its native NACS port. It gained access to the Supercharger Network in January.
Although Lucid Airs will not be able to charge at the rate of some other vehicles, they do boast some of the best range ratings in the EV industry. Having the luxury of additional charging piles to access will increase the value of the long-range ratings Lucid offers with its vehicles.
Lucid joins several other automakers that have a full lineup of EVs that have access to the Tesla Supercharger Network:
- Ford
- Rivian
- General Motors (Chevrolet, GMC, Cadillac)
- Volvo
- Polestar
- Nissan
- Mercedes-Benz
- Hyundai
- Kia
- Genesis
- Honda
- Acura
- Aptera
Other brands, like BMW, Audi, Volkswagen, Porsche, and Subaru, are expected to gain access in the near future.

Tesla Robotaxi wins over firm that said it was ‘likely to disappoint’
Tesla Robotaxi recently won over a Wall Street firm that had recently said the platform was “likely to disappoint.”
Tesla Robotaxi recently won over a Wall Street firm that had recently said the platform was “likely to disappoint.” The ride-hailing service has been operating for about a month, and driverless rides have been offered to a small group of people that continues to expand nearly every day.
JPMorgan went to Austin to test the Tesla Robotaxi platform, and it did so just a few weeks after listing Tesla as one of its “six stocks to short” in 2025. Highlighting the loss of the EV tax credit and labeling the Robotaxi initiative as one that was “likely to disappoint,” despite Tesla’s prowess in its self-driving software.
Analyst Ryan Brinkman has been skeptical of Tesla for some time, even stating that the company’s “sky-high valuation” was not in line with other stocks in the Magnificent Seven.
However, a recent visit to Texas that was made by JPMorgan analysts proved that the Robotaxi platform, despite being in its earliest stages, was enough for them to change their tune, at least slightly. The firm gave its props to the Tesla Robotaxi platform in a note by stating it was “certainly solid and felt like a safe ride at all times.”
It’s always nice to hear skeptics report positive experiences, especially as Robotaxi continues to improve and expand.
Tesla has already expanded its geofence for the Robotaxi suite in Austin, picking a very interesting shape for its newest boundaries:
Tesla’s Robotaxi expansion wasn’t a joke, it was a warning to competitors
As Robotaxi expands, Tesla is dealing with competition from Waymo, another self-driving ride-hailing service that is operating in Austin, among other areas. After Tesla’s expansion, which brought its accessible area to a greater size than Waymo’s, it responded by doubling its geofence.
Waymo’s expansion surpassed Tesla’s size considerably, and it seems Tesla is preparing to expand its geofence in the coming weeks.

The Robotaxi platform is not yet available to the public, but Tesla has been inviting more people to try it with every passing day. Currently, the map is roughly 42 square miles, but many believe Tesla is able to broaden this by a considerable margin whenever it decides.
Investor's Corner
Tesla needs to confront these concerns as its ‘wartime CEO’ returns: Wedbush
Tesla will report earnings for Q2 tomorrow. Here’s what Wedbush expects.
Tesla (NASDAQ: TSLA) is set to report its earnings for the second quarter of 2025 tomorrow, and although Wall Street firm Wedbush is bullish as the company appears to have its “wartime CEO” back, it is looking for answers to a few concerns investors could have moving forward.
The firm’s lead analyst on Tesla, Dan Ives, has kept a bullish sentiment regarding the stock, even as Musk’s focus seemed to be more on politics and less on the company.
However, Musk has recently returned to his past attitude, which is being completely devoted and dedicated to his companies. He even said he would be sleeping in his office and working seven days a week:

Nevertheless, Ives has continued to push suggestions forward about what Tesla should do, what its potential valuation could be in the coming years with autonomy, and how it will deal with the loss of the EV tax credit.
Tesla preps to expand Robotaxi geofence once again, answering Waymo
These questions are at the forefront of what Ives suggests Tesla should confront on tomorrow’s call, he wrote in a note to investors that was released on Tuesday morning:
“Clearly, losing the EV tax credits with the recent Beltway Bill will be a headwind to Tesla and competitors in the EV landscape looking ahead, and this cash cow will become less of the story (and FCF) in 2026. We would expect some directional guidance on this topic during the conference call. Importantly, we anticipate deliveries globally to rebound in 2H led by some improvement on the key China front with the Model Y refresh a catalyst.”
Ives and Wedbush believe the autonomy could be worth $1 trillion for Tesla, especially as it continues to expand throughout Austin and eventually to other territories.
In the near term, Ives expects Tesla to continue its path of returning to growth:
“While the company has seen significant weakness in China in previous quarters given the rising competitive landscape across EVs, Tesla saw a rebound in June with sales increasing for the first time in eight months reflecting higher demand for its updated Model Y as deliveries in the region are starting to slowly turn a corner with China representing the heart and lungs of the TSLA growth story. Despite seeing more low-cost models enter the market from Chinese OEMs like BYD, Nio, Xpeng, and others, the company’s recent updates to the Model Y spurred increased demand while the accelerated production ramp-up in Shanghai for this refresh cycle reflected TSLA’s ability to meet rising demand in the marquee region. If Musk continues to lead and remain in the driver’s seat at this pace, we believe Tesla is on a path to an accelerated growth path over the coming years with deliveries expected to ramp in the back-half of 2025 following the Model Y refresh cycle.”
Tesla will report earnings tomorrow at market close. Wedbush maintained its ‘Outperform’ rating and held its $500 price target.
