The Effects of Microgravity on Microbial Nitrogen Fixation (Microbial Nitrogen Fixation) explores the effectiveness of two strains of nitrogen-fixing bacteria. Nitrogen is an essential element in plant growth, but plants use only reduced forms of nitrogen and much of it is produced by these bacteria. Determining whether and how nitrogen fixation occurs in space is key to successfully growing plants on future missions.
