The launch of space shuttle Discovery, planned for early this morning, was called off deep into the countdown due to inclement weather at Kennedy Space Center in Florida. NASA will try again in the wee hours of Wednesday, weather permitting. The launch time is set for 1:10 a.m. (Eastern Daylight Time)—which would provide sky-watchers another chance to see the orbiter climbing in the night sky—and the space agency forecasts a 70 percent chance of favorable conditions.
This is hardly the first time, of course, that a launch has been postponed in Florida's mercurial climate. Last month's STS-127 mission of space shuttle Endeavour to the International Space Station was pushed back three times due to weather, before the skies finally cleared. At that time, we checked in with space historian Roger Launius of the Smithsonian National Air and Space Museum to find out why NASA shoots all their rockets for manned missions from such a stormy place—you can read our Q&A with Launius here.

Space shuttle Discovery touched down safely at 3:14 P.M. (Eastern Daylight Time) at Kennedy Space Center in Florida, completing its 13-day mission to the International Space Station (ISS). The landing time was pushed back from 1:39 P.M. due to uncertain weather at the landing site earlier in the day.
Discovery delivered a 45-foot (14-meter) truss segment to the ISS, completing the station's 335-foot (102-meter) "backbone," as well as the final set of solar arrays needed to power the station once its crew swells from three to six in the coming months. The ISS now boasts 38,400 square feet (3,570 square meters) of U.S. solar panels, nearly a full acre, generating about 120 kilowatts of electricity. (Unlike solar-powered buildings here on Earth, the space station doesn't need to worry about cloud cover.)
