SpaceX is ready to build the first Starship destined for space after latest tests
After a busy several days of rocket hardware testing, Elon Musk says that SpaceX may be ready to build the first Starship prototype destined for space.
According to Musk, one test in particular – performed in South Texas just yesterday – is an encouraging sign that SpaceX’s Starship team is becoming increasingly competent at building the massive steel parts that will ultimately make up the generation launch vehicle. For SpaceX, the particular skills and expertise needed to precisely and consistently build a launch vehicle – let alone a rocket as large and complex as Starship – are quite a bit different from those it has mastered with Falcon 9, Falcon Heavy, and Dragon.
A lot of the expertise – particularly engineering talent, countless lessons-learned, and insight into reusability – is directly transferable from Falcon rockets to SpaceX’s Starship/Super Heavy program. Where it really isn’t transferable, however, is in the methods required to actually build the steel subcomponents that must ultimately be assembled together to form the rocket’s upper stage and booster. As a result, SpaceX has spent more than a year focused on building, testing, scrapping, improving, and re-testing any number of critical Starship components. Over the last four weeks (and last few days in particular), that testing has come to a head and Elon Musk believes the results have opened the door for SpaceX to begin building its first space-bound Starship prototypes.
SpaceX’s latest round of full-scale Starship hardware tests began just 10-20 days ago, depending on how one counts. Back around the start of the new calendar year, SpaceX began rapidly integrating two new Starship bulkheads and two cylindrical steel rings (barrel sections), ultimately delivering a finished ‘test tank’ after just 20 days of work. On January 10th, scarcely 24 hours after the two halves of the test tank were welded together, SpaceX sent the Starship test tank to its nearby launch pad and pressurized it with water until it quite literally burst.
Musk tweeted the results of that intentional test-to-destruction just a few hours after it was completed, revealing that SpaceX’s upgraded production and integration techniques enabled the tank to survive pressures almost 20% greater than the minimum Starships will need to perform orbital launches.
“Critically, the tank reached a maximum sustained pressure of 7.1 bar (103 psi), 18% more than the operating pressure (6 bar/87 psi) Musk says Starship prototypes will need to begin orbital test flights. At 7.1 bar, the test tank would have been experiencing an incredible ~20,000 metric tons (45 million lbf) of force spread out over its interior surfaces — equivalent to ~20% of the weight of an entire US Navy aircraft carrier. Perhaps even more impressive, that same Starship test tank was built from almost nothing extremely quickly, going from first weld to said pressurization test in just three weeks (20 days).
With relatively minor improvements to welding conditions and the manufacturing precision of Starship rings and domes, Musk believes that SpaceX can reliably build Starships and Super Heavy boosters to survive pressures greater than 8.5 bar (125 psi), guaranteeing a safety margin of at least 40%. Even a minor improvement of ~6% would give Starship a safety margin of 125%, enough – in the eyes of most engineering standards committees – to reasonably certify Starships for orbital test flights.”

Test Tank 2: The Tankening
This brings us to January 27th, a little over two weeks after SpaceX completed and burst the first standalone Starship test tank. Over the last week, SpaceX has quickly assembled a second Starship test tank, using a few clearly new methods and parts, as well as a brand-new tent built by the same company that Tesla used for Fremont’s fourth General Assembly line.
In the last few days, two new bulkheads and steel rings came together to form Starship test tank #2, which was subsequently prepped for transport and moved about a mile down the road to SpaceX’s launch facilities on the morning of January 27th. Scarcely a few hours later, well before anyone was paying close attention for test activities, Elon Musk took to Twitter to reveal that the second tank had already been subjected to a pressure test with water. That second tank reportedly survived up to 7.5 bar, an improvement of about 6% compared to the first tank.
This time, however, the tank wasn’t actually catastrophically destroyed by the pressure test, instead developing a leak around the weld connecting the two halves that lead SpaceX to back off. Musk says that that presumably small leak will now be repaired, after which the same tank will be tested again but with one significant difference. Musk says that Test Tank #2’s second pressure test will be performed with a cryogenic liquid — most likely liquid nitrogen (LN2).
In replies after his reveal, Musk noted that he believed the second test tank could perform significantly better if pressurized with a cryogenic liquid. That’s because certain types of steel – particularly those SpaceX has chosen for Starship – exhibit something known as cryogenic hardening when exposed to extremely cold temperatures, producing steel that can be dramatically stronger by some measures.
Ultimately, as mentioned above, a tank pressure safety margin of 125% is the minimum most engineering standards provide for any given orbital-class launch vehicle. At 7.5 bar, even under the very unlikely assumption that Starship tanks will not see even a marginal strength increase at cryogenic temperatures, SpaceX’s second Starship test tank has officially hit that 125% safety margin. As Musk himself noted on Monday, he is now confident that SpaceX can immediately start building the first Starship destined for spaceflight and further revealed that two of that particular Starship’s three tank domes are already nearing completion.
Known as Starship SN01 (serial number 01), there’s a strong possibility that the massive spacecraft will never reach higher than a 20 km (12.5 mi) flight test SpaceX intends to perform. The company’s rapidly changing strategy may very well mean that SN01 – now ‘go’ for production – could also support suborbital spaceflight testing and maybe even the first orbital Starship launch, although orbital launches will require a Super Heavy booster. Elon Musk, for one, has already christened Starship SN01 an “orbital vehicle”.

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.
