CAPE CANAVERAL, Fla. – Space shuttle Discovery wraped up a 15-day delivery mission to the International Space Station (ISS) landed safely in Florida on Tuesday morning. Discovery, completed one of NASA's few remaining shuttle flights. The shuttle Discovery, and the Fleet, retires later this year. 

Shuttle commander Alan Poindexter guided Discovery to a 9:08 a.m. EDT (1308 GMT) touchdown at the Shuttle Landing Facility at NASA's Kennedy Space Center, following a flight path that took the shuttle over much of North America before avoiding rain showers falling over most of central Florida. Twin sonic booms broke through the morning sky to announce the shuttle's homecoming after a 6 million-mile trip.
