This book will provide for the first time a comprehensive manual on how NASA works and operates its programmes, opening the door to the general reader, and the visitor to NASA facilities, a directory of information on what to find, what to see and how it all fits together. This book avoids the detail on specific programmes and projects – these are already adequately covered in dedicated Haynes Workshop Manuals. Instead, it focuses on what exists at the various facilities across the United States and the technical parameters of their equipment and laboratory assets.
