American astronaut Scott Kelly is back on Earth, ending his extended stay on the International Space Station. Kelly and cosmonaut Mikhail Kornienko, who both spent most of the past year in space, landed at 11:26 p.m. ET in Kazakhstan. Cosmonaut Sergei Volkov, who arrived on the ISS last September, also returned with Kelly and Kornienko.


The great thing about this, which the article mentions, is astronaut Kelly has a twin who stayed on Earth. So they can literally compare the health results and DNA of two identical people to measure the effects that a year in orbit had on one of them. The medical results that come from that are priceless.
