Over the past six years, NASA's O±ce of Space Science has
implemented what may well be the largest single program in astronomy and space science education ever undertaken. The program goals include the public sharing of the excitement of space science discoveries, enhancement of the quality of science, mathematics and technology education - particularly at the precollege level - and supporting the creation of our 21st century scientific and technical workforce. This paper provides an overview of the program origins, policies and philosophies, and describes the development and growth of the program. Program accomplishments and the challenges that remain are discussed along with potential opportunities for international collaboration.
