SpaceX’s Starhopper cleared by FAA for second and final flight test as locals urged to exit homes
After a full two weeks spent waiting for an FAA permit, SpaceX CEO Elon Musk and local South Texas authorities appear to be preparing Starhopper for a second major flight test as early as Monday, August 26th.
Assuming the FAA comes through with a permit, Starhopper is scheduled to lift off no earlier than 5pm EDT (21:00 UTC) on August 26th for a flight test expected to smash the low-fidelity Starship prototype’s previously altitude record of ~20m (65 ft). Confirming initial reports from NASASpaceflight.com, Musk also stated that Starhopper’s second flight will be its last, after which the steel rocket test-bed will be converted for stationary use at SpaceX’s South Texas facilities.
Prior to Musk tweeting that Starhopper may be nearing approval for its next flight, the SpaceX CEO revealed that delays were centered around the FAA’s apparent unwillingness to permit the vehicle’s next flight. Musk specifically stated that the FAA wanted more “hazard analysis”, meaning that the US aviation administration had concerns that Starhopper could pose a serious threat to local residents in a tiny housing development known as Boca Chica Village.
Technically speaking, Boca Chica Village is just 1.5 miles (2.4 km) away from SpaceX’s Starhopper launch facilities, where the vehicle is expected to reach a maximum altitude of no more than 200m (650 ft) as early as August 26th. FAA regulations tend to be prescriptive and extremely rigid, understandable given the breadth of US aviation-related activities the agency is tasked with regulating. However, a basic back-of-the-envelope analysis of Starhopper’s 200m hop suggests that the risk to local residents – even those as few as 1.5 miles away from the test – is minuscule.
Based on Starhopper’s inaugural flight, its lone Raptor engine – producing up to 200 tons (450,000 lbf) of thrust – is not exactly capable of rapidly moving the Starship prototype. For all accounts and purposes, Starhopper is a spectacularly heavy hunk of steel with the aerodynamics of a cylindrical brick – capable of flight solely through the brute-force application of a literal rocket engine. To make it even half of the distance from its launch site to the Village, Starhopper would have to remain in controlled flight while radically deviating from its planned trajectory, all while its flight termination system (FTS) – explosives meant to destroy the vehicle in a worst-case scenario – completely fails to activate.
As evidence of the apparent lack of perceived risk to local residents, Cameron County, Texas officials distributed flyers to Village residents advising – but not requiring – those choosing to remain at their homes during the test to go outside during Starhopper’s next flight. This is recommended to avoid flying glass in the event that the vehicle explodes, potentially shattering windows with the shockwave that could result, but clearly demonstrates the fact that county officials believe there is a near-zero chance of Starhopper actually impacting anywhere near the houses.
Ultimately, Starhopper’s limited flight tests clearly pose little to no actual risk to residents, but this chapter does raise a far more significant question: what happens once Starship Mk1 is ready and the flight tests SpaceX is pursuing involve distances and heights on the order of several, tens, or hundreds of kilometers? For now, answers will have to wait til a later date.
A Hop and a skip into retirement
Aside from the delays and apparent lack of consensus on the safety of Starhopper’s minor hop tests, Musk confirmed that the prototype’s second test flight ever will likely be its last, providing some interesting insight into SpaceX’s next steps. Most notably, the fact that SpaceX is willing and ready to fully retire Starhopper after such a limited test series serves as a fairly confident statement that orbital-class Starship Mk1 (Texas) and Mk2 (Florida) prototypes are extremely close to flight-readiness.
Roughly a month ago, Musk tweeted that those Starship prototypes could be ready for their first flights as early as mid-September to mid-October, “2 to 3 months” from mid-July. In additional comments made on August 20th, Musk stated that his planned Starship presentation would be delayed in light of Starhopper’s own delays, and is now instead expected to occur around a major Starship Mk1 integration milestone in “mid September”.
As previously discussed on Teslarati, Starhopper’s brief service life is entirely unsurprising, delayed by issues with Raptor engines to the point that SpaceX’s far more valuable Starship prototypes – having made relentless progress – are already nearing completion. Once those Starships are ready for almost any kind of integrated testing, Starhopper will be made entirely and immediately redundant.
“According to Musk, either or both of those orbital-class prototypes could be ready for their inaugural flight tests as early as mid-September, perhaps just 1-2 months from now. Given that Starships Mk1 and Mk2 are significantly higher fidelity than Starhopper, the ungainly testbed will likely become redundant the moment that its successors are ready for flight. In other words, Starhopper is fast approaching the end of its useful life, and SpaceX’s fight for a 200m hop-test permit could ultimately be a waste of time, effort, and money if said permit doesn’t also cover Starship Mk1.”

On another positive note, CEO Elon Musk says that Starhopper won’t be ‘retired’ to the scrapyard and will instead be lightly modified to serve as an in-situ test stand for Raptor engines, a useful addition once SpaceX South Texas moves on to multi-engine Starship and Super Heavy testing.
With any luck, SpaceX will attempt to livestream Starhopper’s second attempted flight. Stay tuned for updates on the 5pm EDT, August 26th test.

