Voyager 1 and 2: Launched in 1977, the twin Voyager spacecraft flew past Jupiter, Saturn, Uranus, and Neptune, providing detailed images and data on these planets and their moons. They also carried the famous Voyager Golden Record, a time capsule of sounds and images from Earth intended to communicate a message of peace and goodwill to any potential extraterrestrial civilizations.
New Horizons: Launched in 2006, the New Horizons spacecraft flew past Pluto and its moons in 2015, providing the first detailed images of this distant world. It has since continued on its journey into the Kuiper Belt, where it has conducted flybys of other icy bodies, such as Arrokoth.
Cassini-Huygens: Launched in 1997, the Cassini spacecraft orbited Saturn for 13 years, providing detailed observations of the planet, its rings, and its moons. The mission also included the Huygens probe, which landed on the surface of Saturn's largest moon, Titan, in 2005.
Juno: Launched in 2011, the Juno spacecraft is currently in orbit around Jupiter, studying the planet's atmosphere, magnetic field, and internal structure. The mission aims to shed light on the formation and evolution of Jupiter and the early solar system.
Europa Clipper: Scheduled to launch in the mid-2020s, the Europa Clipper mission will fly by Jupiter's moon Europa multiple times, studying its icy surface, subsurface ocean, and potential habitability.
These missions have greatly expanded our understanding of the outer solar system and the processes that shape our solar system's evolution. They have also provided new insights into the potential for life beyond Earth, and inspired new questions and avenues for future exploration.
