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?

Tesla is reportedly preparing to launch a Robotaxi pilot program in the Bay Area this weekend, with invites to a select number of customers reportedly being sent out as early as this Friday.

The update was shared in a report from Insider, which cited an internal memo from the electric vehicle maker.

New Robotaxi service launch

According to Insider, the Robotaxi service in the Bay Area is set to launch as soon as Friday. Thus, some Tesla owners in the area should receive invites to use the driverless ride-hailing service. Similar to the Austin pilot, the Robotaxi rides will reportedly be a paid service.

The publication noted that the Robotaxi service’s geofence in its Bay Area launch will be quite large, as it will include Marin, much of the East Bay, San Francisco, and San Jose. This is not surprising as California has long been saturated with Teslas, and it is home to several of the electric vehicle maker’s key facilities.

Unlike the Austin pilot, the Tesla Robotaxi service’s pilot in the Bay Area will use safety drivers seated in the driver’s seat. These drivers will be able to manually take over using the steering wheel and brakes as needed. As per a spokesperson from the California DMV, the agency recently met with Tesla but the company is yet to submit a formal application to operate fully driverless cars.

Tesla Robotaxi expansion

Interestingly enough, Tesla did tease the release of its Robotaxi service to the Bay Area in its second quarter earnings call. While discussing the service, Tesla VP of Autopilot/AI Software Ashok Elluswamy mentioned that the company will initially be rolling out Robotaxis with safety drivers in the San Francisco Bay Area. He did, however, also highlight that the electric vehicle maker is working hard to get government permission to release the service for consumers.

“The next thing to expand would be in the San Francisco Bay Area. We are working with the government to get approval here and, in the meanwhile, launch the service without the person in the driver seat just to expedite and while we wait for regulatory approval,” he stated.

Tesla is ready with a perfect counter to the end of US EV tax credits

Tesla executives have mentioned that these more affordable models would resemble the company’s current lineup.

The United States’ electric vehicle tax credit is coming to an end at the end of the third quarter. Tesla, the country’s leading electric vehicle maker, is ready to meet this challenge with a rather simple but clever counter. 

Tesla executives outlined this strategy in the recently held Q2 2025 earnings call.

End of the US EV tax credit

While Elon Musk has always maintained that he prefers a market with no EV tax credit, he also emphasized that he supports the rollback of any incentives given to the oil and gas industry. The Trump administration has not done this so far, instead focusing on the expiration of the $7,500 EV tax credit at the end of the third quarter.

Tesla has been going all-in on encouraging customers to purchase their vehicles in Q3 to take advantage of lower prices. The company has also implemented a series of incentives across all its offerings, from the Cybertruck to the Model 3. This, however, is not all, as the company seems to be preparing a longer-term solution to the expiration of the EV tax credit.

Affordable variants

During the Q2 2025 earnings call, Vice President of Vehicle Engineering Lars Moray stated that Tesla really did start the production of more affordable models in June. Quality builds of these vehicles are being ramped this quarter, with the goal of optimizing production over the remaining months of the year. If Tesla is successful, these models will be available for everyone in Q4.

“We started production in June, and we’re ramping quality builds and things around the quarter. And given that we started in North America and our goal is to maximize production with a higher rate. So starting Q3, we’re going to keep pushing hard on our current models to avoid complexity… We’ll be ready with new, more affordable models available for everyone in Q4.,” Moravy stated. 

These comments suggest that Tesla should be able to offer vehicles that are competitively priced even after the EV tax credit has been phased out. Interestingly enough, previous comments from Tesla executives have mentioned that these more affordable models would resemble the company’s current lineup. This suggests that the more affordable models may indeed be variations of the Model Y and Model 3, but offered at a lower price.

Elon Musk reveals Tesla’s next Robotaxi expansion in more ways than one

Tesla Robotaxi is growing in more ways than one. Tesla wants to expand and hopes to reach half the U.S. population by the end of the year.

Tesla CEO Elon Musk revealed the company’s plans for its next expansion of the Robotaxi in terms of both the geofence in Austin and the platform overall, as it looks to move to new areas outside of Texas.

Tesla launched the Robotaxi platform last month on June 22, and has since expanded both the pool of users and the area that the driverless Model Y vehicles can travel within.

The first expansion of the geofence caught the attention of nearly everyone and became a huge headline as Tesla picked a very interesting shape for the new geofence, resembling male reproductive parts.

The next expansion will likely absolve this shape. Musk revealed last night that the new geofence will be “well in excess of what competitors are doing,” and it could happen “hopefully in a week or two.”

Musk’s full quote regarding the expansion of the geofence and the timing was:

“As some may have noted, we have already expanded our service area in Austin. It’s bigger and longer, and it’s going to get even bigger and longer. We are expecting to greatly increase the service area to well in excess of what competitors are doing, hopefully in a week or two.”

The expansion will not stop there, either. As Tesla has operated the Robotaxi platform in Austin for the past month, it has been working with regulators in other areas, like California, Arizona, Nevada, and Florida, to get the driverless ride-hailing system activated in more U.S. states.

Tesla confirmed that they are in talks with each of these states regarding the potential expansion of Robotaxi.

Musk added:

“As we get the approvals and prove out safety, we will be launching the autonomous ride-hailing across most of the country. I think we will probably have autonomous ride-hailing in probably half the population of the US by the end of the year.”

We know that Tesla and Musk have been prone to aggressive and sometimes outlandish timelines regarding self-driving technology specifically. Regulatory approvals could happen by the end of the year in several areas, and working on these large metros is the best way to reach half of the U.S. population.

Tesla said its expansion of the geofence in Austin is conservative and controlled due to its obsession with safety, even admitting at one point during the Earnings Call that they are being “paranoid.” Expanding the geofence is necessary, but Tesla realizes any significant mistake by Robotaxi could take it back to square one.
