Update #2: SpaceX has successfully delivered Starlink 4-4 – batch of 52 new satellites – to low Earth orbit (LEO), completing the first of three back-to-back Falcon 9 launches scheduled less than three days apart.
Starlink 4-4 marks the 98th successful Falcon landing, the first time SpaceX has performed a non-polar Starlink launch from its West Coast pad, and the first time a Falcon 9 booster has completed 11 orbital-class launches and spaceflights. Up next, SpaceX is scheduled to launch Turkey’s Turksat 5B geostationary communications satellite out of its Cape Canaveral, Florida LC-40 pad. Falcon 9 could lift off as early as 10:58 pm EDT, Saturday, December 18th (03:58 UTC 19 Dec) – just 15 hours after Starlink 4-4. Set in September 2021, SpaceX’s current record is two launches in ~44 hours.
Update: SpaceX’s second dedicated West Coast Starlink launch has slipped to no earlier than (NET) 1:24 am PDT (09:24 UTC) on Saturday, December 18th. Headed to an orbit unusual for a Vandenberg Space Force Base launch, Starlink 4-4 could now lift off just 18 hours before a different SpaceX mission – Turksat 5B – lifts off from the opposite side of the country.
Barring delays to Cargo Dragon’s CRS-24 space station resupply mission, which remains scheduled for 5:06 am EDT on December 21st, that means that SpaceX is now on track to launch three Falcon 9 rockets in three days (less than 73 hours).
SpaceX appears to be on track to round out a record-breaking year with three Falcon 9 launches in four days.
With the diverse trio of missions, SpaceX will orbit another batch of laser-linked Starlink satellites, deliver a large communications satellite to geostationary transfer orbit (GTO), send a Dragon to space for sixth time this year, and break at least two company records. The first mission, known as Starlink 2-3, could occur as early as the morning of December 17th, kicking off an incredibly busy period of launches – and not just for SpaceX.
Starlink 2-3
Referring to the fact that the mission will be the third launch for the second distinct group or ‘shell’ of Starlink satellites, Starlink 2-3 will actually be the second dedicated launch to a semi-polar orbit, leapfrogging Starlink 2-2 for unknown reasons after Starlink 2-1’s successful September launch. Originally scheduled to launch in mid-October, SpaceX was forced to stand down just a few days before liftoff for unknown reasons and at least a week or two of delays soon put Starlink 2-3 at risk of clashing with the company’s upcoming NASA DART launch, which unsurprisingly took precedence. SpaceX successfully launched the Double Asteroid Redirection Test (DART) mission on November 24th.
Late on December 13th, tugboat Scorpius likely departed Port of Long Beach with SpaceX drone ship Of Course I Still Love You (OCISLY) in tow – a fairly airtight confirmation that a SpaceX launch is just a handful of days away. Based on safety Notices to Airmen and Mariners (NOTAMs/NOTMARs), Starlink 2-3 is scheduled to launch sometime between 12am and 6am PDT (UTC-8) on Friday, December 17th. If accurate and SpaceX stays on schedule, Falcon 9 could lift off from the company’s Vandenberg SLC-4E launch pad with Starlink 2-3 in tow just 22 days after a different Falcon 9 rocket launched DART – smashing the pad’s current 36-day turnaround record by almost 40%.
Aside from drastically increasing the maximum theoretical launch cadence SpaceX’s West Coast pad is capable of supporting, Starlink 2-3 is also expected – as it was in October – to fly on Falcon 9 booster B1051, potentially making the mission the first time a liquid rocket booster has completed eleven orbital-class launches. B1051 debuted in March 2019, sending an uncrewed Crew Dragon on its way to orbit for the first time. Before SpaceX’s Starlink launch cadence fell off a cliff in the second half of 2021, B1051 completed its tenth launch on May 9th, 2021, averaging one launch every ~80 days over a two-year career. Starlink 2-3 will be B1051’s first launch in 7 months and eleventh launch in 33 months.
Turksat 5B
As early as 11:58 pm EDT (UTC-5) on Saturday, December 18th, another Falcon 9 rocket is scheduled to launch Turkey’s Turksat 5B geostationary communications satellite from SpaceX’s Cape Canaveral LC-40 pad. There’s a good chance that former Falcon Heavy booster B1052 – recently converted into a Falcon 9 after more than two years in storage – will be assigned to the mission, which is set to be SpaceX’s 30th orbital launch in 2021.
CRS-24 and more!
