NASA stands for the National Aeronautics and Space Administration, the United States government agency responsible for exploring space and advancing flight technology. Founded in 1958, NASA designs and launches spacecraft, studies planets and stars, and works to answer fundamental questions about the universe.

NASA's achievements read like an adventure story: landing astronauts on the Moon during the Apollo missions, sending robotic rovers to explore Mars, launching the Hubble Space Telescope to capture stunning images of distant galaxies, and helping build the International Space Station, where astronauts live and work in orbit around Earth. NASA scientists and engineers also study our own planet, tracking weather patterns, monitoring climate, and watching for asteroids.

When people dream of becoming astronauts or designing spacecraft, they often imagine working for NASA. The agency employs thousands of scientists, engineers, mathematicians, and other professionals who tackle some of humanity's most ambitious challenges. From studying black holes to testing new aircraft designs to planning future missions to Mars, NASA pushes the boundaries of what's possible.

The agency's name reflects its dual mission: aeronautics (the science of flight within Earth's atmosphere) and space (everything beyond). While NASA is famous for dramatic rocket launches and space exploration, it also quietly improves the aircraft we fly in every day.
