    Actually I read a proposal based on an array of satellites. Not sure what orbital path they would be on but Spacex has shown how viable and cost effective it could be. It would be a leap forward for science so the costs could be shared with other countries. Not like it hasn't been done before. The costs to build Arecibo was astronomical back in the day so I don't see the issue if it advances science in a similar manner.

    I was working in Arecibo in April on an unrelated HF project when the cable broke. I was pretty bummed out as I had planned on visiting the telescope. A lot of history there and no telling how many movies were made. I can see where is would be beyond economical repair however. I believe the VLA has better resolution and can look out farther than the Arecibo scope did and is adjustable. Still, it's sad to see it go.

    The Jansky telescope is predominantly an imaging array and does not have the collecting area of the ( SK)Arecibo dish. Arecibo's unique sensitivity was instrumental in many key discoveries, including the first extrasolar planet, and the binary pulsar used to show gravitational wave dissipation.

    Really sad to see the demise of the Arecibo Telescope. Featured also in a nice ham-radio video on moon bouncing activities by swiss radio amateurs back in 1964 (for a trip down memory lane see youtube-video "How high the moon": , including English sub-titles).

    Only?

    I was a tracking system engineer for the U.S. Navy. I won't go into details. But this radio telescope what a huge pain in bottom for anybody having to do with radiating any radio signal anywhere in the region. That part of the world is much more developed now than it was when it was first put there. If there is truly a need, it needs to be more properly located... if not out in space.

    My thoughts exactly, when I saw the drone catch the moment of failure. Perhaps it had a built in 'failure prediction circuit' like HAL 9000. ;)

    I suppose that's what we get for not repairing the AE-23 unit as instructed.

    The drone footage is there because over the weekend prior to the failure, multiple outer strands were failing on Tower 4's cables. That intensified the drone focus on Tower 4. One should not be surprised at all that observations were there at the critical moment. AO staff were diligent in spending hours with DJI drones at exactly the spot where they thought the most stress occurred.

    Notice all the paint missing from the cables - that's the outer strands breaking and taking the white paint with them.

    Scott Manley's analysis of the failure is excellent, if you can stand to watch the footage again (I can't):

    Wait for NASA, Musk and Bezos getting back on the Moon. Select a nice big crater on the dark side and have at it :cool:

    Precisely. From what I hear - (Sneering wistfully in deep throat manner):
    — If they do go, they won't ever be coming back, from there ....
