Bell Work:

Bell Work

• What is the name of the man who first invented
  the rocket?
• What are the names of the first four planets?
  What is the special name given to these four
  planets?

2
Mars

• Mars is called the red planet.
• The reddish color is caused by rust (iron oxide)
  in the soil.
• Most studied planet other than earth.
• Viking 1 and 2 spacecrafts landed on mars in
  1976.
• Pathfinder spacecraft landed on Mars in 1997.
• These three space crafts give us most of the
  information we know about Mars.

3
Mars

• Mars is a cold planet because of its thin
  atmosphere and distance from the sun.
• The pressure is so low in the atmosphere that any
  liquid water would quickly boil away.
• The only water found on Mars is in the form of
  ice.

4
Martian Terrain

• Dry river beds on Mars indicates that there
  possibly was water in the past.
• Mars now has two polar icecaps that contain
  frozen water and carbon dioxide.

5
Martian Volcanoes

• Mars has two volcanic regions.
• Olymups Mons is the largest mountain in the solar
  system is a extinct shield volcano.
• Mars has a gigantic equatorial rift valley, the
  Valles Marineris. This canyon system stretches a
  distance equivalent to the distance from New York
  to Los Angeles Arizona's
• Grand Canyon could easily
• fit into one of its side canyons.

6
Moons of Mars

• Phobos and Deimos
• Irregular shapes
• Very dark surfaces
• Could be captured asteroids

Jupiter

• The first of the outer planets.
• Is the largest planet!
• Considered to be a gas giant made mostly of
  hydrogen and helium.
• Known for its giant red spot.
• This spot has a diameter three
• times that of earth it was
• thought to be 1.5 times
• but is larger!

11
Jupiter

• The giant red spot is a long lasting storm
  system.
• Jupiter radiates, or gives, much more energy into
  space than it receives from the sun.
• Two Pioneer missions, 2 Voyager missions and 1
  Galileo mission have all studied Jupiter.
• Galileo sent a probe to the Jupiters atmosphere
  in 1995 that sent back data on the atmosphere
  composition, temperature and pressure.

12
Jupiters moons and rings

• Jupiter has 63 moons and a ring system. The four
  of Jupiters natural satellites are Io, Europa,
  Ganymede, and Callisto.
• Io has active volcanoes, and Europa has the
  possibility of a water environment friendly to
  life.
