The Twins Study is helping scientists better understand the impacts of spaceflight on the human body through the study of identical twins. The Twins Study research encompassed 10 separate investigators who coordinated and shared all data and analysis as one large, integrated research team. Retired astronaut Scott Kelly spent 340 days in low-Earth orbit aboard the International Space Station while retired astronaut Mark Kelly, his identical twin, remained on Earth. The twins’ genetic similarity provided scientists with a reduced number of variables and an ideal control group, both important to scientific investigation.
