Kind of pricey, isn't it?
The U.S. share of an Earth-based system is over a quarter of a billion dollars?? Do we really need telescopes with solid diamond mirrors? What the heck do they need this kind of money for? Isn't NASA currently spending about $4 million on this, with fairly decent results?
I would like to see evidence that a damn good Earth-based NEO detection program could not be mounted for one hell of a lot less money.
