SpaceX nails first Falcon 9 booster launch debut in months [photos]
On December 5th, SpaceX pulled off a flawless Falcon 9 booster debut in support of the Cargo Dragon spacecraft’s CRS-19 space station resupply mission, marking the first launch of a new booster in months.
More specifically, the last time SpaceX launched a new Falcon 9 booster was on June 25th, 2019 during STP-2, Falcon Heavy Block 5’s second mission in two months. The mission featured two flight-proven side boosters – both reused from the Block 5 rocket’s April 11th launch debut – but also relied on a new center core (B1057). B1057 unfortunately failed moments before a planned touchdown on drone ship Of Course I Still Love You (OCISLY) but still technically qualifies as the last new booster launched by SpaceX prior to CRS-19.
A few days shy of six months later, CRS-19’s brand new Falcon 9 booster (and an expendable upper stage) rolled out to SpaceX’s LC-40 launch pad, confirming suspicions that the mission would use a new booster instead of twice-flown B1056.
After the booster successfully launched CRS-17 and CRS-18 in May and July 2019, both SpaceX and NASA indicated that B1056 was the most likely candidate to launch CRS-19. Plans clearly changed, although SpaceX indicated in a prelaunch conference that the booster manifest swap was purely a scheduling move and didn’t indicate any technical issues or dissatisfaction from NASA.
In the history of SpaceX booster reuse, NASA has thus far only been comfortable flying on flight-proven boosters that had previously flown NASA missions only, meaning that it will likely be at least 12-18 months before the space agency has another twice-flown Falcon 9 booster ready for a NASA mission. Regardless, the space agency has been undeniably willing to support the technology far sooner than most would have expected, given its history of extreme conservatism over the two or so decades.
Regardless, after a brief wind-related 24-hour delay, Falcon 9 B1059 lifted off for the first time on December 5th, performing perfectly and ultimately landing on drone ship Of Course I Still Love You (OCISLY) to leave the upper stage with enough fuel to perform experiments after deploying Cargo Dragon. The mission’s drone ship landing – unusual for Cargo Dragon launches – raised suspicions in the spaceflight community and SpaceX ultimately confirmed the above information, indicating that CRS-19’s upper stage would perform orbital coast tests (likely for the USAF).
As it turns out Falcon 9 B1059’s flawless landing aboard OCISLY also made it the 20th booster SpaceX has successfully recovered. All told, SpaceX has flown a total of 46 separate missions with flight-proven Falcon 9 and Falcon Heavy boosters, all of which have occurred since the technology’s March 2017 debut.
After reaching orbit for the third time ever, Cargo Dragon capsule C106 and a fresh trunk began the journey to the International Space Station (ISS) with around 2600 kg (5800 lb) of science experiments, consumables, and other cargo aboard. The spacecraft successful rendezvoused with the ISS on December 8th and was captured and berthed by the station’s massive robotic arm (Canadarm2) shortly thereafter. All told, SpaceX has now delivered roughly 41 metric tons (90,000 lb) of cargo for NASA over its 19 successful missions to the ISS.
Meanwhile, with its first launch and landing – and a relatively gentle one, at that – under its belt, Falcon 9 B1059 should theoretically be a prime candidate for rapid turnaround, although there’s a good chance that SpaceX will hold the booster to support CRS-20, Cargo Dragon 1’s last planned launch. That mission is expected no earlier than March 2020.

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.
