SpaceX ‘tops off’ its South Texas Starship prototype with one final steel dome
On September 14th, South Texas SpaceX technicians lifted Starship Mk1’s third and final tank dome and began to attach it atop the prototype’s steel tank section, this time making use of a new method of integration.
This progress comes just two weeks before CEO Elon Musk is expected to present a detailed update on Starship’s newest design iteration. Musk is hopeful that – come his September 28th presentation – Starship Mk1 will be nearly complete and ready for its inaugural flight, a milestone that could come as early as October 13th according to Starship documents filed with the FCC.
This latest installation is likely either the last ring (or nearly so) to be stacked on top of Starship Mk1, paving the way for the eventual attachment of the spacecraft’s conical nose section and the fleshing out of its many internal subsystems and aerodynamic control surfaces. This particular milestone involved the attachment of Starship’s third and final tank bulkhead – in this case, the upper dome of the prototype’s liquid oxygen tank. Excluding hardware that might eventually be installed on the dome itself, this means that Starship Mk1’s tank and engine section has essentially been ‘topped off’.
As previously estimated by the author, this particular tank dome installation – the fifth completed by SpaceX’s Mk1 and Mk2 Starship teams – was done in a manner thus far unique. All previous installations have seen SpaceX technicians lower the domes – completed aside from one vertical weld for flexibility – inside the Starship’s cylindrical tank section. The steel domes are then carefully spot-welded to the side of the tank in their proper place – all while being supported by a large crane – before technicians can complete a seamless ring weld around their entire circumference.
This time around, SpaceX welded the upper tank dome to its companion ring section while both elements were still staged on the ground. Once the dome was completely welded to the steel ring and a dome cap was installed to seal off the top, the ring segment was craned atop Starhip Mk1 on September 14th. It’s possible that this was planned all along for each Starship’s third and final tank dome, but the way CEO Elon Musk has previously described SpaceX’s semi-competitive Mk1 and Mk2 builds suggests that it may instead be a new assembly strategy that evolved in just the last month or two.
Instead of having to do the work of fitting, attaching, and ring-welding the bulkhead to Starship’s tank section 50-100 feet above ground, with all the associated rigging, scaffolding, and challenges such a work environment demands, technicians were able to do the majority of that work at ground-level. This method seems to offload the added challenge of dome installation to the vertical ring installation process, effectively merging the two processes into one much simpler (and safer) feat.
The fact that Starship Mk1’s tank section has now been capped (aside from several small access ports) indicates that all large, plumbing-related components have been installed inside the steel prototype. Up next for Starship Mk1 is the installation of its landing legs/fins/wings (at least two of which have already arrived on-site), canards, and a variety of smaller additions like valves, thrusters, ground connection points, and much more.

Tesla one-ups Waymo once again with latest Robotaxi expansion in Austin
Tesla’s new Robotaxi geofence measures roughly 171 square miles of Austin’s downtown and suburbs. This is more than double the size of Waymo’s geofence, which measures 90 square miles.

Tesla’s expansion of the Robotaxi geofence on Tuesday morning was a one-up on Waymo once again, as the automaker’s service area growth helps eclipse its rival in an intense back-and-forth.
A lot of conversation has been made about Tesla’s rivalry with Waymo in terms of the capabilities of its driverless ride-sharing service in Austin, Texas.
The two companies have sparred with one another, answering each other’s expansion, and continuing to compete, all to the benefit of consumers in the region.
Tesla expanded the geofence of Robotaxi once again this morning, and it is another growth that catapults it past Waymo’s service area in Austin — this time by a considerable margin.

