>Q: Is there any other way to get into space?
A: Not from U.S. soil once the shuttles retire. NASA could eventually use the commercial rockets and capsules being developed by private companies. Two companies predict they could fly astronauts to the space station within three years. NASA is under orders to build a giant rocket to go beyond Earth orbit.

What strikes me is the area under this curve: funding was very high in the space race, but total dollars spent from 1980-2010 are huge too even after inflation.
However, % of federal budget paints a grimmer picture on what the feds value. http://c85c7a.medialib.glogster.com/paulsoma/media/e8/e87670...
(Well, there is a third US human spacecraft in sight, but I suspect it will be irrelevant compared with the other two.)
