SpaceX Starship briefly becomes largest rocket in history – now what’s next?

On August 6th, after a great deal of anticipation, SpaceX stacked a Starship on top of a Super Heavy booster for the first time ever, very briefly assembling the largest rocket in history.

However, barely an hour after the two stages were integrated and (presumably) latched together, SpaceX lifted Starship (S20) off the booster, returned it to its transport stand, and rolled the ship back to the build site later that day. Though an extreme sensitivity to wind conditions has delayed the procedure, Super Heavy Booster 4 (B4) also appears to be on track to be removed from the orbital launch mount and sent either back to the factory or to a suborbital launch mount that’s been modified for booster testing.

For those that followed the process closely in the days and weeks prior, the fact that Starship’s first full assembly was just a fit check (and, really, more like 50:50 between fit check and photo op) came as no surprise. In the lead-up, it became clear through several reports that CEO Elon Musk had challenged SpaceX to stack Ship 20 and Booster 4 by August 5th and flown in several hundred employees normally stationed elsewhere to accomplish the feat.

Ignoring weather delays that prevented stacking on August 5th, SpaceX met Musk’s challenge in all but the literal sense, assembling the world’s largest rocket into one integrated stack for the first time ever. Even more significantly, despite the fact that SpaceX could have easily decided to stack two not-for-flight prototypes to sort of achieve the same feat, both stages – Ship 20 and Booster 4 – involved in the August 6th milestone are nominally destined for flight.

Barring surprises, the same exact pair is scheduled to support Starship’s first orbital test flight as early as this year. Before they can be cleared for flight, however, a great deal of work must still be completed – work that in some cases is unprecedented in the history of the Starship program.

Not long after the stacking milestone, Musk himself sketched out a few of the tasks still in front of the rocket. Namely, Musk says that SpaceX must still complete Starship S20’s partially-finished heat shield, install some form of heat shield(s) to protect Super Heavy Booster 4’s 29 naked Raptor engines; finish installing, plumbing, and activating 4-7 massive custom propellant storage tanks; and assemble, install, and activate a giant mechanical umbilical arm on the launch tower to fuel and power Starship.

All are undoubtedly crucial and Starship is unlikely to launch before any of them are more or less complete. However, the booster and ship themselves are arguably far more of a pressure point. Before they can be deemed ready for flight, both the ship and booster must complete unprecedented test campaigns on the ground.

Ship 20 will need to complete cryogenic proof testing to verify that the first Starship with six Raptor engine mounts is structurally sound. SpaceX has already modified one of its two suborbital Starship launch mounts for that purpose. Once cryo proof and hydraulic ram testing is complete, those six rams will likely be removed and six Raptor engines will be installed in their place, potentially setting up Ship 20 to become the first Starship prototype to static fire six engines – and any number of Raptor Vacuum engines.

Super Heavy Booster 4 will be faced with an even more ambitious static fire test campaign as SpaceX likely gradually installs more and more engines. Depending on how focused SpaceX is on speed over thoroughness, that process could involve gradually adding 2-5 engines after every static fire or could result in SpaceX starting with 4-9 engines and then immediately jumping from 9 to a full 29-Raptor static fire.

Only after completing those crucial qualification tests is SpaceX likely to stack Ship 20 and Booster 4 for a second time and enter the first true full-stack Starship launch flow – hopefully culminating in the first orbital launch attempt later this year, but only as soon as the FAA completes an environmental review and approves the rocket’s launch license. Technically, FAA approval could come next month or it could take the agency a year or more – it’s almost impossible to predict without official information. However, given SpaceX’s track record with Starship prototypes and Booster B3, it’s likely that a flightworthy Starship and Super Heavy will be stacked on the pad and ready to launch just a few months from now.

Jim Farley admits he was “humbled” when Ford tore down Tesla and Chinese EVs

He noted that Ford’s Mustang Mach-E had roughly 1.6 kilometers more electrical wiring than Tesla’s sedan, making it heavier and more expensive to build.

Ford CEO Jim Farley says dismantling Tesla and Chinese-made EVs was a wake-up call that reshaped how the veteran automaker is taking on the electric transition. 

Speaking on the Office Hours: Business Edition podcast, Farley admitted he was “humbled” after learning how far ahead Tesla and China’s automakers were in design and efficiency. The revelation, he stated, convinced him that Ford had to rethink everything from engineering to strategy.

Teardowns and tech gaps

“I was very humbled when we took apart the first Model 3 Tesla and started to take apart the Chinese vehicles. When we took them apart, it was shocking what we found,” Farley told host Monica Langley, as noted in an Insider report. 

He noted that Ford’s Mustang Mach-E had roughly 1.6 kilometers more electrical wiring than Tesla’s sedan, making it heavier and more expensive to build.

The experience pushed Farley to launch Ford’s Model e in 2022, a dedicated EV division focused on competing with tech-driven automakers. Although Model e lost more than $5 billion in 2024 and is expected to face similar losses this year, Farley said he has no regrets.

“I knew it was going to be brutal business-wise. My ethos is, take on the hardest problems as fast as you can and sometimes do it in public because you’ll solve them quicker that way,” he said.

Farley has led Ford since 2020, during which he’s pushed the company to adopt leaner designs, modernized software systems, and faster EV production cycles inspired by Tesla’s model.

Urgency in Ford’s global push

Farley has repeatedly warned that Chinese EV makers such as BYD now pose an “existential threat” to legacy carmakers. He described Chinese electric vehicles as “far superior” and said their expansion overseas highlights how quickly the landscape is changing. 

“We can’t walk away from EVs,” Farley said. “Not just for the US, but if we want to be a global company, I’m not going to just cede that to the Chinese.”

Still, the U.S. market remains challenging. Farley expects only about 5% of domestic car sales to be electric in the near term, as buyers demand more affordable models. To meet that shift, Ford plans a $30,000 midsize electric truck for 2027.

“We now know that the EV market in the US is totally different than we thought,” Farley stated.

Tesla has reached a major milestone in Australia, celebrating 150,000 vehicles on local roads. 

The milestone was announced by the electric vehicle maker on social media platform X.

Sustainability for all

In its post on X, Tesla Australia and New Zealand noted that the 150,000-vehicle milestone is a notable accomplishment as it accelerates “sustainable abundance for all.” The company also thanked its customers down under for supporting its vehicles over the years.

“Accelerating sustainable abundance for all. Celebrating 150k Teslas on the road. Thank you, Australia,” Tesla Australia and New Zealand wrote in its post on X.

The post was accompanied by a photo of what appeared to be a Quicksilver Model Y premium with the Sydney Opera House in the background. This is an appropriate photo for the EV maker, as the Model Y consistently ranks among Australia’s top-selling electric cars, even as the market becomes flooded with cheaper, newer, and flashier competitors.

Australia’s FSD momentum

Last month, Tesla revealed that FSD Supervised users in Australia and New Zealand have collectively driven over 1 million kilometers within two weeks of the system’s public release. The company noted that drivers are averaging around 80,000 kilometers per day with FSD Supervised active, equivalent to 67 laps around Australia or 625 trips from Auckland to Invercargill.

“In less than 2 weeks, owners have travelled 1 million kilometers on FSD Supervised in AU & NZ,” Tesla’s local account wrote.

Australia became the first right-hand-drive market to gain access to FSD Supervised, which was officially launched in the country on September 18. Coupled with the presence of FSD (Supervised) subscriptions, the adoption of FSD in Australia has been understandably quick.
