SpaceX’s Starship Super Heavy booster needs a custom assembly tower
SpaceX CEO Elon Musk has confirmed that Starship’s Super Heavy rocket booster will get its own tower-like vehicle assembly building (VAB) – and work on the structure may have already begun.
While the only visible work SpaceX has thus far completed on its next-generation Starship launch vehicle is related to the more complex and unproven upper stage of the rocket, its Super Heavy first stage (booster) is just as critical. For SpaceX, Starship was the perfect starting point, itself following on the footsteps of a largely successful multi-year Raptor engine development program. Substantially smaller than Super Heavy and requiring 5-10 times fewer engines, Starship serves as a testbed for an almost entirely new suite of technologies and strategies SpaceX is employing to build massive rockets out of commodity steel.
In recent months, particularly following the first successful pressure test of a full-scale Starship tank section in April, SpaceX has effectively proven that those uncharacteristically cheap and simple materials and methods can, in fact, build rocket structures that should stand up to orbital spaceflight. In theory, aside from the booster’s 31-engine thrust structure, the same methods and materials used to build Starships can be applied unchanged to manufacture Super Heavy. The booster’s almost unfathomable size, however, will necessitate its own dedicated assembly facilities.

While Starship itself is not exactly small at ~50m (165 ft) tall and 9m (30ft) wide, the Super Heavy booster tasked with launching the ship on its way to orbit will easily be the largest individual rocket stage ever built. Currently expected to measure 70m (230 ft) tall, Super Heavy – just the first stage of the Starship launch vehicle – will already be as tall as an entire Falcon 9 or Falcon Heavy and weigh roughly three times more than the latter triple-booster rocket when fully fueled. At liftoff, Super Heavy will produce more than triple the thrust of Falcon Heavy and double the thrust of Saturn V, the most powerful liquid-fueled rocket to reach orbit.


Thanks to the sheer size of the booster, SpaceX’s existing Starship-sized vehicle/vertical assembly building (VAB) is far too small for Super Heavy and is even too short to fully stack a ~50m Starship. SpaceX’s contractor of choice started assembling that VAB around January 15th and the facility was able to begin supporting its first Starship stacking and welding operations on March 2nd, just a month and a half later, with the structure fully completed by March 18th. As such, assuming the in-work foundation is as close to completion as it seems and SpaceX uses the same contractor for the next building, Super Heavy’s VAB could be ready to build the first massive booster prototype as early as July or August. Things could take a bit longer given that Musk says the booster VAB will be 81m (265 ft) tall, nearly twice the height of Starship’s VAB, but likely by no more than a few weeks.
That timeline meshes well with a senior SpaceX engineer and executive’s recent suggestion that the first orbital Starship launch attempt could still happen before the end of the year. Of course, for Super Heavy to become a genuine priority for SpaceX and receive the resources necessary to achieve that extremely ambitious goal, Starship will have to perform almost flawlessly during a series of increasingly challenging tests planned over the next few months. First up, SpaceX needs to finish repairing the launch pad after Starship SN4 exploded during testing and Starship SN5 needs to be transported to the pad to complete acceptance tests, static fire(s), and its first 150m (~500 ft) hop test. After that, SpaceX will either move on to a 2 km (1.25 mi) hop or a more ambitious 20 km (12.5 mi) flight designed to test Starship’s skydiver-like approach to landing.
If Starship SN5 or SN6 manage to complete those aforementioned tests, the horse may actually be in front of the cart for Super Heavy prototype production and Starship’s first orbital launch attempt.

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.

Lucid unveils Lunar Robotaxi in bid to challenge Tesla’s Cybercab in the autonomous ride hailing race
Lucid’s Lunar robotaxi is gunning for Tesla’s Cybercab in the autonomous ride hailing race
Lucid Group pulled back the curtain on its purpose-built autonomous robotaxi platform dubbed the Lunar Concept. Announced at its New York investor day event, Lunar is arguably the company’s most ambitious concept yet, and a direct line of sight toward the autonomous ride haling market that Tesla looks to control.

At Lucid Investor Day 2026, the company introduced Lunar, a purpose-built robotaxi concept based on the Midsize platform.
A comparison to Tesla’s Cybercab is unavoidable. The concept of a Tesla robotaxi was first introduced by Elon Musk back in April 2019 during an event dubbed “Autonomy Day,” where he envisioned a network of self-driving Tesla vehicles transporting passengers while not in use by their owners. That vision took another major step in October 2024 when, Musk unveiled the Cybercab at the Tesla “We, Robot” event held at Warner Bros. Studios in Burbank, California, where 20 concept Cybercabs autonomously drove around the studio lot giving rides to attendees.
Fast forward to today, and Tesla’s ambitions are finally materializing, but not without friction. As we recently reported, the Cybercab is being spotted with increasing frequency on public roads and across the grounds of Gigafactory Texas, suggesting that the company’s road testing and validation program is ramping meaningfully ahead of mass production. Tesla already operates a small scale robotaxi service in Austin using supervised Model Ys, but the Cybercab is designed from the ground up for high-volume, low-cost production, with Musk stating an eventual goal of producing one vehicle every 10 seconds.

At Lucid Investor Day 2026, the company introduced Lunar, a purpose-built robotaxi concept based on the Midsize platform.
Into this landscape steps Lucid’s Lunar. Built on the company’s all-new Midsize EV platform, which will also underpin consumer SUVs starting below $50,000. The Lunar mirrors the Cybercab’s core philosophy of having two seats, no driver controls, and a focus on fleet economics. The platform introduces Lucid’s redesigned Atlas electric drive unit, engineered to be smaller, lighter, and cheaper to manufacture at scale.
Unlike Tesla’s strategy of building its own ride hailing network from scratch, Lucid is partnering with Uber. The companies are said to be in advanced discussions to deploy Midsize platform vehicles at large scale, with Uber CEO Dara Khosrowshahi publicly backing Lucid’s engineering credentials and autonomous-ready architecture.
In the investor day event, Lucid also outlined a recurring software revenue model, with an in-vehicle AI assistant and monthly autonomous driving subscriptions priced between $69 and $199. This can be seen as a nod to the software revenue stream that Tesla has long championed with its Full Self-Driving subscription.
Tesla’s Cybercab is targeting a price point below $30k and with operating costs as low as 20 cents per mile. But with regulatory hurdles still ahead, the window for competition is open. Lucid’s Lunar may not have a launch date yet, but it arrives at a pivotal moment, and when the robotaxi race is no longer viewed as hypothetical. Rather, every serious EV player needs to come to bat on the same plate that Tesla has had countless practice swings on over the last seven years.
