1. George W. Bush proposed the Vision for Space Exploration program, which became Constellation, in 2004 as part of his re-election campaign, but he did nothing to build support for the program.
2. Under Bush, no new money was provided to NASA to begin the Constellation program; money had to be taken from NASA science, robotic missions, and human spaceflight programs.
3. To find seed money for Constellation, Bush canceled the space shuttle program and planned to abandon the International Space Station less than five years after completion.
