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 planet’s surface.

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

Sent to study Jupiter and its moons. Galileo Sent to study Jupiter and its moons.

New Horizons Space Probe Flyby Pluto and gather information on its atmosphere and surface.

On a mission to study the sun from orbit. SOHO Probe On a mission to study the sun from orbit.

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

Cassini-Huygens Probe On a mission to orbit Saturn. It is measuring atmosphere, wind, and cosmic dust.

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

Design a Probe Draw a diagram of a probe that would collect dust particles from Comet Halley’s 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 Image of the nucleus of Comet Halley from Giotto Spacecraft (European Space Agency - ESA) in 1986.
