The U.S. National Space Policy (NSP) was authorised by President Bush on August 31, 2006. This NSP establishes an overarching national policy that governs the conduct of U.S. space activities and supersedes the 1996 NSP. The unclassified ten-page summary of the NSP consists of 13 self-contained sections including the principles, goals, guidelines (both general and specific to national security space, civil space and commercial space), international space cooperation, space nuclear power, radio frequency spectrum, orbital debris, effective export policies and space-related security classification. The first part of this review focuses on the principles and goals of U.S. 2006 space policy as these provide the overall rationale to the policy. The second part of this review of the 2006 NSP highlights the context of the policy, a comparison with the previous policy, commentaries of the policy by others and some final observations.
