SpaceX to in-house mass production of Starlink internet satellite hardware
SpaceX is rapidly expanding it’s Starlink internet constellation development to prepare for full-scale production and aims to bring nearly every major piece of satellite and network hardware and software in-house, according to details revealed in dozens of job postings.
While not explicit, this appears to indicate a significant convergence of multiple possible paths to an operational constellation. Put simply, SpaceX now intends to build every single major component of its 4400+ satellite network in-house. It’s almost easier to list the things SpaceX does not mean to build themselves, but here’s a stab at the components to be built in-house: satellite structures, laser (optical) data interlinks, on-orbit phased array antennae, digital signal processor (DSPs) software and hardware to aim those antennae, solar arrays, battery systems, power electronics, custom integrated circuitry and systems on a chip (SoCs), user terminals and larger gateways, network operations, production automation, autonomous satellite constellation management, and much, much more.

While entire articles could be spent describing the complexities of every single one of the above subsystems, the point is that SpaceX appears to have gone all-in on building its own satellite constellation, departing from stances in the past that appeared to leave room for subcontracting and outsourcing the production of major parts of the network, particularly with respect to ground terminals and gateways. Postings for ground station and user terminal engineers describe a goal of medium to high volume in-house production of the critical network and customer-facing hardware, and an entry into the production of high volume consumer technology would be a truly eclectic and unprecedented step for a company theoretically focused on launch vehicle development and production and sustainable Mars colonization.
If anything, they speak to the truly vertical nature of SpaceX. Many technology development production companies would simply accede and accept the best subcontractor/outsourcing bid when entering into new territory truly outside of their internal expertise. SpaceX engineers and managers, however, seem to have concluded that the vast majority of hardware and corporate expertise they could co-opt is just not satisfactory for the purpose of building a paradigm-shifting satellite constellation; or as CEO Elon Musk noted in 2015, to “revolutionize the satellite side of things, just as we’ve done with the rocket side of things.”

This new (and, in retrospect, unsurprising) trailblazing attitude also helps to explain the marginal delay to Musk’s original 2015 schedule, which estimated initial constellation operations (i.e. a few hundred satellites launched) would begin around 2020. Approximately a year later, SpaceX had built rough prototypes in the form of the original Microsat 1A and 1B twins. This initial foray into independent, long-term communications smallsats was shuttered fairly quickly, and neither of the demo satellites were launched. Instead, SpaceX dove back into prototype design and development, culminating roughly two years later with the March 2018 launch of two dramatically improved prototypes, known as Tintin A and B (or Microsats 2A and 2B in FCC licenses).
It seems probable that the source of this delay lay in an internal decision to dramatically reconfigure the internet constellation for far more in-house development, whereas the original Microsats were likely pieced together from a range of components derived from SpaceX’s Cargo Dragon program or more simply from commercial off-the-shelf (COTS) offerings. Instead, SpaceX’s Starlink development offices in Redmond, Washington and throughout California are staffed with as many as 400 to 500 employees dedicated in large part to the nascent program, similar (if not larger) in scale to OneWeb, the only noteworthy satellite internet competitor at present.
If SpaceX’s decision to push back Starlink’s operational debut by a few years in order to bring in-house almost every single critical subcomponent of Starlink pays off, the company could begin launching finalized satellites en masse as early as late 2019/early 2020, with a goal of offering limited service by 2021 per comments made by CEO Elon Musk. Starlink is likely being brought almost entirely in-house because Musk or other high-level executives and engineers see major room for improvement, improvements that could lower the cost of and improve the performance of lightweight communications satellites by an order of magnitude.

It will likely take a bit longer than initially expected, but SpaceX may yet still pave their path to Mars colonization with profits derived from a wildly successful and disruptive entrance into the broadband market.

