They put the most advanced telescope at L2 which is the most remote location 1.5 million km away which can't be serviced and can't be rebuild easily.

It has nanometer optical precision in space which needs to be cooled through multiply layers of high tec foil.

Its mirrors are precicse to nm level.

Took 25 years of planning and 5 years of building.
