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.
