SpaceX rolls Super Heavy booster to orbital launch mount
For the third time in four months, SpaceX has rolled the first potentially flightworthy Super Heavy booster towards Starbase’s orbital launch mount.
Combined with a large crane – fitted with a jig solely used to lift boosters – moving to a spot just beside the booster, it’s clear that SpaceX is preparing to reinstall Super Heavy Booster 4 (B4) on the orbital launch mount. In the context of its unusual history, though, what happens next to the first more or less finished prototype of the largest rocket booster ever built is less clear.
After a shockingly quick assembly over the course of six summer weeks, Super Heavy Booster 4 rolled out of Starbase’s ‘high bay’ facility and headed to the nearby orbital launch complex, where it was installed on a custom ‘mount’ designed to support booster testing and orbital launches. It’s now clear that during that early August photo opportunity and fit test, Booster 4 was nowhere close to finished. Nor, apparently, was it anywhere close to complete one month later when it returned to the orbital pad for the second time after another few weeks of work back at the high bay.


Three months (almost 14 weeks or 100 days) after the Super Heavy prototype’s second trip to the pad, SpaceX has yet to attempt to put the booster through a single proof test. There also appears to be a significant amount of work left to finish installing external ‘aerocovers’ and a heat shield meant to enclose all 29 of its Raptor engines. In the three-year history of Starbase, there isn’t a single prototype of the roughly two-dozen SpaceX has built, tested, and even flown that’s spent even half as long as Super Heavy B4 between apparent structural completion and its first test. Perhaps the fact that Booster 4 is a first-of-its-kind pathfinder explains SpaceX’s uncharacteristic sluggishness or reluctance to actually test the rocket.
In every other instance, SpaceX’s approach to Starship development has been to move incredibly quickly, build a large number of prototypes, and rapidly test those prototypes – often resulting in catastrophic failures. Data is gathered from those failures (SN1, SN3, SN4, SN8, SN9, SN10, SN11, and half a dozen smaller test tanks serve as examples), changes are made, and then the new and improved prototypes that follow repeat the process until SpaceX arrives at a successful design.
Super Heavy B4’s circuitous path has been almost nothing like those of its predecessors. That could also be partly explained by the unavailability of a stand or facilities capable of truly proof testing a Super Heavy, which necessitates a supply of around 3200 tons (7M lb) of liquid nitrogen (LN2; for a cryogenic proof test with full tanks), another 3200 tons of a combination of liquid methane (LCH4) and oxygen (LOx), and the ability to ignite – and survive – as many as 29 to 33 Raptor engines. The suborbital stands SpaceX has used to proof Starships and even Super Heavy Booster 3 don’t even have half the storage capacity required to fully test a booster and the mounts and their surroundings would likely be catastrophically damaged or destroyed by the thrust and blast created by dozens of Raptors.
Still, SpaceX could have theoretically put Booster 4 through a partial cryoproof and maybe fired up as many as nine Raptors at once – not a replacement for full proof testing but still plenty to ensure Super Heavy’s structural integrity and gather invaluable data on clustered Raptor performance. Instead, of course, Super Heavy B4 has sat at Starbase’s former landing zone for more than three months while teams removed engines, reinstalled engines, half-installed a full Raptor heat shield; and installed two of six or seven ‘aerocovers’ needed to protect heat exchangers, racks of pressure vessels, and hydraulic systems installed on the booster’s aft.


This is all to say that from the outside looking in, Booster 4’s path towards testing and flight has been almost entirely different from that of any other Starship prototype. While still quick in comparison with other launch vehicle development programs, relative to other Starship and Super Heavy prototypes, the rate of B4 progress has been far slower – strongly implying that something is seriously wrong with the booster, that SpaceX no longer feels that partial testing is worth the effort, that finishing Booster 4 just hasn’t been a priority for several months, or some combination of the above.
What that ultimately means is that it’s almost impossible to predict what Super Heavy B4’s future holds beyond the clear evidence that SpaceX will soon reinstall to reinstall it on an orbital launch mount that’s much closer to completion than it was the last time B4 was installed. At this point, it’s just as likely that the booster’s third launch mount installation will just be another mechanical fit test, though the hope is that it will kick off full-scale pneumatic and cryogenic proof testing. It could even culminate in the static fire of some or all of its 29 Raptor engines, which have been installed for several months.

