H.R. 4412 would authorize the appropriation of about $17.6 billion for 2014 for activities of the National Aeronautics and Space Administration (NASA). The amount appropriated to NASA for 2014 is also about $17.6 billion. For the purpose of this estimate, the Congressional Budget Office (CBO) assumes that no further appropriations will be provided to NASA for fiscal year 2014 and we therefore estimate that no additional discretionary costs would result from enacting H.R. 4412.[1]
