SpaceX wins Sentinel 6B radar satellite launch contract
SpaceX has won a contract to launch the joint US-European Sentinel 6B radar satellite as early as November 2025.
Five years ago, NASA also chose SpaceX to launch Sentinel 6A, the first of two identical satellites designed to use radar altimeters to determine global sea levels more accurately than ever before. In October 2017, just half a year after SpaceX’s first Falcon 9 rocket booster reuse and well before the cost savings that followed were fully factored in, NASA awarded SpaceX $94 million to launch the 1.1-ton (~2500 lb) to a relatively low 1300-kilometer (~810 mi) orbit.
Five years and two months later, NASA has awarded SpaceX $97 million to launch a virtually identical satellite to the same orbit, from the same launch pad, with the same rocket. SpaceX, however, is far from the same company it was in 2017, and has effectively mastered Falcon booster and payload fairing reuse in the half-decade since.

Beginning in March 2017, SpaceX has reused Falcon boosters on 130 launches, including sensitive US military missions and even NASA astronaut launches. SpaceX has launched almost 70 internal Starlink missions (carrying more than 3600 SpaceX-built satellites) without bankrupting the company. CEO Elon Musk has stated that the marginal cost of a barebones Falcon 9 launch is just $15 million, while another executive once pegged the total cost of a Falcon 9 launch with flight-proven hardware at $28 million.
Perhaps most significantly, SpaceX won a contract in 2019 to launch NASA’s tiny IXPE X-ray telescope on Falcon 9 for only $50 million. SpaceX completed the mission in December 2021, launching the 330-kilogram (~730 lb) spacecraft into a roughly 600-kilometer (~370 mi) orbit. IXPE was initially expected to launch on Aerojet Rocketdyne’s troubled air-launched Pegasus XL rocket, which last launched a small NASA spacecraft for about $55 million.
Writ large, that may be the best explanation for why SpaceX and its executives – both of which have relentlessly reiterated that the company’s purpose is to radically reduce the cost of orbital launches – don’t feel pressure to translate those major cost decreases into major price cuts. Put simply, despite the fact that SpaceX has openly discussed its intentions for more than a decade, there isn’t a rocket on Earth that can beat Falcon 9’s combination of performance, cadence, reliability, and affordability.
In lieu of even a hint of competitive pressure from the rest of the industry, particularly for contracts limited to US industry, SpaceX appears to have decided that the profits from charging as much as possible outweigh the cynicism those actions could convey. To SpaceX’s credit, the reality is also more gray than some of the limited data might imply. Over the last three years, SpaceX’s prices for smallsat rideshare customers have repeatedly decreased and become more flexible. Additionally, accounting for five years of inflation, SpaceX’s $94 million Sentinel 6A contract would be worth about $114 million today, meaning that its $97 million Sentinel 6B launch contract technically represents a modest 15% discount.
It’s also likely that SpaceX’s main competitors, ULA and Arianespace, would have charged tens of millions of dollars more to launch Sentinel 6A or 6B on their current or next-generation rockets. But their existing rockets have no spare capacity for new contracts and their new Vulcan and Ariane 6 rockets have yet to fly, leaving SpaceX without any real competition.
For better or worse, it appears that Falcon 9 rideshare customers and SpaceX’s own Starlink constellation are the only major beneficiaries of Falcon 9’s extraordinary newfound affordability. With potential competitors like Rocket Lab’s Neutron, Relativity’s Terran-R, Blue Origin’s New Glenn, and ULA’s semi-reusable Vulcan variant all years from market entrance, that’s unlikely to change until the mid-to-late 2020s. Until then, even though SpaceX’s pricing is unlikely to revolutionize others’ access to space, Falcon 9 will remain an exceptionally affordable and available option for all launch customers – including NASA and ESA.

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.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…

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.
— Elon Musk (@elonmusk) March 12, 2026
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.
