The U.S. Congress passed legislation establishing the National Aeronautics and Space Administration (NASA), a civilian agency
responsible for coordinating America’s activities in space, on July 29,
1958. NASA has since sponsored space expeditions, both human and
mechanical, that have yielded vital information about the solar system
and universe. It has also launched numerous earth-orbiting satellites
that have been instrumental in everything from weather forecasting to
navigation to global communications.
