NASA HRP Twins Research Study with Craig Kundrot

On March 7, NASA announced the selection of 10 investigations for the study of identical twin astronauts Scott and Mark Kelly and, in doing so, launched human space life science research into a new era. Although NASA's Human Research Program has been researching the effects of spaceflight on the human body for decades, these 10 investigations will provide NASA with broader insight into the subtle effects and changes that may occur in spaceflight as compared to Earth-based environments.
