Elon Musk says SpaceX’s second Starship booster prototype is almost finished
SpaceX CEO Elon Musk says that the second Starship booster prototype is “almost done” and has revealed that work on the first flightworthy booster has yet to begin.
For unknown reasons, SpaceX has recently changed the naming scheme for Starship and Super Heavy boosters. The booster SpaceX is currently assembling in Boca Chica has been referred to as “Booster 2” by Musk himself but, according to NASASpaceflight, is internally known as Booster 3 or B3, replacing its former Booster Number 3 (BN3) designation.
Regardless, SpaceX began stacking the Super Heavy booster prototype now known as B3 in mid-May. Around six weeks later, 23 or 24 rings have been stacked to create a partially finished prototype 9m (~30 ft) wide and approximately 42m (~140 ft) tall.
Just like Super Heavy ‘pathfinder’ BN1, which was scrapped almost the instant it reached its full height last March, Booster 3 appears to destined to stand 36 rings – 65m (~215 ft) – tall once complete. While drastically oversimplifying the process of vertically assembling the largest rocket booster ever built, that means that Super Heavy B3 is just shy of two-thirds (~65%) complete.
By simply averaging the time it’s taken for SpaceX to stack B3 to a height of 42 meters, the booster could reach its full height around three weeks from now (July 15th, give or take a week). For the most part, the most challenging and unfamiliar parts of Super Heavy B3 manufacturing and assembly have already been completed. Relative to Starship, which SpaceX has now built more than half a dozen prototypes of, Super Heavy is just a stretched Starship with no flaps, no nosecone, a far more complex engine section, and a forward dome section that needs to support car-sized grid fins.
Super Heavy’s larger propellant tanks also require a methane transfer tube – used to carry methane through the booster’s lower liquid oxygen tank – more than twice as tall as anything built for Starship. By all appearances, that ~35m (~115 ft) tall transfer tube has already been safely installed inside B3’s incomplete tanks. Around June 14th, B3’s lower two-thirds were effectively completed when its LOx tank stack was mated to the booster’s 29-Raptor engine section.
Outfitted with complex structural modifications to support massive grid fins and the first advanced ‘hot gas’ maneuvering thrusters ever spotted in public, Booster 3’s forward dome is already in the process of being welded to a stack of three steel rings. Once complete, the rest of Super Heavy B3 integration is fairly simple as far as rocket assembly goes and will require four more welding operations. Like BN1, there’s a good chance that SpaceX will mate Booster 3’s upper (methane) tank separately and then install the ~24m (~80 ft) tall, 13-ring section on top of the LOx stack to effectively complete the booster’s main structure
Of course, after the structure is complete, SpaceX will still need to finish plumbing, wiring, and generally outfitting a Super Heavy booster for the first time ever. Finally, while it remains to be seen just how finished B3 will actually find itself before heading to the launch pad, that process could also involve installing and testing four massive steel grid fins and, most importantly, up to 29 Raptor engines – a figure only beaten by the Soviet Union’s ill-fated N1 rocket.
Perhaps most significantly, Musk also revealed that B3 is not the Super Heavy booster assigned to Starship’s first orbital launch attempt, meaning that SpaceX will have to complete Booster 3 testing and build Booster 4 before that orbital test flight can occur. Given that Booster 3 assembly is on track to take more than nine weeks, Starship’s first orbital launch attempt is thus unlikely to happen before late August or September.

Elon Musk confirms Tesla Cybercab pricing and consumer release date
Elon Musk has confirmed that Tesla does intend to sell a version of the Cybercab for less than $30,000 by 2027.
Elon Musk has confirmed that Tesla does intend to sell a version of the Cybercab for less than $30,000 by 2027. He shared the update in a post on social media platform X.
Amidst Tesla’s announcement that the first Cybercab has been produced at Giga Texas’ production line, some members of the Tesla community immediately started joking about how the milestone will affect a wager shared by popular YouTube tech reviewer Marques Brownlee (MKBHD.)
Following Tesla’s We, Robot event in October 2024, MKBHD noted that while the Cybercab was impressive in a lot of ways, he is very skeptical about Elon Musk’s estimate that the autonomous two-seater could be sold to consumers for below $30,000 around 2027.
“I think the obvious red flag, the biggest red flag to me is the timeline stuff. This is notorious Elon stuff. He gets on stage, he says we’re going to have this vehicle out for $30,000 before 2027,” he said, adding “No, they’re not. There’s just no way that they’re actually going to be able to do that. I mean, if they do, let’s say they do, I will shave my head on camera because I’m that confident.”
It was then no surprise that meme images of MKBHD with his head shaved immediately spread on X following Tesla’s announcement that the first Cybercab has been built at Giga Texas. One of these, which was posted by longtime FSD tester Whole Mars Catalog, received a response from Elon Musk. The CEO responded with the words “Gonna happen,” together with a laughing emoji.
Apart from riding jokes about MKBHD’s wager, Musk also confirmed that Tesla will be selling a Cybercab to regular consumers before 2027, and the vehicle will be priced for $30,000 or less. In response to an X user who asked if the exact scenario will be happening, Musk responded with a simple “Yes.”
While the first Cybercab has been produced at Giga Texas, it would not be surprising if the following months will only see low volumes of the autonomous two seater being produced. As per Elon Musk in previous comments, the Cybercab’s early production will likely be slow, but it will eventually be extremely fast. “For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast,” he said.

