SpaceX CEO Elon Musk teases Mars breakthroughs as Starship design radically changes
During an interview with Axios, SpaceX CEO Elon Musk noted that he was “[really fired up about] a number of breakthroughs [SpaceX had recently made]” while being asked about his thoughts on the likelihood of him personally going to Mars (“70%”).
The minute-long teaser did not go much deeper but it certainly raises a number of questions (and hints at explanations) for a rapid-fire series of contradictory developments and changes to SpaceX’s BFR – since renamed to “Starship” and “Super Heavy” – per a series of tweets from Musk over the last two weeks.
In a typical Muskian fashion, when Axios interviewers asked, “What is the likelihood that you personally will go to Mars?”, the CEO responded with an exact percentage – 70% – without skipping a beat. Musk also fervently and rather eloquently refuted the popular and harebrained idea that any SpaceX-enabled Mars colony would simply become “an escape hatch for the rich”. If the rich wanted Mars or lunar bases as “escape hatches”, there are dozens of multibillionaires that could singlehandedly fund Musk’s estimated $2-10B price tag for the completion of the entire BFR development program while still retaining 50-90% of their net worth.
Musk’s retort is worth reading in full.
Mike Allen: “[Mars] could be an escape hatch for rich people.”
Elon Musk: “No! Your probability of dying on Mars is much higher than earth. Really the ad for going to Mars would be like Shackleton’s ad for going to the Antarctic. It’s gonna be hard. There’s a good chance of death, going in a little can through deep space. You might land successfully. Once you land successfully, you’ll be working nonstop to build the base. So, you know, not much time for leisure, and once you get there, even after doing all this, it’s a very harsh environment, so there’s a good chance you die there. We think you can come back but we’re not sure. Now, does that sound like an escape hatch for rich people?”
Back to BFR
While thoroughly entertaining, the most interesting aspect of this one-minute teaser was the approximate two seconds where Musk suggested that SpaceX had recently made several major breakthroughs in the context of BFR and Mars. What exactly those breakthroughs could be is entirely unclear, but the fact that Musk seemed positive about the recent developments and spoke of “breakthroughs” at all feels like an encouraging sign that the last two weeks of Musk’s chaotic announcements, updates, and abrupt cancellations are less indicative of program instability than they initially seemed to be.
Most notably, Musk appeared to announce and then completely cancel a sort of mini-spaceship that SpaceX was to base off of Falcon 9’s upper stage as a BFR spaceship technology demonstrator in less than two weeks. If realized, that mini-BFS would have reentered Earth’s atmosphere at orbital velocities to flight-test hypersonic fins and a new “ultra light” heat shield that will be (or would have been) critical for the overall success of BFS/Starship.
Contour remains approx same, but fundamental materials change to airframe, tanks & heatshield

Ironically, in the middle of writing this article, Musk tweeted specifically about “fundamental” changes to the spaceship, leaving little more than the general appearance and propulsion systems unchanged. In essence, the design of BFS/Starship is now almost unrecognizable when compared with past iterations, at least from a perspective of the ship’s most critical systems.If Starship will not be built out of composites, then it’s possible that the multiple years SpaceX engineers and technicians have spent trying to develop large carbon composite propellant tanks (2016-present) and the time, energy, and capital put into those efforts will be almost entirely for naught if BFR pivots away from composite tanks.

By all appearances, dozens of employees have spent the last year accepting delivery of $10-50M worth of custom-built composite tooling, setting it up, and building giant composite tank domes and segments. If composite tanks are no longer planned for the booster or spaceship, all that work may have been for nothing. Needless to say, we could certainly do for Musk’s proposed Reddit AMA – if not an entirely new BFR update event – to shed some light on the machinations behind these earthshaking programmatic changes.

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.

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.
