In this book, Patrick Norris responds to the 50th Anniversary of the dawn of the Space Age – the launch of Sputnik 1 – with a review of the most important historical applications of space science for the benefit of the human race during that half century, focusing on the prevention of nuclear war.

"[Seize the high ground is a] narrative history of the Army's aerospace experience from the 1950s to the present. The focus is on ballistic missile defense, from the early NIKE-HERCULES missile program through the SAFEGUARD acquisition site allowed by the 1972 ABM Treaty to the more advanced 'Star Wars' concepts studies toward the end of the century. [What is] covered is not only the technological response to the threat but the organizational and tactical development of the commands and units responsible for the defense mission"--CMH website.
