Less than one year after the Columbia Space Shuttle accident on 1 February 2003, President George W. Bush announced at NASA Headquarters that the Agency would embark on a new Vision for Space Exploration as it resumed Shuttle flights and worked toward completion of the International Space Station. The President’s ambitious agenda included lunar and Martian exploration with robotic precursors followed by human missions. The conceptual foundations of the President’s plan had their origins in 1999, when NASA Administrator Dan Goldin initiated a Decadal Planning Team to generate viable plans for humans and robots to explore space beyond low-Earth orbit. This book provides a detailed historical account of the ideas, debates, and decisions that opened the way for a new generation of spaceflight at the start of the 21st Century.
