"Democrats in the House are set to unveil their own NASA authorization bill, which unlike a much leaner Republican proposal due to be marked up June 10 would authorize $18 billion in spending for 2014 -- more than NASA has gotten since 2011.
... The Republican bill would ban an asteroid retrieval mission the Obama administration proposed in April and instead direct NASA to send more astronauts and hardware to lunar space. The Republican bill, which assumes NASA will be subject to across-the-board sequestration cuts for the foreseeable future, also called for shrinking NASA's Earth science program and restructuring NASA management.
The official summary of the Democratic bill mentions none of these things, and directs NASA to only one destination: Mars. The agency would be on the hook to draw up a 15-year Mars road map for Congress, under the Democrats' bill, but it would be entirely up to NASA to decide whether the road to the red planet included detours to the Moon, asteroids or Mars' natural satellites. "
