A year is a long time, but it probably flies by while you're zipping 250 miles above Earth, orbiting about 15 times each day.
NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko, both veteran space travelers, launched aboard Soyuz TMA-16M from the Baikonur Cosmodrome in Kazakhstan on March 28, bound for the International Space Station. The pair are scheduled to return to Earth on March 1 on Soyuz TMA-18M.
Part of NASA's Human Research Program, the One-Year Mission on the ISS is a joint effort between the U.S. space agency, the Russian Federal Space Agency (Roscosmos) and international partners. It's part of a research project studying long-term spaceflight and the effects it has on the human body.
Here are 12 awesome things that Kelly and Kornienko experienced during their time orbiting Earth.
