United Launch Alliance successfully test fires new Vulcan rocket
United Launch Alliance successfully test-fires new Vulcan rocket
Following a successful Flight Tanking Test (FTT), United Launch Alliance fired up the Vulcan rocket for the first time last night. The two Blue Origin-built BE-4 rocket engines ignited for 6 seconds and pushed ULA closer to their maiden launch of the rocket.
United Launch Alliance stated they are more than 98 percent through the qualification program for Vulcan, and after reviewing data from the Flight Readiness Firing (FRF) and closing the Centaur V anomaly investigation, they will then announce launch plans.

During this test firing, the BE-4 engines ignited at T- 4.88 seconds and ramped up to 60% power for 2 seconds before powering down.
The United Launch Alliance Vulcan Centaur rocket has faced many delays leading up to this moment, most recently experiencing an anomaly of the Centaur V upper stage that was undergoing qualification testing at the Marshall Space Flight Center in Alabama.
ULA is currently conducting an investigation into the cause of the anomaly, and according to ULA CEO Tory Bruno, they found the issue was on the Centaur upper stage itself, but they are still determining if changes will need to be made to its current flight article that is stacked on Vulcan.

Prior to this unexpected issue, Blue Origin originally had planned to deliver two of their flight-ready BE-4 engines to ULA for integration onto the Vulcan rocket by 2020, but various delays in qualifications and testing meant their delivery slipped significantly to late 2022.
Following their integration onto the Vulcan rocket’s first stage, it was then shipped aboard ULA’s ‘RocketShip’ down the Mississippi River, through the Gulf of Mexico, and after rounding the southern tip of Florida to Port Canaveral, Florida, after which it was unloaded and then transported to the Vertical Integration Facility at Cape Canaveral Space Force Station.

This FRF test comes before the planned Summer launch of Vulcan Centaur carrying Astrobotics Peregrine Lunar lander and Amazon’s first two Kuiper satellites, their answer to the SpaceX Starlink satellite constellation.
Also known as the CERT-1 flight, the Vulcan Centaur rocket needs to perform 2 successful launches to qualify to launch national security payloads for the U.S. Space Force and other government payloads.
The second flight will feature the first launch of the Sierra Space Dream Chaser space plane, which will deliver supplies to the International Space Station. As of now, the majority of the payload manifest for Vulcan Centaur is Amazon’s Kuiper satellite constellation and U.S. Space Force national security missions.
The Vulcan Centaur rocket has a few configurations available to suit multiple payload sizes, the rocket can fly with just the 2 BE-4 engines delivering 1.1 million pounds of thrust at sea level to flying with 2, 4, or 6 solid rocket boosters and with 6 SRB’s it would bring its thrust up to 3.8 million pounds.
This would make the Vulcan Centaur capable of delivering 60,000 lbs (27,200 kg) to low Earth orbit or 25,400 lbs (11,500 kg) to the Moon. ULA is also working toward its SMART re-use system, which will allow the 2 BE-4 engines to separate from the first stage, and after an inflatable heatshield deploys, they would return to Earth and splash down for recovery and refurb for their next mission.
However, it is unknown when ULA will begin using this capability.

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.
