Supporters believe that this plan will be an important part of what Bush set in place while in office. However, the policy has been criticized on two fronts. Firstly, critics have opined that the United States should deal with solving domestic issues before concentrating on space exploration. Secondly, of the funding over the next five years that Bush has proposed, only US$1 billion will be in new appropriations while the remaining US$11 billion will be reallocated from NASA's other programs, and therefore inadequate to fully realize this vision. Most of the spending for the new program, and most of the budget cuts for existing programs, are scheduled after the last year of the Bush presidency. It is unclear how the space vision will be reconciled with budgetary concerns in the longer term.
