New Horizons is an interplanetary space probe launched as a part of NASA's New Frontiers program. Engineered by the Johns Hopkins University Applied Physics Laboratory (APL) and the Southwest Research Institute (SwRI), with a team led by Alan Stern, the spacecraft was launched in 2006 with the primary mission to perform a flyby study of the Pluto system in 2015, and a secondary mission to fly by and study one or more other Kuiper belt objects (KBOs) in the decade to follow, which became a mission to 486958 Arrokoth. It is the fifth space probe to achieve the escape velocity needed to leave the Solar System.

132524 APL (provisional designation 2002 JF56) is a small background asteroid in the intermediate asteroid belt. It was discovered by Lincoln Near-Earth Asteroid Research in May 2002, and imaged by the New Horizons space probe on its flyby in June 2006, when it was passing through the asteroid belt. The stony S-type asteroid measures approximately 2.5 kilometers (1.6 miles) in diameter.
Stamatios (Tom) Mike Krimizis is a Greek-American scientist in space exploration. He has contributed to many of the United States' unmanned space exploration programs of the Solar System and beyond. He has contributed to exploration missions to almost every planet of the Solar System. In 1999, the International Astronomical Union named the asteroid 8323 Krimigis in his honor.
The exploration of Pluto began with the arrival of the New Horizons probe in July 2015, though proposals for such a mission had been studied for many decades. There are no plans as yet for a follow-up mission, though follow-up concepts have been studied.
Kerberos is a small natural satellite of Pluto, about 19 km (12 mi) in its longest dimension. Kerberos is also the second-smallest moon of Pluto, after Styx. It was the fourth moon of Pluto to be discovered and its existence was announced on 20 July 2011. It was imaged, along with Pluto and its four other moons, by the New Horizons spacecraft in July 2015. The first image of Kerberos from the flyby was released to the public on 22 October 2015.

Dr. Colleen Hartman is currently the Board Director for the Space Studies Board as well as the Aeronautics and Space Engineering Board of the National Academies of Sciences, Engineering, and Medicine in Washington, D.C. She was the deputy center director for Science, Operations and Performance of NASA’s Goddard Space Flight Center and most recently, was the Director of the Science and Exploration Directorate. Previously she was acting Associate Administrator of the Science Mission Directorate (SMD), Deputy AA of SMD and presidential management intern, served as a senior policy analyst at the White House Office of Science and Technology Policy, and served as deputy division director for technology at NASA Headquarters.
486958 Arrokoth (provisional designation 2014 MU69; formerly nicknamed Ultima Thule) is a trans-Neptunian object located in the Kuiper belt. Arrokoth became the farthest and most primitive object in the Solar System visited by a spacecraft when the NASA space probe New Horizons conducted a flyby on 1 January 2019. Arrokoth is a contact binary 36 km (22 mi) long, composed of two planetesimals 21 and 15 km (13 and 9 mi) across, that are joined along their major axes. With an orbital period of about 298 years and a low orbital inclination and eccentricity, Arrokoth is classified as a cold classical Kuiper belt object.
2014 MT69 (internally designated 0720090F in the context of the Hubble Space Telescope, and 7 in the context of the New Horizons mission) is a cold classical Kuiper belt object (KBO) and was formerly a potential flyby target for the New Horizons probe. The object measures approximately 20–90 kilometers (12–56 miles) in diameter.
Lisa Hardaway (1966–2017) was an American aerospace engineer and program manager for an instrument on the New Horizons spacecraft to Pluto and Beyond. Among her awards, she was named Engineer of the Year for 2015–2016 by the Colorado American Institute of Aeronautics and Astronautics.
The Planetary Missions Program Office is a division of NASA headquartered at the Marshall Space Flight Center, formed by the agency's Science Mission Directorate (SMD). Succeeding the Discovery and New Frontiers Program Office, it was established in 2014 to manage the Discovery and New Frontiers programs of low and medium-cost missions by third-party institutions, and the Solar System Exploration program of NASA-led missions that focus on prioritized planetary science objectives. The Discovery and New Frontiers programs were established in 1992 and 2001 respectively, and have launched fourteen primary missions together, along with two missions launched under the administration of the Planetary Missions Program Office. The Solar System Exploration Program was established alongside the office, with three missions planned for launch under the new program.
Ralph is a science instrument aboard the robotic New Horizons spacecraft, which was launched in 2006. Ralph is a visible and infrared imager and spectrometer to provide maps of relevant astronomical targets based on data from that hardware. Ralph has two major subinstruments, LEISA and MVIC. MVIC stands for Multispectral Visible Imaging Camera and is a color imaging device, while LEISA originally stood for Linear Etalon Imaging Spectral Array and is an infrared imaging spectrometer for spaceflight. LEISA observes 250 discrete wavelengths of infrared light from 1.25 to 2.5 micrometers. MVIC is a pushbroom scanner type of design with seven channels, including red, blue, near-infrared (NIR), and methane.
Hibernation of spacecraft is an operating mode used when regular operations are suspended for an extended period of time but restarting is expected. On long duration and deep space missions it saves power or other limited resources and extends mission life. The term is substantially similar to the hibernation mode used in computer power saving.
Kelsi N. Singer (born 1984) is an American planetary scientist who is a senior research scientist at the Southwest Research Institute (SwRI) in Boulder, CO. She is a co-investigator and deputy project scientist of NASA's New Horizons mission studying the geomorphology and geophysics of the Pluto system and of Arrokoth (2014 MU69).
Interstellar Probe (ISP) is a proposed NASA space probe designed to explore and characterize the heliosphere and interstellar space. The study was originally proposed in 2018 by NASA for the Applied Physics Laboratory. It would have a baseline launch between 2036 and 2041. The probe would launch on a direct hyperbolic trajectory to encounter Jupiter after six to seven months, after which the probe would travel at a speed of about 6–7 astronomical units (900,000,000–1.05×109 kilometres) per year, leaving the heliosphere after only 16 years.
Timeline for the New Horizons interplanetary space probe lists the significant events of the launch, transition phases as well as subsequent significant operational mission events; by date and brief description.
The exploration of dwarf planets involves studying these celestial bodies within the Solar System. Since Pluto's reclassification as a dwarf planet in 2006 by the International Astronomical Union (IAU), space exploration has increasingly focused on these celestial bodies.
