Well, NASA is probably the most famous space agency in the world. In 1958, President Eisenhower presided over the creation of the National Advisory Committee for Aeronautics, which was later incorporated into the National Aeronautics and Space Administration. It has known several ups and downs, successes (Moon landing, SkyLab, Space Station), and disasters (Challenger, Columbia). One of current NASA’s goals is to return to the moon and build a sustainable, long term human presence there. As the International Space Station (ISS) is completed, and the space shuttle program moves toward retirement, NASA is busy developing the next fleet of vehicles, designed for moon and possibly Mars missions.
