Agnirva Space Premier League - Expedition #31645: Fueling the Future from Space: Chatfield High Explores Algae-Based Biofuels in Microgravity

Can algae produce fuel in space? That’s the question that inspired students at Chatfield High School to design an experiment on the International Space Station. Their project examined how microgravity affects two strains of biofuel-producing algae, with the goal of understanding whether space farming could someday power human missions beyond Earth.

Algae are known for their ability to produce lipids, which can be converted into biofuels. The team selected two strains commonly studied on Earth for renewable energy applications. In microgravity, however, the behavior of cells can change drastically. Growth rates, lipid production, and even cellular structure can be altered.

The student-designed experiment was launched during Expedition 43/44. The setup included biocontainment units to safely house and grow the algae in space. Once the samples returned to Earth, students analyzed them for biomass accumulation and lipid yield.

Initial results showed that while growth rates were slower, certain metabolic pathways were enhanced in microgravity. This suggests that with some optimization, space-grown algae could indeed become a part of the biofuel supply chain for space missions.

This project not only highlighted a sustainable energy alternative but also emphasized student empowerment through real scientific inquiry. It demonstrated the feasibility of integrating education, space research, and environmental consciousness.
