[QUOTE="Tom.G, post: 6643781, member: 581973"] An interesting article on some of the history of, and discoveries by, the 44+ year old Voyager spacecraft s. The bean counters originally planned a 4 year mission for Voyagers 1&2. However, the scientists and engineers involved saw a golden opportunity that wouldn't repeat for another 176 years. The crafts use thermoelectric power from decaying radioactives, and they are decaying. There is probably enough power for another 10 years if some of the experiments are shut down. Voyager 2 is now 18 Billion (18×10[sup]9[/sup]) miles away, with a oneway radio link delay of 18hrs. (per the article) using a 23 Watt transmitter and 12ft. dish antenna.
