Voyager 1 is a space exploration mission launched by NASA in 1977, designed to study the outer Solar System and beyond, and is now the most distant human-made object in space. ## Overview Voyager 1 is a space exploration mission that was launched on September 5, 1977, by NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. The mission was designed to study the outer Solar System, particularly the gas giants Jupiter and Saturn, and to explore the outer reaches of the heliosphere, the region of space influenced by the Sun. Voyager 1 is one of two identical spacecraft, the other being Voyager 2, which was launched on August 20, 1977. The Voyager spacecraft were designed to be flybys, meaning they would pass close to their targets and then continue on their journey into interstellar space. The Voyager spacecraft are powered by radioisotope thermoelectric generators (RTGs), which convert the heat generated by the decay of radioactive isotopes into electricity. This power source allows the spacecraft to continue operating long after their primary mission has been completed. Voyager 1 is equipped with a range of scientific instruments, including a magnetometer, a plasma spectrometer, and a cosmic ray detector, which are used to study the magnetic fields, plasma, and cosmic rays in the outer Solar System. ## History/Background The Voyager mission was conceived in the early 1970s, as a follow-up to the Pioneer 10 and 11 missions, which had explored the outer Solar System in the early 1970s. The Voyager spacecraft were designed to take advantage of a rare alignment of the outer planets, which would allow them to visit Jupiter and Saturn in a single mission. The Voyager spacecraft were built by NASA's Jet Propulsion Laboratory (JPL) and were launched in 1977, with Voyager 1 departing on September 5 and Voyager 2 departing on August 20. The Voyager spacecraft flew by Jupiter in March 1979 and Saturn in November 1980, providing a wealth of new information about the gas giants and their moons. After their flybys, the Voyager spacecraft continued on their journey into interstellar space, becoming the most distant human-made objects in space. ## Key Information Voyager 1 has achieved several notable milestones in its journey. On August 25, 2012, Voyager 1 crossed the heliopause, the boundary between the heliosphere and interstellar space, becoming the first human-made object to enter interstellar space. Voyager 1 is now about 14.2 billion miles (22.8 billion kilometers) away from Earth, or about 125 AU (astronomical units) from the Sun. Voyager 1 is equipped with a Golden Record, a gold-plated copper record that contains sounds and images of Earth, as well as a message from humanity. The Golden Record is intended to serve as a message to any extraterrestrial life form that may encounter the spacecraft. ## Significance Voyager 1 has greatly expanded our understanding of the outer Solar System and the heliosphere. The spacecraft has provided a wealth of new information about the magnetic fields, plasma, and cosmic rays in the outer Solar System, and has helped scientists to better understand the formation and evolution of the Solar System. Voyager 1 has also served as a technological demonstration of the capabilities of space exploration. The spacecraft has operated for over 40 years, far exceeding its original design lifespan, and has continued to provide valuable scientific data long after its primary mission has been completed.
