** The **Voyager Interstellar Mission** is a historic space exploration project that launched two spacecraft, Voyager 1 and Voyager 2, to study the outer Solar System and beyond, providing humanity with a unique perspective on the cosmos. ## Overview The **Voyager Interstellar Mission** is a groundbreaking space exploration project that has been ongoing for over four decades. Launched in 1977, the mission aimed to study the outer Solar System and beyond, with a focus on the outer planets, their moons, and the interstellar medium. The two spacecraft, Voyager 1 and Voyager 2, were designed to be the most advanced and ambitious space probes of their time, equipped with a suite of instruments to gather data on the composition, magnetic fields, and atmospheres of the planets they encountered. The Voyager spacecraft were built by NASA's Jet Propulsion Laboratory (JPL) and were launched on separate trajectories to take advantage of a rare alignment of the outer planets. Voyager 1 was launched on September 5, 1977, and Voyager 2 was launched on August 20, 1977. Both spacecraft were powered by radioisotope thermoelectric generators (RTGs), which provided a reliable source of energy for the mission. ## History/Background The concept of the Voyager Interstellar Mission dates back to the 1960s, when NASA began planning for a series of space probes to explore the outer Solar System.