Elon Musk teases crazy outlook for xAI against its competitors
Musk’s response was vintage hyperbole, designed to rally supporters and dismiss doubters, something his responses on social media often do.
Elon Musk has never been one to shy away from crazy timelines, massive expectations, and outrageous outlooks. However, his recent plans for xAI and where he believes it will end up compared to its competitors are sure to stimulate conversation.
In a bold and characteristic response on X, Elon Musk fired back at a recent analysis that positioned his AI venture, xAI, as lagging behind industry frontrunners.
The post, from March 14, came as a direct reply to forecaster Peter Wildeford’s assessment, which drew from benchmarks and reporting to rank AI developers.
xAI will catch up this year and then exceed them all by such a long distance in 3 years that you will need the James Webb telescope to see who is in second place
— Elon Musk (@elonmusk) March 14, 2026
Wildeford placed Anthropic, Google, and OpenAI in a virtual tie at the top, with xAI and Meta trailing by about seven months. Chinese players like Moonshot, Deepseek, zAI, and Alibaba were estimated to be nine months behind, while France’s Mistral lagged by about a year and a half.
Musk’s response was vintage hyperbole, designed to rally supporters and dismiss doubters, something his responses on social media often do.
He claimed xAI would “catch up this year,” meaning by the end of 2026, erasing that seven-month deficit against the leaders. But he didn’t stop there.
Musk escalated his vision to 2029, predicting xAI would “exceed them all by such a long distance” that observers would need the James Webb Space Telescope, NASA’s orbiting observatory stationed about 930,000 miles from Earth, to spot whoever lands in second place. This analogy underscores Musk’s confidence in xAI’s trajectory, implying an astronomical lead that could redefine the AI landscape.
Breaking down these claims reveals Musk’s strategic optimism. First, the short-term catch-up: xAI, launched in 2023, has already released models like Grok, but recent benchmarks, including those for Grok 4.2, have shown it falling short in capabilities compared to rivals.
Anthropic’s Claude series, Google’s Gemini, and OpenAI’s GPT models dominate in areas like reasoning, coding, and multimodal tasks. Musk’s assertion suggests aggressive scaling in compute, talent, or architecture, perhaps leveraging xAI’s ties to Tesla’s Dojo supercomputers or Musk’s vast resources, to close the gap swiftly.
The longer-term dominance by 2029 paints an even more audacious picture. Musk envisions xAI not just parity but supremacy, outpacing competitors in innovation speed and model sophistication.
This could involve breakthroughs in energy-efficient training, real-world integration, like Tesla’s robotics, or ethical AI alignment, aligning with Musk’s stated goal of “understanding the universe.”
Critics, however, point to parallels with Tesla’s Full Self-Driving delays; one reply highlighted Musk’s 2023 promise of FSD readiness. Musk has made this promise for many years, and although the system has been strong and improving, it is still a ways off from the completely autonomous operation that was expected by now.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
Musk’s comment highlights the intensifying U.S.-centric AI race, with xAI challenging the “three-way” dominance noted by Wharton professor Ethan Mollick, whom Wildeford quoted. As geopolitical tensions rise—evident in the Chinese firms’ lag—Musk’s tease could spur investment and talent wars.
Yet, it also invites scrutiny: Will xAI deliver, or is this another telescope-needed mirage? In an industry where timelines slip but stakes soar, Musk’s words keep the spotlight on xAI’s ambitious path forward.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Tesla set to launch “Terafab Project: A vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla is making one of the boldest bets in its history. On March 14, Elon Musk posted on X that the “Terafab Project launches in 7 days,” pointing to March 21, 2026 as the start date for what he has described as a vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla first confirmed Terafab on its January 28, 2026 earnings call, where Musk told investors the company needs to build a chip fabrication facility to avoid a supply constraint projected to materialize within three to four years. But the seeds were planted even earlier. At Tesla’s annual general meeting last year, Musk warned that even in the best-case scenario for chip production from their suppliers, it still wouldn’t be enough, and declared that building a “gigantic chip fab” simply had to be done.
While there has been no official announcement on where Tesla plans to break ground on the massive Terafab, all signs point to the North Campus of Giga Texas in Austin.
Months of speculation has surrounded Tesla’s North Campus expansion at Giga Texas, where drone footage captured by observer Joe Tegtmeyer revealed massive construction site preparation just north of the existing factory on a scale that rivals the original Giga Texas footprint itself.
Samsung’s Tesla AI5/AI6 chip factory to start key equipment tests in March: report
The project is projected to produce 100–200 billion AI and memory chips annually, targeting 100,000 wafer starts per month, at an estimated cost of $20 billion. Tesla is targeting 2-nanometre process technology and anticipated to be the most advanced node currently in commercial production. Dubbed the Tesla AI5 chip, the chip will pack 40x–50x more compute performance and 9x more memory than AI4, and will be among the first products Terafab factory is set to produce. This highly optimized, and massively powerful inference chip is designed to make full self-driving (FSD) and Tesla’s Optimus robots faster, safer, and with full autonomy.

This is where Terafab becomes a genuine game-changer. If Tesla successfully builds a 2nm chip fab at scale, it becomes one of only a handful of entities that’s capable of producing AI silicon in-house, with competitive implications that extend far beyond Tesla’s own vehicles, and potentially positioning Tesla as a chip supplier or licensor to other industries.

The next-gen Tesla AI chips will power advancements in Full Self-Driving software, the Cybercab Robotaxi program, and the Optimus humanoid robot line. Musk’s projections for Optimus require chip volumes that no existing external supplier can commit to on Tesla’s timeline.Competitors like Waymo and GM’s Cruise remain dependent on third-party silicon, leaving them exposed to the same supply chain vulnerabilities Tesla is now working to eliminate entirely.
The Terafab launch this week may not mean a factory opens its doors overnight, but it signals Tesla is serious about owning the entire AI stack, from software to silicon.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…
— Elon Musk (@elonmusk) March 11, 2026
Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.
— Elon Musk (@elonmusk) March 12, 2026
Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.
