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.

SpaceX just launched a secret payload from California
SpaceX launched a classified Space Force mission from Vandenberg, revealing almost nothing about its payload.
SpaceX launched a classified Falcon 9 mission for the U.S. Space Force from Vandenberg Space Force Base on Saturday night, and the government released almost nothing about what was on board. The mission, designated USSF-366, lifted off from Space Launch Complex 4E with a window that opened at 9:52 p.m. ET and ran into the early hours of Sunday, according to SpaceX’s own mission page, which described the payload only as classified. SpaceX confirmed the launch on its X account and pointed viewers to a livestream that began roughly ten minutes before liftoff.

The lack of detail did not stop analysts from filling in the blanks. Independent tracking of the rocket’s stage drop zones matched the pattern SpaceX has used on previous Starlink Group 15 missions, according to reporting from Outer Space Today, which pointed to Starshield as the likely payload rather than a one off government satellite. Starshield is SpaceX’s national security product, a version of the Starlink satellite bus built to Pentagon specifications for earth observation, communications and hosted payloads. Unlike consumer Starlink, government agencies do not have to disclose what Starshield satellites are actually doing once they reach orbit.
USSF-366 is the latest entry in a steady flow of classified and semi classified work between SpaceX and the Space Force. The company picked up a $178.5 million task order in April to launch missile tracking satellites for the Space Development Agency, as Teslarati reported at the time, and followed that in July with a $1.6 billion award covering 18 more Falcon 9 missions from Vandenberg through the end of 2027, also detailed by Teslarati. Add those contracts up and SpaceX’s Pentagon business for 2026 alone tops $8 billion.
SpaceX scores another massive Pentagon deal to support military satellites
The Falcon 9 that flew Saturday landed back near the launch site, producing the sonic booms that have become routine for residents near Vandenberg. What is less routine is how little the public will likely ever learn about what the rocket carried. SpaceX and the Space Force have not confirmed the Starshield connection, and government satellite programs built on commercial buses rarely get identified beyond a mission number and a general orbit. For a company that live streams almost everything else it does, from Starship test flights to Optimus robot demos, USSF-366 is a reminder that some of SpaceX’s busiest work now happens entirely out of public view.
On Friday, Tesla launched the Outlet Adapter that enabled Vehicle-to-Load (V2L) energy transfer, meaning owners could essentially utilize their cars as a power source for things like laptops, electric grills, or string lights.
However, even owners of some of the newest builds of the Model Y are finding out that their cars are not compatible with the new $80 accessory, stirring up a new complaint among members of the community.
Tesla launches V2L Outlet Adapter for Premium Model Y in the U.S.
Upon the release of the Outlet Adapter on Friday, I signed into my Tesla account to order the accessory. However, I was met with the dreaded “This product is not compatible with your 2026 Model Y” message at the bottom of the screen.
Some said their accounts also displayed the same message, but they ordered anyway. However, they might be surprised to find that this is no mistake; some of the newest Model Ys do not have the appropriate Power Conversion System (PCS). Mine, which was ordered on this day last year and delivered on August 31, has the old 48A, single-phase PCS.
Vehicles with the new, two-piece PCS are able to utilize V2L features on their cars:
🚨 Looks like you can hit the Parts Catalog and enter your VIN and check to see if your Model Y will be able to use the adapter for V2L.https://t.co/QA9zRk7n2k
h/t to @SawyerMerritt for finding this out.
I am sad but this isn’t a huge loss. https://t.co/AYpI12QVV9 pic.twitter.com/LRFSrtRywo

Obviously, it’s disappointing. Many owners have taken delivery this year and still can not utilize the Outlet Adapter because their cars feature the old PCS:

It looks like if you have one of these older PCS units, you can upgrade, but the parts alone are $1,750, and that’s before Tesla adds labor for installing. It is honestly more logical to get some kind of portable power supply or power station at that point.
It is great that Tesla has enabled V2L for Model Y vehicles, but it is also unfortunate that vehicles that are less than one year old are not able to take advantage of this awesome new feature.
With that being said, it truly is a first-world problem; can you really complain when Full Self-Driving is available, maintenance is incredibly inexpensive, and the car has been so good through a year of ownership?
Tesla has launched a new Vehicle-to-Load (V2L) Outlet Adapter for Premium Model Y vehicles in the United States, meaning you can now power devices like laptops or light strings with your vehicle’s battery.
It appears the capability will be available for any Model Y Premium trim, including those that were purchased prior to the Adapter being launched. It will also only impact Juniper Model Y vehicles, so the first-gen owners will unfortunately not have access to this capability.
If your Model Y was purchased before Tesla renamed the trim levels to “Premium” and “Standard,” it does not seem to be compatible. My Model Y is technically a Premium build, as it is the Long Range All-Wheel-Drive. However, Tesla says it is not compatible with my vehicle.
🚨 Tesla has launched the Outlet Adapter for Model Y Premium in the U.S., enabling V2L capability for all Premium trims (that’s what it appears to be as it is available for purchase with all Premium trims)
It’s available for $80. 2.4kW max power and rated for 120v, 20A pic.twitter.com/lDxlVIk5s8

For $80, you can now utilize your car as a portable charger for small appliances or devices. This is perfect for things like tailgates, concerts, or camping, as you can now plug in devices that you might use. Those string lights for camping? That laptop for the other games that are on at the tailgate?
They’ll both utilize energy from your Tesla’s battery to be powered. This is the first time Tesla has expanded the capability to vehicles outside of the Model Y Performance and Cybertruck. However, this feature has been highly requested by owners for an extended period of time.
Tesla launched the Outlet Adapter in China last year:
Tesla China rolls out Model Y L V2L adapter, and it’s free for early owners
You will need the Mobile Connector to operate the Outlet Adapter: the Outlet Adapter will plug into the main housing of the Mobile Connector, where the appropriate adapter to charge your vehicle will plug in.
It is rated for 120 volts and 20 amps, and has a max power rating of 2.4kW.
You can buy it here from Tesla for $80.
