Gary Dorsey"s Silicon Sky tells the engrossing tale of a private company"s quest to develop the world"s first low-earth-orbit commercial satellite--a momentous accomplishment that paved the way for everything from reasonably priced GPS navigational receivers to pay-at-the-pump credit-card terminals at filling stations. Dorsey tackles the true story of the emerging world of "microspace" in a manner reminiscent of Tracy Kidder"s pioneering The Soul of a New Machine, using an interesting combination of first-hand observations, critical analysis, and literary techniques usually found in novels. By sticking close to Orbital Sciences Corporation"s extensive cast of characters working in the early design stages in 1992 through the product launch in 1995, Dorsey brings readers into the labs and boardrooms as the fledgling operation grows into a booming company that entered 1998 with $3.9 billion in orders already in its books. --Howard Rothman
