The Voyager spacecraft are two robotic probes, Voyager 1 and Voyager 2, launched by NASA in 1977. Their primary mission was to explore the outer planets of our solar system, including Jupiter, Saturn, Uranus, and Neptune. Both spacecraft provided valuable data and stunning images, significantly enhancing our understanding of these distant worlds. After completing their primary missions, the Voyager spacecraft continued to travel into interstellar space. They are now the farthest human-made objects from Earth, sending back data about cosmic rays and the solar wind. The mission has greatly contributed to our knowledge of the heliosphere and the boundaries of our solar system.
