Space shuttles are huge vehicles
that carry astronauts millions of miles into the cold space. Large engines
and rockets power the high-tech space shuttles. Astronauts ride in the
orbiter section of the shuttles. An orbiter is the airplane like part
of the space shuttle where the astronauts ride. When the space shuttle
lifts off the ground it gets to space only 10 minutes after.
A space shuttle needs a whole
lot of power to blast off into space. The brownish external tank holds
engine fuel. This fuel gives power to these main engines. Astronaut's
control three main engines from the flight deck where is where all control
happens. Two solid boosters give a shuttle extra power during the very
powerful lift-off. Smaller engines called thrusters help change a shuttles
speed on the trip into space.
Two solid rocket boosters
give a space shuttle a powerful thrust. The boosters fall to the ocean
only two minutes after lift off. Workers will clean and the empty rocket
boosters after they fall into the sea. Then they will refill them for
the next flight.
The brown external tank outside
the orbiter holds fuel. The fuel lasts about nine minutes. Astronaughts
separate the empty tank from the shuttle. This makes the shuttle lighter
and easier to fly. The external tank breaks continues into space.
