Paper Abstract:
Purpose & history of mission. Discoveries of Voyager ! & 2. Modification of original plans. Outline.
Paper Introduction:
One of mankind's great dreams is the discovery of other planetary systems and the ability to travel to them, and a first step in fulfilling this dream is the unmanned probe represented by the Voyager Interstellar Mission. This is a difficult mission by any measure. Voyager I was launched September 5, 1977, and after it has been speeding along for more than 20 years, it is now 6.8 billion miles away from Earth traveling at nearly 51,000 miles per hour. In cosmic terms, that is only about 10 light hours away. However, the closest star to Earth is Proxima Centauri, which is 4.3 light years, or 25 trillion miles, away. If Voyager were pointed in the right direction, it is calculated that it would take some 74,000 years to make the trip. However, effective interstellar missions must occur on a human time scale preferably within an individual's lifetime -
