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.

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

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
