I like ISS
I wish they would finish it, so its work can begin.
Admitedly, it's expensive. I have no faith that NASA could make it less expensive. Until someone fixes NASA, or fixes the way one-of-a-kind, high-tech, and/or ground-breaking projects are done in the USA any more, then it could not be done any cheaper.
Anyone who thinks NASA can put a man on the moon or Mars for less than a whole lot more cash, is fooling themselves.
There will never be another Hoover Dam in this country. Take a look at the "big dig". We've lost the ability to do these things cheaply.
