Even with a $500-million-dollar boost compared to last year's total, NASA is only being provided with a potential 0.46% of the Federal Budget. While you'll hear many hearty claps and hoorays at the targets for this budget, this would be another in a long line of drops in percentage-of-total for the federal budget for NASA. The last time NASA received any amount over 1% of the total federal budget was back in 1993. Not that NASA could use the money for anything important like saving humans from an extinction level event, or anything like that.
The good news is that the actual cash NASA will receive is above last year, and the year before that. Obama's administration hasn't been extremely shy about sending money to scientific research, especially in the stars, over the past several years.
