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

Tesla gives the Roadster an official “Go for launch” demonstration date
Tesla teased an October 1 Roadster reveal, reviving years of delayed SpaceX thruster hover promises.
Tesla teased an October 1 event date for its next generation Roadster, posting an image on X Saturday that shows the car lit up like it is sitting on a launch pad, with the date “10.01” stamped across the bottom and the caption “Go for launch.” A countdown clock on Tesla’s Roadster order page now points to the same date, which falls on a Thursday. The company has not said where the event will happen or whether it will be streamed at the moment. Stay with us @Teslarati for live updates.

Tesla has since sent formal invitations to reservation holders confirming the event will take place in Waco, Texas, about 90 minutes north of its Austin headquarters, based on a digital ticket shared on X by Sawyer Merritt. Tesla did not name the exact venue, though Waco sits close to SpaceX’s McGregor, Texas, rocket test site, previously reported as the planned location for a Roadster thruster demonstration. The invite sets the reveal for 8:30 p.m. Eastern on October 1, requires RSVPs by midnight on September 16, and limits entry to guests 21 and older. Invitations are non-transferable.
The tease follows nine years of a project defined by unimaginable specs along with slipped dates. Musk first showed the second generation Roadster in November 2017 as a surprise reveal at the end of the Tesla Semi event, promising a 0 to 60 mph time under two seconds, a top speed above 250 mph, 620 miles of range from a 200 kWh battery, and production starting in 2020. At last November’s shareholder meeting, Musk set an April 1 demo date and joked the choice gave him “deniability” if it slipped again, which it did, moving first to late April, then to “a month or so,” then to August.
Tesla Roadster SpaceX Package’s 1.1-second 0-60 mph launch visualized in concept video
Whatever Tesla shows on October 1 is expected to center on the SpaceX developed thruster package Musk has described since 2018. Internally code named A71, a nod to the Lockheed SR-71 Blackbird, the system reportedly uses cold gas thrusters fed by a composite overwrapped pressure vessel, the same tank design SpaceX uses on Falcon 9. Musk has said a thruster equipped Roadster could hit 60 mph in about 1.1 seconds under roughly 2.75 g of launch force, well past the 1.9 second figure quoted for the standard car. That version reportedly will not be street legal and has reportedly been discussed as a limited run sold through a track only program.
The standard Roadster is still expected to carry the original $200,000 base price and $250,000 Founders Series tier, both set when Tesla opened $50,000 and $250,000 reservations in 2017. Tesla VP of Vehicle Engineering Lars Moravy has confirmed production will happen at Gigafactory Texas, with Musk targeting 2027 or 2028, 12 to 18 months after whatever the company demonstrates next month.
Tesla is planning to roll out some pretty significant safety and accident avoidance features with Full Self-Driving version 15, which will be the next major FSD deployment from the company.
Tesla AI lead Ashok Elluswamy used a near-miss this week to preview what the company says is the next leap in Full Self-Driving.
In response to a driver whose car had swerved away from another vehicle pulling out of a parking lot, Elluswamy wrote that he was glad the owner was safe and that “even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance” would arrive with FSD v15.
Glad you are safe. Even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance coming as part of the next big upgrade (v15).

The comment landed as Tesla continues to treat software as the primary safety upgrade path. v15 is described internally as a larger architectural step, with a much bigger neural network and tighter coupling between prediction and control.
The company has already begun using early v15 software in some robotaxi operations while rolling out safety features such as Automatic Collision Evasion into current customer cars, allowing the driving stack to intervene even when the driver is in manual control.
Tesla is rolling out a new FSD version with a massive safety addition
Tesla’s published telemetry is the backbone of its safety argument. In recent North American Vehicle Safety Report data, vehicles with FSD (Supervised) engaged traveled roughly 5.1 million to 5.7 million miles between major collisions, defined as airbag-deployment events.
Tesla’s estimate of the U.S. average over the same period is about 699,000 miles per comparable crash. That is the comparison Tesla often frames as roughly seven times fewer major collisions.
A tighter comparison uses the same Tesla fleet. Cars driven manually with active safety features such as automatic emergency braking still recorded a major collision about every 2.1 million miles. Against that baseline, FSD’s advantage shrinks to roughly 2.4 to 2.7 times fewer severe crashes, which independent researchers argue is the more apples-to-apples figure.
European data released in 2026 pointed in the same direction: Tesla reported FSD as 3.5 times safer than manual driving in the Netherlands and 4.1 times fewer collisions than manually driven Teslas with active safety across more than 100 million kilometers in five approved countries.
Those numbers do not settle every debate. NHTSA’s Standing General Order still shows Tesla accounting for the large majority of U.S. Level 2 driver-assist crash reports, in part because the fleet logs far more assisted miles than rivals. Critics also note that Tesla’s “U.S. average” mixes crash definitions and driving mix.
Even so, Tesla’s own same-car comparisons, plus lower rates of automatic emergency braking and harsh maneuvers when FSD is engaged, are the evidence Elluswamy is pointing to when he says v15 will push prediction and collision avoidance further. The claim is not that software already eliminates risk. It is that each major version is meant to widen the gap between the system and an unaided human driver.
Cybertruck
Tesla’s most delayed Cybertruck feature is finally here
Tesla finally links Cybertruck Powershare with Powerwall 3 for extended home backup after years overdue.
Tesla’s Cybertruck can now pair with a Powerwall 3 to keep a house running longer during an outage, a feature the company first promised when the truck launched in November 2023.
The official Cybertruck account posted the update on X Thursday: “Powerwall 3 & I can now power your house together. This extends your home backup by over 3 days, equivalent to 9 additional Powerwalls,” Cybertruck lead engineer Wes Morrill confirmed the rollout separately, calling it the first time a vehicle and a home battery have worked together this way. Powerwall 2 and Powerwall+ compatibility is still coming later this year, per both the Cybertruck account and Morrill.

Powershare itself is not new. Tesla enabled the version that lets Cybertruck power tools, appliances or another EV through its bed outlets when the truck launched in 2023. Home backup through a Powershare Gateway and Universal Wall Connector arrived in 2024, and Tesla extended that support to homes with solar the following year. What has been missing until now is Powershare working alongside an existing Powerwall, instead of functioning as a separate backup source competing for the same job.
The pairing matters because a single Powerwall home battery typically covers a home for about a day, less if usage is heavy or the outage stretches into a heat wave or freeze. A second Powerwall for more backup storage costs several thousand dollars installed. A Cybertruck instead uses a battery the owner already has, one large enough here to add roughly three more days of backup without mounting another unit or booking an installer visit. For households in wildfire, hurricane or winter storm regions where outages run past a day, that keeps the refrigerator and medical equipment running instead of shutting down.
The company told owners in October 2024 that Powerwall integration was coming sometime in 2025. That date passed, and in December 2025 Tesla pushed the target to mid-2026, with Morrill explaining at the time that two grid-forming devices need to negotiate which one manages a home during an outage, and that certifying the process across multiple generations of Powerwall took longer than expected.
For owners who bought Powershare hardware expecting it to work with whatever battery setup they already had, Thursday’s update closes a gap that has shown up repeatedly in owner complaints since Cybertruck deliveries began. Tesla has also rolled out a separate Powershare grid support program in Texas, letting Cybertrucks send power back to the grid during high demand events, so the truck’s role in a home’s energy setup keeps expanding even as individual pieces of it arrive later than promised.
