The longest American space voyage ever is now over and scientists are about to swarm over Scott Kelly. When the astronaut touched down yesterday in Kazakhstan, he set a record for the longest spaceflight by an American. Kelly now holds the record of 340 days in space… and comparison with his twin brother, former astronaut Mark Kelly, offers a unique opportunity. We hear what's in store for Kelly and from America's former record holder.
