SpaceX to submit Moon lander proposal for latest NASA spaceflight competition
SpaceX reportedly plans to submit its own human-rated Moon lander design for NASA’s latest major request for proposal (RFP), part of the agency’s rough plan to return humans to the Moon no earlier than 2028.
Meant to begin delivering NASA astronauts to the surface of the Moon as early as 2028, the agency hopes to base those lander operations on a thus far unbuilt space station orbiting the Moon with the support of its SLS rocket and Orion spacecraft.
This is actually a pretty big deal. https://t.co/P6LXAMXVJI

SpaceX will submit a lunar lander design.

Meant to build directly off of SLS/Orion, a NASA-designed rocket and spacecraft beset with at least three years of delays and billions of dollars in cost overruns, it’s unclear where SpaceX might fit into NASA’s latest modernized attempt at an Apollo Program 2.0. Alongside the 2017 cancellation of Crew Dragon’s propulsive landing program due in part to the likely cost of the certification burden NASA would have placed on the technology before allowing it to land astronauts, SpaceX also canceled Red Dragon (and thus Grey Dragon), a proposal to use a minimally modified version of Crew Dragon as an ad-hoc Mars lander and R&D testbed.
Aside from the likely cost of certifying propulsive Crew Dragon to NASA specifications, CEO Elon Musk also explained the program’s cancellation as a consequence of SpaceX’s far greater interest in what he described as “vastly bigger ship[s]” in July 2017. This translated into a presentation at IAC 2017 a few months later, where Musk revealed SpaceX’s updated design for a giant, fully-reusable launch vehicle meant to enable sustainable Mars colonization, known then as BFR. BFR has since been reconceptualized at least two more times, settling (at present) on a radical new approach said to rely heavily on stainless steel as a replacement for advanced carbon composites.
Initially making one 200 metric ton thrust engine common across ship & booster to reach the moon as fast as possible. Next versions will split to vacuum-optimized (380+ sec Isp) & sea-level thrust optimized (~250 ton).

In the second half of 2018 and the first few months of 2019, the SpaceX CEO’s BFR (now Starship/Super Heavy) narrative has noticeably diverged from a largely exclusive focus on Mars to include a new interest (be it genuine or out of convenience) in the Moon. Most notably, Musk stated in January and February 2019 that SpaceX’s single-minded goal for BFR was now “to reach the moon as fast as possible”. In response to a question about SpaceX’s intentions for the first few orbital BFR (Starship) launches, Musk also replied, “Moon first, Mars as soon as the planets align”.
This is likely explicitly connected to Japanese billionaire Yusaku Maezawa’s decision to purchase the first operational Starship (BFR) launch in support of his philanthropic #DearMoon project, meant to send 8-10 artists from across Earth on the first commercial voyage around the Moon as early as 2023. While no specific value was given, the implication of CEO Elon Musk’s emotional response when discussing the financial support pegged the number in the hundreds of millions of dollars, likely on the order of $250M to $500M. However, any astute bureaucrat or aerospace executive would also be (and have been) distinctly aware of a new political undercurrent pushing for the US and NASA to return humans to the Moon, circulating for the last few years before breaking through to the surface in the last six or so months.

Orion/SLS versus Starship/Super Heavy?
Per Musk’s frequent and insistent comments on just how hard he expects it to be for SpaceX to fully fund the development of BFR, it would come as no surprise to learn that SpaceX had set its eyes on potential sources of major BFR development funds. Where exactly NASA will find the multibillion-dollar sum likely required to develop even a commercial human-rated Moon lander is entirely unclear, but alas. Although NASA’s new Moon mission seems like an apt fit for SpaceX, funding aside, the problem remains that SpaceX’s next-generation Starship/Super Heavy (formerly BFR) launch vehicle poses a direct, existential threat to NASA’s SLS rocket and Orion spacecraft, an almost entirely expendable system likely to cost no less than $1B per launch and unlikely to launch for the first time until 2021.
NASA’s human return to the Moon is meant to directly complement SLS/Orion thanks to the intention of using a theoretical Moon-based space station (known as Gateway) in a bizarre lunar orbit (known as a “Near Rectilinear Halo Orbit” or NRHO) as the base of lunar-landing operations. The decision to place said Gateway in a lunar halo orbit derives almost exclusively derives (PDF) from a separate decision to design NASA’s future exploration plans around SLS and Orion, particularly Orion in the context of the Moon. Put simply, Orion is relatively mass-inefficient and has a fairly limited amount of delta V (shorthand for the capacity to change one’s velocity), preventing far more useful orbits (i.e. actual lunar orbits). The fragile web of Gateway, SLS, Orion, and any potential crewed Moon landers is intentionally designed to be interdependent, meaning that each piece on its own makes little objective sense and has no obvious functional benefit relative to a bevy of alternatives.

As designed, SpaceX’s Starship/Super Heavy combo would be a nearly redundant and radically simpler solution to the mishmash of Gateway, SLS, Orion, and others. A return to using propulsive Crew Dragon landings as a method of significant payload delivery to the lunar surface is immensely unlikely. The value of an entirely new SpaceX-built craft is equally unclear, given Musk and SpaceX’s general stance on putting development funds towards things that bring the company closer to achieving its ultimate goal of sustainable interplanetary colonization. Regardless, it will undoubtedly be exciting to see what happens and whether SpaceX actually chooses to submit a proposal for one or all aspects of NASA’s baselined lunar lander.

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.

— SpaceX (@SpaceX) March 22, 2026
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 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.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket
Space Force drops ULA for SpaceX on GPS launch after Vulcan rocket anomaly investigation halts flights.
The U.S. Space Force announced today it is switching an upcoming GPS III satellite launch from United Launch Alliance’s Vulcan rocket to a SpaceX Falcon 9, a move that is as much a reflection of Vulcan’s mounting problems as it is a validation of SpaceX’s growing dominance in national security space launch. The GPS III Space Vehicle 09, originally contracted to fly on Vulcan this month, will now target a late April liftoff on Falcon 9, marking the fourth consecutive GPS III satellite the Space Force has moved to SpaceX after contracts were originally awarded to ULA.
The immediate trigger is a solid rocket motor anomaly that occurred on February 12 during Vulcan’s USSF-87 mission. Although the payloads reached orbit and ULA declared the mission successful, the company characterized the malfunction as a “significant performance anomaly” and has since paused all military launches on Vulcan pending a root cause investigation.
“With this change, we are answering the call for rapid delivery of advanced GPS capability while the Vulcan anomaly investigation continues,” said Systems Delta 81 Commander Col. Ryan Hiserote. “We are once again demonstrating our team’s flexibility and are fully committed to leverage all options available for responsive and reliable launch for the Nation.”
The broader reality is that SpaceX’s reliability record and launch cadence have made it the path of least resistance for the Pentagon, and bodes well with Elon Musk’s plans to IPO SpaceX sometime this year. Its Falcon 9 is the most flight-proven rocket in history, and the Space Force’s Rapid Response Trailblazer program was specifically designed to enable exactly this kind of provider swap for GPS missions, and effectively building SpaceX’s flexibility into the national security launch architecture by design.
For ULA, the stakes are existential. The company entered 2026 with aspirations of finally turning a corner after years of Vulcan delays, with interim CEO John Elbon pointing to a backlog of over 80 missions as reason for optimism. Meanwhile, SpaceX’s contracts with the Space Force have given it a formal pathway to take on even more national security launches going forward.
The significance of today’s announcement extends beyond one satellite swap. It reinforces that America’s most critical space infrastructure, including GPS, missile warning, and beyond, is increasingly dependent on a single commercial provider.
