By: Sam Houff5-5-05
Fuel• Rockets have
lots of fuel• The fuel weighs
twenty times the orbiter.
• The fuel is used up quickly
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.
• Rockets rely on Newton’s 3rd Law. The Law states that for every action, there is an equal and opposite reaction.
• Early rockets were used in combat. The earliest date to China.
• Dr. Robert H. Goddard developed one of the earliest liquid rockets.
• Booster Rockets are the rockets that thrust space shuttles into space. They are needed because of the shuttles lack of thrust power.
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.
Ion Rockets
• Much more efficient than a normal rocket.• Works by stripping neutrons from the
atoms, therefore harnessing the positive energy.
Obstacles of Flight
• Space debris• Shuttles dump trash in
space• The red areas on the
picture are space debris.
