  2. Events this week • Sept. 30 – Tuesday – Solar Lab • 2:30-3:30 PM, Kirkwood Obs • Oct. 1 – Wednesday - Kirkwood Obs • 8:30-10:30 PM • Oct. 2 – Thursday – Rooftop • 8:30 PM Swain West WEATHER PERMITTING

  3. 2nd Homework • The Solar System Collaboratory Home • Kepler’s 1st & 2nd laws

  4. Consumer Spending (2006-7) • $20 billion at jewelry stores (US) • $24 billion at liquor stores (US) • $40 billion on weight loss (US) • $23.5 billion on candy and gum (US) • $31 billion on pet toys and supplies (US) • $7 billion on video rentals (US) • $18 billion on makeup (worldwide) • $35 billion on bottled water (worldwide)

  5. 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 billion • Space Ops $6.2 billion • Education $0.15 billion *All astronomy research and space telescopes (as well as space weather, Earth systems and lunar research) are in this part.

  6. Beginnings of Space Exploration • Robert Goddard • Werner von Braun • The Cold War • NASA - 1959 Explorer 1 - 1958 Sputnik & Laika the Space Dog, 1957

  7. Russian Luna 2 – Sept. 1959 crashes on the Moon the first spacecraft to reach a destination beyond Earth Luna 3 – Oct. 1959 lunar flyby first pictures of the far side of the Moon Exploring with Robotic Missions

  8. JFK 1961 • Mercury • Gemini • Six 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”

  9. Societal Benefits of the Apollo Program • Humans can live on the Moon and Mars • Sustainable resources can be found • Hydrogen, oxygen, water • Advances in Technology • Identification of space hazards and risks • Potential new energy sources from space

  10. How Does the Space Program Benefit YOU? • Computer miniaturization • Weather forecasting • Communications • Navigation (GPS) • Global ecosystem & climate observations & resource management Mainframe IBM computer, early 1970’s

  11. What did we learn from the Moon? • Origin and Evolution of the Moon • Foundation for Comparative Planetology • Record of History of Inner Solar System • Initial Guide to Early History of Earth and Mars • Conditions for the Initiation of Life • Lunar Resource Potential • Future Lunar Scientific Potential

  12. Soviet Luna - 1959 Luna 9, 1966 – first soft lunar landing Venera 3 crashes on 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 Early Robotic Exploration (DON’T MEMORIZE NAMES AND DATES)

  13. Mariner to Mars • Mariner 4, 6, 7 fly-bys • 1965, 1969 • craters! • Mariner 9 orbiter • 1970, dust storm! • Craters, Olympus Mons, Valles Marineris

  14. 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 1980’s

  15. 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 The 1990’s – Transition to Modern Exploration Asteroid Ida and its moon Dactyl

  16. Crewed exploration Robotic Exploration Crewed vs. robotic exploration

  17. Challenges Facing Earth: • Predicting Natural Disasters • Providing Ample Clean Water • Mitigating Climate Change • Preserving Farmland • Disposing of Waste • Producing Energy Space programs and associated development can help with all of these

  18. TO DO LIST: • Read NASA website (Oncourse) • Hand in 2nd Homework TODAY (3rd on Fri.) • IN-CLASS QUIZ FRIDAY!! • Activities TUESDAY, WEDNESDAY, & THURSDAY
