A few comments saying it is cheaper than X which is much worse than a space telescope but to me, that is irrelevant. They are proposing to spend this in addition to all the other garbage they spend money on so the comparison is not logical. By the same logic, I can say that we shouldn't spend $10B on a telescope when we could invest it in one of many humanitarian exploits like micro-finance for developing countries, systems for clean water and sanitation etc. If the question was, "should we spend $10B of the military budget on this instead of tanks?", then fair enough.
