    Hubble is essentially a Keyhole satellite so I assume if they flipped it around we’d have really clear photos of earth similar to the one trump got in trouble for showing on live tv.

      Not really. Hubble is set up to image objects light years away and moving relatively slowly.

      Keyhole stats as set up to image the earth’s surface that is only hundreds/thousands km away and moving quite fast.

      Two different missions would lead to two different designs.

        That would lead to different focal lengths not different designs completely. Both optical systems for HST and KH were designed by Perkin Elmer so I’ll stick with my first thought that they would be very similar in capabilities.

          Did you watch the video?

          The tracking problems Hubble would have imaging the earth surface are a direct guide to what differences the design would be.

            Did you finish the video where they essentially say what I said in my first comment? Hubble and spy satellites share a lot of the same technologies. I wasn’t aware of the speed issue but other than that they are similar like I said.
