Researchers propose growing construction materials on Mars using a bacterial co-culture to bind regolith for 3D printing.
ISRU concept aims to reduce the need to haul heavy construction materials from Earth to Mars.
Chroococcidiopsis could produce oxygen and support life-support systems on Mars habitats.
Ammonia from Sporosarcina pasteurii could help develop closed-loop agricultural systems on Mars.
The study was published Dec. 2, 2025, in Frontiers, highlighting a potential Mars construction pathway.
Bacteria pair chosen for the technique are Sporosarcina pasteurii and Chroococcidiopsis.
The concept could enable 3D printing of habitat components on the Martian surface.
ISRU-focused research aims to make Mars settlements more sustainable by using local materials.
The approach targets longer-term habitats with potential life-support and terraforming implications.
The article discusses the broader mission context of Mars housing and resource efficiency.

San Francisco to file the nation’s first government lawsuit against UPF makers, naming 10 major food and drink corporations.
The defendants include Coca-Cola, PepsiCo, Kraft Heinz, Post Holdings, Mondelez, and others.
San Francisco alleges UPFs are marketed with deceptive practices that violate state laws and contribute to public nuisance.
California had recently defined UPFs by statute, paving the way for school bans on certain additives.
The case positions public health costs as a key driver for the lawsuit.
Attorneys cited UPFs as linked to a spectrum of diseases and a global health threat.
The filing aligns San Francisco with broader health policy efforts against UPFs.
The suit names major global food companies, targeting widely consumed products.
San Francisco’s attorney highlighted concerns about deceptive marketing to families.
The case follows prior state actions against additives and school food policies.

NIST finds Mars clocks run about 477 microseconds faster per day than Earth clocks, a key finding for future interplanetary timing.
The difference can vary by as much as 226 microseconds daily due to Mars’ orbit and nearby gravitational influences.
Researchers say timing on Mars is essential for synchronizing navigation and communications with Earth and future missions.
The study, published online in The Astronomical Journal, builds on prior work on lunar timekeeping.
The reference point for Mars time estimates was a Martian surface location modeled from mission data.
Timing precision could enable near real-time-like communications across solar-system networks.
Extraneous forces such as the Sun, Earth, and Moon contribute to the timing variability on Mars.
The work aims to support future space missions by improving timekeeping and synchronization.
Clocks on Mars and Earth will diverge by a measurable amount due to relativistic effects.
The Astronomical Journal paper by Neil Ashby and Bijunath R. Patla details the Mars time study.
Timekeeping research on Mars complements ongoing work on lunar and terrestrial clock synchronization.
NIST scientist Bijunath Patla emphasizes the broader goal of expanding solar-system networks.