Elon Musk’s TERAFAB project: Everything you need to know
The CEO has hinted heavily for several quarters that it would probably need to produce its own computing power to stay up to speed on the demand it is facing for its projects. It is now taking matters into its own hands.
On Sunday, Elon Musk formally made TERAFAB official—a groundbreaking $20-25 billion joint venture uniting Tesla, SpaceX, and xAI, three of the world’s richest man’s most significant and powerful ventures.
Musk described the project as “the most epic chip building exercise in history by far.”
Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
The initiative aims to produce over one terawatt of AI compute annually, dwarfing the global industry’s current output of roughly 20 gigawatts per year. Musk framed the effort as “the next step towards becoming a galactic civilization,” positioning it as essential for scaling humanity into a multi-planetary species.
The Need for TERAFAB
Existing chip suppliers such as TSMC, Samsung, and Micron cannot expand quickly enough to meet the explosive demand for AI hardware.
We’re building TERAFAB to close the gap between today’s chip production & the future’s demand – a future among the stars.

Musk explained the situation clearly:
“We’re very grateful to our existing supply chain… but there’s a maximum rate at which they’re comfortable expanding. We either build the Terafab or we don’t have the chips, and we need the chips, so we build the Terafab.”
The CEO has hinted heavily for several quarters that it would probably need to produce its own computing power to stay up to speed on the demand it is facing for its projects. It is now taking matters into its own hands.
Chip Types and Production Goals
The facility will manufacture two specialized chip families, according to the presentation:
- Edge-inference AI5 and AI6 processors optimized for Tesla’s Optimus humanoid robots and Full Self-Driving systems in vehicles and Robotaxis
- High-power D3 chips hardened for space environments
Musk outlined annual output targets, which are between 100 and 200 gigawatts of terrestrial compute for robotics, supporting Musk’s vision of producing 1-10 billion Optimus units per year, and the majority (80%) of chips dedicated to orbital AI data centers. Overall, TERAFAB aims to produce 100-200 billion custom AI and memory chips each year.
Scale and Strategy
The size of the TERAFAB project will be remarkable, as Musk indicated after the presentation that the entire Gigafactory Texas campus would not be large enough to fit the needs of the project. In fact, Musk said it would be around 100 million square feet in size, the equivalent of 15 Pentagons or three Central Parks.
Yes, the one in New York City.
Construction will begin with an “advanced technology fab” on the Giga Texas campus in Austin, enabling rapid iteration: design a chip, fabricate lithography masks, produce and test wafers, all within days.
However, the full-scale TERAFAB requires thousands of acres and over 10 gigawatts of power, far exceeding what Giga Texas can accommodate. Musk stated:
“We couldn’t possibly fit the Terafab on the GigaTexas campus. It will be far bigger than everything else combined there.”
Multiple large sites are currently under consideration, but this will need a sprawling land mass to get started.
The sheer scale of TERAFAB is going to be insane.
Elon said it wouldn’t be suitable for anywhere on Giga Texas property because it’s too big:

Key Applications
TERAFAB will be a crucial part of the development of some of Tesla’s most valuable projects, including Optimus and data center development, especially from an orbital standpoint. For that reason, we will break this down into Terrestrial and Orbital applications:
- Terrestrial: Powers autonomous vehicle fleets and billions of Optimus robots performing physical labor
- Orbital: Starship will launch massive AI satellite constellations, starting with 100-kilowatt “Mini” units, and scaling to larger Megawatt models, creating the world’s largest data center in low-Earth orbit.
Space-based advantages include five times greater solar irradiance, efficient vacuum heat rejection, and freedom from terrestrial grid constraints (U.S. electricity generation totals just 0.5 terawatts). Musk emphasized the principle:
“Quantity has a quality all its own.”
We wrote about SpaceX’s recent filing with the FCC for 1 million orbital data center plans.
Strategic Vision
TERAFAB represents vertical integration at an unprecedented scale, combining AI hardware, robotics, and orbital infrastructure.
Musk described the project as “the final missing piece of the puzzle.” With production ramping toward 2027, TERAFAB is set to accelerate an era of abundance, transforming science fiction into reality and positioning Musk’s companies at the forefront of galactic-scale innovation.

