After a few late-stage schedule tweaks, SpaceX’s third Falcon Heavy launch – set to deliver 24 spacecraft to a variety of orbits – is ready to usher the US Air Force into a new age of commercial rocket reuse as early as 11:30 pm ET (03:30 UTC), June 24th.

Split among the USAF, Department of Defense (DoD) research labs, NASA, NOAA, and a few US universities, STP-2’s 24 satellites will launch aboard SpaceX’s second Falcon Heavy Block 5 rocket. Both side boosters are flight-proven, having supported Falcon Heavy Block 5’s launch debut on April 11th, just 54 days ago. If all goes as planned, STP-2 will simultaneously give the USAF the data it needs to fully certify Falcon Heavy for all military launches and set the US military up to certify flight-proven commercial rockets for future launch contracts.

Signalling just how important the company feels this mission is, a dedicated STP-2 website created by SpaceX offers an excellent explanation of all aspects of the mission, from the technical to the strategic.

The STP-2 mission will be among the most challenging launches in SpaceX history with four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver and a total mission duration of over six hours. In addition, the U.S. Air Force plans to reuse side boosters from the Arabsat 6A Falcon Heavy launch, recovered after a return to launch site [RTLS] landing, making it the first reused Falcon Heavy ever flown for the U.S. Air Force.

[STP-2] will demonstrate the capabilities of the SpaceX Falcon Heavy launch vehicle and provide critical data supporting certification for future National Security Space Launch (NSSL) missions. In addition, [the Air Force Space & Missile Systems Center (SMC)] will use this mission as a pathfinder for the development of mission assurance policies and procedures related to the reuse of launch vehicle boosters.

Following the ~June 1st arrival of Falcon Heavy center core B1057, all STP-2 launch hardware is now on site at SpaceX’s Pad 39A launch complex and nearby payload processing facilities. Although we will have to wait for official photo confirmation, SpaceX is likely in the late stages of integrating Falcon Heavy’s three boosters and upper stage, while some combination of DoD and SpaceX technicians are presumably in the middle of preparing all 24 STP-2 satellites for launch.

Falcon Heavy Flight 3’s next visible milestone will probably be the integrated rocket’s roll-out to Pad 39A for a routine static fire test, likely to occur 3-7 days prior to June 24th.

Record-breaking reusability

Incredibly, despite the schedule overhead likely added by this mission’s crucial pathfinder nature, the current June 24th launch date would permit side boosters B1052 and B1053 to simultaneously break SpaceX’s current booster turnaround record. Set in mid-2018 by B1045 on SpaceX’s last non-Block 5 launch, the record turnaround (time between launches) of 72 days would be beaten at 68 days for STP-2, barring any additional delays.

Whether STP-2’s side boosters literally beat SpaceX’s 72-day reusability record is immaterial to the actual significance of this milestone. If SpaceX can beat its old record as part of what is arguably its most complex launch ever, it’s safe to say that Block 5 reusability – particularly for gently-used boosters – is already a spectacular success. It also suggests that SpaceX technicians and launch engineers are becoming extremely familiar and comfortable with Falcon Heavy launch operations, to the extent that two boosters used on two Falcon Heavy launches could break SpaceX’s most significant reusability record.

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.

Tesla announces massive investment into xAI

At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.

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.

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 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 set to activate long-awaited Cybertruck feature

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 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.

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.
