The ballistic category of atmospheric vehicles includes missiles, launch ve-
hicles, and entry capsules. Some missiles and launch vehicles incorporate fi ns
as aerodynamic stabilizing and control surfaces. The spacecraft are also catego-
rized according to their missions, such as low-earth orbit, medium-earth orbit,
geosynchronous orbit , lunar, and interplanetary spacecraft. Each mission is
defi ned by the payload, and orbital elements of the fi nal orbit. Of course, a
reusable launch vehicle, such as the space shuttle, is also a spacecraft with a
unique mission.
