SpaceX’s next West Coast Starlink launch is heading to an unexpected orbit

Published

on

SpaceX has unexpectedly changed the Earth orbit its next Starlink launch is targeting.

Like all planned Starlink launches, the latest batch of satellites will ultimately raise themselves into a circular orbit around 550 kilometers (~340 mi) above Earth’s surface. However, beyond the basic orbital altitude, the mission will be completely different than previously expected.

Before SpaceX released details about the launch, which is now scheduled no earlier than (NET) 1:46 am PDT (UTC-8) on Friday, December 17th 1:24 am PDT (09:24 UTC) on Saturday, December 18th, it was believed the mission was called Starlink 2-3, or the third launch of a second ‘shell’ or group of satellites. SpaceX’s initial ~4400-satellite Starlink constellation is distributed into five different ‘shells’ – all with similar orbits between 540 and 570 km. What mainly differentiates each shell is orbital inclination, which refers to the tilt of an object’s orbit around a celestial body.

Contrary to what most expected, instead of the second dedicated Starlink launch for the constellation’s 70-degree shell (“Group 2”), SpaceX’s December 17th launch – known as Starlink 4-4 – will actually carry the third batch of “Group 4” satellites to an inclination of 53.22 degrees. Aside from once again skipping over Starlink 4-2, which has yet to launch for unknown reasons and was already leapfrogged by Starlink 4-3 earlier this month, Starlink 4-4 will also be launching out of SpaceX’s West Coast pad, while all thirty-one other dedicated 53-degree Starlink missions have launched out of Cape Canaveral, Florida.

A 53-degree launch out of Vandenberg Space Force Base, California is unusual because, up to now, it’s been unable to regularly launch to inclinations lower than approximately 56 degrees. Any lower (further east) and the rocket would end up overflying populated areas in Baja California or even the southwest coast of Mexico. For obvious reasons, the US FAA and other countries are not a fan of having what amounts to a high-velocity explosive device fly over populated areas.

The only apparent way SpaceX could launch to 53 degrees from Vandenberg is if Falcon 9 performs a dogleg maneuver several minutes after launch, effectively conducting a (slight) left turn mid-flight. While seemingly simple, even a minor few-degree dogleg maneuver can cost an intuitively large amount of delta-V, potentially significantly reducing the amount of payload a rocket can launch to a given orbit. For Starlink missions, maximizing payload to orbit is perhaps the single most important way (beyond reusability) SpaceX is able to reduce launch costs.

However, according to the prelaunch information SpaceX provided Celestrak, Starlink 4-4 will launch 52 V1.5 satellites into orbit – just one less than an equivalent launch (Starlink 4-1) from the East Coast. If SpaceX only needs to reduce an optimal stack of 53 V1.5 satellites to 52 to pay for Starlink 4-4’s dogleg maneuver, it’s technically only raising the average launch cost per satellite or unit of network bandwidth by less than 2%. That’s not a bad trade given that it could allow SpaceX to expand the number of launch pads capable of supporting the most common Starlink launches from two to three – a 50% increase. At the end of the day, deploying as many mid-inclination Starlink satellites as quickly as possible is likely the fastest way to expand network capacity, add Starlink subscribers, and thus grow revenue.

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.

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.

Tesla V2L adapter for Model Y stirs up a new complaint among owners

Published

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:

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.

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:

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.
