Researchers at the University of Naples Federico II tested aquarium moss that could sustain astronauts on future missions to Mars [1].
This discovery is significant because long-term space missions require compact, resilient biological systems to manage air and water without relying solely on Earth-based supplies.
Supported by the European Space Agency, the research team focused on the plant's ability to perform multiple life-support functions simultaneously [1]. The moss demonstrated the capacity to filter water and produce oxygen, which are critical requirements for any habitable Martian colony.
One of the most notable findings involves the plant's reaction to radiation. The researchers said the moss grew stronger when exposed to low doses of radiation [1]. This trait is particularly valuable for space travel, where cosmic radiation poses a constant threat to biological organisms and human health.
By utilizing these biological systems, space agencies could potentially reduce the mass of mechanical equipment needed for life support. The moss serves as a natural filtration and oxygenation system, a biological tool that adapts to the harsh conditions of deep space [1].
The experiment took place at the University of Naples Federico II laboratory [1]. The findings suggest that common aquatic plants may hold the key to creating sustainable ecosystems on other planets.
“The moss demonstrated the capacity to filter water and produce oxygen.”
The ability of a biological organism to thrive under radiation—rather than succumb to it—shifts the strategy for Martian colonization from mere protection to active integration. If plants can utilize the environment's natural stressors to grow stronger, the reliance on heavy, energy-intensive shielding and mechanical scrubbers may decrease, making long-term habitation more feasible.
