The Space Shuttle is a reusable spacecraft designed to lift payloads into |
||
orbit and glide back to earth. It consists of the aircraft-like orbiter, the |
||
external fuel tank which supplies the liquid hydrogen fuel to the orbiter's |
||
three main rocket engines, and two solid rocket boosters (not shown). The |
||
model pictured here shows the stage in the launch when the orbiter is |
||
rocketing skyward still attached to the external fuel tank after the two empty |
||
solid rocket boosters have been jettisoned. About nine minutes after lift off |
||
the external fuel tank is also jettisoned leaving the orbiter free to rocket |
||
itself into final orbit. |
