STEMonstrations: Digestion

Join ISRO (Indian Space Research Organization) astronaut Shubhanshu Shukla aboard the International Space Station as he demonstrates how our bodies digest food — even in microgravity. Check out the hands-on demonstration of peristalsis, the muscle movement behind digestion, and how this works in space. Learn how the gut microbiome, hydration, and diet play crucial roles in astronaut health while on the International Space Station, as well as in future missions to the Moon and Mars. Explore the corresponding Career Connection and hands-on activity to spark STEM curiosity around engineering, innovation, and careers in space exploration.
