SpaceX releases video of world’s most powerful rocket ready for liftoff
Just a few days after its first-ever rollout to Launch Complex 39A, SpaceX has published its official photos of the historic moment, capturing Falcon Heavy poised and ready at the launch pad that could host its inaugural flight as soon as January 15th.
These photos offer the first glimpses of the complete, integrated Falcon Heavy, now with Elon Musk’s Tesla Roadster payload and second stage attached to the massive rocket. While SpaceX has not yet revealed specific details regarding the Roadster’s actual destination, it can be assumed that Falcon Heavy and its second stage will attempt to place it into an extremely stabled orbit around the sun, with one side close to the orbit of Mars. In this configuration, it’s unlikely that there will be any possibility of in-space photo opportunities with the Tesla and Mars. Musk has confirmed that its orbit will be extremely stable, and Roadster will likely remain in its final space journey for hundreds of millions or even billions of years.
With more than 5 million pounds of thrust at liftoff—equal to approximately eighteen 747 aircraft at full power—Falcon Heavy will be the most powerful operational rocket in the world by a factor of two. https://t.co/NneqPRPr46 pic.twitter.com/oswCUreG6i

While Falcon Heavy’s inaugural launch will apparently see the vehicle operating at only 92% thrust, this performance would still easily catapult the rocket above all other operational launches vehicles by nearly a factor of two.
At a total of 5 million pounds of thrust (22.8 kN), the rocket would be able to lift a fully-fueled 747 passenger jet into low Earth orbit (LEO) in an expendable configuration. Its performance with full recovery of its three first stages is not public, on the other hand, but SpaceX will nevertheless be attempting to recover all first stages alongside the inaugural launch. Approximately 30 seconds before Falcon 9’s usual main engine cut-off (MECO) point, Falcon Heavy’s twin side boosters will separate from the center core (essentially a complete Falcon 9) with the help of some form of mechanical actuators designed to gently push those boosters away from the center.
Quite frankly, the intense aerodynamic forces present at the point of side booster separation mean that it is entirely possible that they may not survive, and could even be drawn back in to impact the center core, an eventuality that would likely bring the mission to a premature end. Typically, rockets with a similar triple booster first stage (Titan IV, Delta IV Heavy) have used relatively powerful separation rockets to more sternly force the side boosters away from the main stage, generally with great success. However, the sort of single-use separation motors would run counter to SpaceX’s primary pursuit of completely reusable rockets.
Risks aside, if all goes well, the side cores will separate and return to the land-based Landing Zone-1 (LZ-1) at Cape Canaveral Air Force Station, and will likely land simultaneously and offer nearby Floridans a double dose of sonic booms as they slow down from speeds well above Mach 3. Meanwhile, the center stage will throttle up and continue on as if it were a Falcon 9. The core stage will finally separate from the second stage and Roadster payload and power back down to Earth to attempt a recovery aboard the drone ship Of Course I Still Love You. Given SpaceX’s previous history of rather exceptional live coverage of both their Falcon 9 launches and landings, fans can expect a truly stunning tour-de-force of a show if the launch goes as planned.
Even then, a failure would still be quite a spectacle and is undeniably a real possibility for any new form or iteration of a rocket. However, it is rather implausible that SpaceX would choose to take unreasonable risks with one of its invaluable launch pads, particularly LC-39A – tasked with supporting SpaceX’s upcoming Commercial Crew demonstration missions no earlier than August 2018. Musk’s hyperbole aside, he can be taken at his word when he in the past commented that the launch would be a spectacle one way or another. The massive vehicle’s first static fire attempt, the final step ahead of launch, is to occur no earlier than January 6th, 2018.
Follow along on Instagram as Teslarati’s launch photographer and correspondent Tom Cross provides behind-the-scenes live coverage of both the launch of Zuma (NET January 5) and the final operations ahead of Falcon Heavy’s first launch.

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.

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.
