The US should be funding NASA with a budget that is 1% of the federal budget. From: The GPO, NASA's projected budget is just about 16.3 billion for FY07 if I read the chart correctly. If I read the overall chart correctly, the federal budget it just over 2.7 trillion. If NASA has 1%, the extra 4 billion dollars or so would speed up VSE and probably close the gap between 2010 and 2012-14 when Ares I launches with its first crew. NASA needs to increase manned launch rates. Current projections see Ares launching only 4 times a year per vehicle. And that's without ISS flights.
Not that I'm hoping Elon or Kistler will fail, but NASA needs to have the excess production capacity to resupply the ISS AND go to the moon.
