Space-grown mushrooms test future nutrition for deep-space missions

Researchers grew edible fungi (lion’s mane, turkey’s tail, cordyceps) as mycelium aboard the ISS in 2024 to explore space nutrition for long missions. After returning to Earth, the samples were cultivated into mushrooms on Earth, eaten in recipes, and shown to continue producing harvests in various environments, suggesting microgravity doesn’t hinder their growth and hinting at space-provisioned food for future expeditions like Artemis II.

Microgravity reshapes the bacteria–phage battle aboard the ISS

A study on the ISS shows that microgravity alters how bacteria and their phages interact: E. coli and phage T7 infect more slowly without convection, leading to distinct mutations in both organisms; space-evolved phages become better at binding and, when tested back on Earth, are more effective against certain UTI-causing E. coli—highlighting potential for phage therapies and astronaut health research, albeit with cost barriers to replicating microgravity experiments.

NASA Astronaut Kate Rubins, DNA Sequencing Pioneer in Space, Retires

NASA astronaut Kate Rubins retired after 16 years, during which she completed two missions on the International Space Station, becoming the first person to sequence DNA in space and contributing significantly to space biology and biomedical research. She also played a key role in developing space suits for future Artemis missions and continues to advocate for innovation at the intersection of biology and space. Her career leaves a lasting legacy in space exploration and scientific advancement.

"Mutation of Multi-Drug Resistant Bacteria on ISS Driven by Space Environment"

NASA-funded research reveals that multi-drug resistant strains of the bacterium Enterobacter bugandensis, isolated from the International Space Station (ISS), have mutated to become genetically and functionally distinct from their Earth counterparts, persisting and coexisting with other microorganisms in the extreme environment of the ISS. This study sheds light on microbial dynamics in closed human-built environments, providing insights for effective preventative measures for astronaut health in space.
