Voyager 1 is a historic space mission that has traveled farther than any human-made object, providing unparalleled insights into the outer Solar System and interstellar space. ## Overview Voyager 1 is a space probe launched by NASA on September 5, 1977, as part of the Voyager program. The mission was designed to study the outer Solar System and beyond, with a focus on the Jupiter and Saturn systems. The spacecraft was built to withstand the harsh conditions of space, including extreme temperatures, radiation, and the vacuum of interstellar space. Voyager 1 is powered by a radioisotope thermoelectric generator (RTG), which converts the heat generated by the decay of radioactive isotopes into electricity. The Voyager spacecraft are named after the explorers of the 18th century, with Voyager 1 named after the British explorer James Cook's ship, HMS Endeavour's companion ship, the HMS Discovery's companion ship, the HMS Adventure, and the British explorer James Cook's ship, HMS Endeavour. Voyager 1 is a twin spacecraft with Voyager 2, which was launched on August 20, 1977. The two spacecraft were designed to fly by Jupiter and Saturn, while Voyager 1 was also intended to study the outer reaches of the Solar System and the heliosphere, the region of space influenced by the Sun. ## History/Background The Voyager program was conceived in the 1960s as a follow-up to the Mariner 10 mission, which flew by Venus and Mercury. The program was designed to take advantage of a rare alignment of the outer planets, which would allow the spacecraft to fly by Jupiter and Saturn in a single mission. The Voyager spacecraft were built by NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, and were launched from Cape Canaveral Air Force Station in Florida. Voyager 1 was launched on September 5, 1977, and flew by Jupiter on March 5, 1979. The spacecraft's instruments provided a wealth of new information about the planet's atmosphere, magnetic field, and moons. Voyager 1 then flew by Saturn on November 12, 1980, and continued on its journey into the outer Solar System. In 1990, Voyager 1 crossed the heliopause, the boundary between the heliosphere and interstellar space, becoming the first human-made object to enter interstellar space. ## Key Information Voyager 1 has traveled over 14 billion miles (22.5 billion kilometers) from Earth, making it the most distant human-made object in space. The spacecraft is now traveling at a speed of about 38,000 miles per hour (61,155 kilometers per hour), and is about 125 astronomical units (AU) from the Sun. One AU is the average distance between the Earth and the Sun, so Voyager 1 is now about 125 times farther away from the Sun than the Earth. Voyager 1 carries a Golden Record, a gold-plated copper record containing sounds and images of Earth, including natural sounds, music, and human voices. The record is intended to serve as a message to any extraterrestrial life form that might encounter the spacecraft. Voyager 1 also carries a Cosmic Ray System, which is designed to study high-energy particles from outside the Solar System. ## Significance Voyager 1 has provided a wealth of new information about the outer Solar System and interstellar space. The spacecraft's instruments have allowed scientists to study the magnetic fields, atmospheres, and moons of the outer planets, as well as the composition and structure of the interstellar medium. Voyager 1 has also helped scientists to better understand the heliosphere and the boundary between the heliosphere and interstellar space. Voyager 1's journey has also raised important questions about the origins of life in the universe and the possibility of extraterrestrial life. The spacecraft's Golden Record contains a message from humanity, which is intended to serve as a greeting to any extraterrestrial life form that might encounter the spacecraft. Voyager 1's journey has also inspired new generations of scientists and engineers, who are working to develop new technologies and missions to explore the universe.

Voyager 1 is a historic spacecraft that has traveled farther than any human-made object, providing unparalleled insights into the outer Solar System and interstellar space. ## Overview Launched on September 5, 1977, Voyager 1 is a twin spacecraft, along with Voyager 2, designed to study the outer Solar System and beyond. The mission was conceived by NASA's Jet Propulsion Laboratory (JPL) to take advantage of a rare alignment of the outer planets, allowing the spacecraft to visit Jupiter, Saturn, and their moons. Voyager 1's primary objectives were to explore the outer reaches of the Solar System, study the outer planets' magnetospheres, and search for evidence of life beyond Earth. Voyager 1 is a remarkable example of human ingenuity and technological advancement. Weighing approximately 825 kilograms (1,820 pounds), the spacecraft is powered by a radioisotope thermoelectric generator (RTG), which converts the heat generated by the decay of plutonium-238 into electricity. This innovative power source has enabled Voyager 1 to operate for over 45 years, making it one of the longest-operating spacecraft in history. ## History/Background The Voyager program was born out of the success of the Pioneer 10 and 11 missions, which flew by Jupiter and Saturn in the early 1970s. NASA's JPL, led by project manager John Casani, began designing the Voyager spacecraft in the early 1970s. The twin spacecraft were built by NASA's Marshall Space Flight Center in Huntsville, Alabama, and the RTGs were provided by the Los Alamos National Laboratory. Voyager 1's launch on September 5, 1977, marked the beginning of an epic journey that would take the spacecraft farther than any human-made object. ## Key Information Voyager 1's journey has been nothing short of remarkable. After flying by Jupiter in March 1979, the spacecraft encountered Saturn in November 1980. During its Saturn encounter, Voyager 1 discovered the moon of Titan, which has a thick atmosphere and a surface temperature of around -179°C (-285°F). Voyager 1 continued on its trajectory, entering the heliosheath, a region of space where the solar wind slows down, in December 2004. 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's instruments have provided a wealth of information about the outer Solar System and interstellar space. The spacecraft's Cosmic Ray System (CRS) has detected high-energy particles from distant sources, while the Low-Energy Charged Particle (LECP) instrument has studied the solar wind and its interactions with the outer planets' magnetospheres. Voyager 1's Plasma Science (PLS) instrument has measured the density and composition of the interstellar medium, providing insights into the structure and evolution of the Solar System. ## Significance Voyager 1's significance extends far beyond its scientific achievements. The spacecraft has become a symbol of human exploration and a reminder of the vastness and mysteries of the universe. As the most distant human-made object, Voyager 1 has inspired generations of scientists, engineers, and explorers. The spacecraft's Golden Record, a gold-plated copper record containing sounds and images of Earth, serves as a message to any extraterrestrial life form that may encounter the spacecraft.