Tesla’s new Robotaxi geofence measures roughly 171 square miles of Austin’s downtown and suburbs. This is more than double the size of Waymo’s geofence, which measures 90 square miles.
On July 14, Tesla officially overtook Waymo in terms of service area in Austin. But just a few days later, Waymo had responded with a bold statement, expanding from 37 square miles to 90 square miles.
Sarfraz Maredia, Global Head of Autonomous Mobility & Delivery at Uber, said the move “unlock[ed] another key milestone in Austin as our operating territory with Waymo expands from 37 to 90 square miles, which means that even more riders can experience Waymo’s fully autonomous vehicles through the Uber app.”
Tesla did not respond immediately, but it took its time with validation vehicle testing in the Austin suburbs, as we reported yesterday:
Tesla looks to expand Robotaxi geofence once again with testing in new area
Today’s expansion is perhaps the biggest step Tesla has taken in its efforts to continue to grow its Robotaxi platform. This is not only because the company has significantly expanded the size of the geofence, but also because it has ventured into suburban areas and even included Gigafactory Texas in its service area.
Waymo could come up with another timely response as it did when Tesla expanded in late July. We’ll wait to see what it comes up with, as this awesome competition between the two companies is accelerating innovation.

Tesla Robotaxi geofence expansion enters Plaid Mode and includes a surprise
Now, on August 26, the Robotaxi geofence has expanded once again, and is estimated to be about 130 square miles.

Tesla has expanded its Robotaxi geofence in Austin for the third time since its launch in late June, and the company added a big surprise with this new service area.
After launching on June 22, Tesla’s driverless Robotaxi service has been expanded three times. Its initial launch was about 20 square miles in size. The first expansion occurred on July 14 and was roughly 42 miles large, more than double the initial geofence size.
The second expansion occurred on August 3 and brought the total service area to roughly 80 square miles.
Now, on August 26, the Robotaxi geofence has expanded once again, and is estimated to be about 170 square miles.

The expansion of the Robotaxi geofence seemed to show the company’s focus on getting the service to the areas East and West of downtown was an utmost priority.
We reported on the Bee Cave region of the Austin suburbs being a place where Robotaxi validation vehicles were spotted testing in recent days.
Bee Cave is included in the new geofence.
However, that is not the biggest addition to the geofence, and it’s not even close. Tesla added a major area to the new geofence, one that fans of the company will absolutely love: Tesla Gigafactory Texas.

The big question that remains is whether Tesla is expanding the size of its fleet of Robotaxi vehicles in Austin. There have been many questions about the expansions of the fleet and not necessarily the geofence, and while the latter is certainly considered progress, Tesla will need to enable more Robotaxi into the vehicle population to handle the additional rides.
Tesla has been planning to do so, but is still prioritizing safety and does not want to rush any part of the Robotaxi process.
Tesla is also looking to expand to new cities altogether. It is currently moving toward a Robotaxi launch in Florida, Arizona, and Nevada, and has also opened up job postings for Robotaxi operators in New York.

Elon Musk reiterates his most optimistic prediction yet with “UHI” forecast
Despite his polarizing nature, Elon Musk is, at his core, an optimist.

Despite his polarizing nature, Elon Musk is, at his core, an optimist. If he were not one, he would never have founded Tesla or SpaceX, or pursued projects such as Neuralink or xAI.
Musk’s optimism was on full display on social media platform X recently, when he shared what could very well be his most optimistic prediction yet.
Robots and humans
The Tesla CEO recently responded to a post from David Scott Patterson, who estimated that all jobs will be replaced by AI and robots easily by 2030. In his post, Patterson noted that if robots are sold at the same rate as vehicles, it could result in an output of 320 million robots per year.
Musk responded that eventually, intelligent humanoid robots will far exceed the population of humans, and “there will be many robots in industry for every human to provide products & services.”
Musk is already taking steps to achieve such a future. Tesla’s Optimus humanoid robot is expected to see its first “legion” produced this 2025. During an All-Hands meeting earlier this year, Musk also hinted to Tesla employees that the company will try to produce about 50,000 Optimus robots next year.
Universal High Income (UHI)
Musk has shared similar sentiments in the past, so it was no surprise that some X users asked the CEO how humans could sustain their lives when robots replace working individuals. To this, Musk responded that a Universal High Income (UHI) would be implemented, which should provide people with the best medical care, food, and transport available.
“There will be universal high income (not merely basic income). Everyone will have the best medical care, food, home, transport and everything else. Sustainable abundance,” Musk wrote in his post.
Musk’s comment about sustainable abundance seems to be a prevalent theme in his recent optimistic comments. During Tesla’s second quarter earnings call, for example, Musk hinted that his Master Plan Part Four will describe a path towards sustainable abundance in a post-autonomy world.
