** The **Missions Encyclopedia Entry 1777949777** refers to the **New Horizons** spacecraft mission, a historic flyby of the dwarf planet **Pluto** and its moons, providing groundbreaking insights into the Kuiper Belt region. ## Overview Launched on January 19, 2006, **New Horizons** is a space exploration mission designed to study the **Kuiper Belt**, a region of icy bodies and small celestial objects beyond the orbit of **Neptune**. The mission is a collaborative effort between NASA and the Johns Hopkins University Applied Physics Laboratory (APL). **New Horizons** is equipped with a suite of scientific instruments, including cameras, spectrometers, and a radio science experiment, to gather data on the composition, geology, and atmosphere of **Pluto** and its moons. The **New Horizons** spacecraft is powered by a radioisotope thermoelectric generator (RTG), which converts the heat generated by the decay of radioactive isotopes into electricity. This unique power source allows the spacecraft to operate for extended periods, making it an ideal choice for long-duration missions. The spacecraft's design also features a high-gain antenna, a digital computer, and a data storage system, enabling it to transmit data back to Earth. ## History/Background The concept of a **Pluto** flyby mission dates back to the 1990s, when astronomers began to realize the importance of studying the dwarf planet and its moons. In 2003, NASA selected the **New Horizons** mission proposal, led by Dr. Alan Stern, as the winner of the **New Frontiers** program. The mission was initially planned to fly by **Pluto** in 2015, but the launch date was later moved up to 2006 to take advantage of a favorable alignment of the **Pluto** system and the Earth. ## Key Information **New Horizons** flew by **Pluto** on July 14, 2015, at a distance of approximately 7,800 miles (12,500 kilometers). The spacecraft's instruments gathered an unprecedented amount of data on the dwarf planet's surface, atmosphere, and moons. Some of the key findings include: * **Pluto**'s surface is composed primarily of nitrogen ice, with evidence of recent geological activity. * The dwarf planet's atmosphere is composed mostly of nitrogen gas, with a thin layer of methane ice. * **Pluto**'s moons, including **Charon**, **Nix**, **Hydra**, and **Kerberos**, are thought to have formed through a process of gravitational capture. * The **New Horizons** spacecraft detected a possible subsurface ocean on **Pluto**, which could potentially harbor life. ## Significance The **New Horizons** mission has significantly expanded our understanding of the **Kuiper Belt** region and the dwarf planet **Pluto**. The mission has also provided valuable insights into the formation and evolution of our solar system. The discovery of a possible subsurface ocean on **Pluto** has implications for the search for life beyond Earth. **INFOBOX:** - **Name:** New Horizons - **Type:** Spacecraft mission - **Date:** January 19, 2006 (launch) - **Location:** Kuiper Belt region - **Known For:** Historic flyby of **Pluto** and its moons **TAGS:** **New Horizons**, **Pluto**, **Kuiper Belt**, **Space Exploration**, **NASA**, **Johns Hopkins University Applied Physics Laboratory**, **Astronomy**, **Astrophysics**, **Dwarf Planet**, **Spacecraft Mission**

** The **New Horizons** mission is a groundbreaking interplanetary space probe launched by NASA in 2006, designed to explore the **Kuiper Belt**, a region of icy bodies and other small celestial objects beyond Neptune's orbit. **CONTENT:** ## Overview The **New Horizons** mission is a pioneering space exploration project that has greatly expanded our understanding of the **Kuiper Belt** and the **Dwarf Planet Pluto**. Launched on January 19, 2006, from Cape Canaveral Air Force Station in Florida, the spacecraft was built by **Aerospace Corporation** and operated by **Johns Hopkins University Applied Physics Laboratory**. The primary objective of the mission was to study the Pluto system, including its moons, atmosphere, and surface composition. The spacecraft's journey took nearly nine and a half years, with the flyby of Pluto occurring on July 14, 2015. ## History/Background The concept of exploring the **Kuiper Belt** dates back to the 1990s, when astronomers began to recognize the importance of this region in understanding the formation and evolution of our solar system. The **New Horizons** mission was formally approved in 2003, with a launch window between January and March 2006. The spacecraft was designed to take advantage of a rare alignment of the planets, which would allow it to use the gravity of Jupiter to accelerate its trajectory and reach the **Kuiper Belt** in a relatively short period. The mission's development was marked by several challenges, including the need to design a spacecraft that could withstand the harsh conditions of interplanetary space and the complexities of navigating through the **Kuiper Belt**. ## Key Information The **New Horizons** spacecraft is equipped with a range of scientific instruments, including a **Multispectral Visible Imaging Camera (MVIC)**, an **Alice Ultraviolet Spectrometer**, and a **Radio Science Experiment (RSE)**. During its flyby of Pluto, the spacecraft collected a vast amount of data, including high-resolution images of the dwarf planet's surface, its moons, and its atmosphere. The mission's findings have greatly expanded our understanding of the **Kuiper Belt** and its inhabitants, including the discovery of a heart-shaped region on Pluto's surface, known as the **Sputnik Planum**. The spacecraft has also provided valuable insights into the geology and composition of Pluto's moons, including **Charon**, **Nix**, and **Hydra**. ## Significance The **New Horizons** mission has had a profound impact on our understanding of the **Kuiper Belt** and the **Dwarf Planet Pluto**. The mission's findings have challenged our previous assumptions about the formation and evolution of our solar system and have provided new insights into the processes that shape the surfaces of small celestial bodies. The mission's success has also paved the way for future exploration of the **Kuiper Belt**, including the **Artemis** mission, which aims to send a spacecraft to the **Kuiper Belt** in the 2020s. The **New Horizons** mission has also inspired a new generation of scientists and engineers, who are working to push the boundaries of space exploration and to expand our understanding of the universe. **INFOBOX:** - Name: **New Horizons** - Type: **Interplanetary Space Probe** - Date: **January 19, 2006** - Location: **Kuiper Belt** - Known For: **First Flyby of Pluto** **TAGS:** **Kuiper Belt**, **Dwarf Planet Pluto**, **New Horizons**, **Space Exploration**, **Interplanetary Space Probe**, **Astronomy**, **Astrophysics**, **Spacecraft**, **NASA**, **Johns Hopkins University Applied Physics Laboratory**
