While reading "Voyager: Seeking New Worlds in the Third Age of Discovery" by Stephen J. Pyne which obviously covers the great history and ongoing missions of the Voyager 1 & 2 Spacecrafts. I cannot help but think of the great Carl Sagan who was such a big part of these awesome missions. Here is Carl Sagan talking a little bit about Voyager's accomplishments from 1990.
The Voyager program is a series of U.S. unmanned space missions that consists of a pair of unmanned scientific probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable planetary alignment of the late 1970s. Although they were officially designated to study just Jupiter and Saturn, the two probes were able to continue their mission into the outer solar system. They are currently on course to eventually exit the solar system. These probes were built at JPL and were funded by NASA. Voyager 1 is currently the farthest human-made object from Earth.
Carl Sagan passed away on December 20, 1996 and he is missed by anyone who has a love of science and a desire to learn about the cosmos in which we are a ever so small part of.
