The longest continuous stay in space to date is 437 days, by Russian Cosmonaut Valeri Polyakov, who stayed on the Russian Space station MIR.
Having said that, when Scott Kelly (NASA astronaut) is finished his year mission, he would have totalled 522 days in space over 4 missions.
Still, no one has beaten Valeri’s 437 days in one trip!
