U.S. astronaut launching on history-making mission

NASA astronaut Scott Kelly is preparing to leave Earth for a very long time -- and to make U.S. spaceflight history. On Friday at 3:42 p.m. ET, Kelly will ride a Russian Soyuz rocket to the International Space Station and stay there nearly a year, twice as long as any U.S. astronaut has ever stayed on the space station.
