Here is NASA's video explaining the new budget (don't expect any statistics):
Space.com also breaks this down pretty well.
What I like:
- Increased funding for human spaceflight, so the US may close the gap between the Shuttle and the first launch of the SLS.
- Increased funding for Commercial Spaceflight.
- Increased funding for Earth Sciences.
- Overall decreased funding.
- Reduced funding for robotic missions.
- Lack of a clear commitment and concrete direction for the agency (beyond development of SLS).
The economics of space have been pretty well studied. The heyday of Apollo is the most often quoted figure, where $14.00 was returned for every $1.00 spent. I don't have figures for today, but I would imagine that the return on investment is somewhere around $7-$10.00 per $1.00 spent.
