In 2025, DLR tested continuous spirulina growth on the ISS for future closed-loop life support; Limnospira indica produced oxygen and edible biomass in microgravity

In a groundbreaking experiment, scientists have successfully cultivated spirulina aboard the International Space Station, paving the way for future Mars exploration. This remarkable blue-green algae can generate oxygen and produce biomass, allowing astronauts to grow food and breathable air independently of Earth. With its high nutritional value and small ecological footprint, spirulina could revolutionize space travel and even enhance disaster relief efforts back on our planet.
