The NASA Voyager missions were launched in the late 1970s. The unmanned spacecrafts are now on the edge of the solar system and are the most distant human-made objects in the universe. Voyager I carries a golden record and record player with greetings and information about Earth for extraterrestrials. Voyager II also maintains the awe and splendor of late 1970s technology, being equipped with a golden 8-track tape deck and a golden rotary dial telephone with cord.
