NASA has recently announced the findings of “Twins
Study”. The study has been published in the journal Science.
The NASA’s Twin Study is a comprehensive review
of the response of the human body to spaceflight. The study was conducted on
two identical twins, one of whom spent one year in low-Earth orbit aboard the
International Space Station while the other remained on earth. The study was
conducted from 2015-2016.
The Twins Study has demonstrated the resilience
and robustness of how a human body can adapt to a multitude of changes induced
by the spaceflight environment. It has revealed that long-term space missions
are likely to cause major changes to astronauts’ metabolisms, genetics and
The Twin Study is a significant step and will
help guide future biomedical space research. Further, it could also provide important
insights for NASA’s 2020 mission to Mars, a mission that is expected to last
two to three years.
