What to Focus On

  • Space missions are of two types: satellites around Earth and spacecraft to outer space.
  • Artificial satellites are manmade objects revolving around Earth or another planet in a fixed orbit.
  • Space technology is useful in communication, weather study, broadcasting, navigation, education, and disaster warning.
  • The Moon is the only natural satellite of the Earth.
  • Artificial satellites are manmade and move in a fixed orbit.
  • Satellite types are based on function: weather, communication, broadcast, navigational, military, and Earth observation.
  • Critical velocity is the tangential speed needed for a satellite to revolve in orbit.
  • Critical velocity is independent of the satellite's mass.
  • Critical velocity decreases as orbit height increases.

Common Mistakes to Avoid

Critical velocity and escape velocity are the same thing.

A heavier satellite needs a higher critical velocity than a lighter satellite.

If the orbit height increases, the satellite must move faster.

Memory Tips

Two broad categories of space missions

Artificial satellite definition

Moon is the only natural satellite of Earth

Sputnik as the first artificial satellite
