The Space Shuttle enters Earth orbit
The Space Shuttle reveals a belly covered with thousands of
individual thermally protective silica tiles, scorched and charred from
numerous reentries of past missions.
Nine
minutes after launching from NASA's Kennedy Space Center in Florida, the US
Space Shuttle shuts down its engines, shed's its massive external fuel tank,
and enters freefall 60 miles above the Atlantic ocean. Traveling "upside
down" at 16,700 miles per hour, the Shuttle has already put over a
thousand miles between itself and the launch tower. If uncorrected however,
the current trajectory will bring the orbiter back to Earth
somewhere halfway around the globe. In order to propel the Shuttle to it's
final orbit--anywhere from 116 and 600 miles high--the two
Orbital Maneuvering System thrusters (the smallest nozzles near the tail) will fire until the
target
altitude is reached.
