Hubble's orbit has decayed over time. If proposals to reboost it come to pass (by SpaceX, no less), the problem will be ameliorated. If not, the telescope's near end of life anyway.

Meanwhile, future spaceborne telescopes are destined increasingly for far orbits (eg L2) to avoid the biggest photobomber of all - the Earth itself. In LEO it obscures nearly half the sky, limiting greatly what can be observed when - especially for long duration exposures. Far orbits bypass both that and satellite constellations.
