I meant 500 experiments on the ISS - but even looking at your list, isn't that a perfect example of incremental science? Mapping, more mapping, more detail. Better resolution of the Hubble constant. Some more probes (technology that dates back to Voyager). The Mars rovers don't have any technology that wasn't around in the 80's. Nothing wrong with any of this, but it's the clean up work that happens in dull periods. Contrast that with the 50 year period going from the development of the modern rocket to landing on the moon. With the first artificial satellites going up along there.
If someone in the early 70's had seen your list, they would have laughed and said "that's it"? By now we were supposed to have permanent settlements on the Mars and moon, space elevators, Bussard ramjets, exotic matter factories, mineral harvesting in space. We were supposed to be comfortable operating in the asteroid belt. On the other hand, everyone knew we were going to find extra-stellar planets. The math dictated it. Actually finding them was tidying up loose ends. And dark matter is the new ether - it's so obvious until one day it's not. This isn't any sort of "golden" age. We still don't even have a viable candidate for a unified theory, and everything since Einstein and Dirac have been increasingly wild attempts to get equations to balance.
So what's NASA going to do with more money? Throw bigger and bigger mirrors into orbit? Create another boondoggle like the shuttle, which was supposed to be a "cheap" launch vehicle? That's all old science. Show me something new.
Look at your list of projects. If those were Kickstarter projects, how many lay people would throw their own money in?
