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 begins expanding Robotaxi access: here’s how you can ride
You can ride in a Tesla Robotaxi by heading to its website and filling out the interest form. The company is hand-picking some of those who have done this to gain access to the fleet.
Tesla has begun expanding Robotaxi access beyond the initial small group it offered rides to in late June, as it launched the driverless platform in Austin, Texas.
The small group of people enjoying the Robotaxi ride-hailing service is now growing, as several Austin-area residents are receiving invitations to test out the platform for themselves.
The first rides took place on June 22, and despite a very small number of very manageable and expected hiccups, Tesla Robotaxi was widely successful with its launch.

However, Tesla is expanding the availability of the ride-hailing service to those living in Austin and its surrounding areas, hoping to gather more data and provide access to those who will utilize it on a daily basis.
Many of the people Tesla initially invited, including us, are not local to the Austin area.
There are a handful of people who are, but Tesla was evidently looking for more stable data collection, as many of those early invitees headed back to where they live.
The first handful of invitations in the second round of the Robotaxi platform’s Early Access Program are heading out to Austin locals:

Tesla likely saw an influx of data during the first week, as many traveled far and wide to say they were among the first to test the Robotaxi platform.
Now that the first week and a half of testing is over, Tesla is expanding invites to others. Many of those who have been chosen to gain access to the Robotaxi app and the ride-hailing service state that they simply filled out the interest form on the Robotaxi page of Tesla’s website.
That’s the easiest way you will also gain access, so be sure to fill out that form if you have any interest in riding in Robotaxi.
Tesla will continue to utilize data accumulated from these rides to enable more progress, and eventually, it will lead to even more people being able to hail rides from the driverless platform.
With more success, Tesla will start to phase out some of the Safety Monitors and Supervisors it is using to ensure things run smoothly. CEO Elon Musk said Tesla could start increasing the number of Robotaxis to monitors within the next couple of months.
A Tesla analyst today said that investors should not lose sight of what is truly important in the grand scheme of being a shareholder, and that any near-term drama between CEO Elon Musk and U.S. President Donald Trump should not outshine the progress made by the company.
Gene Munster of Deepwater Management said that Tesla’s progress in autonomy is a much larger influence and a significantly bigger part of the company’s story than any disagreement between political policies.
Munster appeared on CNBC‘s “Closing Bell” yesterday to reiterate this point:
“One thing that is critical for Tesla investors to remember is that what’s going on with the business, with autonomy, the progress that they’re making, albeit early, is much bigger than any feud that is going to happen week-to-week between the President and Elon. So, I understand the reaction, but ultimately, I think that cooler heads will prevail. If they don’t, autonomy is still coming, one way or the other.”

This is a point that other analysts like Dan Ives of Wedbush and Cathie Wood of ARK Invest also made yesterday.
On two occasions over the past month, Musk and President Trump have gotten involved in a very public disagreement over the “Big Beautiful Bill,” which officially passed through the Senate yesterday and is making its way to the House of Representatives.
Musk is upset with the spending in the bill, while President Trump continues to reiterate that the Tesla CEO is only frustrated with the removal of an “EV mandate,” which does not exist federally, nor is it something Musk has expressed any frustration with.
In fact, Musk has pushed back against keeping federal subsidies for EVs, as long as gas and oil subsidies are also removed.
Nevertheless, Ives and Wood both said yesterday that they believe the political hardship between Musk and President Trump will pass because both realize the world is a better place with them on the same team.
Munster’s perspective is that, even though Musk’s feud with President Trump could apply near-term pressure to the stock, the company’s progress in autonomy is an indication that, in the long term, Tesla is set up to succeed.
Tesla launched its Robotaxi platform in Austin on June 22 and is expanding access to more members of the public. Austin residents are now reporting that they have been invited to join the program.

Tesla surges following better-than-expected delivery report
Tesla saw some positive momentum during trading hours as it reported its deliveries for Q2.
Tesla (NASDAQ: TSLA) surged over four percent on Wednesday morning after the company reported better-than-expected deliveries. It was nearly right on consensus estimations, as Wall Street predicted the company would deliver 385,000 cars in Q2.
Tesla reported that it delivered 384,122 vehicles in Q2. Many, including those inside the Tesla community, were anticipating deliveries in the 340,000 to 360,000 range, while Wall Street seemed to get it just right.

Despite Tesla meeting consensus estimations, there were real concerns about what the company would report for Q2.
There were reportedly brief pauses in production at Gigafactory Texas during the quarter and the ramp of the new Model Y configuration across the globe were expected to provide headwinds for the EV maker during the quarter.
At noon on the East Coast, Tesla shares were up about 4.5 percent.
It is expected that Tesla will likely equal the number of deliveries it completed in both of the past two years.
It has hovered at the 1.8 million mark since 2023, and it seems it is right on pace to match that once again. Early last year, Tesla said that annual growth would be “notably lower” than expected due to its development of a new vehicle platform, which will enable more affordable models to be offered to the public.
These cars are expected to be unveiled at some point this year, as Tesla said they were “on track” to be produced in the first half of the year. Tesla has yet to unveil these vehicle designs to the public.
Dan Ives of Wedbush said in a note to investors this morning that the company’s rebound in China in June reflects good things to come, especially given the Model Y and its ramp across the world.
He also said that Musk’s commitment to the company and return from politics played a major role in the company’s performance in Q2:
“If Musk continues to lead and remain in the driver’s seat, 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.”
Ives maintained his $500 price target and the ‘Outperform’ rating he held on the stock:
“Tesla’s future is in many ways the brightest it’s ever been in our view given autonomous, FSD, robotics, and many other technology innovations now on the horizon with 90% of the valuation being driven by autonomous and robotics over the coming years but Musk needs to focus on driving Tesla and not putting his political views first. We maintain our OUTPERFORM and $500 PT.”
Moving forward, investors will look to see some gradual growth over the next few quarters. At worst, Tesla should look to match 2023 and 2024 full-year delivery figures, which could be beaten if the automaker can offer those affordable models by the end of the year.
