NASA has conducted several year-long “human research” programmes on the International Space Station, and the resultant data has been interesting. Of these, one of the experiments will test the effect of space on astronaut Scott Kelly’s poop.
During his 342-day-long stay on the orbiting laboratory, Kelly will produce nearly 180 pounds (82kg) of poop. Kelly will also drink 730 litres of recycled urine and sweat during his term aboard the ISS.
“The waste will be discharged at intervals from the space station and will burn up in the Earth’s atmosphere and look like shooting stars,” Nasa said in an infographic release on Monday.
The mission, which also includes Russian cosmonaut Mikhail Kornienko, aims to understand effects of long-term living in space on humans.
Kelly will exercise more than 700 hours during his year-long mission to keep his bones, muscles and heart strong.
