The space shuttle discovery completed a ______ mission upon its return to the Kennedy Space Centre.

The Space Shuttle Discovery made a real night landing at the Kennedy Space Center early on Thursday. The night landing, the 11th in the centre’s 94 shuttle missions, ended a 10-day mission to outfit the orbiting international space station. Although the space craft created a solid boom that can be heard along much of Florida’s eastern seaboard, witnesses on the ground could not see the orbiter until it was directly over the one-way lights. Scattered showers off the Florida coast had threatened to postpone the shuttle’s return. But broadcasters gave a green light when they decided no rain will fall within 48 kilometres of the space centre.
