  13. Other Small Missions • Lunar Prospector: found large amounts of ice on the Moon • Near-Earth Asteroid Rendezvous (NEAR): sent up-close imagery and data from the asteroid, Eros Lunar Prospector

  14. Space Incorporated • Commercial investment in space surpassed government spending for the first time in the 1990’s • Commercial uses of GPS soared • Communications satellites fueled demand for cell phones and high-speed digital data transmission • Worldwide market for launch service evolved • Pegasus—launched from commercial aircraft • Converted ICBMs—peaceful use of decommissioned weapons

  15. The New High Ground • 1990-1991 Persian Gulf War highlighted pivotal role space assets play in modern warfare • GPS allowed navigation across faceless desert • Early warning for enemy’s tactical-missile launches (Defense Support Program) helped forces prepare and intercept • Weather satellites predicted sand storms • Intelligence satellites provided imagery on troop movement and battle-damage assessment

  16. The New High Ground • USAF identifies other ways to exploit space power • Global awareness • Intelligence, surveillance and reconnaissance • Weather prediction • Early warning • Global reach • Ability to deploy troops or weapons anywhere in the world • Global power • Command, control and communications • Weapons targeting

  17. The New High Ground Defense Support Program (DSP) GPS Block 2F

  18. The Future • People still willing to take great risks for further exploration and discovery • 1986 Challenger accident • 2003 Columbia accident • Continued scientific experiments onboard the International Space Station • Continued inexpensive uncrewed missions to other planets will gather information • 21st Century: crewed mission to Mars? • Return to the Moon?

  19. Organizing the Air Force for Space Operations • A Beginning • Early Visions of Space Operations • The Gaither Commission • The First Space Tracking Stations • The First Satellite • From “Air” to “Aerospace” Unit 1, Chapter 2 , Lesson 2: Exploring Space SECTION 2.3

  20. Organizing the Air Force for Space Operations • NORAD Begins • Anti-Ballistic Missile Programs • Strategic Air Command’s Era • A New Command Is Born • Consolidating Space Missions Unit 1, Chapter 2 , Lesson 2: Exploring Space

  21. A Beginning • Use of the V-2 in World War II showed rockets had military applications • US use of a nuclear weapon to end the war in the Pacific heightened mistrust between Russia and the West • Postwar recruitment of German scientists by both the West and Russia advanced early rocket programs Unit 1, Chapter 2 , Lesson 2: Exploring Space

  22. Early Visions of Space Operations • RAND corporation published Preliminary Design of an Experimental World-circling Spaceship • Soviets’ test of first hydrogen bomb and suspected development of missile delivery systems heightened drive for early-warning and tracking systems Unit 1, Chapter 2 , Lesson 2: Exploring Space

  23. The Gaither Commission • Commission appointed by President Eisenhower to assess civil defense posture following a nuclear attack • Commission also assessed whether a US counter strike was possible • Showed counterstrike unlikely due to inability to predict attack until first warhead fell • Accelerated US ICBM development and other strategic programs Unit 1, Chapter 2 , Lesson 2: Exploring Space

  24. The First Space Tracking Stations • Minitrack • Built by the Naval Research Laboratory • Network of simple ground tracking stations developed to track a proposed new satellite under the Vanguard Program • Moonwatch • Smithsonian Institution developed a network of Baker-Nunn Cameras • Sought civilian volunteers to phone in when they saw the satellite Unit 1, Chapter 2 , Lesson 2: Exploring Space

  25. The First Satellite • Launch of Sputnik shocked the US and highlighted Minitrack’s inability to accurately track Sputnik • Sputnik tracking mainly from Moonwatch teams • Department of Defense’s Advanced Research Projects Agency (ARPA) established Project Shepherd as an effort to improve Minitrack’s tracking problems Unit 1, Chapter 2 , Lesson 2: Exploring Space

  26. From “Air” to “Aerospace” • 1959 change to the Air Force mission added the word “aerospace” to recognize space’s new importance • ARPA opened a system program office to develop equipment and techniques to track space objects and incoming Soviet missiles • By the mid 1960s, had three radar sites that could give 15-minute warning of missile impact • Radar sites also tracked space objects Unit 1, Chapter 2 , Lesson 2: Exploring Space

  27. NORAD Begins • North American Air Defense Command (NORAD) established in Sep 1957 • Joint effort with Canada • Mission to defend combined airspace of US and Canada • Development of submarine-launched ballistic missiles (SLBMs) by US and Soviets created a need for more tracking stations • Air Force developed several radars on the Atlantic, Pacific and Gulf Coasts • Entire system operational by 1972 Unit 1, Chapter 2 , Lesson 2: Exploring Space

  28. Air Force Developments • SLBM warning augmented by Air Force’s new space-tracking radar in Florida • Air Force brought more tracking ability by developing PAVE PAWS radar sites • Powerful phased-array radar—steerable beam • Sites established in Massachusetts, California, Georgia, and Texas Unit 1, Chapter 2 , Lesson 2: Exploring Space

  29. Anti-ballistic Missile Programs • DoD attempted to establish a defense shield against Soviet missile attack • Covered one area of US: ICBM sites in North Dakota to enable US counter strike if attacked • Shut down by congress in 1976 due to great expense and low probability of success • Air Force took over the system’s radars to • Aid early warning for SLBMs over Hudson Bay • Add coverage for ICBM early warning • Improve accurate space tracking Unit 1, Chapter 2 , Lesson 2: Exploring Space

  30. Strategic Air Command’s Era • Strategic Air Command (SAC) took over administrative control of people and equipment in space surveillance and missile-warning missions • NORAD maintained operational control over these missions • Several studies in the 1970s suggested the need for reorganization Unit 1, Chapter 2 , Lesson 2: Exploring Space

  31. A New Command is Born • Space Command began in 1982 under General James V. Hartinger • SAC passed operational control of at least 25 space-surveillance and missile-warning sensors to Space Command Air Force Space Command Headquarters Unit 1, Chapter 2 , Lesson 2: Exploring Space

  32. Merging Space Missions • Air Force Systems Command controlled much of the Air Force’s launch systems and satellites • Systems Command not always sensitive to the needs of the warfighters USING assets • AF Space Command sought to take over these functions to service the warfighter more directly Unit 1, Chapter 2 , Lesson 2: Exploring Space
