The House Appropriations Committee's NASA spending bill, expected on the House floor this week, cuts the agency's topline $83.2 million below the Bush administration's request but adds money for aeronautics and science. The committee recommends $16.7 billion for the agency in Fiscal 2007, with only what it terms "modest changes. . .to achieve a balance between exploration and NASA's other core mission programs." The committee beefs up aeronautics by $100 million, for a total of $824 million. The science budget is about $5.4 billion, an increase of $75 million to boost research and analysis ($50 million), continue work on the Terrestrial Planet Finder mission ($10 million) and begin planning a mission to Jupiter's moon Europa ($15 million).
