Deep Space
August 2012 Voyager I had made it's way into interstellar space exploring the unknown; it had been 25 years since the launch of both Voyager I and II. On January 23, 2003, we had received a very weak signal from Pioneer 10 and was the last. Pioneer 11's last signal was received in September 30, 1995 and was the end of Pioneer 11's mission; no contact has been attempted to the spacecraft since 1995. These missions show the attempts by mankind to explore what's beyond our solar system and into deep space.

Pioneer 10 & 11Pioneer and Voyager most likely is one of the most interesting missions that sagan has worked on because of his interests in extraterrestrial life. Pioneer 10 and 11 both carried a very special plaque that both Sagan and Frank Drake created. This plaque was meant as a message to other sentient life in the universe, showing what humans looked like and where the earth is in position to the sun. The plaque also showed where the sun was positioned. Pioneer was sent to explore space and was a scout for the Voyager missions.

Voyager 1 & 2The voyager missions were after the Pioneer missions and were very similar to its precursor. Voyager also explored deep space and the outer planets in the solar system with new discoveries. Voyager 1 and 2 had a very special disk that was similar to the plaque on Pioneer 10 and 11 but could be played. The disk is a golden record and is called Murmurs of Earth on one side and on the other, diagrams and other various information. The diagrams were similar to the Pioneer plaque and with a map to earth to a diagram of the two lowest states of a Hydrogen atom The golden disk bears resemblance to a time capsule, with what we view as important put into the disk. This disk was created by multiple people, a committee, chaired by Carl Sagan hand picked everything that was to be on the disk from the music to the design.
