Even prehistoric cave art in many cases contains evidence of human curiosity about the cosmos. On the other hand space travel is an extremely new phenomenon for us here on planet Earth cosmically speaking. NASA’s Voyager program is one of the most important instances of space exploration in the long history of that very ancient human desire.When NASA sent Voyager 1 and Voyager 2 out in the 1970s the mission Belize WhatsApp Number was simple explore Jupiter Saturn and the moons of those two planets. The probes were originally designed to last just five years. And yet today 45 years after they were launched they’re still hurtling through interstellar space at a greater distance than human-made objects have ever been from Earth. How is that possible and why is it importantThe Amazing Optimism of Voyager and the Golden RecordDespite the initial plan to explore just Jupiter and Saturn the folks who planned the Voyager mission did have larger goals than that in mind.

For one thing four planets — Jupiter Saturn Uranus and Neptune — were in an alignment that only happens once every 175 years allowing for the possibility of low-energy travel to those planets by the Voyagers. Eventually scientists hoped that the twin probes would be able to explore the outer reaches of the solar system.However there was another part of the Voyager project that was even more optimistic than the hope of exploring interstellar space. A committee chaired by the famous astronomer and science communicator Carl Sagan put together a special golden phonograph record that was affixed to each of the
