Title: Rockets and Satellites


1
Rockets and Satellites
  • EQ How do rockets travel in space?

2
How Rockets Work
  • A rocket moves forward when gas expelled from the
    rear of a rocket pushes it in the opposite
    direction
  • Basic law of physics
  • For every force, or action, there is an equal and
    opposite force or reaction.

Rockets in Space
  • A rocket moves forward when gases expelled from
    the rear of the rocket push it in the opposite
    direction
  • In a rocket, fuel is burned to make a hot gas
  • This hot gas is forced out of narrow nozzles in
    the back of the rocket, propelling the rocket
    forward

Multistage Rockets
  • First rockets were developed by the Chinese in
    the year 1000
  • They used gunpowder for fuel
  • Gunpowder burned quickly so there was not
    enough to get the rocket out of the atmosphere
  • Gunpowder is extremely explosive

Robert H. Goddard
  • American Scientist
  • In the 1920s he experimented with fuels and found
    a liquid fuel that provided continuous power

Konstantin Tsiolkovsky
  • Russian Scientist
  • Developed a rocket that breaks apart as fuel is
    used
  • Once a stage uses up its fuel, the container
    drops off and the next stage ignites

Saturn V
  • Carried astronauts to the moon
  • Developed in 1950s and 1960s
  • Multistage rocket

Artificial Satellites
  • October 4, 1957 Soviet Union successfully
    launched a satellite into orbit around the earth
  • Satellite a natural or artificial object that
    revolves around an object in space
  • The name of the satellite was Sputnik 1

Yuri Gagarin
  • First person in space
  • Orbited earth on April 12, 1961

Geosynchronous Orbits
  • Orbits that hold satellites that revolve around
    the earth at the same rate the Earth rotates
  • Used to relay tv signals and map weather patterns

NASA began development of new communication
satellites in 1960, based on the hypothesis that
geosynchronous satellites, which orbit Earth
22,300 miles (35,900 km) above the ground,
offered the best location because the high orbit
allowed the satellites' orbital speed to match
the rotation speed of Earth and therefore remain
essentially stable over the same spot.

Space Station
  • Large space satellite in which people live for
    long periods of time
  • International Space Station
  • Built by 16 countries

Space Shuttle
  • Reusable space rocket used to shuttle back and
    forth between earth and space to launch
    astronauts and equipment into space
