What does Space Exploration cost?
NASA budget for FY 2008: ~ $17 Billion
Science $5.3 billion *Exploration $4.0 billion (SS missions)Aeronautics $0.7 billionSpace Ops $6.2 billionEducation $0.15 billion
*All astronomy research and space telescopes (as well as space weather, Earth systems and lunar research) are in this part.
Beginnings of Space Exploration
• Robert Goddard• Werner von Braun• The Cold War• NASA - 1959
Sputnik & Laika the Space Dog, 1957
Explorer 1 - 1958
Exploring with Robotic MissionsRussian Luna 2 – Sept. 1959
crashes on the Moonthe first spacecraft to reach a
destination beyond Earth
Luna 3 – Oct. 1959lunar flybyfirst pictures of the
far side of the Moon
JFK 1961
MercuryGeminiSix Apollo landings
1969-1972
“I believe this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth”
Societal Benefits of the Apollo Program
Humans can live on the Moon and MarsSustainable resources can be found
Hydrogen, oxygen, waterAdvances in TechnologyIdentification of space hazards and risksPotential new energy sources from space
How Does the Space
Program Benefit YOU?

Venus, 1966 Luna 16, 1970, returns
lunar samples Lunokhod 1 (1970)
explored the Moon for 322 Earth days
Mars 2 crashes on Mars, 1973
Venera 9 images from Venus in ‘75
U.S. Pioneer - 1960 Ranger – 1961, 1962 Mariner – 1962
Mars, Venus Pioneer 10 passes the
asteroid belt 1973 Pioneer 10 reaches Jupiter
in ‘73; on to Saturn Mariner 10 photographs
Mercury in ‘74 Viking on Mars, ‘76

Mariner 9 orbiter1970, dust storm!Craters, Olympus
Mons, Valles Marineris
The 1980’s
Just 13 robotic explorers launched (all but two successful)
Voyager spacecraft to outer planets
Magellan to Venus in ‘89– Detailed radar map
In 1986 five spacecraft fly past Comet Halley: Japanese (2), Soviet (2), European
Image from European Giotto mission
The 1990’s – Transition to Modern Exploration
Early missions were feats of technology first images mapping limited scientific
measurements
Later missions were more focused, better defined science Galileo arrives at Jupiter 1996 - 2003 Sojourner/Pathfinder at Mars - 1997 Asteroids and Comets
Asteroid Ida and its moon Dactyl
Crewed vs. robotic exploration
Crewed exploration Robotic Exploration
Challenges Facing Earth:Predicting Natural DisastersProviding Ample Clean Water Mitigating Climate ChangePreserving FarmlandDisposing of WasteProducing Energy
Space programs and associated development can help with all of these
