SpaceX CEO Elon Musk says Starship could be followed by a dramatically larger rocket
Hinted at in a brief tweet on August 28th, SpaceX CEO Elon Musk says that SpaceX’s massive Starship and Super Heavy launch vehicle – set to be the most powerful rocket ever built upon completion – could eventually be followed by a rocket multiple times larger.
SpaceX is currently in the process of assembling the first full-fidelity prototypes of Starship, a 9m (30 ft) diameter, 55m (180 ft) tall reusable spacecraft and upper stage. Two prototypes – Mk1 and Mk2 – are simultaneously being built in Texas and Florida, respectively, while the beginnings of the first Super Heavy prototype has visibly begun to take shape at SpaceX’s Florida campus.
Once complete, Starship’s Super Heavy booster will be the single most powerful rocket booster ever built, standing at least 70m (230 ft) tall on its own and capable of producing as much as ~90,000 kN (19,600,000 lbf) of thrust with 30 250-ton-thrust and 7 200-ton-thrust Raptor engines installed. Assuming 31 throttleable 200-ton Raptors, Super Heavy’s minimum max thrust is a still record-breaking ~62,000 kN (13.7 million lbf).
In fewer words, a full Starship/Super Heavy ‘stack’ would be the tallest (~118m/390ft), heaviest (~5000 tons/11 million lbs), and most powerful rocket ever assembled.
And yet, despite its size, orbital-class rocketry in Earth gravity will almost never fail to benefit from more thrust; more propellant; more rocket. In light of this, CEO Elon Musk says that a theoretical next- next-generation SpaceX rocket – to potentially follow some years after Starship and Super Heavy – could be a full 18m (60 ft) wide, twice the diameter of its predecessors.
Many will recollect that doubling the diameter of a circle quadruples its area. Add in a doubling of height and a theoretical Starship 2.0 would have eight times the surface area and eight times the propellant tank volume, requiring roughly eight times as much thrust and making the vehicle eight times as heavy as Starship 1.0. Assuming that Starship’s successor retains its fineness ratio (height/width), an unlikely end result but still interesting to ponder, the vehicle would measure 18m (60 ft) in diameter and a terrifying ~236m (780 ft) tall, literally more than twice as tall as Saturn V. An 18m diameter would also make it the widest rocket ever built, with Saturn V’s S-IC first stage measuring 10m wide and the Soviet Union’s N1 ‘Block A’ first stage measuring an impressive ~17m in diameter at its widest point.
If the above assumptions are correct, a very rough estimate would peg Starship 2.0’s gross (fueled) mass at a gobsmacking ~40,000 metric tons (~90 million pounds). In the unlikely event that SpaceX would use the current generation of Raptor to power such a colossal rocket, the booster would need a bare minimum of 100+ Raptors just to lift off at all. Using Saturn V’s F-1, still the most powerful single-chamber rocket engine ever built, Starship 2.0 would need a minimum of 60+ engines to lift off.
For the time being, Starship and Super Heavy are plenty ambitious on their own, but it’s unsurprising to hear that SpaceX CEO Elon Musk already has some thoughts on what could follow that next-generation launch vehicle in the new decade. Still, it’s worth noting that quite possibly the craziest aspect of Starship – SpaceX’s utterly non-traditional attempt at rewriting the book on rocket manufacturing – could eventually make an 18m-diameter vehicle far more practical, assuming the company proves it’s methods can be used to build reliable, high-performance rockets.

Tesla Robotaxi ride-hailing without a Safety Monitor is proving to be a difficult task, according to some riders who made the journey to Austin to attempt to ride in one of its vehicles that has zero supervision.
Last week, Tesla officially removed Safety Monitors from some — not all — of its Robotaxi vehicles in Austin, Texas, answering skeptics who said the vehicles still needed supervision to operate safely and efficiently.
BREAKING: Tesla launches public Robotaxi rides in Austin with no Safety Monitor
Tesla aimed to remove Safety Monitors before the end of 2025, and it did, but only to company employees. It made the move last week to open the rides to the public, just a couple of weeks late to its original goal, but the accomplishment was impressive, nonetheless.
However, the small number of Robotaxis that are operating without Safety Monitors has proven difficult to hail for a ride. David Moss, who has gained notoriety recently as the person who has traveled over 10,000 miles in his Tesla on Full Self-Driving v14 without any interventions, made it to Austin last week.
He has tried to get a ride in a Safety Monitor-less Robotaxi for the better part of four days, and after 38 attempts, he still has yet to grab one:
Wow just wow!
It’s 8:30PM, 29° out ice storm hailing & Tesla Robotaxi service has turned back on!
Waymo is offline & vast majority of humans are home in the storm
Ride 38 was still supervised but by far most impressive yet pic.twitter.com/1aUnJkcYm8

