It will undock on July 14, carrying over 580 pounds of cargo, including NASA hardware and experimental data, to conclude the mission. Significant studies conducted by the crew include research on microalgae, a potential resource for food and oxygen in deep-space missions, as well as investigations into the effects of microgravity on vision, cognitive abilities, and cardiovascular health.
