The National Aeronautics and Space Administration (NASA) is an independent agency of the United States federal government responsible for the civil space program, aeronautics research, and space exploration. Established on July 29, 1958, under the National Aeronautics and Space Act of 1958, it replaced the National Advisory Committee for Aeronautics (NACA). Its creation was a strategic response to the Soviet Union’s launch of Sputnik 1 in 1957, signaling the start of the "Space Race."
NASA operates as a civilian entity, emphasizing peaceful applications in space science. Key features include its leadership in landmark missions like the Apollo Moon landings, the International Space Station (ISS), and the Artemis program, which aims to establish a sustainable human presence on the Moon. It manages advanced observatories like the James Webb Space Telescope (JWST) and planetary missions such as the Perseverance Rover on Mars.
For the UPSC exam, NASA is significant under GS Paper III (Science and Technology) and GS Paper II (International Relations). It is central to India-US bilateral cooperation, specifically through the NASA-ISRO Synthetic Aperture Radar (NISAR) mission—a joint Earth-observing mission—and the Artemis Accords, which India signed in 2023. Related concepts include the Outer Space Treaty of 1967, the Inter-Agency Space Debris Coordination Committee (IADC), and the rise of the NewSpace private sector. Understanding NASA’s technological milestones is crucial for Prelims, while its role in Space Diplomacy and the governance of the "Global Commons" is vital for Mains.
