SpaceX’s next Starship starts to take shape as Elon Musk talks next steps
Less than a day after SpaceX successfully hopped a full-scale Starship prototype for the first time, the company has begun stacking the next rocket and Elon Musk is talking next steps.
Almost immediately after Starship SN5 took to the sky on a 150m (500 ft) hop debut, SpaceX CEO Elon Musk was talking about the company’s next near-term goals for the next-generation launch vehicle’s test program. To an extent, he had already offered a rough overview through various interviews and tweets over the last year or so. Aside from continuing to gradually refine Starship and Super Heavy designs and the processes used to manufacture and test those rockets, a few major proofs of concept stand between SpaceX and total confidence in the current architecture.
As far as basic rocketry goes, SpaceX’s 150m Starship hop has functionally proven that the company’s exotic, rule-of-thumb-breaking approach to Starship production and assembly can be feasibly refined into something capable of producing extraordinarily cheap orbital-class rockets. While a massive achievement, it doesn’t guarantee that the rockets produced will be reusable – let alone rapidly and easily reusable.
As of now, it can be safely stated that SpaceX has solved all major challenges involved in routinely and reliably landing and reusing orbital-class rocket boosters (first stages). It’s hard and surprises are always a possibility, but the landing records of Falcon 9 and Falcon Heavy boosters speak for themselves. For the colossal booster Starship needs to reach orbit, the Falcon family’s success means that Super Heavy recovery and reuse is more a question of “when” than “if”.
Starship, on the other hand, is going to offer many different challenges – some unprecedented for SpaceX and others unprecedented in the entire history of spaceflight. For Starship to be able to support a level of reuse compatible with what the Super Heavy booster is likely to achieve, SpaceX will have to create the biggest and most effortlessly reusable orbital-class spacecraft ever built.
Even heavier than NASA’s Space Shuttle orbiter, Starship will also rely almost entirely on the unproven technology of on-orbit cryogenic propellant transfer to reach beyond low Earth orbit (LEO). To survive orbital-velocity reentries while still being rapidly and cheaply reusable, Starship will further have to push the envelope of heat shield technologies. Last but certainly not least, in its current iteration, Starship relies on a truly unprecedented style of recovery to efficiently land back on Earth.
It’s this last bit where CEO Elon Musk’s recent comments and recent activity at SpaceX’s Starship factory come in. According to Musk, SpaceX intends to perform at least several more smaller hops (a la SN5) “to smooth out [the] launch process.” It’s unclear which prototype(s) will be involved in that series of hops but after SpaceX is satisfied with the state of launch operations, the plan is to “go high altitude with body flaps.” Based on past comments, it’s safe to assume that Musk is referring to a plan to launch a Starship to 20 km (~12 mi).
After reaching 20 km, Starship would orient itself belly down – a bit like a skydiver – and quite literally fall its way to ~1 km altitude before attempting an aggressive Raptor-powered pitch-over maneuver and last-second landing. By using Earth’s atmosphere much like a skydiver trying to slow down, Starship will theoretically be able to dramatically reduce the amount of propellant it needs to land.
That high-altitude launch and landing demonstration will also be the first time a Starship truly needs aerodynamic control surfaces (i.e. “body flaps”) to safely complete a flight test. According to NASASpaceflight.com info, Starship SN8 – also the first full-scale prototype to be built out of a different steel alloy – will be the first ship to receive functional flaps and a nosecone. If initial tests go according to plan, SN8 will also be the first ship to attempt a skydiver-style landing as described above. As far as full-scale aerodynamics goes, such a landing is loosely understood at best. For an orbital-class spacecraft, it’s even more of a wildcard.
Regardless, just hours after Starship SN5’s successful hop debut, SpaceX began stacking the first of several already finished Starship SN8 sections. Based on the assembly of past prototypes, the ship’s tank section could reach its full height just a few weeks from now, while subsequent nosecone and flap installations are uncharted territory.

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.

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.
