SpaceX is about to stack Starship on a Super Heavy booster for the first time

After a slight delay, CEO Elon Musk says that SpaceX is now on track to stack a complete Starship prototype on top of a Super Heavy booster for the first time ever as early as Friday morning.

In the latest stage of SpaceX’s continually impressive “Starbase Surge,” the company rolled the first orbital-class Starship prototype’s aft tank section from its birthplace in the factory “midbay” to a much larger “high bay” around noon on August 3rd. Mere hours later, Elon Musk revealed that SpaceX had fitted the Starship with a full six Raptors – a first for any Starship prototype, though Super Heavy Booster 4 technically beat it to the punch with the installation of a staggering 29 Raptor engines hours prior.

The rocket’s conical nose section joined it in the high bay later that evening and SpaceX wasted no time stacking and welding the two Starship halves together early on August 4th, effectively completing the basic structure of Ship 20 (S20). After a day of final integration work, Starship S20 left the high bay around dawn on August 5th and took to the highway for a brief trip from SpaceX’s Boca Chica factory to launch and testing facilities just a mile and a half to the east.

On August 3rd, Super Heavy Booster 4 – fitted with 29 functional Raptor engines – made the same trip from build site to launch pad, where it sat on the transporter overnight. On August 4th, with slightly calmer winds, SpaceX installed the immense ~69m (~225 ft) tall rocket booster on an orbital launch mount that itself had only been installed less than a week prior.

Ship 20 arrived at the orbital launch site a few hours after heading out and was eventually moved directly beside Booster 4 and the orbital launch mount and attached to the largest crane in SpaceX’s arsenal. After several hours sitting in one place, SpaceX announced over a sitewide loudspeaker system that all further stacking operations had been called off for the day, which Musk later confirmed on Twitter was due to wind conditions at the launch site.

Had the weather cooperated, SpaceX’s plan was to install Starship S20 on top of Super Heavy Booster 4, a feat that would have marked the first time a two-stage Starship rocket has ever been fully assembled. Due to the current setup’s temporary nature, SpaceX must complete that stacking process with a vast crawler crane – the same crane used to fully assemble a ~145m (~475 ft) tall Starship integration tower visible directly behind the rocket.

Sitting on top of the fairly tall orbital launch mount, Starship S20 and Super Heavy Booster 4 will stand about as tall as that 145m launch tower, though the booster and ship itself are expected to be just shy of 120m (~390 ft) from tip to Raptor tail. Once stacked, the vehicle will be the tallest rocket assembled in the history of spaceflight.

Tesla lands regulatory green light for Robotaxi testing in new state

This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.

Tesla has landed a regulatory green light to test its Robotaxi platform in a new state, less than three months after the ride-hailing service launched in Texas.

Tesla first launched its driverless Robotaxi suite in Austin, Texas, back on June 22. Initially offering rides to a small group of people, Tesla kept things limited, but this was not to be the mentality for very long.

It continued to expand the rider population, the service area, and the vehicle fleet in Austin.

The company also launched rides in the Bay Area, but it does use a person in the driver’s seat to maintain safety. In Austin, the “Safety Monitor” is present in the passenger’s seat during local rides, and in the driver’s seat for routes that involve highway driving.

Tesla is currently testing the Robotaxi platform in other states. We reported that it was testing in Tempe, Arizona, as validation vehicles are traveling around the city in preparation for Robotaxi.

Tesla is also hoping to launch in Florida and New York, as job postings have shown the company’s intention to operate there.

However, it appears it will launch in Nevada before those states, as the company submitted its application to obtain a Testing Registry certification on September 3. It was processed by the state’s Department of Motor Vehicles Office of Business Licensing on September 10.

It will then need to self-certify for operations, essentially meaning they will need to comply with various state requirements.

This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.

CEO Elon Musk has stated that he believes Robotaxi will be available to at least half of the U.S. population by the end of the year. Geographically, Tesla will need to make incredible strides over the final four months of the year to achieve this.

Tesla is improving this critical feature in older vehicles

Tesla is set to improve a critical feature that has not been present in older vehicles with a new update.

Tesla vehicles feature a comprehensive suite of driver assistance features, some of which aid in driving itself, while others support the vehicle’s surroundings.

One of those features is that of Driver Visualization, and with the rollout of a new update, owners of Intel-based Tesla vehicles are receiving an upgrade that will come with a simple software update.

Tesla plans to use Unreal Engine for driver visualization with crazy upgrade

The update will provide new visualizations while Intel-based vehicles are in reverse, a feature that was not previously available, but will be with Software Update 2025.32.2.

The improvement was spotted by Not a Tesla App via TheBeatYT_evil:

Previously, vehicles Tesla built were equipped with Intel-based processors, but newer cars feature the AMD chip, which is capable of rendering these visualizations as they happen. They were capable of visualizations when driving forward, but not in reverse, which is what this change resolves.

It is a good sign for those with Intel-based vehicles, as Tesla seems to be paying attention to what those cars are not capable of and improving them.

This was an undocumented improvement associated with this particular update, so you will not find any mention of it in the release notes that Tesla distributes with each update.

Tesla looks to make a big splash with Robotaxi in a new market

Tesla has been transparent that it is prioritizing safety, but it believes it can expand to basically any geographical location within the United States and find success with its Robotaxi suite. CEO Elon Musk said it could be available to half of the U.S. population by the end of the year.

Tesla is looking to make a big splash with Robotaxi in a new market, as the company was spotted testing validation vehicles in one region where it has not yet launched its ride-hailing service.

After launching Robotaxi in Austin in late June, Tesla followed up with a relatively quick expansion to the Bay Area of California. Both service areas are operating with a geofence that is expansive: In Texas, it is 173 square miles, while in the Bay Area, it is roughly 400 square miles.

Tesla has been transparent that it is prioritizing safety, but it believes it can expand to basically any geographical location within the United States and find success with its Robotaxi suite. CEO Elon Musk said it could be available to half of the U.S. population by the end of the year.

There have been plenty of reports out there that have speculated as to where Tesla would land next to test Robotaxi, and Nevada, Florida, Arizona, and New York have all been in the realm of possibility. These regions will need to approve Tesla for regulatory purposes before Robotaxi can officially operate.

Tesla is still testing and performing validation in several regions, and in Tempe, Arizona, things are moving forward as a Model Y with a LiDAR rig was spotted performing ground truth for the platform:

With the LiDAR unit, many followers of the self-driving and autonomy space might wonder why Tesla uses these apparatuses during validation, especially considering the company’s stance and vision-based approach.

LiDAR is used for “ground truth,” which is basically a solidification or confirmation of what the cameras on the car are seeing. It is a great way to essentially confirm the accuracy of the vision-based suite, and will not be used on Robotaxi units used within the ride-hailing suite.

The Robotaxi platform was made available to the public earlier this month, as Tesla launched its app for iOS users.
