    It is a gross exaggeration to say that a Hubble image with a satellite
    trail on it is "useless". Satellite orbits are well enough known that I
    am surprised they don't filter their observing schedule against sun
    illuminated satellites getting in the way. I guess for just 2% losses it
    isn't yet worthwhile but if it gets much worse it will be.

    The image may not be coffee table book pretty but it will still do the
    job for scientific purposes provided that the trail doesn't cross the
    usually quite small region containing the object being studied.

    Even if it did cross the target object and they were doing spectroscopy
    it would not often be enough to contaminate the spectrum of the remote
    object so the scientific value of the spectrum would not be harmed.

    I show it to my dog, but it doesn't care!
    I show it to my cat, it doesn't care, either!

    It remains to be seen if this becomes a problem of real significance.
    I suspect not. And it's likely that most future space telescopes will
    not be in low Earth orbit, so satellites won't be an issue.
