Microalgae and Life Support in Space

The video discusses the necessity of resources like oxygen and food for astronauts in space. It introduces the Photobioreactor experiment on the ISS, which aims to create a hybrid life-support system by combining biological and physical-chemical processes. Microalgae, specifically Chlorella vulgaris, play a crucial role by converting carbon dioxide into oxygen and producing edible biomass. The experiment also explores the potential benefits of microalgae for Earth applications, such as air treatment and food production. This research is vital for future space exploration and self-sustaining life-support systems.
