Missions Encyclopedia Entry 1777718644: Voyager 1
SUMMARY: 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
Launched on September 5, 1977, Voyager 1 is a twin spacecraft mission designed to study the outer Solar System and beyond. The mission was conceived to take advantage of a rare alignment of the outer planets, allowing the spacecraft to visit Jupiter and Saturn while studying the heliosphere, the region of space influenced by the Sun. Voyager 1 is one of the most ambitious and successful space missions in history, having traveled over 14 billion miles (22.5 billion kilometers) from Earth.
The Voyager 1 spacecraft is a marvel of engineering, weighing approximately 1,580 pounds (716 kilograms) and measuring 7.5 feet (2.3 meters) in length. It is powered by a radioisotope thermoelectric generator (RTG), which converts the heat generated by the decay of radioactive isotopes into electricity. The spacecraft is equipped with a range of scientific instruments, including a plasma science instrument, a low-energy charged particle instrument, and a cosmic ray system.
History/Background
The Voyager 1 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 1 spacecraft was designed and built by a team of scientists and engineers at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. The mission was launched on September 5, 1977, from Cape Canaveral Air Force Station in Florida, aboard a Titan IIIE-Centaur rocket.
Voyager 1's primary mission was to study the outer Solar System, with a focus on the Jupiter and Saturn systems. The spacecraft flew by Jupiter on March 5, 1979, and by Saturn on November 12, 1980. During these encounters, Voyager 1 sent back a wealth of data and images, including the famous "Pioneer Holes" image of Jupiter's magnetic field and the stunning "Saturn's Rings" image.
