Most
rockets sit on a launch pad until they blast off. But one
special little rocket needs no launch pad at all. This
rocket, called Pegasus, recently put NASA's new GALEX space
telescope into Earth orbit.
Pegasus rockets are very small and can carry only a small
spacecraft that weighs less than 450 kilograms (1000
pounds). GALEX weighs only 280 kilograms (about 617 pounds).
Pegasus works by hitching a ride (with the spacecraft
inside) under the belly of an L-1011 jumbo jet named
Stargazer. Stargazer takes the Pegasus up to about 12
kilometers (40,000 feet). This is about as high as this
plane can fly. Then, the plane lets go of Pegasus. For a few
seconds Pegasus falls freely, waiting for the plane to get
out of the way. Then Pegasus fires its first stage engine
and heads for space, ferrying the spacecraft the rest of the
way to Earth orbit.
It is much less expensive to launch a small spacecraft using
Pegasus than using a larger rocket that pushes off from the
ground. |
