NASA — National Aeronautics and Space Administration

The world's largest and most capable space agency — from the Apollo Moon landings and the Space Shuttle to the Artemis lunar return, Mars rovers and the James Webb Space Telescope.

NASA stands for the National Aeronautics and Space Administration — the United States government's civil space agency, founded in 1958. It leads the Artemis lunar programme, operates half the International Space Station and runs the largest space science fleet of any agency, on a budget of about $25 billion a year.

NASA is the United States' civil space agency, established by President Eisenhower in 1958 in response to the Soviet Union's Sputnik satellite. Over six decades, NASA has defined the frontier of human achievement in space — landing twelve astronauts on the Moon during the Apollo programme (1969–1972), operating the Space Shuttle fleet for 30 years (1981–2011), building the International Space Station, and sending robotic explorers to every planet in the solar system.

Today NASA manages a $25+ billion annual budget across four mission directorates: Exploration Systems (Artemis, Gateway, Commercial Crew), Science (JWST, Mars rovers, Earth observation), Space Technology, and Aeronautics. NASA does not launch its own rockets for most missions — instead partnering with commercial providers like SpaceX (Falcon 9, Dragon, Starship) and ULA (Atlas V, Vulcan Centaur) under fixed-price contracts, a model that has dramatically reduced launch costs.

Key Programmes

Artemis Programme

NASA's flagship effort to return astronauts to the Moon. Artemis I (uncrewed, 2022) successfully tested the SLS rocket and Orion capsule. Artemis II will carry crew around the Moon. Artemis III aims to land the first woman and first person of colour on the lunar surface using SpaceX's Starship as the Human Landing System.

International Space Station

NASA is the primary operator and funder of the ISS, continuously inhabited since November 2000. Commercial Crew missions aboard SpaceX Dragon transport NASA astronauts to and from the station. The ISS is expected to operate until 2030, after which NASA plans to transition to commercially operated stations.

Mars Exploration

NASA operates the Perseverance rover and Ingenuity helicopter on Mars (landed February 2021). The Mars Sample Return mission — a joint effort with ESA — aims to bring Perseverance's collected rock samples back to Earth. Curiosity rover continues operating in Gale Crater since 2012.

James Webb Space Telescope

Launched December 2021, JWST orbits the Sun at the L2 Lagrange point with a 6.5-metre gold-coated mirror observing in infrared. It has transformed understanding of exoplanet atmospheres, early galaxies and star formation — the most powerful telescope ever built.

Commercial Crew & Cargo

NASA's partnerships with SpaceX (Dragon) and Boeing (Starliner) for ISS crew transport, replacing the Shuttle. SpaceX has completed 15+ operational crew missions. NASA also funds commercial cargo via SpaceX Dragon and Northrop Grumman Cygnus.

Earth Science

NASA operates dozens of Earth observation satellites monitoring climate change, weather, sea level, ice sheets and atmospheric composition. Key missions include Landsat (50+ year record), PACE (ocean colour), NISAR (surface deformation, with ISRO) and the Earth System Observatory.

NASA — frequently asked questions

What does NASA stand for?

NASA stands for the National Aeronautics and Space Administration. It is the civil space agency of the United States government, established on 29 July 1958, with headquarters in Washington, D.C.

What is NASA's budget?

NASA's enacted budget for fiscal year 2025 was about $25.4 billion — the largest of any space agency. The White House's FY2026 request proposed a cut of roughly a quarter, to about $18.8 billion; the final figure rests with Congress. For comparison, China's space programme is estimated at around $14 billion and ESA's at about €7.8 billion.

Is NASA the biggest space agency in the world?

Yes, by budget and overall capability. NASA spends more than any other space agency, operates crewed spacecraft, deep-space missions and the largest science fleet. By annual launch count, however, China's state programme now conducts more orbital launches per year.

How many satellites does NASA operate?

Orbital Radar counts NASA's own tracked science and research spacecraft live from the satellite catalogue — the figure on this page updates daily. This excludes US commercial constellations such as Starlink, and NOAA and military satellites, which are operated by other US bodies.
