The yeast cell experiment was the first time an organism had its genome edited, the DNA repaired, and then sequenced, all in a spaceflight environment. Future research could build on these methods to better mimic complex DNA damage leading to new ways to protect spacefarers as well as investigations into other long-term space exposure and exploration. Astronauts have successfully performed an experimental gene editing procedure in space for the first time. What is the significance of this experiment ?
