• Help scientists study weather patterns and
  forecast the weather

6
Types of Satellites (cont.)

• Earth Observing Satellite
• Used to map and monitor our planets resources
  and ever-changing chemical life cycles
• Ex locate mineral deposits, determine size of
  water supply, etc.

This satellite, Aqua, helps scientists study
ocean evaporation and other aspects of the
movement and distribution of Earth's water.

Making your own

• Now that you know about the different types of
  satellites, you will work with a partner to
  create your own, new satellite. Your satellite
  should, in some way, provide beneficial
  information to earths citizens.
• Draw a picture of your satellite and write a
  paragraph explaining its purpose.

Types of Satellites (cont.)

• Scientific Research Satellites
• Some gather info. about the composition/effects
  of the space near earth
• Some record changes in earth and its atmosphere
• Some observe planets, stars and other distant
  objects
• Military Satellites
• Include weather, communications, navigation, and
  Earth observing satellites used for military
  purposes
