The U.S.President Bush’s budget plan for 2005 includes the funds for open space explorations within the sending explorers to the moon and Mars. NASA also has an option to end the work of aging Hubble space telescope.

The spending plan for NASA 2005 space exploration is 2.4% higher than estimate and accounts for $16.5 billion, including $4.5 billion for the space shuttle program and $1.85 billion for the international space station.
NASA spending plan is a little lower than Bush promised after the Columbia shuttle accident. "The vision for space exploration remains an administration priority even in this challenging budget environment," said NASA Administrator Sean O’Keefe.

NASA is not planning to save the Hubble with its robotic mission. Still, NASA will keep developing of the Project Constellation, which is set to be launched by 2008 with the possible moon-flights by 2020.

The National Aeronautics and Space Administration is also having an option to complete the work of aging international space station by the end of 2010.
