SpaceX installs Starship Mk1 rocket’s flaps for the second time in build-up to flight debut
A little over a month after SpaceX CEO Elon Musk presented an update on Starship in Boca Chica, Texas and technicians dressed the rocket up for the show, SpaceX has begun to install Starship Mk1’s flaps for the second time.
This time, with any luck, those flaps are here to stay until Starship Mk1’s inaugural launch debut, an ambitious flight test with a target altitude of 20 km (12 mi).
Around the second half of September, SpaceX technicians appeared to begin working around the clock to fully assemble Starship, outfitting the exterior with the beginnings of plumbing, power lines, and avionics harnesses, stacking the Mk1 prototype’s two halves, and installing the vehicle’s large fore and aft flaps. During SpaceX CEO Elon Musk’s September 28th Starship update, what looked to be the largely finished Starship Mk1 served as the main backdrop – an undeniably impressive one, at that.
As would soon become clear, SpaceX’s September 2019 Starship Mk1 integration was actually more of a mock-assembly – all the parts involved appear to genuinely be real flight hardware, but almost all of it was only temporarily attached to Starship to give the partial appearance of a finished ship. By October 1st, technicians began removing Starship Mk1’s four flaps, flap shrouds, and leg shrouds, finally culminating in the separation of the rocket prototype’s upper and lower halves.
The fact that neither Musk or SpaceX spokespersons noted that Starship wasn’t actually complete is at least a little unsavory, although it’s admittedly unsurprising given CEO Elon Musk’s known affinity for grand gestures and events. On a positive note, Starship’s mock-assembly likely served as an excellent learning experience for the Boca Chica team and thankfully only seems to have caused a week or two of delay.
Rapid progress in Boca Chica
Despite the mild disruption of dressing Starship Mk1 up for Musk’s presentation, SpaceX Boca Chica has made a huge amount of progress in the five weeks since. Barely three weeks after the rocket’s forward flaps (canards) were removed, SpaceX technicians began the reinstallation process with one major visible difference: a massive motorcycle-sized actuator.
On the first round of installations-for-show, Starship Mk1’s flaps featured no such mechanism, confirming suspicions that much of the hardware installed at the last second was not quite finished or was only being installed for Musk (and practice). The appearance of a previously unseen actuator mechanism on the first reinstalled canard suggests that this time around, SpaceX is installing Starship’s flaps with their final purpose of controlling Starship’s free-fall in mind.
Instead of copying Falcon 9’s proven method of vertical launch and vertical landing, SpaceX is taking a more radical approach with Starship that will see the spacecraft reenter Earth’s atmosphere belly-first, slow its forward speed to near-zero, and fall directly down for approximately 25 km (15.5 mi), using its flaps like a skydiver’s limbs. Perhaps just a few hundred meters above the ground, Starship will finally perform an aggressive flip maneuver, igniting its Raptors while sideways, swerving to neutralize that horizontal velocity, and finally landing on six small legs.
In this sense, although they certainly look the part, Starship’s aerodynamic control surfaces are very explicitly not wings and are instead meant to interact with the atmosphere at an almost 90-degree angle of attack (AoA). In line with that strategy, they only have to actuate with a single degree of freedom, drastically simplifying Starship’s control surfaces.
Similar to Starship Mk1’s newly filled-out canard actuators, SpaceX technicians have installed two massive hinges/mounts for Starship’s larger after flaps. Aft flap installation will likely start as soon as SpaceX technicians have installed the bulk of Starship Mk1’s external plumbing and wiring, a milestone that appears to be fast approaching.
Starship Mk1’s lower half was unexpectedly moved about a mile to SpaceX’s nearby launch facilities prior to the installation of its nose section, meaning that SpaceX will likely have to transport the nose to the launch pad for final mating. It’s unclear what tests SpaceX specifically plans to kick off Starship Mk1’s pre-flight preparations with, but it’s safe to assume that the most imminent milestone is a wet dress rehearsal (WDR), possibly preceded by a tank proof test.
The latter procedure would be designed to prove that Starship Mk1’s pressure vessel is both leakproof and structurally sound and would nominally involve filling the spacecraft’s tanks with a neutral fluid (likely water or liquid nitrogen). A WDR would see SpaceX load Starship as if preparing for launch (requiring liquid oxygen, methane, nitrogen, and helium) but stopping just prior to the engine ignition and liftoff that would otherwise follow. Although unlikely, a WDR could result in a massive fire or explosion if Starship were to lose structural integrity during the test, which is why the aforementioned neutral testing is typically performed first when handling brand new launch vehicles.
Finally, assuming Starship Mk1 successfully passes the above tests, SpaceX will use the vehicle to perform Raptor’s first triple-engine static fire test. That static fire will likely be the final major test activity before SpaceX readies Starship Mk1 for its 20-km flight debut, which will serve as a more or less full-fidelity test of Starship’s exotic skydiver-like landing.
Regardless of how exactly Starship Mk1’s imminent test campaign will play out, SpaceX has road closures scheduled on November 7th, 8th, and 12th. Right now, it’s anyone’s guess what is planned for Thursday and Friday, but it could potentially involve a tank proof test, launch pad checkouts, propellant loading, or something more benign, like transporting Starship’s nose section to the pad for final installation.

Tesla finally got its Nevada Robotaxi Permit but with a few catches hard to miss
Nevada granted Tesla’s robotaxi permit, but capped the fleet at just ten vehicles for now.
Tesla has received its robotaxi permit in Nevada, more than two months after regulators closed the public comment period on the company’s application. News of the approval surfaced Wednesday night when Tesla investor and longtime company watcher Sawyer Merritt posted a copy of the interim order, and the Nevada Transportation Authority’s own carrier registry now lists the permit, AVNC Permit 002 under Docket 26-05015, as active for Tesla Robotaxi, LLC.
Tesla asked Nevada in June for authority to run up to 5,000 vehicles in Clark County within a year, however the permit the NTA issued is initially capping Tesla at ten fully autonomous vehicles and confines them to a defined geofence along the Las Vegas Strip corridor. Any expansion of that operating area, or any increase to the fleet size, requires the NTA’s approval first.

The order also sets rules that look more restrictive than what Tesla runs in Austin. Rides are barred on roads with posted speed limits above 45 miles per hour, pickups are off limits within a quarter mile of Harry Reid International Airport without separate authorization, and every vehicle has to carry visible “Robotaxi” markings while notifying riders before each trip that no one is driving. The order also requires “appropriate human supervision”, language that suggests Nevada isn’t ready to let Tesla offer the rides without a safety monitor that it has run in parts of Austin since January. As with standard protocol with robotaxi services, Tesla must report any accident, system failure, or vehicle that becomes stranded on a Nevada road within five business days.
Tesla is entering a market Nevada already knows well. Zoox, the Amazon owned robotaxi company, has run its own autonomous vehicle permit in the state since last year, building up to roughly 100 vehicles and 350,000 rides along the Strip. That history likely explains why the NTA started Tesla at ten cars rather than the fleet size the company asked for. The agency has a template for scaling a permit up once a company proves out its safety record.
Tesla’s Nevada application first surfaced in June, when the company filed for the permit alongside plans for a maintenance hub in southwest Las Vegas. The company has said it won’t meaningfully scale its robotaxi fleet anywhere until FSD v15 ships, expected in late 2026 or early 2027, which makes the ten vehicle cap less of a constraint today than it might look on paper. For now, Tesla has the legal right to start Nevada rides. Whether it starts before FSD v15 arrives is a separate question the permit doesn’t answer.
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 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 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.
