Voyager 1 is a historic space mission that has traveled farther than any human-made object, providing groundbreaking insights into the outer Solar System and the interstellar medium. ## Overview Launched on September 5, 1977, Voyager 1 is a space probe designed to study the outer Solar System and beyond. The mission was conceived by NASA's Jet Propulsion Laboratory (JPL) as a follow-up to the successful Pioneer 10 and 11 missions. Voyager 1 was built to take advantage of a rare alignment of the outer planets, allowing it to visit Jupiter and Saturn while studying their magnetic fields, atmospheres, and moons. The spacecraft is powered by a radioisotope thermoelectric generator (RTG), which converts the heat generated by the decay of plutonium-238 into electricity. Voyager 1 is equipped with a range of scientific instruments, including a magnetometer, plasma detector, and ultraviolet spectrometer. These instruments have allowed scientists to study the outer Solar System's magnetic fields, charged particles, and composition. The spacecraft's flybys of Jupiter and Saturn provided a wealth of new information about these planets and their moons. Voyager 1's most significant achievement, however, has been its journey into interstellar space, making it the most distant human-made object in space. ## History/Background The Voyager 1 mission was conceived in the early 1970s, when NASA's JPL was tasked with designing a new generation of space probes.
