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,.
