I’m really looking forward to when the new large array ground based optical telescope network comes online. The adaptive optics will take our atmosphere out of the equation and I’ve read that it will make Hubbel obsolete.

Also being ground based makes it cheaper to maintain and repair.

But then imagine what we could discover if we had a similar array on the moon ... or located at the Lagrange points in our Solar System!

Hubble will still be better for taking very long exposures. Consider that a ground-based telescope can only be used at night. Hubble can be used 24x7, and it’s steadier when pointed at a specific object. It’s not subject to vibrations or irregularities from the motors that move a ground-based telescope to keep it pointed correctly.
