The National Aeronautics and Space Administration (NASA, /ˈnæsə/) is an independent agency of the United States Federal Government responsible for the civilian space program, as well as aeronautics and aerospace research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA). The new agency was to have a distinctly civilian orientation, encouraging peaceful applications in space science.[7][8][9] Since its establishment, most US space exploration efforts have been led by NASA, including the Apollo Moon landing missions, the Skylab space station, and later the Space Shuttle. NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the Space Launch System and Commercial Crew vehicles. The agency is also responsible for the Launch Services Program which provides oversight of launch operations and countdown management for uncrewed NASA launches. NASA science is focused on better understanding Earth through the Earth Observing System;[10] advancing heliophysics through the efforts of the Science Mission Directorate's Heliophysics Research Program;[11] exploring bodies throughout the Solar System with advanced robotic spacecraft missions such as New Horizons;[12] and researching astrophysics topics, such as the Big Bang, through the Great Observatories and associated programs NASA's ongoing investigations include in-depth surveys of Mars (Mars 2020 and InSight) and Saturn and studies of the Earth and the Sun. Other active spacecraft missions are Juno for Jupiter, New Horizons (for Jupiter, Pluto, and beyond), and Dawn for the asteroid belt. NASA continued to support in situ exploration beyond the asteroid belt, including Pioneer and Voyager traverses into the unexplored trans-Pluto region, and Gas Giant orbiters Galileo (1989–2003), Cassini (1997–2017), and Juno (2011–). The New Horizons mission to Pluto was launched in 2006 and successfully performed a flyby of Pluto on July 14, 2015. The probe received a gravity assist from Jupiter in February 2007, examining some of Jupiter's inner moons and testing on-board instruments during the flyby. On the horizon of NASA's plans is the MAVEN spacecraft as part of the Mars Scout Program to study the atmosphere of Mars.[133] In 2017, President Donald Trump directed NASA to send Humans to Mars by the year 2033.[115][168] Foci in general for NASA were noted as human space exploration, space science, and technology.[168] The Europa Clipper and Mars 2020 continue to be supported for their planned schedules.[169] In 2018, NASA alongside with other companies including Sensor Coating Systems, Pratt & Whitney, Monitor Coating and UTRC have launched the project CAUTION (CoAtings for Ultra High Temperature detectION). This project aims to enhance the temperature range of the Thermal History Coating up to 1,500C and beyond. The final goal of this project is improving the safety of jet engines as well as increasing efficiency and reducing CO2 emissions.[170] The Northrop Grumman Antares rocket, with Cygnus resupply spacecraft on board, launches from Pad-0A, Wednesday, April 17, 2019 at NASA's Wallops Flight Facility in Virginia. Northrop Grumman's 11th contracted cargo resupply mission for NASA to the International Space Station will deliver about 7,600 pounds of science and research, crew supplies and vehicle hardware to the orbital laboratory and its crew.
