In January 2004 President George W. Bush put NASA in high gear, heading back to the moon with a space vision that was to have set in motion future exploration of Mars and other destinations. The Bush space policy focused on U.S. astronauts first returning to the moon as early as 2015 and no later than 2020. Portraying the moon as home to abundant resources, President Bush did underscore the availability of raw materials that might be harvested and processed into rocket fuel or breathable air. “We can use our time on the moon to develop and test new approaches and technologies and systems that will allow us to function in other, more challenging, environments. The moon is a logical step toward further progress and achievement,” he remarked in rolling out his space policy. To fulfill the Bush space agenda required expensive new rockets—the Ares I launcher and the large, unfunded Ares V booster—plus a new lunar module, all elements of the so-called Constellation Program. The Bush plan forced retirement of the space shuttle in 2010 to pay for the return to the moon, but there were other ramifications as well. Putting the shuttle out to pasture created a large human spaceflight gap in reaching the International Space Station. The price tag for building the station is roughly $100 billion, and without the space shuttle, there’s no way to reach it without Russian assistance. In the end, the stars of the Constellation Program were out of financial alignment. It was an impossible policy to implement given limited NASA money.
