In a groundbreaking development, scientists are preparing for fish farming on the moon. This bold initiative aims not only to rear fish in space but also to incorporate them into astronauts’ diets.
Under this innovative plan, researchers are focusing on the technology and resources required for lunar aquaculture. While the concept of taking animals into space is not new, the idea of fish farming is unprecedented.
Originating in 2016, the concept was proposed by Przybyla to the European Space Agency (ESA) but did not receive approval at the time. Now, nearly a decade later, the project, known as Lunar Hatch, has been selected as one of the 100 projects shortlisted for lunar exploration.
Scientists from Southern France are spearheading the initiative, planning to prepare fish eggs on Earth before transporting them to the moon.
The endeavour requires significant preparation, including transporting machinery and equipment to the moon. If successful, this project could make extended space missions more feasible by providing astronauts with a sustainable source of nutrition.
Dr. Cyril Przibil of Ifremer, leading the project, emphasises that fish are rich in protein, omega-3, and various vitamins, which are essential for maintaining astronauts’ health and strength.
One major challenge is sourcing water on the moon. Scientists plan to utilise water ice found on the moon’s polar regions, which are perpetually dark. This ice will be converted into water to fill closed tank systems where the fish will be kept.
The process will mimic Earth-based aquaculture, with fish waste nourishing algae and other species, while shrimps and insects consume the remaining waste, all of which serve as additional food sources for the fish.
If the experiment succeeds, scientists aim to provide fresh fish for a seven-member crew twice a week during a 16-week mission, requiring approximately 200 fish. The primary goal of this programme is to supply astronauts with fresh, nutritious food, thereby enhancing the feasibility of life on the moon.
Additionally, fish farming could positively impact lunar soil and water quality. Special types of fish are being selected to endure the moon’s unique conditions, marking a significant step forward in space exploration and sustainability.
