  2. We humans are motivated to dream, to explore, to discover, to learn. "Dream no small dreams for they have no power to move the hearts of men." --  Johann Wolfgang von Goethe “It is difficult to say what is impossible, for the dream of yesterday is the hope of today and the reality of tomorrow.” -- Robert H. Goddard

  3. Dr. Robert H. Goddard 1882-1945

  4. The beginning of space exploration First view of Earth from a camera on V-2 #13, launched October 24, 1946. White Sands Missile Range/Applied Physics Laboratory

  15. Wonders of Robotic Space Exploration • “Humans in space” have generated a grand public interest and excitement. Yet, it is robotic space explorations that have paid the biggest dividends of remarkable new knowledge and useful applications. E.g., • Solar physics and space weather. • Planetary exploration. • Astronomy and astrophysics. • Earth remote sensing, climate and weather. • Global Positioning System. • Communication and broadcasting. • Military intelligence. • Today we’ll touch on only a few exciting experiments.

  31. Image taken from: http://map.gsfc.nasa.gov/universe/bb_tests_cmb.html Variation from place to place on the sky is as much as about ± 0.004ºK.

  34. The CMB bottom line. • Velocity of our solar system through the universe equals 368 km/sec. • Age of the universe is 13.75 billion years (since the big bang). • The universe is made up of: 4% ordinary matter 23% dark matter 73% dark energy Oh, the adventure and wonder of space exploration!
