Among its other functions, the International Space Station is a scientific laboratory. During a typical 6-month period, about 800 researchers from around the globe run 250 to 300 experiments onboard the ISS.
One recent experiment broke the mold. One researcher, Scott Smith, was able to publish the data from a genetic analysis of ISS astronauts.
"This analysis is really the first use of genetic data onboard the space station," Station Deputy Chief Scientist Kirt Costello said.
Analyzing astronaut DNA could be the key to fixing some health problems that occur because of the micro-gravity environment, like bone loss and vision problems. Solving these health problems is key for future manned space missions.
