Optical array telescopes in L2 are going to cost much less than estimated a few years ago, by making the big mirror/lens configuration obsolete
In the next 20 years, how many earth based telescopes will be built? How many space based?
If ted's comments about future observatories are correct, the answers would be:
1) no earth based observatories are planned or will be built as they are obsolete
2) all future observatories will be based in space
Clearly that is far from true. Almost all new observatories will continue to be built on earth, while only a few will be launched into space.
