SpaceX, Polaris reveal plans to launch private astronauts higher than ever before
SpaceX and Inspiration4 creator Jared Isaacman have announced the Polaris Program, an initiative designed to carry the torch forward from Inspiration4 with even more ambitious private astronaut launches.
In September 2021, four astronauts became the first all-private crew to launch into orbit on a mission known as Inspiration4. First and foremost, I4’s goal was to uplift St. Jude’s Children’s Hospital and raise money for the fight against childhood cancer. It undeniably succeeded in that regard, raising almost a quarter of a billion dollars – about half of which came from public donations. The mission also catapulted SpaceX into the spotlight and appeared to mark the very beginning of the company’s private human spaceflight ambitions.
Combined with a separate program from Axiom Space, which has already booked four fully private astronaut missions to the International Space Station (ISS), the creation of the Polaris Program appears to confirm as much.
SpaceX now has six private Crew Dragon launches scheduled within the next few years. Polaris adds at least two missions, beginning as early as Q4 2022. Known as Polaris Dawn, the mission will be Crew Dragon’s second free-flyer mission after Inspiration4, meaning that the spacecraft will fly on its own for the full five-day duration. That gives SpaceX and the Polaris team far more freedom, freedom that they plan to take advantage of.
SpaceX aspires for Polaris Dawn to be the highest Earth orbit humans have traveled to since the 1960s and the furthest humans have been from the planet since the 1970s. NASA’s Apollo missions, which sent humans to the Moon, hold the all-time record, which Polaris Dawn will barely scratch the surface of. But in Earth orbit, the record – 1368 kilometers (850 mi) – was set by Gemini XI in September 1966.
With a drone ship landing for the booster, Falcon 9 is officially capable of launching around 12 metric tons (26,000 lb) to a circular 1400 km (870 mi) orbit. For unknown reasons, SpaceX and NASA have never acknowledged Crew Dragon’s mass at liftoff, but the first uncrewed vehicle weighed around 12 tons when it docked with the ISS. As such, it’s likely that Crew Dragon weighs at least 13 tons with a full crew of four astronauts. It’s possible that SpaceX can reduce Dragon’s mass or eke out more performance from Falcon 9 with a more aggressive booster landing further downrange, allowing the Polaris Dawn crew to narrowly beat the Gemini XI record.
If SpaceX went as far as expending a well-worn Falcon 9 booster for the mission, it’s likely that the mission could double or even triple the altitude record. If, like with Gemini XI, SpaceX launched Crew Dragon into an elliptical orbit, it could likely go even higher and easily beat the Gemini record while still recovering Falcon 9’s first stage.
Beyond the aspirational record-breaking altitude, Polaris Dawn will also debut SpaceX’s custom-built EVA (extra-vehicular activity) spacesuits, which are described as an overall upgrade to and replacement for the intra-vehicular (IVA) suits that already routinely protect NASA and private Dragon astronauts. The Polaris announcement is the first time SpaceX has publicly confirmed that it’s developing its own EVA suit. If it happens as planned, Polaris Dawn will mark the first private/commercial EVA in the history of spaceflight.
Finally, Polaris has plans for not one but three private astronaut launches. The second mission will follow in the footsteps of Polaris Dawn – likely with another Crew Dragon flight, though SpaceX and Polaris haven’t settled on a choice yet. The third mission, however, aims to be the first crewed launch of SpaceX’s next-generation Starship rocket and an essential pathfinder for DearMoon, a separate Starship launch contract that aims to send a crew of artists around the Moon as early as 2023.

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.
