SpaceX sends Starship prototype to launch pad after engine installation
After several weeks of work back at SpaceX’s Starbase rocket factory, the company has transported a new and improved Starship prototype to nearby test and launch facilities, where it joined a similarly upgraded Super Heavy booster.
That Starship prototype – Ship 24 or S24 – is closely following in the footsteps of Super Heavy Booster 7 (B7), which kicked off a similar phase of preflight testing about two weeks ago. The purposes of their latest trips from the factory to the launch pad are also largely the same and could potentially open the door for Starship’s inaugural orbital launch attempt sometime later this year if the process goes smoothly. Both protypes have a ways to go, however.
Booster 7 and Ship 24 got off to fairly rocky starts when they began a less risky phase of proof testing in May and June. Apparently caused by improper sequencing or a small design flaw, a large steel tube meant to carry liquid methane fuel through Booster 7’s liquid oxygen tank and double as a storage vessel for landing propellant violently imploded when a vacuum formed inside it. It took SpaceX several weeks to repair the damage but, defying the odds, the tube was eventually repaired and Booster 7 completed another two proof tests soon after.
A few weeks later, during one of Ship 24’s first tests, a much smaller internal pipe – likely carrying high-pressure gas – also failed, damaging heat shield tiles and other adjacent plumbing. S24’s troubles were less dramatic and only took a few days to fix, but both were still new failure modes for the Starship program and served as a reminder that Starship hardware remains relatively immature and that SpaceX is still learning. Nonetheless, they also demonstrated SpaceX’s ability to respond quickly to new problems, as both B7 and S24 sailed through additional testing without apparent issue after quick repairs.
After completing cryogenic proof and thrust simulation testing, B7 and S24 returned to SpaceX’s factory facilities for Raptor installation and finishing touches. SpaceX took about six weeks to install 33 Raptor engines and associated heat shielding on Booster 7, while installing six Raptors and wrapping up a few other aspects of Ship 24 took about four weeks.
Aside from the installation of most of the Starship’s missing heat shield tiles, Ship 24’s preparations did include one particularly unique step involving its payload bay prototype. SpaceX’s first stab at a Starship payload bay has been likened to a giant Pez dispenser, which is not entirely inaccurate. Exclusive to Starlink, satellites will be stored on a rectangular rack that’s assumed to operate like an elevator. As an unknown mechanism pushes two satellites at a time through Starship’s slot-like bay door, the stack of satellites will feed downwards like bullets in a magazine until the full set is fully deployed.
In late June, SpaceX attached a giant white box to a crane and positioned the box to interface with Ship 24’s bay door, where it hung for the better part of a day. The test confirmed speculation that the box was meant to solve perhaps the most obvious problem SpaceX’s unique payload bay design posed: payload installation. SpaceX’s solution appears to involve using the deployment mechanism in reverse, with the white box conveying Starlink Gen2 satellites through the ‘slot’ and the dispenser grabbing and lifting each pair up into the bay.
It’s possible that Ship 24 will have a handful of Starlink V2/Gen2 satellites loaded into its bay if it passes its next tests. Before being cleared for flight, Ship 24 will need to complete at least one nominal wet dress rehearsal (simulating every aspect of a launch short of engine ignition) and one six-engine static fire, though several tests are far more likely. Starship S24’s test campaign will benefit significantly from Starship S20, which survived extensive testing (and multiple six-Raptor static fires) in 2021. In comparison, Super Heavy B7’s similar wet dress rehearsal and static fire test campaign will be almost entirely new to SpaceX, save for a single three-engine static fire completed by an outdated booster prototype last year.
SpaceX could attempt to static fire Booster 7 for the first time as early as Wednesday, July 6th. It’s unclear if the company will attempt to kick off Ship 24’s next round of testing in the gaps between Super Heavy B7’s static fire testing. While unlikely, SpaceX is technically capable of testing Ship 24 and Booster 7 simultaneously.

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.