First Tesla Cybercab rolls off Giga Texas production line
Tesla’s official account on X shared an image showing employees gathered around the first Cybercab built at Gigafactory Texas.
Tesla has produced the first Tesla Cybercab at Texas Gigafactory, marking a key milestone ahead of the planned autonomous two-seater’s production in April. The two-seat Robotaxi, which was unveiled in 2024, is designed without pedals or a steering wheel and represents Tesla’s most aggressive step yet toward fully autonomous mobility.
Tesla’s official account on X shared an image showing employees gathered around the first Cybercab built at Gigafactory Texas. Elon Musk echoed the milestone, writing, “Congratulations to the Tesla team on making the first production Cybercab!”
Previous comments from Musk on X reiterated the idea that production of the Cybercab “starts in April.” The vehicle will launch without traditional driver controls, and it will rely entirely on Tesla’s vision-based Full Self-Driving (FSD) system.
The Cybercab is positioned to compete with autonomous services such as Waymo. While Tesla has deployed Model Y vehicles in limited Robotaxi operations in Austin and the Bay Area, a serious ramp of the service to other cities across the United States is yet to be implemented. The production of the Cybercab could then be seen as a push towards the company’s autonomy plans.
Musk has linked the Cybercab to Tesla’s proposed “Unboxed” manufacturing process, which would assemble large vehicle modules separately before integrating them, rather than following a traditional production line. The approach is intended to cut costs, reduce factory footprint, and speed up output.
That being said, Elon Musk has set expectations for the Cybercab’s production ramp. As per Musk, it would likely take some time before meaningful volumes of the Cybercab are produced because it is such a new and different vehicle. But when the vehicle hits its pace, volumes will be notable.
“Initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast,” Musk noted.

California city weighs banning Elon Musk companies like Tesla and SpaceX
A resolution draft titled, “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies,” alleges that Musk “has engaged in business practices that are alleged to include violations of labor laws, environmental regulations, workplace safety standards, and regulatory noncompliance.”
A California City Council is planning to weigh whether it would adopt a resolution that would place a ban on its engagement with Elon Musk companies, like Tesla and SpaceX.
The City of Davis, California, will have its City Council weigh a new proposal that would adopt a resolution “to divest from companies owned and/or controlled by Elon Musk.”
This would include a divestment proposal to encourage CalPERS, the California Public Employees Retirement System, to divest from stock in any Musk company.
A resolution draft titled, “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies,” alleges that Musk “has engaged in business practices that are alleged to include violations of labor laws, environmental regulations, workplace safety standards, and regulatory noncompliance.”
It claims that Musk “has used his influence and corporate platforms to promote political ideologies and activities that threaten democratic norms and institutions, including campaign finance activities that raise ethical and legal concerns.”
If adopted, Davis would bar the city from entering into any new contracts or purchasing agreements with any company owned or controlled by Elon Musk. It also says it will not consider utilizing Tesla Robotaxis.

A staff report on the proposal claims there is “no immediate budgetary impact.” However, a move like this would only impact its residents, especially with Tesla, as the Supercharger Network is open to all electric vehicle manufacturers. It is also extremely reliable and widespread.
Regarding the divestment request to CalPERS, it would not be surprising to see the firm make the move. Although it voted against Musk’s compensation package last year, the firm has no issue continuing to make money off of Tesla’s performance on Wall Street.
The decision to avoid Musk companies will be considered this evening at the City Council meeting.
The report comes from Davis Vanguard.
It is no secret that Musk’s political involvement, especially during the most recent Presidential Election, ruffled some feathers. Other cities considered similar options, like the City of Baltimore, which “decided to go in another direction” after awarding Tesla a $5 million contract for a fleet of EVs for city employees.
