From Space to Your Front Door

By James Gilbert Pynn

Before the Eagle had landed, the Soviets had threatened to dominate space. When the Soviet Space Program successfully sent Sputnik into orbit in 1957, the so-called free world was in a panic. Congress reacted with swiftness reserved for a national crisis. Indeed, for many Americans, the perceived superiority of the Soviet program was tantamount to a crisis. President Eisenhower moved quickly to establish both NASA (National Aeronautics and Space Administration) and DARPA (Defense Advanced Research Projects Agency) in 1958.

Declaring "For the Benefit of All," NASA launched the Explorer 1 satellite on January 31, 1958. Led by the former head of the German rocket program, Wernher von Braun, NASA immediately began to explore the possibility of sending human beings into space. Dubbed Project Mercury, this program involved seven original astronauts, of whom, Alan Shepard became the first American into space, while John Glenn would become the first American to orbit the earth.

With the Space Race essentially in hand, NASA began implementing a new tracking system, called the Global Positioning System (GPS). The system involved the use of satellites to track the position and location of both spacecraft and intercontinental ballistic missiles. Initially developed by the Navy, the first successful GPS tracking system was dubbed Transit, and used five satellites to triangulate positions around the globe.

For decades the GPS system was classified and reserved only for military and governmental use. Then, in 1983, a Soviet interceptor aircraft shot down the civilian Korean Air airliner KAL 007, killing all 269 people on board. The plane had strayed into Soviet airspace and although the Soviet had probable cause to destroy the perceived threat, it was determined had the airliner had accurate navigational systems, the tragedy could have been avoided. President Ronald Reagan subsequently announced that civilians and civilian agencies should have access to the GPS tracking systems.

Now, most people couldnt find their front door without a GPS system (usually in their cellphones). It has become an integral part of modern 21st Century culture. Not only has it become the preeminent navigational system for cars, but the scientific community has used it to track wild and domestic animals and migration patterns. Law enforcement uses GPS tracking to find stolen cars and keep tabs on criminals on bail or probation. Now, not only can someone find where they are on a city grid, but also he or she can find nearby businesses and restaurants. The uses, and the wonders, never end. - 14915
