NASA

NASA, the National Aeronautics and Space Administration, is the United States government agency responsible for civil spaceflight, aeronautics research and space and Earth science. Established in 1958 and headquartered in Washington, D.C., it ran the Apollo program that landed the first people on the Moon and now leads the Artemis campaign to return to the lunar surface.

History of NASA

NASA was formed in response to early Soviet space achievements. It was built on the National Advisory Committee for Aeronautics, known as NACA, which had been the center of United States civil aerospace research and development. NACA research included high-speed flight work with aircraft such as the D-558-2 Skyrocket, photographed at the High-Speed Flight Station at Edwards Air Force Base in January 1954. The agency lists 29 July 1958 as its founding date and began operating on 1 October 1958.

The creation of NASA followed the Sputnik launch of 1957, which pushed the United States to speed up its own satellite work. After the Vanguard rocket exploded on its launch pad, the first American satellite, Explorer, reached orbit on 31 January 1958.

President John F. Kennedy set NASA a goal on 25 May 1961: to perform a crewed lunar landing and return to Earth. Apollo 8 made the first crewed trip to the vicinity of the Moon in December 1968. On the Apollo 11 mission, launched on 16 July 1969, Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon while Michael Collins stayed in orbit, and the crew splashed down on 24 July 1969.

The decades after Apollo brought long-lived scientific and international projects. The Hubble Space Telescope launched on 24 April 1990, and the International Space Station, launched in 1998, involves the United States, Russia, Canada, Japan and the participating countries of the European Space Agency. NASA counts 259 spacewalks at the station since December 1998.

Structure and organization of NASA

As of November 2026, NASA describes itself as organized into four Mission Directorates: Research and Technology, Human Spaceflight, Science and Mission Support. The Human Spaceflight directorate leads human spaceflight and space-enabling activity in low Earth orbit, around the Moon and beyond. The Science directorate leads flagship scientific missions that study the universe, search for life elsewhere and improve understanding of Earth.

NASA carries out its work at 20 centers and facilities across the country, together with commercial companies and international partners. They include Ames Research Center, Armstrong Flight Research Center, Glenn Research Center, Goddard Space Flight Center, the Jet Propulsion Laboratory, Johnson Space Center, Kennedy Space Center, Langley Research Center and Marshall Space Flight Center. The Research and Technology directorate works with the Department of Energy on capabilities such as nuclear electric propulsion, which NASA calls key to future missions to Mars and beyond. The associate administrator, the highest-ranking civil servant at the agency, leads its 10 center directors and the heads of the mission directorates at headquarters in Washington.

NASA is led by an administrator. The agency lists Jared Isaacman as its 15th administrator and Matt Anderson as deputy administrator.

What NASA does

NASA’s work covers four broad areas: human exploration of space, robotic science missions, aeronautics and technology development. It studies Earth science, including climate, along with the Sun, the solar system and the wider universe. It also develops technology to improve air transport.

Its flagship programs include the International Space Station, the world’s leading orbiting laboratory, and the Artemis campaign, which aims to establish a sustained exploration presence on the Moon this decade. Robotic missions include Mars rover missions, one of which was joined by the Ingenuity helicopter in 2021.

The agency also supports commercial spaceflight. NASA, Roscosmos, SpaceX and Boeing have all launched crews to the space station on their own vehicles. Hubble has changed scientific understanding of the universe, from the makeup of planets around other stars to the discovery of dark energy, according to NASA.

Sharing information is a stated duty. The founding legislation called for the widest practicable and appropriate spread of information about NASA activities and their results, and the agency describes preserving and opening its own history to the public as a priority.

Governance and funding of NASA

Federal law establishes NASA under 51 U.S. Code Section 20111. The agency is headed by an administrator appointed from civilian life by the President with the advice and consent of the Senate. Under the supervision and direction of the President, the administrator is responsible for exercising all powers and duties of the agency and has authority and control over all its personnel and activities. A deputy administrator is appointed in the same way.

In a 2008 law marking the agency’s 50th anniversary, Congress stated that NASA is and should remain a multimission agency with core missions in science, aeronautics and human space flight and exploration. That statement still frames the balance the agency is expected to keep among its programs.

NASA is a federal agency, and it publishes its annual budget requests and agency financial reports online. Its fiscal year 2027 budget request documents, including a full request and a summary, appeared in April 2026. This entry does not give a budget total, since the figure depends on what Congress appropriates in a given year.

Impact and legacy of NASA

NASA’s greatest public legacy is the Apollo program, which met the goal set in 1961 within the decade, in the middle of the Cold War rivalry with the Soviet Union. NASA now works with space agencies in Europe, Canada, Japan and Russia on the International Space Station.

Its science missions have also reshaped knowledge of the cosmos. A space telescope such as Hubble sees without the blurring effect of Earth’s atmosphere, and the data it has gathered since 1990 has fed research on planets around other stars and on dark energy.

The agency also acts as a research partner for universities and industry, running programs for students and educators and publishing mission data. Its mix of exploration, science and aeronautics research makes it one of the most visible public institutions in the United States.
