The Molecular Muscle Experiment will be sending worms into space to study the negative effects of spaceflight on the body, and to help discover therapies to enable long-distance space exploration and treatments for muscle loss. The worms will be flown to the International Space Station, grown for several generations, then analyzed in the lab. The launch is scheduled for a SpaceX mission in November 2018!
