NASA announced the official launch time of the Space Shuttle Columbia on Wednesday, as part of its new policy of keeping the time secret until 24 hours before launch. If all goes well, the shuttle will lift off from Florida’s Cape Canaveral at 1539 GMT (10:39 am EST). The shuttle won’t dock with the International Space Station this mission, so there is a long launch window of 2.5 hours. The weather looks excellent for launch.
