Weather delays shuttle's return

Nasa has passed on the first opportunity to bring shuttle Discovery back to Earth because of poor weather at the Kennedy Space Center.
Low cloud and light rain around the Florida spaceport break the agency's landing rules for the orbiter.
Mission Control says a second opportunity for Discovery exists at 1023 local time (1423 GMT).
Discovery has spent two weeks at the space station, stockpiling it with supplies, experiments and spare parts.
