While the space shuttle was being recertified for flight, NASA moved forward with a new “Vision for Space Exploration,” announced by President George W. Bush on January 14, 2004. The Vision called for completing the ISS and retiring the space shuttle by 2010. Meanwhile, NASA would develop the new Constellation Program, which included expendable launch vehicles and the Crew Exploration Vehicle (Orion), which was a capsule like Apollo, but on a larger scale.
