Agnirva Space Premier League - Expedition #31811: Chlorella in Orbit: Can This Green Algae Support Life in Space?

Sustaining life in space requires more than just food and water—it also demands efficient oxygen generation. The experiment titled 'The Effects of Microgravity on Oxygen Output Regarding Chlorella vulgaris' explores whether a species of green algae could help meet this need.

Chlorella vulgaris is known for its oxygen-producing and carbon-dioxide-consuming capabilities. This study tested how microgravity affects these functions. Scientists wanted to know: Would the algae’s photosynthetic efficiency change in orbit? Could it be part of future life support systems?

Early results indicate that while microgravity alters some aspects of algal growth, the core photosynthetic processes remain viable. This is promising for closed-loop environmental systems on the ISS and future space habitats. The research also fosters educational opportunities, as it was conducted by student-led teams through Higher Orbits.
