SpaceX could begin testing its Mars rocket in Texas by late 2018, early 2019
On the heels of a successful wet dress rehearsal for Falcon Heavy, SpaceX’s President and COO Gwynne Shotwell spoke briefly about SpaceX for an aerospace conference located at Texas’ Academy of Medicine, Engineering & Science. Ars Technica’s senior spaceflight editor Eric Berger was in attendance and provided a rough outline of live tweets during the first group of presentations.
While the phrasing cannot provide absolute confirmation, Berger summarized a statement by Shotwell suggesting that SpaceX’s Boca Chica, Texas launch site, currently in the early stages of construction, could be ready to host “vehicle tests” as soon as late 2018, early 2019. At this point in time, based on comments from Shotwell and CEO Elon Musk, it can be reasonably assumed that SpaceX’s Texas launch facilities will be dedicated mainly to the company’s interplanetary colonization efforts, and will probably be tailored to support the testing and eventual launches of BFR/BFS.
Some news from Shotwell: Brownsville launch site ready for vehicle tests in late 2018, early 2019. Move to launch site after that.

After nine months of earnest construction and rehabilitation, SpaceX’s LC-40 pad was recently reactivated and has since supported two launches without any major hitches. At the same time, LC-39A in flux in order to support launches of SpaceX’s new Falcon Heavy rocket, the size of which required some concomitant upgrades to multiple ground systems. With both of those major tasks now effectively complete, SpaceX’s pad construction team is free to either refocus their efforts towards Boca Chica. Over the past several months, Boca Chica has seen a gradual but consistent level of development, mainly by way of unaffiliated SpaceX contractors. These changes have been dutifully tracked over the last several years on NASASpaceflight.com forums by a handful of friendly local residents interested in the changes coming to Boca Chica and Brownsville, Texas, a nearby town.

Most significantly, the last several months have seen three major developments. First and most prominently, a permanent facility called STARGATE externally appears complete and its two large radio communication dishes have been installed nearby. The STARGATE facility is a public-private partnership between the University of Texas at Brownsville (now part of University of Texas Rio Grande Valley) and SpaceX, with the academic components focusing on research that SpaceX undoubtedly has interest in: improved orbital spacecraft tracking and communications. Operationally, SpaceX will use the facilities to communicate with and operate its Crew Dragon spacecraft during launches, set to begin with an uncrewed demonstration mission as early as August 2018.
Second, an absolutely massive trolley crane appeared on SpaceX’s land and was eventually housed in an apparently purpose-built shed. The crane dwarfs anything currently used at SpaceX’s launch facilities and is almost certainly a custom-ordered piece of equipment, and thus would be both expensive and explicitly purposeful. What that purpose might be is currently unknown, but it is entirely plausible that the crane is intended to support initial testing (or even limited manufacturing) of SpaceX’s first BFS prototype rockets. This speculation has now been strengthened by Shotwell’s January 11 2018 comment on potential “vehicle tests” occurring at the site within a year or so, and also meshes with a presentation she gave in October 2017 at MIT. It also fits with Elon Musk’s 2017 IAC comments that BFR construction tooling and facilities were respectively already ordered and under construction.

Third and last, the aforementioned SpaceX-following locals observed the early stages of a solar power install beginning on some of SpaceX’s Boca Chica land in late 2017, and also noted that at least some of its contractors were part of Tesla Solar. Plans and permits for solar power were acknowledged as far back as 2014, although at that point the contractor was Solar City (now a part of Tesla). A handful of months later, NASASpaceflight user and all-around awesome guy Nomadd has installed a webcam on a tall pole with a wonderful view of both the solar installation (now nearly completed) and STARGATE. The acre of solar panels can be expected to produce as much as half a megawatt (MW) at peak sun, likely more than enough to offset a considerable amount of the facilities’ electricity usage even after it begins to be see serious use.

Originally announced as an additional Falcon launch facility in 2014, Boca Chica has remained relatively dormant over the last three years, and it is truly exciting to see activity ramping up. There are admittedly significant barriers that will prevent SpaceX from effortlessly repurposing its Boca Chica pad for BFR, a much larger rocket. If SpaceX intends to do that, they will almost certainly need to pass a significantly updated FAA environmental impact review and account for any remediations that might be required. Still, that is a small ask for for Brownsville’s local government and Texas as a whole, both of which have clearly enjoyed and begun to benefit from SpaceX’s presence in the otherwise unknown area. SpaceX is unlikely to give up on Boca Chica in the near term, so long as Ms. Shotwell maintains her belief that it is effectively the perfect location for BFR launches.
Overall, Shotwell’s comments over the last several months and today in particular are increasingly encouraging, and things are likely to only speed up as 2018 progresses, allowing SpaceX to focus more and more of its expertise on BFR, BFS, and its South Texas testing and launch facilities.
Full disclosure: As Shotwell did not specify which vehicle or vehicles could be expected to begin testing in 2018/2019, it is possible that Falcon 9, not BFR, was the statement’s target. This article should be taken with a grain of salt, as it is educated speculation based upon public information from SpaceX executives and Texas contractors. Teslarati reached out to SpaceX for additional information, but the company was unable to comment further on Shotwell’s presentation at the moment.

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.
