The Effects of Long-Duration Space Travel on the Human Body
TLDR NASA astronaut Scott Kelly spent a year in space to study the effects of long-duration space travel on the human body. Living in space can be challenging, causing changes in gene expression and potential health implications, but NASA continues to study and prepare for future missions to Mars.
Timestamped Summary
00:00
Scott Kelly spent 340 days in space while scientists analyzed the effects on his body, comparing him to his identical twin brother Mark who stayed on Earth.
04:38
NASA astronaut Scott Kelly spent a year on the International Space Station to study the effects of long-duration space travel on the human body, with the goal of preparing for future missions to Mars.
08:33
Scott Kelly spent a year in space and observed that while there were some incredible views, living in an enclosed environment without weather or the ability to go outside can be challenging, especially when something happens back home and you can't be with your family.
12:16
Living in space for an extended period of time can cause fluid to collect in weird places in the body, potentially affecting eyesight, and while Scott Kelly's DNA did not change during his time in space, the interpretation of his DNA did.
16:01
Living in space for an extended period of time can cause changes in gene expression in areas such as bones and the immune system that can persist for at least six months after returning to Earth, but the long-term health implications are still unknown.
19:47
Scott Kelly's year in space comes to an end, and while NASA continues to study the effects of space on the body, they acknowledge that a team effort will be necessary for future missions to Mars.
24:20
NASA conducts space simulations on Earth, including one in Utah where people pretend to live on Mars, and another in Hawaii where a crew lives in a dome for a year to simulate the conditions of a Mars mission.
28:01
Scientists are conducting various experiments, such as sending people to live in a dome in Hawaii, to understand the physical and mental effects of long-duration space travel on humans before we go to Mars.
