SpaceX CEO Elon Musk says first orbital Starship prototype will be done by June
SpaceX CEO Elon Musk says that the company’s first Starship prototype – a low-fidelity hop test vehicle – has finished assembly in South Texas, paving the way towards a series of experimental vertical take-off or landing (VTOL) hop tests that could begin as early as February or March 2019.
One step beyond the prototype currently rising out of the coastal Texas wetlands, Musk also indicated that the first orbital Starship prototype – essentially the spacecraft’s first full-fidelity test article – could be completed as early as June 2019, a truly extraordinary pace of development for a program as complex and cutting-edge as BFR.

Starhopper rising
Barely six weeks after work began on the massive Starship prototype, SpaceX’s Starhopper appears to have grown to its full ~40m (~130 ft) height in South Texas. Following a preliminary fit test on Tuesday, January 8th, workers made a second attempt on Wednesday and completed the final attachment of Starhopper’s upper and lower halves. Intriguingly, no time was wasted spot-welding the halves together after their successful docking, and an additional sheet of stainless steel has been welded over the seam in the hours since then.

However, what looks like 9m-diameter (~30 ft) steel tank domes are being assembled and welded together at the same SpaceX facility, despite the fact that no domes have been observed being installed inside Starhopper. Musk did seem to indicate that even Starhopper – requiring far less propellant than an orbital Starship – will still feature full 9m (~30 foot) diameter tanks. This could imply that the newly integrated Starhopper has yet to have propellant tank domes installed inside and will need to be taken apart again to allow for that critical final step. If that is not the case, the only possible explanation is that Starhopper’s propellant tanks will actually be less than 9m in diameter and will be lifted up through the vehicle’s aft for installation.
One last increasingly improbable possibility is that a significant portion of the hopper’s upper half will be or already is a pressure vessel capable of holding cryogenic propellant, although the process of actually watching the less than surgical fabrication does not inspire a great deal of confidence in any potential pressure vessel aspirations. In the meantime, we have been given the first look at what the outside of Starhopper will look like once complete. According to SpaceX CEO Elon Musk, hop tests of the imposing vehicle could begin as few as 4-8 weeks from now.

To orbit, and beyond!
Aside from offering the above photo and comparing Starhopper’s prospects to those of Falcon 9’s Grasshopper and F9R hop test articles (i.e. very suborbital and very short-lived), Musk also stated that the first orbital Starship prototype could be completed as early as June 2019, as few as three months after Starhopper’s first hop test. This paints at least a rough picture of the planning going on for BFR’s flight test regime, beginning with a suborbital hop test prototype, moving to a full-fidelity Starship capable of high-speed intra-atmospheric heat shield and aero surface testing, and finally full-up orbital testing with the completion of the first BFR booster (now known as Super Heavy).
Should be done with first orbital prototype around June

Both, but demo Starship is being built now, whereas Super Heavy hardware will start getting built in spring
— Elon Musk (@elonmusk) December 9, 2018
According to Musk, the first Super Heavy booster will begin production and assembly as early as spring 2019, while the CEO stated that he believed the odds of BFR (Starship/Super Heavy) reaching orbit by 2020 were 60% and “growing rapidly” thanks to a recent move from carbon composite tankage to stainless steel. If SpaceX and Musk keep putting their money where their mouths are and rapidly building test articles and prototypes, that orbital debut might actually be less insane than it sounds. We’ll find out soon enough.

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.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.
