For millennia, humans have gazed at the night sky, drawing wonder from the first recorded observation on the 1600 B.C. bronze Nebra sky disk, which depicted the Sun, crescent moon, and stars. This early fascination laid the groundwork for the modern age of exploration, culminating in the establishment of NASA—the National Aeronautics and Space Administration.
As a federal agency, NASA operates 20 research and test facilities and visitor centers across the United States. With a workforce of more than 18,000 employees and contractors, its core mandate is to study the unknown in the air and outer space. NASA leads cutting‑edge Earth‑science research while also probing the Sun, planets, and the wider cosmos through radio telescopes, rovers, probes, and spacecraft. A flagship example is the 2021 launch of the James Webb Space Telescope, which orbits the Sun and delivers unprecedented data—such as the discovery of water beyond Earth—to astronomers worldwide. The agency also conducts experiments aboard the International Space Station and is gearing up for the Artemis program, which will bring humans back to the Moon.
Beyond exploration, NASA pushes the boundaries of aeronautics and technology, delivering innovations that benefit society. It openly shares its findings, collaborates with educators to train future astronauts, engineers, and scientists, and offers hands‑on opportunities that inspire students to engage with space missions.

NASA was founded in 1958, not as the first U.S. space program but as the civilian successor to various military aerospace initiatives. President Dwight D. Eisenhower signed the National Aeronautics and Space Act, separating civil research from the military and creating an agency to coordinate non‑military space activities. The launch of Sputnik in 1957 spurred this effort, prompting the United States to keep pace with Soviet achievements.
NASA’s early triumphs include Project Mercury, which conducted six manned flights between 1961 and 1963 to test human spaceflight viability. The Apollo era followed, with Apollo 11’s Neil Armstrong and Buzz Aldrin becoming the first humans to walk on the Moon in 1969. These milestones were part of a broader legacy that saw the first U.S. space station, Skylab, in 1973 and the International Space Station (ISS) in 1993—a multinational collaboration involving 15 countries. The Space Shuttle Program proved the world’s first reusable spacecraft, while the Hubble Space Telescope, launched in 1990, has made more than 1.3 million observations of the universe. In 2012, NASA partnered with private company SpaceX for the first commercial resupply mission to the ISS, marking a new era of public‑private cooperation in space.
