SpaceX Starship kicks off busy week of tests to prepare for flight debut
After many delays, SpaceX’s fifth full-scale Starship prototype is almost ready for a busy week of crucial tests that will determine whether the rocket will become the first of its kind to take flight.
On June 24th, SpaceX lifted Starship serial number 5 (SN5) onto a robotic transporter and rolled the giant steel rocket about a mile down the road to the company’s nearby test facilities and launch pad. Already slowed down a number of weeks by Starship SN4’s explosive end a month prior, teams were in the middle of completing extensive pad repairs (and likely some upgrades, too). Nevertheless, about a week after arriving at the pad, SpaceX kicked off two important tests – both of which SN5 would need to pass to move on to bigger challenges.
Pass those tests Starship SN5 certainly did, completing an ambient temperature pressure test to check for leaks, immediately followed by a cryogenic proof test that proved the ship was structurally sound and ready for short hops. While significant, SpaceX has only tested SN5 (and its repaired pad systems) with benign liquid nitrogen – still extremely cold but chemically unreactive (i.e. nonexplosive). The pad repairs still need to be fully put through their paces with combustible liquid methane and oxygen propellant, as does Starship SN5. Enter today’s planned test.
Barring additional (rather likely) delays, SpaceX is scheduled to put Starship SN5 through its first fueling test(s) during a window stretching from 8am to 5pm CDT on Monday, July 20th. Assuming that the “fueling test” referred to in public road closure alerts is a routine wet dress rehearsal (WDR), the test will involve SpaceX loading Starship SN5 with a large volume of liquid oxygen and methane propellant – similar to but substantially riskier than a liquid nitrogen proof test. SpaceX actually appeared to briefly attempt such a test on July 17th but signs that Starship SN5 was pressurized quickly disappeared and the road closure was lifted, signaling an abort.
Two and a half days of tweaks later, SpaceX’s July 19th closure was cancelled but the July 20th instance remains in place. If successful, Starship SN5 is expected to attempt to static fire its lone Raptor engine perhaps just a few days later, although that obviously assumes that both SN5 and the new pad hardware function perfectly during their biggest test yet.

Much like SN4’s several successful Raptor static fires, Starship SN5’s one or several tests aren’t expected to be any different. If the first test is a perfect success, proving that the rocket and Raptor engine SN27 are healthy and operating as a cohesive unit, SpaceX’s next goal is the flight debut of a full-scale Starship. Thanks to a broad FAA launch license effectively permitting unlimited suborbital Starship flight tests, SpaceX technically no longer has to stick to the 150m (~500 ft) ceiling originally set for Starhopper, but chances are good that it will still be the general target.
Stay tuned for an unofficial NASASpaceflight.com livestream of today’s planned Starship SN5 fuel test, should it remain on schedule.

Musk’s massive Terafab project will get final location soon
Elon Musk’s massive Terafab project, which will be the first true conglomeration between each of his major entities, is set to get its final location soon, the CEO said on Tesla’s recent earnings call.
“The Terafab, we expect to announce a location soon, and provide more details about our plans in that regard. We’ll leave that to the product, the launch announcement rather than try to squeeze it into an earnings call,” Musk said last Wednesday.
Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Terafab was announced by Musk back in March and was essentially a massive, vertically integrated semiconductor manufacturing project that would provide all the chips the three companies needed for their AI initiatives without needing third-party companies.
The plant will produce over 1 terawatt of AI compute each year, and will help back up projects like Optimus, Full Self-Driving, and other AI-based projects that Musk’s companies are working on.
In April, less than a month after the project was launched, Intel announced it would join the project, contributing manufacturing expertise and consulting to Terafab as a whole. Intel is one of three chip manufacturers that produce sub-5 nanometer chips at scale. TSMC and Samsung are the other two.
However, there was no true indication of where Terafab would end up, but most believe it will likely be somewhere in Texas. Business Insider has reported that SpaceX plans to build out Terafab in Grimes County, Texas, but this is unconfirmed.
Musk confirmed recently that it would not be on Giga Texas property, as it is simply too large.
The sheer scale of TERAFAB is going to be insane.
Elon said it wouldn’t be suitable for anywhere on Giga Texas property because it’s too big:
“We couldn’t possibly fit the Terafab on the GigaTexas campus. It will be far bigger than everything else combined there.

Terafab holds much of Musk’s grand ambitions for the future within its construct. It holds so much responsibility for the future and the biggest projects that Musk’s companies can imagine.
“I think this is a very big announcement and it deserves to have its own day in the spotlight and not be squeezed into an earnings call,” he said. “I do think Terafab is going to be an amazing initiative and a necessary one, and one without which we will be constrained in our ability to scale Optimus production, because we simply won’t have enough AI chips.”
He continued by stating that Terafab is necessary for scaling Optimus, which Musk said could be the biggest product of any kind of all time. “It’s crucial to solve that, and we’ll have to solve memory, logic, and packaging in order to scale Optimus.”

