SpaceX is in the final stages of preparing a trio of Falcon 9 rockets for a set of launches scheduled less than two days apart.
The potential hat trick will likely be the last opportunity for a salvo of Falcon launches before the end of 2022. As a disclaimer, while unofficial launch dates (derived from regulatory documents or well-sourced public manifests) were consistently close to actual launch dates for most of 2022, that ceased to be the case when SpaceX began experiencing an abrupt uptick in launch delays over the last two months. As a result, Falcon launch dates – even once confirmed by SpaceX – should be assumed to be a bit more uncertain than usual until it’s clear that that trend has died down.
Nonetheless, all available signs indicate that SpaceX and its customers are moving forward with plans for three back-to-back launches before the end of the week.
The update that's rolling out to the fleet makes full use of the front and rear steering travel to minimize turning circle. In this case a reduction of 1.6 feet just over the air— Wes (@wmorrill3) April 16, 2024
Set to kick off the diverse trio is the Surface Water and Ocean Topography (SWOT) spacecraft, a roughly $1.2 billion joint mission between NASA and French space agency CNES. Thanks in part to the COVID pandemic, which has and continues to impact large swaths of NASA and the aerospace industry, NASA’s Jet Propulsion Laboratory completed its portion of SWOT around 9% over budget and eight months behind schedule [PDF] since mission formulation began in 2012. Over a similar time scale, several other NASA missions have experienced cost increases of 10-100%, generally reflecting well on SWOT’s management.
SWOT, a roughly two-ton (~4400 lb) satellite, is designed to conduct the first global survey of all surface water on Earth using two large synthetic aperture radar (SAR) antennas and a conventional radar altimeter. At a cost of roughly $112 million, a SpaceX Falcon 9 rocket is scheduled to launch SWOT to low Earth orbit (LEO) no earlier than (NET) 3:46 am PST (11:46 UTC) on Thursday, December 15th. SpaceX successfully tested SWOT’s Falcon 9 well in advance on December 10th. The rocket was then returned to the company’s hangar at Vandenberg Space Force Base (VSFB) Space Launch Complex 4E for payload installation before rolling back to the pad on December 13th.
The light satellite and low target orbit will allow Falcon 9’s booster to return to the launch site and land at SpaceX’s LZ-4 landing zone, precluding the need for a drone ship recovery.
Up next, another Falcon 9 rocket is scheduled to launch the first two of eleven Boeing-built O3b mPOWER communication satellites for operator SES as early as 4:21 pm EST (21:21 UTC), Friday, December 16th. After lifting off from SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad, Falcon 9 is set to launch the roughly 3.4-ton (~7500 lb) pair of satellites to a medium Earth orbit (MEO) with an altitude of 7825 kilometers (4862 mi).
It’s unclear what orbit Falcon 9 will launch the satellites to, but the rocket’s booster will land on drone ship A Shortfall of Gravitas (ASOG) some 700 kilometers (~435 mi) downrange, indicating that it will need as much performance as the rocket can give. ASOG departed Port Canaveral on December 11th, confirming that launch preparations are well underway.
Finally, a third Falcon 9 rocket could launch SpaceX’s first Starlink mission since October 28th as early as 4:54 or 5:13 pm EST (21:54 or 22:13) on December 16th, potentially just 33 or 52 minutes after O3b mPOWER 1&2. If the two missions do launch on December 16th, which a reliable source of unofficial information has indicated is not guaranteed, it will smash the US record for back-to-back launches of the same rocket family. Russia’s R-7 rocket family will retain the international crown, however, having launched twice in 25 minutes in 1969.
Starlink 4-37 will lift off from SpaceX’s NASA Kennedy Space Center LC-39A pad, and its Falcon 9 booster will attempt to launch on drone ship Just Read The Instructions (JRTI). JRTI departed Port Canaveral on December 12th.
Following Starlink 4-37, SpaceX has at least two more launches tentatively scheduled before the end of 2022. NextSpaceflight.com reports that SpaceX could launch its sixth Transporter rideshare mission from Florida on December 27th, and two Israeli EROS-C3 Earth observation satellites out of California on December 29th. However, it’s worth noting that in the almost 17-year history of SpaceX Falcon operations, the company has never launched a rocket after December 23rd or before January 6th. Transporter-6 and EROS-C3 – SpaceX’s 60th and 61st launches of the year – would have to break through that apparent firewall to launch when they are currently scheduled.

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.
