Introduction
• Five hundred years curiosity led Europeans to explore new places on earth.
• We want to learn more about the other planets.
• Venus and Mars are earths two closets neighbors in space.
Exploring Venus
• Venus is covered in mostly craters.
• These craters were formed when meteors crashed into the surface.
• Venus temperature can reach up to 867F 464C.
Early missions
• Sputnik 1 was the first human made object to orbit earth.
• Mariner 2 did not land on Venus it did a flyby mission.
• Mariner 2 sent back information about planet Venus.
Early Missions
• In 1970 another soviet spacecraft went to Venus.
• In 1974 Mariner 10 became the first spacecraft two visit the two planets.
• Mariner 10 took more then 4000 photos as it flow past venus.
Early missions
• In may of 1989 the united states launched the Magellan spacecraft.
• IN 1997 the Cassini orbiter flew by Venus.
• The spacecraft traveled to Saturn.
Exploring Mars
• Mars can reach a temperature of 60F 15C during its summer.
• But its winter temperture drop to 225F below zero -140C.
• The tallest mountain on mars is Olympus. moon
Early missions to mars
• Scientist began looking for life on mars.
• From 1960 to 1962 the Soviet union launched the fire spacecraft they hoped would reach mars.
• All five failed.
Early missions to mars
• Mariner 4 preformed
the first successful mars mission yet.
• The 1980s brought two failed attempts to reach mars.
• The pathfinder was launched through space for several months.
Future exploration
• Scientist launched messenger in august 2004.
• They launched Venus Express in November 2005.
• Messenger will fly past venus twice
Future exploration
• Each time messenger will send back information.
• Then it will continue to mercury.
• Mercury is the closets planet to the sun.
Future exploration
• The European space agency is in charge of space travel for European countries.
• The venus express is the ESAS first probe to go to venus.
Future exploration
• The venus express will explore the planets stormy atmosphere.
• Scientist hope this will help them learn more about global warming
• Venus has a thick layer of clouds.
Future exploration
• Venus clouds trap heat and raise the planets temperature.
• These missions may use robot planes balloons to explore mars.
• NASA is also planning to send out scouting missions in 2009.
Future exploration
• In 2011 the first sample return mission is expected to launch.
• This will send a rover to mars and collect rock and soil.
• The rover will then blast off from mars and return to earth,.