Elon Musk offers to pay TSA salaries as government shutdown leaves agents without paychecks
Elon Musk offered to personally cover TSA salaries as the DHS shutdown deepens travel chaos nationwide.
Elon Musk says that he is willing to personally cover the salaries of Transportation Security Administration (TSA) workers caught in the crossfire of a partial government shutdown that has now dragged on for over a month. “I would like to offer to pay the salaries of TSA personnel during this funding impasse that is negatively affecting the lives of so many Americans at airports throughout the country,” Musk wrote.

— Elon Musk (@elonmusk) March 21, 2026
The offer arrives as Congress let funding expire for the Department of Homeland Security on February 14, amid a disagreement over immigration enforcement, leaving most TSA employees classified as essential and on duty but working without pay. The timing could not be more disruptive, as the shutdown is colliding directly with spring break travel season when millions of Americans are in the air.
This is not the first time TSA workers have endured this kind of hardship. TSA agents are being asked to work without pay until congressional action unblocks their paychecks, having previously held out through the longest government shutdown in U.S. history at 43 days. The pattern reveals a systemic failure in how Congress funds critical security infrastructure, and Musk’s offer shines a spotlight on that recurring failure at a moment when the public is directly feeling its effects through long lines and terminal closures.
Whether Musk can legally follow through remains unclear, as federal law generally prohibits government employees from receiving outside compensation related to their official duties.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Tesla, SpaceX, and xAI unveiled TERAFAB, a $25B chip factory targeting one terawatt of AI compute annually.
Elon Musk took the stage over the weekend at the defunct Seaholm Power Plant in Austin, Texas, to officially unveil TERAFAB, a $20-25 billion joint venture between Tesla, SpaceX, and xAI that he described as “the most epic chip building exercise in history by far.” The announcement marks the most ambitious infrastructure bet Musk has made since Gigafactory 1 in Sparks, Nevada, and it fuses three of his companies into a single, vertically integrated AI hardware machine for the first time.
TERAFAB is designed to consolidate every stage of semiconductor production under one roof, including chip design, lithography, fabrication, memory production, advanced packaging, and testing. At full capacity, the facility would scale to roughly 70% of the global output from the current world’s largest semiconductor foundry from Taiwan Semiconductor Manufacturing Company (TSMC).
Elon Musk’s stated goal is one terawatt of computing power annually, split between Tesla’s AI5 inference chips for vehicles and Optimus robots, and D3 chips built specifically for SpaceXAI’s orbital satellite constellation.
Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
The logic behind the merger of these three entities is rooted in a supply chain crisis Musk has been signaling for over a year. At Tesla’s Q4 2025 earnings call, he warned investors that external chip capacity from TSMC, Samsung, and Micron would hit a ceiling within three to four years. “We’re very grateful to our existing supply chain, to Samsung, TSMC, Micron and others,” Musk acknowledged at the Terafab event, “but there’s a maximum rate at which they’re comfortable expanding.” Building in-house was, in his framing, not a strategic option, but a necessity.
The space angle is where the announcement becomes genuinely unprecedented. Musk said 80% of Terafab’s compute output would be directed toward space-based orbital AI satellites, arguing that solar irradiance in space is roughly 5x greater than at Earth’s surface, and that heat rejection in vacuum makes thermal scaling viable. This directly feeds the SpaceXAI vision, which is betting that within two to three years, running AI workloads in orbit will be cheaper than doing so on the ground. The satellites, powered by constant solar energy, would effectively turn low Earth orbit into the world’s largest data center.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Historically, this announcement threads together every major Musk initiative of the past two years: the xAI-SpaceX merger, Tesla’s $2.9 billion solar equipment talks with Chinese suppliers, the 100 GW domestic solar manufacturing push, the Optimus humanoid robot program, and Starship’s development. TERAFAB is the capstone that ties them into a single coherent architecture — chips made on Earth, launched by SpaceX, powered by Tesla solar, run by xAI, and ultimately extended to the Moon.
“I want us to live long enough to see the mass driver on the moon, because that’s going to be incredibly epic,”Musk said during the presentation.
