SpaceX’s first Falcon Heavy launch in three years eyes late-October liftoff
For the second time in 2022, SpaceX’s Falcon Heavy rocket has a firm launch date for the first time in more than three years.
Cursed by a seemingly relentless flood of delays impacting almost every one of the rocket’s payloads, Falcon Heavy made it within three or four months of ending its launch drought as recently as June 2022. At the time, the rocket was more or less ready to begin assembly, but NASA announced late that month that the Jet Propulsion Laboratory (JPL) and supplier Maxar had failed to finish qualifying software needed to power its Psyche spacecraft. Designed to journey to and enter orbit around the asteroid 16 Psyche, the complex trajectory required to reach it constrained the mission to a launch window sometime between August and October.
When JPL and Maxar were unable to properly test the spacecraft’s software in time for that window, they were forced to stand down and wait until the next earliest window, which begins in July 2023. That left Falcon Heavy with three more possible payloads to launch in 2022, but all three were chronically delayed and there was little reason to believe that even one of them would be ready to launch before 2023. However, Falcon Heavy’s single most delayed payload appears to have made a breakthrough, giving the most powerful rocket currently in operation at least one more shot at a 2022 launch.
Continuing an excellent series of reports tracking Falcon Heavy’s never-ending US military payload delays, Spaceflight Now broke the news with an official statement from the US Space Force, which confirmed that an unspecified industry partner had finally resolved payload problems that have delayed the military’s USSF-44 mission by two years. More importantly, the USSF spokesperson revealed a specific target of October 28th.
The US military has repeatedly offered implausible launch targets for USSF-44 with little to no official explanation for the mission’s delays, making it reasonable to appraise any specific launch date much like a boy crying wolf. But this particular target, announced within the same month as its date, is a bit more believable on its own.
Thankfully, it’s not on its own. On October 7th, SpaceX sent out an email confirming that Falcon Heavy is scheduled to launch USSF-44 sometime in October and asking members of the media to register for press site access and remote camera setup opportunities. It’s possible that the rocket or USSF-44 satellites will run into issues and trigger additional delays, but a press accreditation email is about as close as one can get to a believable guarantee that a secretive US military payload is on track for a SpaceX launch scheduled more than a week or so in the future.
The mission’s next major step forward will be the assembly of Falcon Heavy inside SpaceX’s main hangar at its NASA Kennedy Space Center LC-39A pad. Photos SpaceX shared last month and earlier this month of preparations for Crew-5, Falcon 9’s eighth successful astronaut launch, show that at least two of the four main stages that make up Falcon Heavy are already inside that hangar. One of two new Falcon Heavy side boosters was clearly spotted on September 30th.
The rocket’s expendable upper stage was also clearly visible in a September 23rd photo. Ordinarily, Falcon upper stages are nearly indistinguishable from each other, but the upper stage stored behind the Crew-5 upper stage in the foreground features a unique grey band around the bottom of its airframe. In July 2019, SpaceX tested another Falcon 9 upper stage with the same grey band, which a spokesperson explained was meant to improve the rocket’s longevity in orbit.
Long orbital coasts of six or more hours are necessary for some of the most challenging launch trajectories. Direct-to-geostationary launches are the most common type of mission to require long coast capabilities and are often demanded by the US military. The grey band’s purpose is to increase the amount of heating absorbed from sunlight to warm the liquid kerosene (RP-1) fuel contained within that part of the rocket. When it gets too cold, kerosene – which freezes at a much higher temperature than Falcon’s liquid oxygen oxidizer – becomes viscous and slush-like before it freezes solid. If ingested, slushy fuel would likely prevent ignition or destroy the upper stage’s Merlin engine.
USSF-44 will be SpaceX’s first direct geostationary launch attempt, explaining why the grey band has reappeared more than three years after its first test. Coincidentally, Falcon Heavy’s third and latest launch occurred in June 2019, just one month before that upper stage test. 40 months later, the rocket might finally launch again, and it will do so by attempting what is likely SpaceX’s most difficult customer mission to date. To enable the high performance required for the mission, USSF-44 will also intentionally expend a Falcon Heavy booster for the first time. The rocket’s two new side boosters will boost back to Florida and land side by side at LZ-1 and LZ-2, but its new center core will be expended after a single flight.
SpaceX has already finished converting Pad 39A’s mobile transporter/erector, which was previously set up for single-core Falcon 9 rockets. The T/E will eventually roll inside the pad’s integration hangar, confirming that Falcon Heavy has been fully assembled and is about to be installed on the structure. The rocket will then be rolled out to the pad and brought vertical for static fire testing, a process that will likely begin at least a week before the current October 28th launch target.
If testing is successful, Falcon Heavy will return to the hangar, have its fairing and USSF-44 payload installed, and roll out to the pad one last time. Stay tuned for updates on that ongoing process.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Tesla set to launch “Terafab Project: A vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla is making one of the boldest bets in its history. On March 14, Elon Musk posted on X that the “Terafab Project launches in 7 days,” pointing to March 21, 2026 as the start date for what he has described as a vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla first confirmed Terafab on its January 28, 2026 earnings call, where Musk told investors the company needs to build a chip fabrication facility to avoid a supply constraint projected to materialize within three to four years. But the seeds were planted even earlier. At Tesla’s annual general meeting last year, Musk warned that even in the best-case scenario for chip production from their suppliers, it still wouldn’t be enough, and declared that building a “gigantic chip fab” simply had to be done.
While there has been no official announcement on where Tesla plans to break ground on the massive Terafab, all signs point to the North Campus of Giga Texas in Austin.
Months of speculation has surrounded Tesla’s North Campus expansion at Giga Texas, where drone footage captured by observer Joe Tegtmeyer revealed massive construction site preparation just north of the existing factory on a scale that rivals the original Giga Texas footprint itself.
Samsung’s Tesla AI5/AI6 chip factory to start key equipment tests in March: report
The project is projected to produce 100–200 billion AI and memory chips annually, targeting 100,000 wafer starts per month, at an estimated cost of $20 billion. Tesla is targeting 2-nanometre process technology and anticipated to be the most advanced node currently in commercial production. Dubbed the Tesla AI5 chip, the chip will pack 40x–50x more compute performance and 9x more memory than AI4, and will be among the first products Terafab factory is set to produce. This highly optimized, and massively powerful inference chip is designed to make full self-driving (FSD) and Tesla’s Optimus robots faster, safer, and with full autonomy.

This is where Terafab becomes a genuine game-changer. If Tesla successfully builds a 2nm chip fab at scale, it becomes one of only a handful of entities that’s capable of producing AI silicon in-house, with competitive implications that extend far beyond Tesla’s own vehicles, and potentially positioning Tesla as a chip supplier or licensor to other industries.

The next-gen Tesla AI chips will power advancements in Full Self-Driving software, the Cybercab Robotaxi program, and the Optimus humanoid robot line. Musk’s projections for Optimus require chip volumes that no existing external supplier can commit to on Tesla’s timeline.Competitors like Waymo and GM’s Cruise remain dependent on third-party silicon, leaving them exposed to the same supply chain vulnerabilities Tesla is now working to eliminate entirely.
The Terafab launch this week may not mean a factory opens its doors overnight, but it signals Tesla is serious about owning the entire AI stack, from software to silicon.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…
— Elon Musk (@elonmusk) March 11, 2026
Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.
— Elon Musk (@elonmusk) March 12, 2026
Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.
