Senate considers restructuring of NASA money

Space exploration is much broader than just NASA programs, and NASA is much more than just human spaceflight. Still, human spaceflight is the flagship mission, and the Obama administration's proposal to phase out NASA's ability to launch its own astronauts is sparking all kinds of conflict. One Senator suggest the money taken from the Constellation program and now pointed toward commercial human spaceflight be diverted instead to a new heavy-lift rocket that could boost Saturn-class payloads to the Moon and Mars.
