That's how long Russian cosmonaut Gennady Padalka has spent orbiting Earth. Upon returning from the International Space Station (ISS) today, Mr. Padalka became the most-experienced space flier on the planet, breaking the previous record for the longest amount of time spent in space, held by his countryman Sergei Krikalev, who completed 803 days over 6 missions. In just five missions, Padalka has him beat by 76 days. "I like to fly," he said in March, before launching on his latest mission. The space frontier has transformed during Padalka's twenty-plus years as a cosmonaut: The Mars Pathfinder and the Phoenix Mars lander explored Mars, the Near Earth Asteroid Rendezvous (NEAR) spacecraft landed on asteroid Eros, Cassini investigated Saturn's rings, Stardust brought comet dust back to Earth, and Dawn became the first spacecraft to orbit an asteroid.
