Collins examines the historical development of Motorola's Iridium global telecommunications project, which sought to provide cellular voice service to any point on Earth using a network of 77 low-orbiting satellites... Iridium's Apollo-like saga will capture the interest of general readers in engineering, science, history, sociology, and business, and will serve as an excellent capstone case study. Technical discussions are easy to understand, and the extensive endnotes and bibliography will satisfy the most rigorous scholar.—R. Dupont, Louisiana State University Alexandria, Choice
