Voyager 1 is a historic unmanned space 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 probe that was launched on September 5, 1977, from Cape Canaveral, Florida, as part of the Voyager program. 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, Saturn, and their moons. The primary objectives of the mission were to study the outer Solar System, the heliosphere, and the interstellar medium. Voyager 1 is powered by a radioisotope thermoelectric generator (RTG), which converts the heat generated by the decay of plutonium-238 into electricity. The Voyager spacecraft were designed to be robust and long-lasting, with a minimum design life of five years. However, due to their efficient power source and the lack of atmospheric drag, they have far exceeded their expected lifespan. Voyager 1 is now over 14 billion miles (22.5 billion kilometers) away from Earth, making it the most distant human-made object in space. The spacecraft is still operational, and its instruments continue to send back valuable data about the outer reaches of the Solar System and the interstellar medium. ## History/Background The Voyager program was conceived in the early 1970s, with the goal of sending a spacecraft to the outer planets and studying their moons and rings. The program was led by NASA's Jet Propulsion Laboratory (JPL), with a team of scientists and engineers from across the United States. The Voyager spacecraft were designed and built by a consortium of companies, including NASA's Marshall Space Flight Center, the Jet Propulsion Laboratory, and the California Institute of Technology. Voyager 1 was launched on September 5, 1977, and was followed by Voyager 2, which was launched on August 20, 1977. The two spacecraft were identical, but they followed different trajectories to the outer planets. Voyager 1 flew by Jupiter on March 5, 1979, and Saturn on November 12, 1980. Voyager 2 flew by Jupiter on July 9, 1979, and Saturn on August 25, 1981. After their encounters with Saturn, the spacecraft continued on their journey into interstellar space. ## Key Information Voyager 1 has achieved numerous milestones throughout its mission. It is the most distant human-made object in space, with a distance of over 14 billion miles (22.5 billion kilometers) from Earth. The spacecraft has entered the interstellar medium, the region of space outside of our Solar System. Voyager 1 has also detected the presence of cosmic rays, high-energy particles that originate from outside of our Solar System. The Voyager spacecraft are equipped with a Golden Record, a gold-plated copper record that contains sounds and images of Earth and its inhabitants. The record is intended to serve as a message to any extraterrestrial life form that may encounter the spacecraft. The record contains natural sounds, such as rain and thunder, as well as music from around the world. ## Significance Voyager 1 has had a profound impact on our understanding of the outer Solar System and the interstellar medium. The mission has provided valuable insights into the structure and composition of the outer planets and their moons. The spacecraft has also helped to shed light on the nature of the heliosphere, the region of space influenced by the Sun. The Voyager mission has also raised important questions about the search for extraterrestrial life. The presence of cosmic rays and the detection of organic molecules in the interstellar medium suggest that the conditions for life may exist elsewhere in the universe. The Voyager spacecraft are now a part of the interstellar medium, carrying a message from humanity to the cosmos.
