The NASA Twins Study (Science): A multidimensional analysis of a year-long human spaceflight

Space is the final frontier for understanding how extreme environments affect human physiology. Following twin astronauts, one of which spent a year-long mission on the International Space Station…

To date, 559 humans have been flown into space, but long-duration (>300 days) missions are rare (n = 8 total). Long-duration missions that will take humans to Mars and beyond are planned by public and private entities for the 2020s and 2030s; therefore, comprehensive studies are needed now to assess the impact of long-duration spaceflight on the human body, brain, and overall physiology.

Brown University: NASA Twins Study finds remarkable resilience to the stress of space

A Brown assistant professor studied how the “cellular powerhouse” responds to microgravity stress markers as a part of a NASA study of identical twins.

PROVIDENCE, R.I.[Brown University] — As part of a NASA and Russian Federal Space Agency study on the health effects of long-term space flight, astronaut Scott Kelly spent 340 days on the International Space Station from March 2015 to March 2016 while his identical twin, former astronaut Mark Kelly, remained on Earth.
