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.

NASA watchdog says Starship development delays could affect Artemis timeline
The report noted that several technical milestones still need to be completed before Starship can serve as a crewed lunar lander.
A NASA watchdog report stated that continued development work on SpaceX’s Starship could affect the timeline for the agency’s planned Artemis moon missions. The report noted that several technical milestones still need to be completed before the spacecraft can serve as a crewed lunar lander.
The findings were detailed in a report from NASA’s Office of Inspector General, as noted in a report from Reuters.
NASA selected SpaceX’s Starship in 2021 to serve as the Human Landing System (HLS) for its Artemis lunar program. The vehicle is intended to transport astronauts from lunar orbit to the surface of the Moon and back as part of future Artemis missions.
According to the watchdog report, Starship’s development has experienced roughly two years of schedule delays compared to earlier expectations. Still, NASA is targeting 2028 for the first crewed lunar landing using the Starship lander.
One of the most significant technical milestones for Starship’s lunar missions is in-space refueling.
To support a crewed lunar landing, multiple Starship launches will be required to deliver propellant to orbit. Tanker versions of Starship will transfer fuel to a storage depot spacecraft, which will then refuel the lunar lander.
The report noted that this approach could require more than 10 Starship launches to fully refuel the spacecraft needed for a single lunar landing mission.
NASA officials indicated that demonstrating cryogenic propellant transfer in orbit remains one of the most important technical steps before Starship can be certified for lunar missions.
SpaceX has conducted 11 Starship test flights since 2023 as the company continues developing the fully reusable launch system. A 12th test flight, this time featuring Starship V3, is expected to be held in early April.

SpaceX weighs Nasdaq listing as company explores early index entry: report
The company is reportedly seeking early inclusion in the Nasdaq-100 index.
Elon Musk’s SpaceX is reportedly leaning toward listing its shares on the Nasdaq for a potential initial public offering (IPO) that could become the largest in history.
As per a recent report, the company is reportedly seeking early inclusion in the Nasdaq-100 index. The update was reported by Reuters, citing people familiar with the matter.
According to the publication, SpaceX is considering Nasdaq as the venue for its eventual IPO, though the New York Stock Exchange is also competing for the listing. Neither exchange has reportedly been informed of a final decision.
Reuters has previously reported that SpaceX could pursue an IPO as early as June, though the company’s plans could still change.
One of the publication’s sources also suggested that SpaceX is targeting a valuation of about $1.75 trillion for its IPO. At that level, the company would rank among the largest publicly traded firms in the United States by market capitalization.
Nasdaq has proposed a rule change that could accelerate the inclusion of newly listed megacap companies into the Nasdaq-100 index.
Under the proposed “Fast Entry” rule, a newly listed company could qualify for the index in less than a month if its market capitalization ranks among the top 40 companies already included in the Nasdaq-100.
If SpaceX is successful in achieving its target valuation of $1.75 trillion, it would become the sixth-largest company by market value in the United States, at least based on recent share prices.
Newly listed companies typically have to wait up to a year before becoming eligible for major indexes such as the Nasdaq-100 or S&P 500.
Inclusion in a major index can significantly broaden a company’s shareholder base because many institutional investors purchase shares through index-tracking funds.
According to Reuters, Nasdaq’s proposed fast-track rule is partly intended to attract highly valued private companies such as SpaceX, OpenAI, and Anthropic to list on the exchange.

Starbase after dark: Musk’s latest photo captures a Spaceport on the brink of history
SpaceX’s Starbase city in Boca Chica, Texas is rapidly transforming the southern tip of the Lone Star State into one of the most ambitious launch complexes in history.
A striking nighttime photograph of SpaceX’s Starbase facility in Boca Chica, Texas, shared recently by Elon Musk on X, offers a dramatic glimpse of an operation that is rapidly transforming the southern tip of the Lone Star State into one of the most ambitious launch complexes in history.
The most immediately visible change in the photo is the presence of two fully erected Starship launch towers dominating the coastal skyline. The second orbital launch pad, known as Pad B, now features its fully erected tower, OLIT-3, which stands approximately 474 feet tall and incorporates an integrated water-cooled flame trench designed to minimize damage and reduce turnaround time between launches. The dual-tower silhouette against the night sky signals a decisive shift from experimental testing facility to high-cadence launch operations.

Back at Starbase, Pad 2 is approaching hardware completion, with upgraded chopstick arms, a new chilldown vent system, and all 20 hold-down arms now fitted with protective doors to shield them from the intense exhaust of up to 33 Raptor 3 engines, according to a deeper dive by NASASpaceFlight.
SpaceX has also received approval to nearly double the footprint of the Starbase launch site, with groundwork already underway to add LNG liquefaction plants, expanded propellant storage, and additional ground support infrastructure.
The photo also carries a milestone civic dimension. Starbase officially became a Texas city in May 2025 after a community vote, with SpaceX employees elected as mayor and commissioners of the newly incorporated municipality. That legal status streamlines launch approvals and gives SpaceX direct control over local infrastructure decisions.
The FAA has approved an increase in launches from Starbase in Texas from five to twenty-five per year, clearing the runway for the kind of flight frequency needed to fulfill Starship’s ultimate mission of ferrying cargo and crew to the Moon, servicing the Department of Defense, deploying next-generation Starlink satellites, and eventually establishing Elon Musk’s long sought after goal of a self-sustaining human presence on Mars.
Seen from above in the dark, Starbase looks less like a test site and more like a spaceport.