Tesla Cybercab almost looks production ready in new photos
Tesla’s AI team recently posted an image of the Cybercab going Animal Style at an In-and-Out drive-through.
Tesla’s AI team recently posted an image of the Cybercab going Animal Style at an In-and-Out drive-through. But while the Cybercab’s passengers were quite funny, the photos themselves suggest that some of the Cybercab’s components may already be production-ready.
Cybercab goes Animal Style
Seemingly as a fun Halloween post, the Tesla AI team shared a photo of a Cybercab, complete with passengers who were in costume, at an In-and-Out drive through. Based on the photos that were shared on X, it appeared that the Cybrcab was being accompanied by a Tesla Model Y Premium. The Tesla AI team shared a lighthearted caption to the image, writing “Animal Style,” a reference to a popular secret menu item for the fast food chain.
In a way, the Tesla AI team’s Halloween post was a lighthearted reference to the popularity of In-and-Out among Tesla owners. This is partly because of the Tesla Supercharger network, which has numerous locations that are close to In-and-Out sites. Elon Musk has also jokingly confirmed in the past that driving prototype Teslas through an In-and-Out is a tradition and a fun milestone marker.
Apparent production-ready Cybercab sections
While the Tesla AI team’s photos provided some lighthearted fun to the EV community, some industry watchers pointed out that the Cybercab in the photos looked production ready, or at least some parts of it seem to be. This is especially noticeable in the Cybercab’s front end, which looks very refined and well-built.
The front end of the Cybercab on the In-and-Out photo even had a license plate mount, and previous sightings revealed that the door of the vehicle had been updated since it was unveiled last year.
With this in mind, speculations are abounding that the Cybercab might indeed be ready for initial production soon. The installation of production equipment in Giga Texas has been ongoing for several months now, and tests of the Cybercab in both the Giga Texas complex and on public roads have also ramped.

Michael Dell points out practical advantage of Elon Musk’s proposed pay package
As pointed out by the Dell Technologies CEO, Musk will only be rewarded if he delivers extraordinary value to shareholders
Michael Dell has weighed in on Elon Musk’s controversial 2025 CEO Performance Award, offering a grounded perspective amidst the noise surrounding the pay package today.
As pointed out by the Dell Technologies CEO, Musk will only be rewarded if he delivers extraordinary value to shareholders. Musk would quite literally receive no compensation if he fails to achieve his targets.
Dell emphasizes results over rhetoric
Dell shared his thoughts about Musk’s 2025 CEO Performance Award in a post on X.“Vote FOR Elon Musk. The award is only achieved IF he hits exceptionally ambitious market-cap and operational milestones—if he falls short, he gets nothing,” Dell wrote in his post.
“If he succeeds, shareholders will win big through unprecedented value creation, and he will earn added voting rights to continue driving Tesla’s long-term vision.”
Musk replied with a short “Thanks Michael,” acknowledging Dell’s support. Dell’s framing cuts through the debate surrounding Musk’s compensation, as he simply focused on the incentive structure’s risk-reward balance.
Musk’s ambitious pay package
Elon Musk’s 2025 CEO Performance Award requires Tesla’s market capitalization to rise from roughly $1.1 trillion today to $8.5 trillion within a decade. This would make Tesla more valuable than any company in history.
Apart from this, Tesla’s operating profit must also grow from $17 billion to $400 billion annually. Musk must also lead the company to several product-related milestones, such as 20 million cumulative vehicle deliveries, 10 million Full Self-Driving subscriptions, 1 million Tesla Bots, and 1 million operating Robotaxis.
So far, proxy advisors Glass Lewis and ISS have urged shareholders to vote against the plan. Some prominent investors, including ARK Invest CEO Cathie Wood, however, have voiced strong support for the plan. Wood called Musk “the most productive human being on earth,” arguing that his vision and ability to attract talent are central to Tesla’s success.

Starlink V3 satellites could enable SpaceX’s orbital computing plans: Musk
Musk’s remarks come as companies explore how orbital infrastructure could solve the Earth-bound energy and cooling challenges that come with hyperscale AI computing.
As artificial intelligence fuels surging demand for computing power, Elon Musk has hinted that SpaceX may use its Starlink V3 satellites to develop space-based data centers.
Musk’s remarks come as companies explore how orbital infrastructure could solve the Earth-bound energy and cooling challenges that come with hyperscale AI computing.
SpaceX could lead the race to orbit-based computing
After Ars Technica published a report on autonomous space construction, Musk replied on X: “Simply scaling up Starlink V3 satellites, which have high speed laser links would work. SpaceX will be doing this.”
SpaceX’s Starlink V3 platform is capable of up to 1 terabit per second (Tbps) throughput, so it could potentially form the foundation for orbital computing clusters powered by solar energy.
Proponents have noted that such data centers could eliminate the massive land, water, and power footprints of traditional facilities on Earth. Critics, however, have question the economics and complexity of maintaining large-scale data systems in orbit.
Elon Musk, for his part, recently reiterated on X that this particular idea is a very big deal.
SpaceX’s track record is substantial
Despite the reservations for such a radical idea, SpaceX’s track record is pretty much bulletproof at this point. The company’s Starlink network, once deemed as unrealistic by critics, now delivers broadband to millions worldwide while turning a profit. Its Falcon 9 rockets, which are capable of landing on land or on a drone in the middle of the ocean, are also among the world’s most reliable.
With this track record in mind, it would seem that Elon Musk’s idea of using Starlink satellites as the building blocks for a space-based data center might not be too farfetched at all.
Interest in space-based data storage and processing has intensified in recent months, Ars noted. Former Google CEO Eric Schmidt reportedly acquired Relativity Space with an eye on orbital data infrastructure, while Jeff Bezos recently predicted gigawatt-scale data centers will operate in space within two decades.
