SpaceX Starship rocket set to reach full height for the second time ever
A SpaceX Starship prototype is on track to become the first to reach its full, operational height in a permanent fashion, following in the footsteps of a much earlier prototype that had its nose section temporarily installed last year.
Known as Starship Mk1, that prototype served as more of a learning experience, pathfinder, and mockup over the ~8 months it took to build it and the few weeks it took to destroy it. While its conical nose section was partially outfitted with smaller ‘header’ propellant tanks, it was never fully installed, with SpaceX only temporarily stacking it on top of Starship Mk1’s tank section to serve as the centerpiece of CEO Elon Musk’s October 2019 update event. Mk1’s nosecone was removed shortly after the event was over, while the rocket’s more important tank section was rolled to a nearby launch pad for testing.
More than six months later, Starship SN5 appears to be firmly on its way to becoming the first of SpaceX’s next-generation launch vehicle prototypes to have a (mostly) functional nose section permanently installed. If that ends up being the case, SpaceX’s fifth full-scale Starship prototype may become the first to have multiple Raptor engines installed and the first to perform a high-altitude flight test. Of course, that will depend quite heavily on the fate of Starship SN4, currently trapped in limbo after a May 19th static fire caused SpaceX to partially lose control of the rocket.
While not immediately clear, comments made by CEO Elon Musk and SpaceX officials suggested that the company was aiming to perform low-altitude hops with Starship SN4 and graduate to high-altitude testing with the next prototype off the assembly line (SN5). With a development program as agile as SpaceX’s Starship effort, however, plans are liable to change at almost any moment.
On May 17th, however, it became clear that – at least for the time being – SpaceX fully intends for Starship SN5 to become the first serially-produced ship to have a nosecone installed. On that Sunday, a brand new steel nose section – the fourth built by SpaceX in the last few months – was rolled out of a massive factory tent, revealing labels that rather unambiguously read “SN5”.
SN5 refers to Starship serial number 5, the fifth full-scale rocket prototype overall and fourth built since the start of 2020. Over the last six or so months, SpaceX has dramatically expanded its production footprint in South Texas, reaching a point now where it’s churning out a rough Starship prototype every month, on average. Starship SN5 is no different, with its tank section largely completed as of May 15th, give or take a day or two.
Now, on May 19th, a new collection of five stacked steel rings appeared alongside Starship SN5’s largely completed tank and engine section. Combined with the new nosecone labeled “SN5”, it’s now readily and unequivocally apparent that the prototype is probably a matter of days away from having a nosecone installed. Unless SpaceX has adopted different methods for Starship SN6 production and assembly, a stack of five steel rings – lacking any sign of a tank dome welded inside it – will serve as the base that SN5’s nosecone can be stacked on top of. Once stacked with its nose section, Starship SN5 will measure some 50m (~165 ft) tall – at least several meters taller than a Falcon 9 booster.
The nosecone itself is also quite interesting, featuring two sets of four mysterious thruster nozzles, signs of interior components and reinforcements, and two recessed struts presumably meant to attach to Starship’s forward flaps.
While exciting, there is certainly still a chance that Starship SN4 – trapped at the launch pad – will have to be destroyed or will be unsalvageable even if SpaceX is able to finally access and safe the prototype. If so, Starship SN5 will likely take its place, performing a Raptor static fire, a ~150m (~500 ft) hop test, and an additional ~3 km (~1.9 mi) flight test before potentially moving on to triple Raptor operations and high-altitude flights. Stay tuned for updates on SN4’s fate and SN5’s production status.
Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.
Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.
CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.
The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.
In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.
The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.
Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”
Robotaxi operating hours moved from 10pm to 11pm.

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.
Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.
The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.
Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.
The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
