NASA-the National Aeronautics and Space Administration created in the wake of the Space Act-has and continues to accomplish those precepts every day. With many hundreds of satellites launched into space and close to 200 human spaceflights, NASA is a proven leader in space exploration. Most of the US space exploration efforts have been led by NASA, including the Apollo moon-landing missions, the Skylab space station, and later the Space Shuttle. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the Space Launch System and Commercial Crew vehicles. NASA is also responsible for the Launch Services Program which provides oversight of launch operations and countdown management for unmanned NASA launches. The Historical Guide to NASA and the Space Program contains a chronology, an introduction, appendixes, and an extensive bibliography. The dictionary section has over 500 cross-referenced entries on space missions, astronauts, technical terms, space shuttles, satellites and the international space station. This book is an excellent access point for students, researchers, and anyone wanting to know more about NASA and space exploration.