Tesla said last week that it was rolling out a controlled test of the Safety Monitor-less Robotaxis. Ashok Elluswamy, who heads the AI program at Tesla, confirmed that the company was “starting with a few unsupervised vehicles mixed in with the broader Robotaxi fleet with Safety Monitors,” and that “the ratio will increase over time.”
This is a good strategy that prioritizes safety and keeps the company’s controlled rollout at the forefront of the Robotaxi rollout.
However, it will be interesting to see how quickly the company can scale these completely monitor-less rides. It has proven to be extremely difficult to get one, but that is understandable considering only a handful of the cars in the entire Austin fleet are operating with no supervision within the vehicle.
Tesla has given its biggest hint that Full Self-Driving in Europe is imminent, as a new feature seems to show that the company is preparing for frequent border crossings.
Tesla owner and influencer BLKMDL3, also known as Zack, recently took his Tesla to the border of California and Mexico at Tijuana, and at the international crossing, Full Self-Driving showed an interesting message: “Upcoming country border — FSD (Supervised) will become unavailable.”
FSD now shows a new message when approaching an international border crossing.

Due to regulatory approvals, once a Tesla operating on Full Self-Driving enters a new country, it is required to comply with the laws and regulations that are applicable to that territory. Even if legal, it seems Tesla will shut off FSD temporarily, confirming it is in a location where operation is approved.
This is something that will be extremely important in Europe, as crossing borders there is like crossing states in the U.S.; it’s pretty frequent compared to life in America, Canada, and Mexico.
Tesla has been working to get FSD approved in Europe for several years, and it has been getting close to being able to offer it to owners on the continent. However, it is still working through a lot of the red tape that is necessary for European regulators to approve use of the system on their continent.
This feature seems to be one that would be extremely useful in Europe, considering the fact that crossing borders into other countries is much more frequent than here in the U.S., and would cater to an area where approvals would differ.
Tesla has been testing FSD in Spain, France, England, and other European countries, and plans to continue expanding this effort. European owners have been fighting for a very long time to utilize the functionality, but the red tape has been the biggest bottleneck in the process.
Tesla Europe builds momentum with expanding FSD demos and regional launches
Tesla operates Full Self-Driving in the United States, China, Canada, Mexico, Puerto Rico, Australia, New Zealand, and South Korea.

SpaceX Starship V3 gets launch date update from Elon Musk
The first flight of Starship Version 3 and its new Raptor V3 engines could happen as early as March.
Elon Musk has announced that SpaceX’s next Starship launch, Flight 12, is expected in about six weeks. This suggests that the first flight of Starship Version 3 and its new Raptor V3 engines could happen as early as March.
In a post on X, Elon Musk stated that the next Starship launch is in six weeks. He accompanied his announcement with a photo that seemed to have been taken when Starship’s upper stage was just about to separate from the Super Heavy Booster. Musk did not state whether SpaceX will attempt to catch the Super Heavy Booster during the upcoming flight.
The upcoming flight will mark the debut of Starship V3. The upgraded design includes the new Raptor V3 engine, which is expected to have nearly twice the thrust of the original Raptor 1, at a fraction of the cost and with significantly reduced weight. The Starship V3 platform is also expected to be optimized for manufacturability.
The Starship V3 Flight 12 launch timeline comes as SpaceX pursues an aggressive development cadence for the fully reusable launch system. Previous iterations of Starship have racked up a mixed but notable string of test flights, including multiple integrated flight tests in 2025.
Interestingly enough, SpaceX has teased an aggressive timeframe for Starship V3’s first flight. Way back in late November, SpaceX noted on X that it will be aiming to launch Starship V3’s maiden flight in the first quarter of 2026. This was despite setbacks like a structural anomaly on the first V3 booster during ground testing.
“Starship’s twelfth flight test remains targeted for the first quarter of 2026,” the company wrote in its post on X.
