Under the direction of a mentor, I Investigated protein production via feeding components of Mars' atmosphere and the products of water electrolysis to hydrogen oxidizing bacteria. The aim of this study was to examine ways in which self sustaining colonies can eventually be established on Mars with minimal resources from Earth in order to combat monetary constraints and minimize load during space travel. I later presented my work and findings at the Multidisciplinary Undergraduate Research Conference (MURC).
