SpaceX’s second Super Heavy booster might land in Mechazilla’s arms
CEO Elon Musk says that SpaceX could attempt to catch a Super Heavy booster out of mid-air with a tower-sized ‘Mechazilla’ robot as early as Starship’s second orbital launch attempt.
Speaking on Twitter just hours after SpaceX installed said Starship launch tower’s first arms, Musk has thankfully answered a question on the minds of many: how many prototype boosters must be expended? In a move that can be only described as unexpected, SpaceX revealed plans to fully expend its first orbital-class Starship and Super Heavy booster pair in May 2021 FCC filings, confirming (or strongly implying) that no true recovery attempts would be made.
Instead, in what could be described as a quasi-orbital debut, SpaceX intends to launch the first two-stage Starship to an altitude of around 200-300 km (TBD). Like many Falcon boosters, Super Heavy will separate a few minutes after liftoff, flip around, and boost back towards the South Texas coast, where it will attempt a soft landing 20 miles offshore in the Gulf of Mexico. Reading between the lines of Musk’s latest info, depending on the results of that ocean landing attempt, SpaceX might attempt to catch the second flightworthy Super Heavy booster on the very next launch.
Heading towards a similar fate, Starship will continue onwards and upwards like a Falcon upper stage. Based on its FCC application, SpaceX seems to have implied that Starship will stop just short of true orbit – traveling slow enough to passively reenter Earth’s atmosphere before completing a full trip around the planet. Of course, it’s possible that SpaceX simply left out plans for an intentional deorbit burn, but it does make sense that the company might try to lock in safeguards for such an ambitious inaugural test flight.
In other words, if Starship were to fail during the ~80 minutes it would spend coasting in space, its launch trajectory design would more or less passively prevent a Russian roulette scenario reminiscent of China’s recent spate of uncontrolled reentries. The feats facing Super Heavy are thankfully a fair bit simpler, though Starship booster recovery does pose its own hurdles.
In an apparent effort to reduce risk, SpaceX intends to fully expend the first flightworthy Super Heavy (potentially Booster 4) and all 29 of its Raptor engines. There will be no attempt at all to land the booster or its one-of-a-kind engines at land or on a sea-based platform – partly because Elon Musk appears to have endeavored to entirely prevent the installation – and, perhaps, the design and assembly – of legs. Instead, in one of the eccentric executive’s less intuitive gambles as of late, SpaceX will entirely dispense of more than half a decade of experience landing 90+ Falcon boosters on legs to attempt to catch Super Heavy boosters out of the air with house-sized arms tacked onto a 145m (~475 ft) tall tower.
No different than a hypothetical landing with legs, Super Heavy will still have to boost back to land, coast, and fire up several Raptor engines for a final landing burn – only on tiny handle-like hardpoints and giant moving arms instead of legs and a concrete pad. If catching boosters eventually proves reliable enough to be a worthwhile reinvention of the wheel, the only apparent benefit of the approach will be a slight reduction in Super Heavy’s dry mass.
According to Musk, though, SpaceX might not have to wait long to find out just how viable a recovery method ‘Mechazilla’ really is and will “hopefully” attempt to catch Super Heavy Booster 5 (B5) after Starship’s second orbital launch attempt. Presumably, that attempt is contingent upon FAA approval and on Booster 4 successfully simulating a smooth, accurate landing in the Gulf, as even a minor issue during a catch attempt could catastrophically damage pad hardware that would take months to repair or replace.
For now, it’s almost impossible to say when Starship S20 and Super Heavy B4 will be ready for their orbital launch debut, as that now lies almost solely in the hands of the FAA. In theory, the FAA could complete environmental reviews and grant SpaceX a launch license as few as two or so months from now. In practice, SpaceX could be forced to sit and wait for at least 6-12 more months. Regardless, SpaceX has already begun assembling and staging sections of Ship 21 and Booster 5, so the company could be ready for an extremely rapid turnaround (and Mechazilla’s first catch attempt) after Starship’s orbital launch debut – whenever that may come.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Tesla, SpaceX, and xAI unveiled TERAFAB, a $25B chip factory targeting one terawatt of AI compute annually.
