Launched by NASA on August 20, 1977, Voyager 2 embarked on an unprecedented journey to explore the outer reaches of our Solar System and beyond. Part of the ambitious Voyager program, it took off 16 days after its sibling, Voyager 1, charting a course that, while slower to reach the gas giants Jupiter and Saturn, allowed it to be the first and only spacecraft to visit the ice giants Uranus and Neptune. Achieving Solar escape velocity as the third of five spacecraft, Voyager 2 is set to exit the Solar System, marking a monumental step in space exploration.
Upon its journey, Voyager 2 meticulously studied the Jovian system in 1979, Saturn’s realm in 1981, ventured through Uranus in 1986, and observed Neptune in 1989, completing its primary mission. Now far beyond the planets it once studied, the spacecraft continues its extended mission, delving into the mysteries of the interstellar medium. As of March 2024, it floats 136.3 AU (20.4 billion km; 12.7 billion mi) from Earth, still in communication and sending invaluable data back to our planet.
Entering the interstellar medium on November 5, 2018, Voyager 2 joined its predecessor in traversing this new frontier, providing critical first-hand observations of the density and temperature outside our solar bubble. Maintained through the NASA Deep Space Network, with significant contributions from Australia’s DSS 43 antenna, this historic mission connects us to the vast unknown.
The genesis of Voyager 2 lies in the realization of a unique planetary alignment in the late 1970s, presenting a golden opportunity for a grand tour of the outer planets, utilizing gravity assists. Evolving from the ambitious Grand Tour to the Mariner Jupiter-Saturn probes, the mission’s scope was adapted to ensure feasibility and cost-effectiveness, laying the groundwork for what would become a journey beyond our wildest dreams.
Voyager 2’s design, a marvel of engineering, features 16 hydrazine thrusters for precise navigation, a suite of scientific instruments for celestial study, and a high-gain antenna ensuring its whispers across the cosmos reach Earth. Powered by three radioisotope thermoelectric generators, it continues to operate far beyond its expected lifespan, a testament to the foresight and ingenuity of its creators.
