- 3. Essential Components • EachSpace Shuttle was a reusable launch system composed of three main assemblies: the reusable orbiter, the expendable External Tank, and the two reusable Solid Rocket Boosters . • Only the Orbiter entered orbit shortly after the tank and boosters are thrown away. The orbiter was the part that looked like an airplane, • The external tank was a large fuel tank. Supplies liquid nitrogen and oxygen to main engines • The solid rocket boosters looked liked two thin rockets. Provides 83% of total thrust needed for launch
