B Where is the Hubble Telescope?

    I've read that Hubble is in geosynchronous orbit, but precisely what point on Earth does it remain in orbit over?

    It isn't. It's in a Low Earth Orbit.

    I see. So it does not remain over the same point on Earth. Thanks.

    No it doesn't, in fact it moves quite fast relative to the surface of the Earth.
    From most parts of Earth it is easy to see passing overhead a few times a year at night.
    Takes maybe 15 minutes to cross the sky at most.
    NASA have a timetable which people can look at to find out what times are the best for sighting at your location..

    If you put the NASA app on your phone you can set it up to alert you when certain things are passing over your location. I have used it to spot the ISS once or twice. The windows of time are just a few minutes, and it goes by fairly quickly. I'm not sure how view able hubble is.

    Oooops! = major inattention on my part, I thought this was about ISS :H,
    I'll put that down to overdoing it with multitasking, to many tabs open at once.
    Anyway as said above, NASA do have a number of apps and websites where all the info of missions is available for the public.
    (I think the Curiosity rover on Mars even has a presence on twitter!),

    If the NASA app was working on my phone, I'd be able to check, but it seems it stopped working after that last android update.

    The Hubble telescope has a lower inclination than the ISS, you need to be south of ~45°N and north of ~45°S to see it. It is one of the brightest objects in the sky for a few minutes if it flies overhead shortly before sunrise / after sunset (it has to be in the sun while the ground has to be in the darkness).

    45°N is a line going through northern Italy (Milano), Crimea, central Maine, Ottawa, North/South Dakota border, Washington/Oregon border and so on.
