Voyager 1 is a historic unmanned space mission launched by NASA in 1977, designed to study the outer Solar System and beyond, becoming the most distant human-made object in space. ## Overview Voyager 1 is a space probe that was launched on September 5, 1977, from Cape Canaveral Air Force Station in Florida, USA. The mission was designed to take advantage of a rare alignment of the outer planets in our Solar System, allowing the spacecraft to visit Jupiter and Saturn in a single mission. Voyager 1 was built by NASA's Jet Propulsion Laboratory (JPL) and was the first spacecraft to visit Jupiter and Saturn, providing a wealth of information about these gas giants and their moons. The Voyager 1 spacecraft is a remarkable achievement in engineering and design, weighing approximately 825 kilograms (1,820 pounds) and measuring 3.7 meters (12.1 feet) in length. The spacecraft is powered by a radioisotope thermoelectric generator (RTG), which converts the heat generated by the decay of radioactive isotopes into electricity. This power source has allowed Voyager 1 to continue operating for over 45 years, making it one of the longest-operating spacecraft in history. ## History/Background The Voyager 1 mission was conceived in the early 1970s, when NASA's Planetary Program was looking for a way to take advantage of the rare alignment of the outer planets. The mission was initially designed to visit Jupiter and Saturn, but it was later expanded to include a flyby of Uranus and Neptune. The Voyager 1 spacecraft was launched on September 5, 1977, and it began its journey to the outer Solar System. Voyager 1's first major milestone was its encounter with Jupiter on March 5, 1979. The spacecraft flew within 350,000 kilometers (217,000 miles) of Jupiter's cloud tops, providing stunning images and valuable data about the planet's atmosphere and magnetic field. Voyager 1 then continued on its journey to Saturn, which it encountered on November 12, 1980. The spacecraft flew within 124,000 kilometers (77,000 miles) of Saturn's cloud tops, providing a wealth of information about the planet's rings and moons. ## Key Information Voyager 1 has achieved many notable milestones during its journey.

Voyager 1 is a space probe launched by NASA in 1977, designed to study the outer Solar System and beyond, becoming the most distant human-made object in space. ## Overview Voyager 1 is a space exploration mission that has been in operation for over 45 years, making it one of the longest-running space missions in history. Launched on September 5, 1977, from Cape Canaveral, Florida, Voyager 1 was designed to study the outer Solar System, including the gas giants Jupiter and Saturn, and to explore the outer reaches of the heliosphere, the region of space influenced by the Sun. The spacecraft was built by NASA's Jet Propulsion Laboratory (JPL) and is powered by a radioisotope thermoelectric generator (RTG), which converts the heat generated by the decay of radioactive isotopes into electricity. Voyager 1 is a twin mission to Voyager 2, which was launched on August 20, 1977. While both spacecraft were designed to explore the outer Solar System, Voyager 1 was sent on a more northerly trajectory, which allowed it to fly by Jupiter and Saturn at a more favorable angle. This decision was made to take advantage of the gravitational assist provided by Jupiter's massive size and proximity to the Sun, which would allow Voyager 1 to gain speed and alter its trajectory. ## History/Background The Voyager 1 mission was conceived in the early 1970s, when NASA was planning a series of space missions to explore the outer Solar System. The Voyager program was designed to study the outer planets and their moons, as well as the outer reaches of the heliosphere. The mission was also intended to search for signs of life beyond Earth and to study the interstellar medium, the material that fills the space between stars. Voyager 1 was launched on September 5, 1977, aboard a Titan IIIE rocket, which placed the spacecraft into a heliocentric orbit. The spacecraft's journey to Jupiter took approximately 5 years, during which time it was powered down to conserve energy and was reactivated only when it approached the planet. Voyager 1 flew by Jupiter on March 5, 1979, and then by Saturn on November 12, 1980. ## Key Information Voyager 1 has achieved numerous milestones throughout its mission, including: * **First spacecraft to visit Jupiter and Saturn**: Voyager 1 was the first spacecraft to fly by both Jupiter and Saturn, providing scientists with a wealth of information about these gas giants and their moons. * **Most distant human-made object**: Voyager 1 is the most distant human-made object in space, with a distance of over 14 billion miles (22.5 billion kilometers) from Earth. * **Interstellar space**: Voyager 1 entered interstellar space in August 2012, becoming the first spacecraft to do so. * **Pioneer plaque**: Voyager 1 carries a gold-plated copper record, known as the Golden Record, which contains sounds and images of Earth and its inhabitants. * **Power source**: Voyager 1 is powered by a radioisotope thermoelectric generator (RTG), which has provided the spacecraft with a reliable source of energy for over 45 years. ## Significance Voyager 1 has had a profound impact on our understanding of the outer Solar System and the universe beyond.
