SpaceX fits Starship prototype with tank bulkheads as hop test pad progresses
SpaceX workers have begun installing fuel and oxidizer tank bulkheads inside the first BFS/Starship prototype at the same time as the vehicle’s nearby ‘launch’ facility continues to sprout important infrastructure and slowly morph from a giant pile of dirt into something capable of supporting rocket hop tests.
Several observable characteristics of this project still do not immediately make sense but whatever the direction SpaceX is moving in, engineers and technicians are working around the clock to ensure that progress is steady.

Moreso than any other single part, the most confusing aspect of Starhopper has to be the apparent condition of its steel tank domes, distinctly covered with a patina of impurities like rust, dirt, dust, and grime. For a water tower or other miscellaneous storage tank, this would be completely acceptable. For aerospace-grade propellant tanks that will have to safely store dozens or even hundreds of tons of supercool liquid methane and oxygen to feed ultra-high-performance Raptor engines, the purity of ingested propellant and thus the cleanliness of the tanks holding it is going to be of paramount importance.
To use an example that applies to the rockets SpaceX currently flies, Falcon 9’s first and second stages are almost always drained and cleaned before and after their first static fire tests in McGregor, Texas to ensure that no unintended debris is ingested by Merlin turbopumps. This is necessary because Falcon rockets are currently built in an extremely large hangar that simply cannot feasibly be kept to cleanroom conditions, while SpaceX’s garment requirements are less strict than some old-guard aerospace companies, typically letting workers wear normal clothes (albeit with hairnets/beardnets) while working inside Falcon 9 tanks and structures. The improved work conditions and worker comfort comes at the cost of frequent tank cleaning.

While SpaceX clearly has a great deal of experience with nontraditional methods of rocket production, the Hawthorne assembly line might be the cleanest cleanroom on Earth compared to Starhopper’s rusty tank domes and fully-outdoors assembly. Even odder is the apparent fact that SpaceX is actually installing (and maybe even welding) those tank domes without any cleaning at all, indicating that they either look far worse than they actually are, are not a real problem for Raptor or cryogenic propellant tanks, or will be scoured only after installation. Regardless, SpaceX is keeping close followers and those familiar with aerospace on the tips of their toes as Starhopper continues to be worked on.
(Launch) pad progress
Roughly one mile to the east of Starhopper’s assembly roost, SpaceX employees and contractors have been working to complete earthmoving and start outfitting a prospective Starhopper prototype launch pad with a stable concrete base and all the infrastructure needed to support a complex rocket and its propellant, electricity, and heat-resistant surface needs. However, despite recent statements from executives like CEO Elon Musk and COO/President Gwynne Shotwell, the ‘facility’ appears to be many, many months away from anything reminiscent of an actual launch pad like the three SpaceX currently operates in California and Florida.

Instead, it seems that the first BFR-related launch facility will be more of a Spartan, minimalist slab of concrete, a healthy berm, and a handful of propellant tanks and heat exchangers, much like the ‘pad’ that supported Falcon 9’s Grasshopper and F9R hoppers. Over the last few days, the pad construction crew has installed the first of those propellant tanks and heat exchangers and continue to refine the overall layout of the site, still primarily made of compacted dirt. Given the potential simplicity of a Grasshopper-style launch and landing pad, the facility could be anywhere from a few weeks to a few months away from completion.

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.

Tesla finally brings a Robotaxi update that Android users will love
The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android.
Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.
Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.
According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.
🚨 It looks like Tesla is preparing to launch the Robotaxi app for Android users at last!

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:
“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”
This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.
The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.
Tesla is working to increase Android capabilities in its vehicles
Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”
Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.
Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.
