A cool project, but if you think of the thousands of folks who didn't get funding so this thing could gobble everything up - these projects really become crazy budget wise (SLS did the same path).

I wish they would do pay for performance deals. We'll give you $4B if you put a telescope in space of X size that meets some basic specs.

If you look at commercial side, space imaging (earth facing) has just exploded and the cost side has gotten very very good. So it's clear you can get optics and sensing into space for a lot less.
