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 launches Powerwall Lease for affordable home backup
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk teases Tesla Roadster unveiling once again
Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.
Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
