  1. ROCKETS How Do They Work? By: Sam Houff 5-5-05

  2. Fuel • Rockets have lots of fuel • The fuel weighs twenty times the orbiter. • The fuel is used up quickly

  3. Fuel • Dr. Robert H. Goddards early rockets used a combination of Gasoline and Liquid Oxygen • Apollo Boosters- Kerosene and Liquid Oxygen • Space Shuttles: Liquid Hydrogen and Liquid Oxygen.

  4. How Does A Rocket Work • Rockets rely on Newton’s 3rd Law. The Law states that for every action, there is an equal and opposite reaction.

  5. Early Rockets • Early rockets were used in combat. The earliest date to China. • Dr. Robert H. Goddard developed one of the earliest liquid rockets.

  6. Booster Rockets • Booster Rockets are the rockets that thrust space shuttles into space. They are needed because of the shuttles lack of thrust power.

  7. Booster Rockets • A shuttles first stage of rockets are the boosters. • The booster rockets are dropped back to Earth after there fuel is used up, leaving only the shuttle.

  8. Ion Rockets • Much more efficient than a normal rocket. • Works by stripping neutrons from the atoms, therefore harnessing the positive energy.

  9. Obstacles of Flight • Space debris • Shuttles dump trash in space • The red areas on the picture are space debris.
