2. 2 Voyager: The Beginning http://www.universetoday.com/104729/10-historic-moments-in-voyagers-journey-to-interstellar-space/ Voyager 1 launches from the Kennedy Space Center on Sept. 5, 1977. The Voyager spacecraft have been on an extensive mission of discovery that has lasted some 36 years. http://www.youtube.com/watch?feature=player_embedded&v=LIAZWb9_si4

3. 3 Voyager: Communication with the Earth http://deepspace.jpl.nasa.gov/dsn/antennas/34m.html 34-Meter Beam Waveguide (BWG) Antennas34-Meter High-Efficiency (HEF) Antenna Voyager 1 is currently about 12 billion miles away from us. It takes over 17 hours for its signal to reach the earth. Its antenna is 3.7 meters in diameter. “Seeing” its antenna is like seeing a human cell on the moon!
