Space Records, Health Studies, and Post-NASA Work
Year-Long Mission and Twin Study
Kelly holds the record for the longest single spaceflight by an American astronaut at 340 days aboard the ISS during Expeditions 43/44/45/46 from March 2015 to March 2016. He participated in the NASA Twins Study alongside his identical twin brother, astronaut Mark Kelly, to measure the effects of long-duration spaceflight on the human body. The study examined changes in gene expression, bone density, muscle mass, vision, and cognitive performance, with results published in peer-reviewed journals and reported by major outlets.
After retiring, Kelly has focused on writing, public speaking, and consulting in the aerospace and technology space. He authored multiple books, including "Endurance" and "My Journey to the Stars," which detail his experiences in space and the physical and psychological demands of long-duration missions. Kelly has also served as a strategic advisor and public advocate for STEM education, space exploration, and science communication, engaging with institutions and companies involved in next-generation spaceflight and research.
