Hubble's mirror design changed to match the existing mirrors already deployed in spy satellites -- Aiming an army of Hubbles at earth? That's some awesome spying capability; No terrorists or enemies could make a significant move against us without us finding out immediately already thanks to space spying programs. And, when we launch more impressive satellites the old spy-sats can be donated to NASA and pointed into space, or sent to other planets. [space.com]
I think you have that backwards. The NSA gets the most advanced toys first, why do you thing they changed Hubble's design? Because the spy telescopes were more powerful.
That isn't what I logged in to say, though -- even though TFA was published yesterday, they must need some lead time because the Senate just voted for a budget, no more sequesters for two more years. My guess is the article was written and edited weeks ago.
