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 Mars Facts Distance from the sun 12.7 light-minutes Period of rotation 24 hours, 37 minutes Period of revolution 1 year, 322 days Diameter 6,794 km Surface temperature -123 to 37*C Surface gravity 38% of Earth’s Bell Work: Good afternoon! Make today a great day! Have agenda out on your desk open to today’s date. 1. What are the terrestrial planets? 2. Explain what happens in a solar eclipse. 3. Compare and contrast comets, asteroids, and meteoroids. What’s this? My Very Educated Mother Just Served Us Nachos 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 63 moons and a ring system. The four of Jupiter’s natural satellites are Io, Europa, Ganymede, and Callisto. • Io has active volcanoes, and Europa has the possibility of a water environment friendly to life. Callisto Ganymede Europa Io Jupiter Statistics Distance from the sun 43.3 light-minutes Period of rotation 9 hours, 56 minutes Period of revolution 11 years, 313 days Diameter 142,984 km Temperature -153*C Gravity 236% of Earth’s
