Indian Space Research Organisation (ISRO) astronaut and Group Captain Shubhanshu Shukla, currently aboard the International Space Station (ISS) as part of the Axiom Mission 4 (Ax-4), conducted a series of scientific experiments on Monday focused on muscle health, digestion in space, and astronaut mental well-being.

According to NASA, Shukla worked inside the Kibo laboratory's Life Sciences Glovebox to study how muscle stem cells behave in microgravity. He also recorded an educational video for Indian school students explaining how the human digestive system adapts in space.

NASA said, "Indian astronaut Shubhanshu Shukla filmed a video targeted to young Indian students discussing how the digestion system adapts to space. Next, Shukla worked in Kibo's Life Science Glovebox checking muscle stem cell cultures to learn how to maintain muscle health in space."
