NASA delays shuttle's return to Earth

CAPE CANAVERAL, Fla. (Reuters) - Cloudy skies over its Florida landing site on Monday forced NASA to postpone the space shuttle Discovery's return to Earth, prolonging by at least a day the first shuttle mission since the 2003 Columbia disaster. 

Flight directors tried twice to bring Discovery back to Earth after 13 days in orbit but decided the weather was too unpredictable to be sure shuttle commander Eileen Collins would have a clear view of the 3-mile (4.8-km), canal-lined runway at the Kennedy Space Center.
