To mark the halfway point of the organization's "Year in Space" mission, NASA released some incredible facts and figures about what American astronaut Scott Kelly is going through during his 342 days aboard the International Space Station (ISS).

The mission, which also includes Russian cosmonaut Mikhail Kornienko, aims to better understand what long-term effects living in space has on the human body. Topics for research in this mission span a variety of topics, including whether human functionality dips over that period of time, neurological effects of 12 months in space, and if there are any physical detriments (ocular, metabolic, or otherwise). NASA provides background and updates on the mission at http://www.nasa.gov/1ym. The "Year in Space" mission is running in tandem with the notable "Twins Study," where Kelly's brother Mark remains on Earth and is examined in similar ways to Scott.

Within NASA's infographic on Scott Kelly's half of year in the stars, there are a number of eye-catching statistics. The organization reports that over the course of the mission, Kelly will "produce about 180 pounds of feces that will burn up in the atmosphere and look like shooting stars. Your feces will not be shooting stars." NASA also notes that he will drink 730 liters of recycled urine and sweat during his year aboard the ISS—we're guessing that the figures will hold essentially the same for Kornienko.

Despite length being a primary factor in this study, Kelly and Kornienko will not be setting any records for the longest time in space. That distinction is held by Russian cosmonaut Valeri Polyakov, who was aboard the Mir space station in 1994 and 1995 for 437 days.