Finally, a different Falcon 9 (possibly B1062 or even a new booster entirely) is scheduled to launch a new Cargo Dragon 2 spacecraft on CRS-24 – potentially the company’s 23rd operational International Space Station (ISS) resupply run since October 2012. It will be Falcon 9’s sixth Dragon launch of 2021 – another record for SpaceX and the spacecraft. If the schedule holds, CRS-24 could lift off as early as 5:06 am EDT (UTC-5) on Tuesday, December 21st and would be SpaceX’s third Falcon 9 launch in roughly 100 hours (a little over four days). CRS-24 is expected to be SpaceX’s 31st and final launch of 2021, beating out the 26-launch record it set just last year.
However, the rest of the world isn’t quite finished. As early as the day after CRS-24, an Ariane 5 rocket is scheduled to launch the almost $10 billion, NASA-built James Webb Space Telescope (JWST). Decades in the making, JWST will be the single most expensive payload and the largest space telescope ever launched and is functionally irreplaceable and hard (but not impossible, if the political will is there) to repair, making it perhaps the most universally nerve-wracking uncrewed launch in the history of spaceflight.

Elon Musk teases crazy outlook for xAI against its competitors
Musk’s response was vintage hyperbole, designed to rally supporters and dismiss doubters, something his responses on social media often do.
Elon Musk has never been one to shy away from crazy timelines, massive expectations, and outrageous outlooks. However, his recent plans for xAI and where he believes it will end up compared to its competitors are sure to stimulate conversation.
In a bold and characteristic response on X, Elon Musk fired back at a recent analysis that positioned his AI venture, xAI, as lagging behind industry frontrunners.
The post, from March 14, came as a direct reply to forecaster Peter Wildeford’s assessment, which drew from benchmarks and reporting to rank AI developers.
xAI will catch up this year and then exceed them all by such a long distance in 3 years that you will need the James Webb telescope to see who is in second place
— Elon Musk (@elonmusk) March 14, 2026
Wildeford placed Anthropic, Google, and OpenAI in a virtual tie at the top, with xAI and Meta trailing by about seven months. Chinese players like Moonshot, Deepseek, zAI, and Alibaba were estimated to be nine months behind, while France’s Mistral lagged by about a year and a half.
Musk’s response was vintage hyperbole, designed to rally supporters and dismiss doubters, something his responses on social media often do.
He claimed xAI would “catch up this year,” meaning by the end of 2026, erasing that seven-month deficit against the leaders. But he didn’t stop there.
Musk escalated his vision to 2029, predicting xAI would “exceed them all by such a long distance” that observers would need the James Webb Space Telescope, NASA’s orbiting observatory stationed about 930,000 miles from Earth, to spot whoever lands in second place. This analogy underscores Musk’s confidence in xAI’s trajectory, implying an astronomical lead that could redefine the AI landscape.
Breaking down these claims reveals Musk’s strategic optimism. First, the short-term catch-up: xAI, launched in 2023, has already released models like Grok, but recent benchmarks, including those for Grok 4.2, have shown it falling short in capabilities compared to rivals.
Anthropic’s Claude series, Google’s Gemini, and OpenAI’s GPT models dominate in areas like reasoning, coding, and multimodal tasks. Musk’s assertion suggests aggressive scaling in compute, talent, or architecture, perhaps leveraging xAI’s ties to Tesla’s Dojo supercomputers or Musk’s vast resources, to close the gap swiftly.
The longer-term dominance by 2029 paints an even more audacious picture. Musk envisions xAI not just parity but supremacy, outpacing competitors in innovation speed and model sophistication.
This could involve breakthroughs in energy-efficient training, real-world integration, like Tesla’s robotics, or ethical AI alignment, aligning with Musk’s stated goal of “understanding the universe.”
Critics, however, point to parallels with Tesla’s Full Self-Driving delays; one reply highlighted Musk’s 2023 promise of FSD readiness. Musk has made this promise for many years, and although the system has been strong and improving, it is still a ways off from the completely autonomous operation that was expected by now.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
Musk’s comment highlights the intensifying U.S.-centric AI race, with xAI challenging the “three-way” dominance noted by Wharton professor Ethan Mollick, whom Wildeford quoted. As geopolitical tensions rise—evident in the Chinese firms’ lag—Musk’s tease could spur investment and talent wars.
Yet, it also invites scrutiny: Will xAI deliver, or is this another telescope-needed mirage? In an industry where timelines slip but stakes soar, Musk’s words keep the spotlight on xAI’s ambitious path forward.

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.
