4. Finally spoke with My Son The Astronomer about this.

The Arecibo telescope has two ways of observing, as a radio telescope and as a radar telescope. There are any number of other radio telescopes out there, more than a hundred. You can check it out here: https://en.wikipedia.org/wiki/List_of_radio_telescopes

The radar telescope function is something else. There is only one other radar telescope in this country, Goldstone in California. Radar telescopes are good for certain, very specific things, and mainly with objects that are relatively close, inside the solar system. Apparently is radar that has allowed us to have some idea of what the surface of Venus might be like. Radar is also a good way to track things like comets and asteroids that might possibly pose a danger. So it's too bad we're losing Arecibo because from what I see in the wiki article about radar telescopes, https://en.wikipedia.org/wiki/Radar_astronomy it's far better than Goldstone.

But my son says there just doesn't seem to be the funding and the will to rebuild or fix Arecibo.
