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?

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.

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.

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.

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.

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!

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 Jupiter’s atmosphere in 1995 that sent back data on the atmosphere composition, temperature and pressure.

Jupiters moons and rings• Jupiter has Jupiter has 6363 moons and a moons and a ring ring

systemsystem. The four of Jupiter’s natural . The four of Jupiter’s natural satellites are satellites are IoIo, , EuropaEuropa, , GanymedeGanymede, , and and CallistoCallisto..

• Io has active volcanoes, and Europa has Io has active volcanoes, and Europa has the possibility of a water environment the possibility of a water environment friendly to friendly to life. .
