Abstract
Microbes such as algae and bacteria are promising candidates for supporting extended human space travel, as they are robust sources of food, fuel, waste cycling, and oxygen production. Growing microbes on membranes reduces the mass and water demands of a bioreactor system, both of which are important considerations in space travel. The European Modular Cultivation System (EMCS) on the International Space Station (ISS) provides an ideal opportunity to test the effects of microgravity and other aspects of the space environment on algal growth on membranes. This project aims to find optimal growing conditions and measurement technologies that conform to the capabilities of the EMCS. Growth was analyzed through simple RGB image analysis (both increases in area, and changes in color), that could be replicated not only on the EMCS camera system, but ground control experiments conducted in classrooms. This research is important for further refining our knowledge of algae performance in space and bringing space exploration research to the public via the classroom.
