SpaceX Falcon 9 Block 5 rocket’s drone ship return captured in stunning detail [gallery]
Teslarati photographer Pauline Acalin has captured SpaceX’s first West Coast Falcon 9 Block 5 booster recovery in the best detail yet seen of the rocket upgrade, well-worn after its first successful launch of Iridium NEXT-7, July 25.
Iridium-7 marked a number of important debuts for SpaceX: Falcon 9 Block 5 (Booster 1048, in this case) completed its first West Coast launch from SpaceX’s Vandenberg pad, drone ship Just Read The Instructions’ (JRTI) first rocket recovery attempt and success in nearly ten months, and recovery vessel Mr Steven’s first (albeit unsuccessful) attempt at catching a Falcon fairing with a dramatically enlarged net and arms.

Although inclement wind conditions foiled Mr Steven’s fairing catch effort and put pressure on Falcon 9 B1048’s journey to JRTI, Iridium-7 was flawlessly placed in orbit and Falcon 9 managed a slightly off-center but still thoroughly successful landing on the drone ship off the coast of California. With that launch and land debut on the West Coast and a second successful East Coast launch of a Block 5 rocket to the East just a few days prior, SpaceX has effectively demonstrated the basic functionality and reliability of the upgrade’s many far-reaching changes to the underlying Falcon 9 architecture.

Just Read The Instructions recovers a rocket
After nearly ten months largely spent berthed at SpaceX’s original Port of San Pedro dock space, drone ship JRTI has at long last returned to sea and successfully recovered a Falcon 9 booster, this time marking the West Coast launch and landing debut of the Block 5 rocket. Photos of the drone ship and rocket’s return to port were some of the best ever seen, thanks largely to the port’s layout and narrow mouth, which allowed Teslarati photographer Pauline Acalin to put giant telephoto lenses and a unique top-down perspective to good use.
Iridium NEXT-7 thankfully brought an end to the understandable but still-painful practice of intentionally expending twice-flown Falcon 9 boosters in the ocean after launch. Thanks to Iridium-7’s new Block 5 booster, B1048, expending the rocket was out of the question, as it likely will be for most Block 5 launches in the future. A combination of several expendable missions and an unfortunate duo of recovery anomalies (a small fire after Koreasat 5A and the Falcon Heavy center core landing failure) led to JRTI sitting on the sidelines since October 2017, as a considerable subset of its critical thruster hardware had to be stripped in order to keep East Coast sister ship Of Course I Still Love You (OCISLY) operational for a handful of attempts in 2018.

Many of the months JRTI spent at berth were thus without the pod thrusters the drone ship needs to keep itself at the proper landing point once at sea. Still, JRTI departed the port with a full complement of four blue thrusters on the evening of July 22 and had a highly successful return-to-action. Sadly, it’s unclear how much SpaceX will need the vessel within just a month or two from today – after the final Iridium launch (NEXT-8) in November or December, perhaps all of SpaceX’s future Vandenberg launches will be lofting lightweight payloads that should allow the company to rely almost entirely on its brand-new rocket landing zone – conveniently colocated barely 1000 feet from the pad – for CA rocket recoveries.

Falcon 9 Block 5 booster (B1048) arrived at Port of Los Angeles on July 27 after landing at sea aboard drone ship JRTI. Photos captured by Pauline arguably show the best details yet seen of the rocket upgrade, ranging from titanium grid fins to extraordinary shots of its sooty-but-still-sorta-shiny Merlin 1D engines.

Myriad others provide an amazing sense of place with SpaceX technicians conducting thorough post-landing checkouts, carefully documenting the booster’s condition, and generally wrenching on a massive, orbital-class rocket that completed a suborbital jaunt to space just days prior.
Of particular note are detailed views of the silky black “highly flame-resistant felt” now covering Falcon 9’s interstage (the top segment), landing legs, octaweb section, and raceways (the black lines traveling up and down the rocket). Compared to beat-up, older Falcon 9s, B1048’s shielded components look barely worse for wear, and it would genuinely be difficult to determine if the rocket had flown before without the telltale soot fingerprint present after every Falcon 9 recovery.

The only mystery that still remains is what exactly Falcon 9 Block 5’s octaweb heat-shielding looks like, reportedly one of the most critical and research-intensive upgrades necessary for true rapid reusability and reliability through many, many flights. Now built largely of titanium bolted to the octaweb, among a number of other extremely heat-tolerant metals and materials and even active water-cooling in spots, the new heat-shield was designed to carry the brunt of the reentry heating Falcon 9 experiences with ease.
Perhaps we’ll get a glimpse of that yet-unseen heat-shield over the next few weeks and months. Many, many more launches to come, so stay tuned!

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.

Tesla adds awesome new driving feature to Model Y
Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.
Tesla is adding an awesome new driving feature to Model Y vehicles, effective on Juniper-updated models considered model year 2026 or newer.
Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.
Tesla writes in the release notes for the feature:
“Your Tesla now provides a smoother feel as you come to a complete stop during routine braking.”

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.
