In this fascinating foray into the millennia-long relationship between science and military power, “the world’s best science communicator” (Times Literary Supplement), astrophysicist Neil deGrasse Tyson and writer Avis Lang examine how the methods and tools of astrophysics have been enlisted in the service of war. “The overlap is strong, and it’s a two- way street”, say the authors, because the astrophysicists and military planners care about many of the same things: multi- spectral detection, ranging, tracking, imaging, high ground, nuclear fusion and access to space. Tyson and Lang call it a "curiously complicit” alliance.

Spanning early celestial navigation to satellite-enabled warfare, Accessory to War is a richly researched and provocative examination of the intersection of science, technology, industry and power that will introduce Tyson’s millions of fans to yet another dimension of how the universe has shaped our lives and our world.
