Probes

1
Probes

• A probe is an unmanned, unpiloted spacecraft
  carrying instruments intended for use in
  exploration of outer space or celestial bodies
  other than Earth.
• Three Types of Probes
•  
• Fly-by Probe Passes a planet collecting
  information as it travels.
• Orbiter Probe Flies closer to a planet to
  examine the atmosphere
• and survey the service.
• Land Probe touches down on the planets surface.
  

2
Mars Reconnaissance Orbiter

• On a search for evidence that water persisted on
  the surface of Mars for a long period of time.

3
Galileo

• Sent to study Jupiter and its moons.

4
New Horizons Space Probe

• Flyby Pluto and gather information on its
  atmosphere and surface.

5
SOHO Probe

• On a mission to study the sun from orbit.

6
Mars Exploration Rovers

• Gather data of Mars from the ground. It takes
  photographs and data from rocks and soil on the
  surface.

7
Cassini-Huygens Probe

• On a mission to orbit Saturn. It is measuring
  atmosphere, wind, and cosmic dust.

8

• Power Sources for Satellites
• Batteries, Solar Panels, Nuclear Power, Heat
  Generators (dish of mirrors that
• reflect the heat of the sun)

9
Design a Probe

• Draw a diagram of a probe that would collect dust
  particles from Comet Halleys tail. Be creative,
  but realistic. Think about the challenges
  scientists face when collecting dust particles
  from a moving object in space.
• Your probe must include
• Power Source
• Device to take pictures or images
• Collection Device for the dust particles
