  1. space station
  2. solid fuel rocket
  3. Robert Goddard
  4. escape velocity
  5. moon rocks
  1. a oxygen is mixed with fuel (dry-explosive chemical). an example is a firework. Once a solid fuel rocket is ignited it burns until all the fuel is gone
  2. b a large artificial satellite on which people can live and work for long periods
  3. c the velocity an object must reach to fly beyond a planet's or moon's gravitational pull
  4. d American physicist who designed rockets and went a step farther by building rockets to test his designs
  5. e minerals that make up moon rocks are the same minerals that are found on Earth. In some moon rocks these minerals combine to form kinds of rocks that are not found on earth

5 Multiple choice questions

  1. solid fuel, liquid fuel, and electrically charged particles of gas

  4. oxygen and the fuel are in liquid form and stored in separate compartments. When the rocket fires the fuel and oxygen are pumped into the same chamber and ignited. Advantage is that the amount of fuel burned can be regulated by how much liquid fuel and oxygen are mixed together
  5. the condition of experiencing weightlessness in orbit
