3D-printed Mars habitat could be a perfect fit for early SpaceX Starship colonies
Space architecture startup AI SpaceFactory achieved second place in the latest phase of a NASA-led competition, pitting several groups against each other in pursuit of designing a 3D-printed Mars habitat and physically demonstrating some of the technologies needed to build them.
With a focus on ease of scalable 3D-printing and inhabitants’ quality of life, as well as the use of modular imported goods like windows and airlocks, MARSHA lends itself impeccably well to SpaceX’s goal of developing a sustainable human presence on Mars as quickly, safely, and affordably as possible with the support of its Starship/Super Heavy launch vehicle.
Aside from developing a custom 3D-printing material utilizing in-situ Martian resources and demonstrating the technology by successfully printing a 1200 gallon (4500 L) water tank, SpaceFactory’s habitat design – known as MARSHA – combines a unique level of pragmatism, functionality, and aesthetic elegance. After analyzing different structural options, the SpaceFactory team settled on a cocoon-like cylinder, taking advantage of the many benefits of the Martian environment while controlling for its several downsides. Most notably, Martian gravity is roughly 38% of Earth’s, while the small planet’s atmosphere is typically 80-150 times less dense at surface-level. As a consequence, the forces exerted by Martian winds are minuscule and can effectively be ignored, while the low gravity dramatically minimizes architectural challenges that arise from Earthbound structures having to battle their own weight.
Equally important, all Martian habitats will need to be pressurized to a level comfortable for long-term colonists, requiring that they be able to survive significant internal pressurization. The Martian radiation environment is also significantly less forgiving than Earth, although the dangers of Martian radiation are dramatically overblown. The material of choice SpaceFactory designed to 3D-print its MARSHA habitat – a biorenewable plastic (PLA) reinforced with locally-sourced basalt fiber – also accounts for many of Mars’ shortcomings, as plastics happen to be some of the best materials for radiation shielding per unit of mass. Featuring a duo of PLA shells placing a meter or more of plastic between living areas, MARSHA would permit relatively acceptable radiation levels while avoiding the downsides of locating habitats underground or burying them under several meters of Martian regolith.

Thanks to its cylindrical design and SpaceFactory’s attention to quality of life for astronauts residing within it, MARSHA is also exceptionally beautiful and more than a little alluring even from the perspective of Earthly habitation. MARSHA’s thoughtful design and polished aesthetic would likely mesh well with SpaceX CEO Elon Musk’s own established preferences, known (sometimes infamously so) for a predilection towards building things that value form at least as much as function. Due to the relatively compact nature of the hardware needed (in theory) to begin building MARSHA and the apparent potential for autonomous construction, SpaceFactory’s design also aligns with a number of critical aspects of SpaceX’s outlined Mars colonization architecture.

Up next for NASA’s 3D-printed habitat competition is “Phase 3”, effectively a grand finale: up to eight finalists are expected to compete to 3D-print a 1/3rd scale model of their Mars habitat design as early as May 2019. While not confirmed, it’s likely that SpaceFactory will be among those finalists, potentially helping to offer an early glimpse at what rapidly-printed Mars habitats might look like in real life. SpaceX CEO Elon Musk has also indicated that he would provide a more substantial update on the status of BFR (Starship/Super Heavy) and SpaceX’s Mars architecture soon after the company’s first Starship prototype – unofficially known as Starhopper – begins test flights. That milestone is like no fewer than 1-2 months away.

SpaceX Starship V3 gets launch date update from Elon Musk
The first flight of Starship Version 3 and its new Raptor V3 engines could happen as early as March.
Elon Musk has announced that SpaceX’s next Starship launch, Flight 12, is expected in about six weeks. This suggests that the first flight of Starship Version 3 and its new Raptor V3 engines could happen as early as March.
In a post on X, Elon Musk stated that the next Starship launch is in six weeks. He accompanied his announcement with a photo that seemed to have been taken when Starship’s upper stage was just about to separate from the Super Heavy Booster. Musk did not state whether SpaceX will attempt to catch the Super Heavy Booster during the upcoming flight.
The upcoming flight will mark the debut of Starship V3. The upgraded design includes the new Raptor V3 engine, which is expected to have nearly twice the thrust of the original Raptor 1, at a fraction of the cost and with significantly reduced weight. The Starship V3 platform is also expected to be optimized for manufacturability.
The Starship V3 Flight 12 launch timeline comes as SpaceX pursues an aggressive development cadence for the fully reusable launch system. Previous iterations of Starship have racked up a mixed but notable string of test flights, including multiple integrated flight tests in 2025.
Interestingly enough, SpaceX has teased an aggressive timeframe for Starship V3’s first flight. Way back in late November, SpaceX noted on X that it will be aiming to launch Starship V3’s maiden flight in the first quarter of 2026. This was despite setbacks like a structural anomaly on the first V3 booster during ground testing.
“Starship’s twelfth flight test remains targeted for the first quarter of 2026,” the company wrote in its post on X.

