  1. Pigeons to Payloads: Introducing Remote Sensing http://www.unc.edu/courses/2006fall/geog/477/001/www/ Geography 477: 24 August 2006

  2. Synoptic – Unified View of the Whole Repeatable – Observe Dynamic Processes Information Rich – Massive Inferential Power Geolocated & Spatially Complete

  3. Father of Modern Rocketry – Robert Goddard After 17 years of theoretical and experimental work, Goddard achieved the first successful flight of a liquid-fueled rocket on March 26, 1926. The rocket flew 184 feet in 2.5 seconds and landed in a cabbage patch on his Aunt Effie's farm in Auburn, Massachusetts.

  4. Rough Sequence of Events – Space Imagery • Rockets • Satellites • Space Studies • Communications • Weather • Earth Science – Land, Atmosphere, Ocean • Mapping & Surveying

  5. Boston from a Tethered Balloon - 1860

  6. Alfred Nobel obtained this rocket’s-eye view of a Swedish landscape - 1897

  7. Post Quake San Francisco 1906 – Kites used to send camera aloft – George Lawrence

  8. Scott Haefner’s Kite photo of SF Bay – 2006 http://scotthaefner.com/kap/

  9. Sputnik 1 - The First Satellite – 4 October 1957

  10. Laika on Sputnik II; 3 November 1957

  11. Vanguard 1; 1958 First Solar Powered Earth Orbiting Satellite 6,431,8??,??? Miles so far. Oldest man made object in space Sputnik I Sputnik II Explorer (US) Vanguard I

  12. Chronology of Sputnik/Vanguard/Explorer Events 1957-58  October 4, 1957 USSR: Sputnik 1 (83.6 kg)  November 3 USSR: Sputnik 2 (508.3 kg), Dog Laika as passenger  December 6 USA: Vanguard TV-3 explodes on launch pad  January 31, 1958 USA: Explorer 1 (14 kg), first US satellite, discovers Van Allen radiation belts  February 3 USSR: First try to launch Sputnik 3 fails  February 5 USA: A second Vanguard try fails  March 5 USA: Explorer 2 fails to orbit  March 17 USA: Vanguard 1 (1.47 kg) successfully orbits, establishes the pear-shapedness of the Earth  March 26 USA: Explorer 3 orbits, collects radiation and micrometeoroid data  April 28 USA: Another Vanguard fails to orbit (third failure)  May 15 USSR: Sputnik 3 (1,327 kg) orbits, carrying large array of scientific instruments, but tape recorder fails. May 27 USA Vanguard fails for the fourth time  June 26 USA Vanguard fails for fifth time July 26 USA Explorer 4 orbits and maps Van Allen radiation belts August 24 USA Explorer 5 fails to orbit  September 26 USA Vanguard fails for the sixth time

  13. April 1960: TIROS (Television and Infrared Observational Satellite) – Nine additional TIROS satellites subsequently launched through 1965. • August 1964: NIMBUS 1 – Meteorological satellites with 3-axis stabilization, allowed sensors to continuously point towards Earth. • First sun-synchronous satellites.   • Six more Nimbus satellites subsequently launched through 1978 • provided continuous coverage of the earth for the first time. Current NOAA polar orbiting satellites are daughters of Nimbus.

  14. 1972 – Earth Resources Technology Satellite (ERTS-1) Launched and christened Landsat - MSS

  15. 1975 1986

  16. SPY STUFF CORONA, ARGON, LANYARD KH (keyhole) Cameras August 1960-1972 about 145 Missions Resolutions progress from tens of feet to inches GAMBIT 1963-1984 up to 6 inch resolution HEXAGON (18 Launched) KENNAN INDIGO-LACROSSE-VEGA MidAirRetrieval until 1976

  17. CORONA

  19. Other Leaks 1980 KH11 photos left behind during botched Iran Hostage Rescue Mission 1984 Accidental publication of KH9 data in congressional hearing

  20. KH11 Soviet Ship Building Facility – Janes Defense Weekly 1984

  21. mid-air retrieval

  22. A failed mid-air retrieval – Genesis Solar Wind Mission – 8 September 2004

  23. “The Blue Marble" Photo of Earth taken on 7 December1972 by the crew of the Apollo 17 spacecraft at a distance of about 45,000 kilometers or about 28,000 miles. [1]. It is one of the most widely distributed photographic images in existence. The image is one of the few to show a fully lit Earth, as the astronauts had the Sun behind them when they took the image. To the astronauts, Earth had the size and appearance of a child's glass marble.

  24. Phytoplankton Bloom

  25. Function of Earth Ecosystems