Elon Musk took the stage over the weekend at the defunct Seaholm Power Plant in Austin, Texas, to officially unveil TERAFAB, a $20-25 billion joint venture between Tesla, SpaceX, and xAI that he described as “the most epic chip building exercise in history by far.” The announcement marks the most ambitious infrastructure bet Musk has made since Gigafactory 1 in Sparks, Nevada, and it fuses three of his companies into a single, vertically integrated AI hardware machine for the first time.
TERAFAB is designed to consolidate every stage of semiconductor production under one roof, including chip design, lithography, fabrication, memory production, advanced packaging, and testing. At full capacity, the facility would scale to roughly 70% of the global output from the current world’s largest semiconductor foundry from Taiwan Semiconductor Manufacturing Company (TSMC).
Elon Musk’s stated goal is one terawatt of computing power annually, split between Tesla’s AI5 inference chips for vehicles and Optimus robots, and D3 chips built specifically for SpaceXAI’s orbital satellite constellation.
Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
The logic behind the merger of these three entities is rooted in a supply chain crisis Musk has been signaling for over a year. At Tesla’s Q4 2025 earnings call, he warned investors that external chip capacity from TSMC, Samsung, and Micron would hit a ceiling within three to four years. “We’re very grateful to our existing supply chain, to Samsung, TSMC, Micron and others,” Musk acknowledged at the Terafab event, “but there’s a maximum rate at which they’re comfortable expanding.” Building in-house was, in his framing, not a strategic option, but a necessity.
The space angle is where the announcement becomes genuinely unprecedented. Musk said 80% of Terafab’s compute output would be directed toward space-based orbital AI satellites, arguing that solar irradiance in space is roughly 5x greater than at Earth’s surface, and that heat rejection in vacuum makes thermal scaling viable. This directly feeds the SpaceXAI vision, which is betting that within two to three years, running AI workloads in orbit will be cheaper than doing so on the ground. The satellites, powered by constant solar energy, would effectively turn low Earth orbit into the world’s largest data center.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Historically, this announcement threads together every major Musk initiative of the past two years: the xAI-SpaceX merger, Tesla’s $2.9 billion solar equipment talks with Chinese suppliers, the 100 GW domestic solar manufacturing push, the Optimus humanoid robot program, and Starship’s development. TERAFAB is the capstone that ties them into a single coherent architecture — chips made on Earth, launched by SpaceX, powered by Tesla solar, run by xAI, and ultimately extended to the Moon.
“I want us to live long enough to see the mass driver on the moon, because that’s going to be incredibly epic,”Musk said during the presentation.

Rolls-Royce makes shocking move on its EV future
When Rolls-Royce unveiled its first all-electric model, the Spectre, in 2022, former CEO Torsten Müller-Ötvös declared the brand would cease production of internal combustion engine vehicles by the end of the decade.
Rolls-Royce made a shocking move on its EV future after planning to go all-electric by the end of the decade. Now, the company is tempering its expectations for electric vehicles, and its CEO is aiming to lean on its legacy of high-powered combustion engines to lead it into the future.
In a significant reversal, Rolls-Royce Motor Cars has scrapped its ambitious plan to become an all-electric manufacturer by 2030. The luxury British marque announced the decision amid sustained customer demand for traditional combustion engines and shifting regulatory landscapes.
When Rolls-Royce unveiled its first all-electric model, the Spectre, in 2022, former CEO Torsten Müller-Ötvös declared the brand would cease production of internal combustion engine vehicles by the end of the decade.
The move aligned with the industry’s broader push toward electrification, promising silent, effortless power befitting the “Rolls-Royce of cars.”
