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.