Elon Musk reveals SpaceX performed secret Starship test on Flight 13
SpaceX performed a secret test on a specific portion of Starship with its recent 13th test flight last week, CEO Elon Musk revealed.
Starship’s 13th test flight took place last Friday, and in many aspects, it was one of the most overwhelmingly successful launches in the project’s history.
All of the mission objectives were met without incident, both the Super Heavy Booster and Ship managed to perform safe splashdowns in the Gulf of America and the Indian Ocean, respectively, and the deployment of Starlink satellites came and went without any complications.

However, there was more on the agenda for SpaceX with Flight 13. Musk revealed an internal test of the ship’s heat shield tiles, as the space exploration company wanted to push them to the limits after previous issues.
Many noticed that Starship’s initial launch seemed to be more accelerated than normal, and that was not a mistake. Musk revealed that SpaceX decided to give Flight 13 an intentionally aggressive acceleration rate in an effort to test how well the tiles would remain attached to the ship:
This flight intentionally had much higher acceleration to test how well the heat shield tiles would remain attached at high dynamic pressure.
Test was successful.
— Elon Musk (@elonmusk) July 25, 2026
SpaceX had issues with some of the heat shield tiles remaining attached early on in the Starship program. The first six test flights presented some kind of anomaly with them, so the company’s big focus with them was to figure out a way to keep them intact through the duration of the flight.
Things truly improved as Flight 10 showed that ceramic tiles generally stayed attached to the ship far better due to refined attachment, as SpaceX utilized pins instead of adhesives. Flights 10 through 13 truly showed some clear progress with the heat shield tiles, and this latest test seems to be where some real progress was noticed, especially by Musk.
The 13th Starship launch last Friday was the second with Starship V3, SpaceX’s latest and greatest iteration of the spacecraft. Goals and ambitions are getting even grander as the project continues to progress. Musk has already hinted that SpaceX will likely try to catch Starship with Flight 14.

Tesla FSD takes owner on a 20,000+ mile joy ride
Tesla owner David Moss just pushed his intervention free FSD streak past 20,000 miles total.
Tesla Model 3 owner David Moss has spent the better part of eight months turning his vehicle into a rolling stress test for Full Self-Driving, and this week he pushed his single, continuous FSD streak past 20,000 miles without a human intervening.
Moss, a Tacoma, Washington resident who sells LiDAR scanning equipment for a living, first drew wide attention in December 2025 when he logged 10,000 consecutive miles on FSD v14.2. Days later he drove from the Tesla Diner in Los Angeles to Myrtle Beach, South Carolina, covering 2,732 miles in two days and 20 hours with zero disengagements, the first verified coast to coast autonomous drive in Tesla’s history. Tesla even featured the trip as an official customer story in March. That original streak eventually reached 12,961 miles across 30 states before ending in rural Wisconsin in January, when snow and single digit temperatures forced Moss to take over.
Tesla FSD successfully completes full coast-to-coast drive with zero interventions
He started over, and this run has gone further. In late May, Moss drove 3,760 miles across Canada with two companions, from Horseshoe Bay in Vancouver to a Tesla showroom in Halifax, again without a single intervention, a trip Tesla AI software VP Ashok Elluswamy publicly congratulated him for on X. In June, he pushed the same unbroken streak south, aiming to link the Canadian border to the Mexican border, and crossed 10,000 miles on Tesla’s newly added in car streak counter along the way, the first driver to do so since Tesla began showing confetti animations for the feature.

Special thank you to @DevinOlsenn, @scotsrule08, & @OwenSparks for helping co drive during all these fun adventures these last couple of months
Also thank you to @wholemars for always tracking me along the journey verifying it all with his… pic.twitter.com/CZ2yO6Ev0X

It’s worth noting that every mile is logged through the FSD Database, a community run tracker built by Tesla influencer Omar Qazi, well known as @WholeMars on X, that pulls telemetry straight from the car and records disengagements down to a tenth of a mile. That verification is what separates Moss’s numbers from casual claims on social media.
The streak itself is a fairly recent addition to Tesla’s software. FSD v14.2 introduced a Self Driving Stats panel tracking the ratio of autonomous to manual miles, and v14.3.4 added the live streak counter in June, which resets the moment a driver brakes, wrenches the wheel or cancels navigation. Reaching 20,000 miles on that counter means a single Tesla drove itself through countless highways, city grids, construction zones and Supercharger stalls without a single reset.
Moss has said the goal was never to set a record for its own sake, but to show, mile by verified mile, what the software can already do.
