SpaceX’s Falcon Heavy rocket back in action after a three-year hiatus

Published

Update: The US Space Systems Command says that SpaceX’s first direct launch to geosynchronous orbit was a “simply outstanding” success, safely deploying several satellites more than 36,000 kilometers (~22,400 mi) above the Earth’s surface.

The success of the US Space Force’s USSF-44 mission means that SpaceX’s Falcon Heavy rocket is now one of just a handful of operational rockets in the world that has demonstrated the ability to launch satellites directly to geosynchronous orbit. More importantly, it’s one of just three US rockets with that established capability. The other two rockets – ULA’s Atlas V and Delta IV – will cease to be available for US military missions by the end of 2023, meaning that Falcon Heavy may briefly become the only rocket in the world able to launch certain US military missions until ULA’s next-generation Vulcan rocket is ready to prove itself.

SpaceX’s Falcon Heavy has continued a streak of successful dual-booster landings during its first attempted launch directly to geosynchronous orbit, a mission that was also the rocket’s first launch in more than three years.

Known as USSF-44 and initially scheduled to launch more than two years ago, the US Space Force mission finally lifted off on November 1st, 2022 after relentless payload delays. By mid-2021, the hardware required for SpaceX’s first Falcon Heavy launch since June 2019 – mainly three new first-stage boosters – had finished qualification testing and been shipped to Florida in anticipation of a late-2021 or early-2022 launch. That launch never came.

Only in November 2022 did most or all of USSF-44’s payloads finally come together, resulting in a gap of more than 40 months between Falcon Heavy launches as practically every other payload assigned to the rocket in the interim experience their own significant delays. Regardless, on November 1st, Falcon Heavy lifted off for the fourth time and performed flawlessly for the nine minutes the US Space Force allowed SpaceX’s webcast to continue.

Over the course of those nine minutes, Falcon Heavy’s twin side boosters – both flying for the first time – helped send the rest of the rocket on its way to space before separating from the center core, upper stage, and payload to boost back towards the Florida coast. Less than eight minutes after liftoff, they safely touched down seconds apart at SpaceX’s LZ-1 and LZ-2 landing zones. Lacking grid fins or landing legs, Falcon Heavy’s intentionally-expendable center core (middle booster) continued burning for another 90 seconds and only separated from the upper stage after reaching a speed of almost four kilometers per second (8,900 mph) – a new record for a SpaceX rocket booster.

The center core, B1066, was likely obliterated when it reentered Earth’s atmosphere traveling at approximately 50% of orbital velocity. Side boosters B1064 and B1065, however, will be rapidly refurbished for a “future US Space Force mission” that SpaceX – perhaps incorrectly – says could follow USSF-44 as early as “later this year.” Unless SpaceX has received an additional USSF launch contract in secret, the company’s next USSF mission appears to be USSF-67, which the US Space Systems Command reported could launch as early as January 2023 in their latest press release [PDF]. USSF-44 and USSF-67 are technically set to launch in the same US fiscal year but not the same calendar year.

USSF-44 is SpaceX’s first direct geosynchronous launch, meaning that Falcon Heavy is attempting to deliver the US military’s payloads to a circular geosynchronous orbit (GEO) approximately 36,000 kilometers (~22,400 mi) above Earth’s surface. “Geosynchronous” refers to the fact that a spacecraft’s orbital velocity matches Earth’s rotational velocity at that altitude, making it a popular destination for communications and Earth observation satellites that want to observe the same region of Earth all the time. Ordinarily, to simplify the rocket’s job, most GEO-bound satellites are launched into an elliptical geosynchronous or geostationary transfer orbit (GTO) and use their own propulsion to circularize that ellipse.

On a direct-to-GEO launch, the rocket does almost all of the work. After reaching a parking orbit in Low Earth Orbit (LEO), Falcon Heavy’s upper stage likely completed a second burn to geosynchronous transfer orbit. Then, while conducting a complex ballet of thermal management and tank pressure maintenance to prevent all of its cryogenic liquid oxygen (LOx) from boiling into gas and its refined kerosene (RP-1) from freezing into an unusable slush, the upper stage must coast ‘uphill’ for around five or six hours.

Over that journey from an altitude of about 300 kilometers to 36,000 kilometers, in addition to the above tasks, the upper stage must also survive passes through both of Earth’s radiation belts. At apogee, Falcon S2 must reignite its Merlin Vacuum engine for around one or two minutes to reach a circular geosynchronous orbit. Payload deployment will follow and could last anywhere from a few minutes to an hour. Finally, to be a dutiful space tenant, Falcon’s upper stage must complete at least one or two more burns to reach its final destination: a graveyard orbit a few hundred kilometers above GEO.

SpaceX’s third Falcon Heavy launch, a US Air Force mission called STP-2, was a partial dry-run of direct-to-GEO launch – albeit in low Earth orbit (LEO) instead of LEO, GTO, and GEO. During STP-2, Falcon Heavy’s upper stage completed four successful burns in three and a half hours. USSF-44 is significantly more challenging by most measures but not entirely outside of SpaceX’s range of experience. In addition to STP-2, Falcon 9 upper stages have conducted a few long-duration coast tests after completing unrelated primary missions.

In statements made to Spaceflight Now, the US Space Systems Command said that USSF-44’s two main payloads are a pair of propulsive kick stages and payload platforms, one – LDPE-2 – supplied by Northrop Grumman and the other – the “Shepherd Demonstration” – a mystery. LDPE-2 will reportedly carry three hosted payloads and deploy three rideshare satellites: likely two Lockheed Martin LINUSS-A cubesats and Millenium Space Systems’ TETRA-1. All three rideshare satellites are designed to demonstrate various new technologies, ranging from propulsion systems to avionics.

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.

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.
