NASA has launched both the voyager missions into space 40 years ago to explore the extraterrestrial life beyond our planet. These two voyagers are the only working mission that are still transmitting the signals to earth and also the only man made satellites that traveled the longest space and still continuing their journey to the interstellar space.
These two twin missions used the sling shot trajectory with less computing power than a cell phone to visit Jupiter, Saturn, Neptune, Uranus. The images sent back has revolutionized the understanding of the outer world and planets and changed the phase of Space science that led to further missions to explore the planets and their moons.
These mission are still sailing on their way to outer space and may be the only missions that could be still traveling even after the human race extinction as a proof to the aliens that human race existed. It carries the golden record with greetings, music and images from earth.
NASA is celebrating the 40th anniversary with most beautiful designs and free posters to download. You can download it from here.
