** The **Missions Encyclopedia Entry 1783333326** refers to the **New Horizons** spacecraft mission, a historic interplanetary probe that successfully flew by Pluto and the Kuiper Belt, providing groundbreaking insights into the outer reaches of our solar system. **CONTENT:** ### Overview The **New Horizons** mission is a space exploration endeavor launched by NASA in 2006, with the primary objective of exploring the Pluto system and the Kuiper Belt, a region of icy bodies and small celestial objects beyond Neptune. The mission was designed to study the Pluto system in unprecedented detail, including its geology, atmosphere, and moons. The spacecraft was equipped with a suite of advanced instruments, including cameras, spectrometers, and a radio science experiment, to gather data on the Pluto system and its surroundings. New Horizons was launched on January 19, 2006, aboard an Atlas V rocket from Cape Canaveral Air Force Station in Florida. The spacecraft followed a complex trajectory, using a combination of gravity assists from Jupiter and a flyby of Pluto to reach its destination. After a journey of over 9 years and 3 billion miles, New Horizons flew by Pluto on July 14, 2015, at a distance of just 7,800 miles, providing the first close-up images and data on the dwarf planet. ### History/Background The concept of a Pluto mission dates back to the 1990s, when astronomers began to realize that Pluto was not a typical planet, but rather a member of a new class of objects known as dwarf planets. In 2003, NASA selected the **New Horizons** mission as one of its top priorities for the next decade, with a budget of $650 million. The mission was led by Dr. Alan Stern, a renowned planetary scientist and advocate for the exploration of the outer solar system. ### Key Information - **Launch Date:** January 19, 2006 - **Spacecraft Design:** New Horizons is a 1,000-pound (450 kg) spacecraft with a diameter of 7.7 feet (2.3 meters) - **Propulsion:** The spacecraft is powered by a combination of solar panels and a radioisotope thermoelectric generator (RTG) - **Instruments:** New Horizons is equipped with a suite of advanced instruments, including: - **Ralph:** A visible and infrared imaging spectrometer - **LORRI:** A high-resolution camera - **Venetia Burney Student Dust Counter:** A dust counter designed by students - **SWAP:** A solar wind and aurora particle instrument - **Flyby Date:** July 14, 2015 - **Distance:** 7,800 miles (12,500 km) from Pluto's surface ### Significance The **New Horizons** mission has significantly expanded our understanding of the outer solar system, providing the first close-up images and data on Pluto and its moons. The mission has also revealed the diversity of small celestial bodies in the Kuiper Belt, including dwarf planets, asteroids, and comets. The data collected by New Horizons has helped scientists to better understand the formation and evolution of our solar system, as well as the potential for life beyond Earth. **INFOBOX:** - **Name:** New Horizons - **Type:** Interplanetary spacecraft - **Date:** January 19, 2006 (launch) - **Location:** Pluto system and Kuiper Belt - **Known For:** First close-up images and data on Pluto and its moons **TAGS:** New Horizons, Pluto, Kuiper Belt, Space Exploration, Interplanetary Spacecraft, Dwarf Planet, Solar System, NASA, Alan Stern.

** The Voyager 1 spacecraft is a historic interplanetary mission that has become the most distant human-made object in space, providing unparalleled insights into the outer Solar System and beyond. ## Overview Launched on September 5, 1977, Voyager 1 is a twin spacecraft to Voyager 2, designed to study the outer Solar System and beyond. The mission was conceived by NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, with the primary objective of exploring the Jupiter and Saturn systems. Voyager 1 was built to withstand the harsh conditions of space, including extreme temperatures, radiation, and the vacuum of space. The Voyager 1 spacecraft is a remarkable example of human ingenuity and technological advancement. Weighing approximately 825 kilograms (1,820 pounds), the spacecraft measures 3.7 meters (12.1 feet) in length and 1.6 meters (5.2 feet) in diameter. Equipped with a suite of scientific instruments, Voyager 1 has been designed to study the outer Solar System, the heliosphere, and the interstellar medium. The spacecraft's power source is a radioisotope thermoelectric generator (RTG), which converts the heat generated by the decay of radioactive isotopes into electricity. ## History/Background The Voyager 1 mission has its roots in the 1960s, when NASA began planning for a series of interplanetary missions to explore the outer Solar System. The Voyager program was conceived in the early 1970s, with the primary objective of studying the Jupiter and Saturn systems. Voyager 1 was launched on September 5, 1977, from Cape Canaveral Air Force Station in Florida, aboard a Titan IIIE-Centaur rocket. The spacecraft's trajectory was carefully planned to take advantage of the gravitational influence of Jupiter and Saturn, allowing it to reach the outer reaches of the Solar System. ## Key Information Voyager 1 has achieved numerous milestones throughout its journey, including: * **First spacecraft to visit Jupiter**: Voyager 1 flew by Jupiter on March 5, 1979, providing the first close-up images and data about the planet's magnetic field, atmosphere, and moons. * **First spacecraft to visit Saturn**: Voyager 1 flew by Saturn on November 12, 1980, revealing the planet's rings, moons, and magnetic field. * **Most distant human-made object**: Voyager 1 has traveled over 14 billion miles (22.5 billion kilometers) from Earth, making it the most distant human-made object in space. * **Interstellar medium**: Voyager 1 entered the interstellar medium, the region of space outside the Solar System, in August 2012. * **Cosmic ray detection**: Voyager 1 has detected high-energy cosmic rays, providing insights into the origins of these particles. ## Significance The Voyager 1 mission has significantly advanced our understanding of the outer Solar System and the interstellar medium. The spacecraft's data has helped scientists to better understand the formation and evolution of our Solar System, as well as the properties of the interstellar medium. Voyager 1 has also provided a unique opportunity to study the effects of cosmic radiation on electronic components and the long-term stability of spacecraft systems.
