SpaceX’s second Falcon 9 Block 5 booster reuse closes in as rocket refurb continues
Scheduled on October 7th, SpaceX is roughly three weeks out from the next routine launch of Falcon 9, set to carry the ~2800 kg (6200 lb) Argentinian satellite SAOCOM-1A into a low polar orbit from the company’s Vandenberg Air Force Base launch facilities.
Cocooned inside Falcon 9’s payload fairing during the final days of August, the Earth observation satellite’s launch will mark a number of exciting milestones for SpaceX, including the second reuse of a Block 5 booster and the debut of a California-based rocket landing zone barely 400m (1400ft) from the launch pad.

Previously tasked with launching Iridium’s 7th group of 10 NEXT satellites on July 25th, Falcon 9 B1048 has been assigned as SAOCOM 1A’s ride to orbit, originally expected to refly as early as September 5th and September 28th. Despite the delays, it still appears that B1048 will easily snag the SpaceX record for second fastest booster turnaround – 74 days compared to Block 5 booster B1045’s 71 days gap between launching NASA’s TESS and CRS-15 missions.
According to a number of comments from satellite engineers involved in the launch, most of the month-long slip rested on rocket availability, meaning that SpaceX was having some sort of difficulty with Falcon 9 components. Given photos and official comments showing that SAOCOM-1A was encapsulated in its payload fairing more than 5 weeks before launch (August 30th) and that Falcon 9 Block 5 is a fairly new launch vehicle, especially in a flight-proven configuration, the most logical explanation is that SpaceX is simply being extra cautious and thorough with B1048’s post-flight analysis and refurbishment.
It’s entirely possible that SpaceX engineers and technicians could have managed a ~40-day turnaround to make the original September 5 launch date, but it’s equally likely that some off-nominal characteristics were noted while the booster was being prepped for transport after craning off of drone ship Just Read The Instructions. In fact, B1048’s recovery operations were exceptionally lengthy and in-depth, including an extraordinary few hours during which technicians removed the booster’s Merlin 1D access panels, baring wholly-uncovered rocket engines in full view of a public area. Nothing equivalent has ever been observed over the course of more than a dozen Falcon booster recoveries, perhaps indicating some unique circumstances in the case of B1048.

The most obvious explanation is that those publicly-visible inspections were used to judge whether the flight-proven booster could return directly to SpaceX’s Vandenberg launch pad or needed to make a stop at the company’s dedicated Hawthorne factory and refurbishment facilities. Judging from the month-long slip that transpired, it’s probable that the latter option was selected. Regardless, caution is key when a customer’s payload is on the line.
Once it makes its way to the launch pad for the second time, B1048 will have the opportunity to both become the first Block 5 booster to land on land and the first rocket ever to land at SpaceX’s West Coast Landing Zone (LZ), under construction/development for the last two or so years. Just like its Floridan twins, the California LZ will only be an option for particularly lightweight payloads and lower-energy launch profiles, of which SAOCOM 1A (and 1B) certainly fit the bill.

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…

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.
