We are experts working on The Twins Study to learn how NASA spaceflight affects the human body. Ask Us Anything!
UPDATE: Thanks for joining our Reddit AMA about the Twins Study! We're signing off, but invite you to visit www.nasa.gov for more information about findings. Stay curious!
Join a Reddit AMA on Thursday, April 11 at 4 p.m. EDT to ask experts anything about The Twins Study that is helping scientists better understand the impacts of spaceflight on the human body through the study of identical twins. The Twins Study encompassed 10 separate investigators who coordinated and shared all data and analysis as one large, integrated research team. Retired NASA astronaut Scott Kelly spent 340 days in low-Earth orbit aboard the International Space Station while retired NASA 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.
