A study aiming to investigate the effects of spaceflight on the human organism. The study was organized by NASA with the support of 8 universities across the USA. It was conducted in 2015-2016 and involved two identical twin brothers: Scott and Mark
Kelly.
Scott Kelly
served on a year-long mission aboard the International Space Station, while
his brother Mark Kelly, a former NASA employee, remained on Earth. The twins study
included an array of biochemical, neurological and other types of medical tests
conducted before, during and after the spaceflight, i.e. over the span of 27 months. The results confirmed the
robustness and resilience of human health, since 91,3% of Scott Kelly’s medical
parameters returned to baseline six months after the spaceflight. The remaining
changes were to be used for development of personalized measures to predict and
overcome possible adverse consequences of spaceflight.
