People usually measure this as percentage of GDP, not absolute dollars.

  No they don’t. Why would a budget scale with GDP?

    A couple of reasons. One is that NASA is an arm of the United State's advanced research, and if you want to get compounding returns there the goal is that you allocate a proportion of your spending there rather than a fixed value, because every year some of that research will drive gains to your GDP. Another is that the services that NASA provides gradually expands as it provides more things to society: I expect that alongside space exploration there is an increasing budget allocated to dealing with civilian spaceflight. So if you keep the budget constant then you are necessarily prioritizing some things over others, which means a net decrease to specific programs. Of course, none of this means it should be pegged at a specific fraction of the GDP, it's just a helpful metric to compare against when we look at overall spending. I expect its budget to fluctuate naturally as our needs from it change, and there are certainly programs that have fixed budgets (or even need less money as time goes on) that we should still be looking at. But in general the spending for things like NASA should gradually increase because of its goals.

      I agree with that. But that’s different than saying “NASA's budget has been cut so back over the years.” The military budget has been shrinking as a share of GDP since the 1980s as well. It would be odd to say the military budget had been cut back though.

        Arguably it makes more sense for military budget to reference GDP since military capability is relative to that of one’s adversaries. If their capability has increased, then so must ours to achieve a net zero difference. And their capability is proportional to their spending ability with everything else kept equal.

        You're too smart to make that comparison. 1980s we were in the middle of a VERY strong cold was with the USSR. Every American agrees that military focused has decreased since then, while scientific focus/interest/value has increased.

  Why would I measure it that way? What matters is the capacity of NASA's ability to do things, based on its funding. You can argue that an outfit like NASA should get more or less funding, but it should be based on what you want them to be able to do, not some arbitrary measure like a percentage of GDP.
