Professor Reynolds has some thoughts, with which I obviously agree:

Space enthusiasts, God knows, have seen plenty of disappointment in the past few decades, as the brief false dawn of Apollo led to years of failed promises and no visible momentum. But we're now seeing signs of new technologies -- and, just as important, new systems of organization -- that make a takeoff into sustained growth much more likely for the space sector. Prizes to develop technology, space tourism to develop markets and help us move up the learning curve, and people with the money and vision to provide the seed capital for both: The essentials now look to be in place. It's about time.

And other than the potential prizes, much of what NASA is doing seems increasingly irrelevant.