However, new CEO Chris Brownridge, who assumed the role in late 2023, has reversed course. “We can respond to our client demand … we build what is ordered,” Brownridge stated.
The company will continue offering its iconic V12 engines, which remain a cornerstone of its heritage and appeal to discerning buyers who appreciate the distinctive sound and character. He noted the original pledge was “right at the time,” but “the legislation has changed.”
While not abandoning electric vehicles entirely, the Spectre remains in production, with an electric Cullinan option forthcoming; the decision marks the end of a strict all-EV timeline. Relaxed emissions regulations and slowing EV demand, evidenced by a 47 percent drop in Spectre sales to 1,002 units in 2025, forced the reconsideration.
It was a sign that perhaps Rolls-Royce owners were not inclined to believe that the company’s all-EV future was the right move.
Rolls-Royce joins a growing roster of automakers reevaluating aggressive electrification targets.
Fellow luxury brand Bentley has pushed its full electrification from 2030 to 2035, while continuing to offer hybrids and ICE models. Mercedes-Benz walked back its 2030 all-EV goal, now aiming for about 50% electrified sales while keeping combustion engines into the 2030s. Porsche has abandoned its 80% EV sales target by 2030, delaying models and extending hybrids.
Mainstream giants are following suit. Honda canceled its U.S. EV plans, including the 0-Series and Acura RSX, facing a $15.7 billion hit as it doubles down on hybrids. Ford and General Motors have incurred tens of billions in writedowns, canceling models and pivoting to hybrids amid an industry total exceeding $70 billion in charges.
This trend reflects a pragmatic shift driven by infrastructure gaps, consumer preferences, and policy changes. In the ultra-luxury segment, where emotional connection reigns, automakers are prioritizing flexibility over rigid deadlines, ensuring brands like Rolls-Royce evolve without alienating their core clientele.

This optimistic timeline for tape-out—the stage where chip design is finalized before manufacturing—signals Tesla’s push to rapidly advance its silicon capabilities.
The announcement builds on progress with the predecessor AI5. Earlier in January, Musk announced that the AI5 design was “in good shape” and “almost done,” describing it as an “existential” project for the company that demanded his personal attention on weekends.
He characterized AI5 as roughly equivalent to Nvidia’s Hopper class performance in a single system-on-chip (SoC) and Blackwell-level as a dual configuration, but at significantly lower cost and power usage.
Elon Musk is setting high expectations for Tesla AI5 and AI6 chips
Musk highlighted that AI5 “will punch far above its weight” thanks to Tesla’s co-designed AI software and hardware stack, making maximal use of every circuit. While capable of data center training tasks, it is primarily optimized for edge computing in Optimus robots and Robotaxi vehicles.
For AI6, Musk envisions substantial gains. “In the same half reticle and same process node, we think a single AI6 chip has the potential to match a dual SoC AI5,” he explained.
The company is targeting ambitious nine-month development cycles for future chips, allowing rapid iteration to AI7, AI8, and beyond. AI5/AI6 engineering remains Musk’s top time allocation at Tesla, with the CEO calling AI5 “good” and AI6 “great.”
Samsung is expected to manufacture the AI6 chips, following deals worth billions, while AI5 will leverage TSMC and Samsung production. These chips will form the backbone of Tesla’s Full Self-Driving system, enabling safer and more capable autonomy, alongside powering dexterous movements in Optimus bots and efficient inference in expanding data centers.

Musk has also restarted work on the Dojo 3 supercomputer project now that AI5 is progressing. Long-term plans include in-house manufacturing via the Terafab facility.
By accelerating chip development with AI tools, Tesla aims to reduce dependence on third-party GPUs and deliver high-performance, energy-efficient solutions tailored to its ecosystem. Success with AI6 could mark a major milestone in Tesla’s journey toward full autonomy and robotics leadership, though timelines remain subject to manufacturing realities.
