SpaceX separates Starship prototype’s nose and tail to install giant propellant tanks
After a handful of days as an impressive monolith stood along the coastal wetlands of Texas, SpaceX technicians have once again separated the nose and tail sections of the first Starship prototype to allow additional integration and assembly work to continue. The craft’s three Raptors were also removed and stored nearby, shown to be barebones facsimiles standing in for flightworthy hardware that could arrive in the next month or two.
Up next, three or four propellant tank domes – currently being assembled and welded together on-site – will likely be installed inside the steel hull of the giant Starship prototype’s aft barrel section. Known as bulkheads, the installation of those tank domes will bring SpaceX one step closer to performing hop tests of the simultaneously bizarre, confusing, and beautiful craft.

At this point in time, it appears that Starhopper is some odd combination of showmanship and actual hardware meant to test certain aspects of the first orbital Starship build, said to be complete as early as June 2019 by CEO Elon Musk. In the last week or so, SpaceX technicians attached and welded over Starhopper’s two sections – an aft barrel with legs and Raptors and a conical nose – and even did a sort of photoshoot, removing an on-site fence for a photo that Musk later shared while stating that the vehicle had “completed assembly”.

One could argue that assembly is not exactly complete if the given product has to be pulled in half to install significant new components. Regardless, the external skin, aft barrel section, and rough landing legs do appear to be more or less complete from a very basic structural perspective, although there is clearly much work still to be done if the vehicle’s tank bulkheads haven’t been installed. Aside from completing the liquid oxygen and methane tank structure, SpaceX engineers and technicians will additionally have to complete the vehicle’s aft section, a massive 9m/30ft-diameter thrust structure capable of supporting the thrust of three Raptor engines and the weight of the entire fueled rocket. After that, plumbing, avionics, sensors, attitude thrusters, and more will still need to be completed and integrated.
If Starhopper’s nose section is largely a nonfunctioning aerodynamic shroud and propellant tanks will be primarily located inside the aft section, the fuel and oxidizer capacities of the vehicle’s tanks can be roughly estimated. Assuming a 9m/30ft diameter, the aft barrel stands around 13m/43ft tall. Assuming that the upper tank dome will reach a meter or two above the steel cylinder and that the aft Raptor thrust structure is also roughly 1-2 meters deep, Starhopper would have a total tank volume around 830 m3 or almost 30,000 cubic feet (~225,000 gallons), potentially 1000 metric tons of fuel or more if fully loaded.

Perhaps less than coincidentally, SpaceX already has liquid methane and oxygen tanks on-site (one is pictured above) with more than enough capacity to meet Starhopper’s potential propellant needs. However, it’s worth noting that current plans (and permissions) only show Starhopper traveling as high as 5km on flights that will last no more than 6 minutes, and CEO Elon Musk has indicated in no uncertain terms that the prototype will remain distinctly suborbital and is primarily focused on fleshing out Starship’s vertical take-off or landing (VTOL) capabilities before SpaceX proceeds to much more aggressive tests.
While it would be safe to take his schedule with many dozens of grains of salt, Musk noted last week that the first orbit-ready Starship could be finished as early as June 2019, while he expects Starhopper tests to begin as early as February or March. Where exactly that orbital Starship and its Super Heavy booster partner will be built is now much less clear after SpaceX has reportedly canceled a berth lease and thus its plans to build a BFR factory in the Port of Los Angeles. Will SpaceX build a BFR factory in Texas or will it build the orbital Starship en plein air like its Starhopper predecessor? And Super Heavy? Where will all three conduct static fires, hops, or launches from?
Stay tuned as more details and photos continue to bubble up from beneath the surface.
Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.
The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.
🚨 The design uses electrically driven ducted fans, typically shown as a row of four at the rear, powered by the vehicle’s high-voltage battery.
The fans pull air from an underbody inlet, route it through ducts, and expel it from a larger rear outlet that functions as a… https://t.co/CHQB9u9UA3 pic.twitter.com/QVXmWTdggh

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.
Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.
The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.
The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.
Tesla Roadster event requires restricted airspace, and the FAA obliges
The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.
There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.
These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.
Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.
It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.
Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.
Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.
Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.
I’m at Tesla right now and when I walked into their showroom I was shocked to see it basically empty.
I asked one of the people working there where all of the cars are “Gone – it’s the end of the quarter and we’ve sold out of everything… including the display vehicles”So… pic.twitter.com/rN7s3gE6sJ

All the cars are gone from Tesla Century City!
All they have is Model Y L, a self-driving video playing on the background. I guess the best product is no product. Either that or they just sold the showroom cars. pic.twitter.com/mzCjWaXwww

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.
Talking to the guys at the Mechanicsburg showroom on Friday, they couldn’t believe they had ANOTHER hauler coming in of cars for delivery—and each was accounted for
No car just sitting in inventory. They’re expecting a BIG quarter, and this is more than just the Y L https://t.co/ce801GkKVv

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.
In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.
Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.

Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.
Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”
The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.

The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.
Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.
Tesla plans big safety improvements for Full Self-Driving v15
Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.
Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.
