The NASA twins study

Domingo, 21 de abril de 2019 Google Scholar Sin comentarios

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 for the2020s and 2030s; therefore, comprehensive studies are needed. The selection of one of a pair of monozygotic (identical) twin astronauts for NASA’s first 1-year mission has enabled  to compare the impact of the spaceflight environment on one twin to the simultaneous impact of the Earth environment on a genetically matched subject.

The conclusion is as following: “Given that the majority of the biological and human health variables remained stable, or returned to baseline, after a 340-day space mission, these data suggest that human health can be mostly sustained over this duration of spacefligh”
