SpaceX wraps up a decade of reusable rocketry with fastest booster recovery yet
SpaceX has completed its 13th and final launch and landing of the year and decade, marked by a Falcon 9 booster’s successful return to Port Canaveral and subsequent processing to prepare it for another orbital-class mission.
Over the course of that recovery, SpaceX broke the record for the fastest Falcon 9 processing by several hours, a small but significant step towards the company’s ultimate goal of launching and landing the same Falcon 9 booster in less than 24 hours. Additionally, SpaceX appears to have finished processing booster B1056 on December 21st, the 4th anniversary of Falcon 9’s first successful landing after an orbital-class launch.
Since that first success on December 21st, 2015, SpaceX has rapidly moved through several distinct iterations of Falcon hardware, constantly improving components, systems, and the overall fit, finish, and reliability of the rocket. Over the last four years, SpaceX has landed an incredible 47 Falcon 9 and Falcon Heavy boosters as part of 60 orbital-class launches, while the company recently launched Falcon 9 B1048 for the fourth time and flew the same two Falcon Heavy boosters in April and June. Ultimately, 2019 has been a spectacularly successful year for SpaceX, and – by the numbers – 2020 is set to be several times more ambitious, still.
On December 20th, less than a day after arriving in Port Canaveral, SpaceX technicians began the process of retracting Falcon 9 booster B1056’s four deployed landing legs. As it turns out, B1056 – returning to port for the second time after its third launch – became the first Falcon 9 booster to have all of its landing legs successfully (and semi-permanently) retracted in May 2019. To accomplish the feat, SpaceX designed a custom retraction mechanism that simultaneously serves as the crane jig used to lift the booster while vertical.
“The crux of the need for a relatively complex crane-and-jig method of leg retraction rests on SpaceX’s landing leg design. Put simply, after rapidly deploying with a combination of gravity and hydraulics, Falcon 9 landing legs have no built-in way to return to their stowed state. Each of the four legs are quite large, weighing around 600 kg (1300 lb) and stretching about 10m (33 ft) from hinge to tip. They use an intricate telescoping carbon fiber deployment mechanism to give them legs enough strength to stand up to the stresses of Falcon 9 booster landings.
Combined, the legs’ size and telescoping mechanism makes the addition of an onboard retraction mechanism impractical. All the needed hardware would struggle to find a good place for installation and would quite literally be dead weight during launches and landings, stealing from Falcon 9/Heavy payload capacity and generally serving no purpose until a booster has been lifted off the ground with a giant crane.”

Impressively, SpaceX took less than an hour and a half to successfully retract all four of thrice-flown Falcon 9 B1056’s also thrice-flown landing legs. Less than three hours after the rocket’s legs were snugly retracted, SpaceX immediately attached a second crane and brought the booster horizontal. Altogether, this made Falcon 9 B1056’s third recovery the fastest SpaceX has ever performed by 3-6 hours – seemingly small progress but still no mean feat.
SpaceX’s fastest-ever Falcon 9 recovery – from the drone ship berthing to the booster departing the port on a transporter – occurred with B1049 after its third launch and landing, taking just 2.01 days (48.25 hours). Falcon 9 B1056’s third recovery appears to have beaten that record by at least several hours, brought horizontal and installed on a SpaceX transporter perhaps less than 1.75 days (42 hours) after arriving in port – more than 10% faster than B1049’s previous record.
Meanwhile, SpaceX lifted a fairing half recovered off the surface of the Atlantic Ocean by GO Ms. Tree, appearing unharmed after having potentially been dropped when the ship’s secondary (fairing) fishing net tore while moving the Falcon 9 hardware.
With any luck, that fairing half will be in good enough shape to be reused on a future Starlink mission, seemingly unlikely but proven to be well within the realm of possibility after SpaceX’s very first fairing reuse involved two halves recovered off the ocean surface after Falcon Heavy Block 5’s April 2019 debut. B1056, however, is all but guaranteed to fly again – this time on its fourth launch – in the near future. SpaceX has dozens of launches planned in 2020, so there will be plenty of opportunities.

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.