Elon Musk shares insights on SpaceX and Tesla’s potential scale
In a pair of recent posts on X, Musk argued that both companies operate in domains where growth is not linear, but exponential.
Elon Musk outlined why he believes Tesla and SpaceX ultimately dwarf their competitors, pointing to autonomy, robotics, and space-based energy as forces that fundamentally reshape economic scale.
In a pair of recent posts on X, Musk argued that both companies operate in domains where growth is not linear, but exponential.
Space-based energy
In a response to a user on X who observed that SpaceX has a larger valuation than all six US defense companies combined, Musk explained that space-based industries will eventually surpass the total economic value of Earth. He noted that space allows humanity to harness roughly 100,000 times more energy than Earth currently uses, while still consuming less than a millionth of the Sun’s total energy output.
That level of available energy should enable the emergence and development of industries that are simply not possible within Earth’s physical and environmental constraints. Continuous solar exposure in space, as per Musk’s comment, removes limitations imposed by atmosphere, weather, and land availability.
Autonomy and robots
In a follow-up post, Elon Musk explaned that “due to autonomy, Tesla is worth more than the rest of the auto industry.” Musk added that this assessment does not yet account for Optimus, Tesla’s humanoid robot. As per the CEO, once Optimus reaches scaled production, it could increase Earth’s gross domestic product by an order of magnitude, ultimately paving the way for sustainable abundance.
Even before the advent of Optimus, however, Tesla’s autonomous driving system already gives vehicles the option to become revenue-generating assets through services like the Tesla Robotaxi network. Tesla’s autonomous efforts seem to be on the verge of paying off, as services like the Robotaxi network have already been launched in its initial stages in Austin and the Bay Area.

Tesla CEO Elon Musk trolls budget airline after it refuses Starlink on its planes
“I really want to put a Ryan in charge of Ryan Air. It is your destiny,” Musk said.
Tesla CEO Elon Musk trolled budget airline Ryanair on his social media platform X this week following the company’s refusal to adopt Starlink internet on its planes.
Earlier this week, it was reported that Ryanair did not plan to install Starlink internet services on its planes due to its budgetary nature and short flight spans, which are commonly only an hour or so in total duration.
Initially, Musk said installing Starlink on the company’s planes would not impact cost or aerodynamics, but Ryanair responded on its X account, which is comical in nature, by stating that a propaganda it would not fall for was “Wi-Fi on planes.”
Musk responded by asking, “How much would it cost to buy you?” Then followed up with the idea of buying the company and replacing the CEO with someone named Ryan:
I really want to put a Ryan in charge of Ryan Air. It is your destiny.
— Elon Musk (@elonmusk) January 19, 2026
Polymarket now states that there is an 8 percent chance that Musk will purchase Ryanair, which would cost Musk roughly $36 billion, based on recent financial data of the public company.
Although the banter has certainly crossed a line, it does not seem as if there is any true reason to believe Musk would purchase the airline. More than anything, it seems like an exercise of who will go further.
Starlink passes 9 million active customers just weeks after hitting 8 million
However, it is worth noting that if something is important enough, Musk will get involved. He bought Twitter a few years ago and then turned it into X, but that issue was much larger than simple banter with a company that does not want to utilize one of the CEO’s products.
The insufferable, special needs chimp currently running Ryan Air is an accountant. Has no idea how airplanes even fly.
— Elon Musk (@elonmusk) January 20, 2026
In a poll posted yesterday by Musk, asking whether he should buy Ryanair and “restore Ryan as their rightful ruler.” 76.5 percent of respondents said he should, but others believe that the whole idea is just playful dialogue for now.
But it is not ideal to count Musk out, especially if things continue to move in the direction they have been.
