KH-11 spysat design revealed by NRO’s telescope gift to NASA (2012)
You can tell from my username that I have some opinions in this area.<p>My questions are these:<p>NASA can barely keep JWST on a delayed schedule without massive cost overruns.  What is another telescope good for?  How many astronomers and support staff do we need in this industry?  How do we measure and know that it&#x27;s enough?   What&#x27;s the breakthrough that another telescope at the cost of $Bs would achieve?  (and please be specific if anyone is going to reply, not just the old &quot;because it&#x27;s worth doing&quot; argument -- that could justify any amount of spending)<p>These are the things you think about after you leave a field and are not beholden to it any more.
