Rain threatens to delay space shuttle's return
None
Rain threatened to delay space shuttle Discovery's homecoming Monday and keep its seven astronauts in orbit an extra day.
Discovery was scheduled to land at 8:48 am, two weeks to the day since it rocketed away to the International Space Station. Its re-entry path was going to cut diagonally across North America from northwest to southeast, providing a phenomenal light show, weather permitting. (AP)
