RH | 5,206 Posted November 20, 2020 Share Posted November 20, 2020 It's a sad story, but it looks like "the cradle" is closing for good. This doesn't appear to be so much a budget issue or a lack of support for science. Apparently, a couple of support cables have snapped and engineers cannot think of a safe way to repair it. In fact, they aren't even sure how to safely dismantle it and, as such, the whole observatory is simply closing. https://www.scientificamerican.com/article/legendary-arecibo-telescope-will-close-forever-and-scientists-are-reeling/ 1 Link to comment Share on other sites More sharing options...

Seems hard to believe that they would have build something of that size and scope without clearly documented plans, in advance, of how to repair it or dismantle it.

Though that does make sense, scientists and engineers can't account for everything. There had also been an earthquake that had done damage and, frankly, it might have been a problem compound from that. Keep in mind, this facility is rather old. Our engineering is much more sophisticated than it was in the mid-70s when it was built. I think this observatory has had pretty good funding over the years. I don't really think it fell into disrepair due to negligence, other than someone not going over the maintenance plan every 10 years with a fine tooth comb and re-evaluating the whole thing.

glazball | 176 Posted November 20, 2020 Share Posted November 20, 2020 (edited) My understanding, from the articles I read yesterday, is that it's simply too dangerous to send people in to dismantle it. So, it will be left to collapse on its own - which it is expected to do since the second cable broke. Hopefully in a few years we can replace it or build another instrument in its place. The Arecibo area is considered a scientific hub and the people there don't want to lose that. It's upsetting but we can rebuild!

Yeah, I didn't consider this a "good thing" but the silver lining is that when stuff like this has to be abandoned, but it's important, it likely means that something better might come along. Let's hope that after 50 years, it's replacement can be many magnitudes better and maybe even cheaper to build and operate. 1 Link to comment Share on other sites More sharing options...

Looked it up out of curiosity -- it was built from 1960-1963 -- meaning it was designed in the 50's. So I suppose that leaves me less surprised that they didn't think far enough ahead about how to replace major elements safely.

TrekMD | 1,498 Posted November 20, 2020 Share Posted November 20, 2020 (edited) This is my hometown. Very sad to see this is going to happen. I am thankful that I got to visit it more than once and even got to fly over it and visit the towers that hold the core part in place. It really is an impressive thing to see. I do understand why they have to do it, though. Edited November 20, 2020 by TrekMD 1 Link to comment Share on other sites More sharing options...
RH | 5,206 Posted December 1, 2020 Author Share Posted December 1, 2020 Well it happened. The main receiver in the middle broke and fell. https://weather.com/news/news/2020-12-01-arecibo-observatory-radio-telescope-collapses?cm_ven=hp-slot-1 Sorry, there's probably a better source, but this is where I found the news. 1 Link to comment Share on other sites More sharing options...
ThePhleo | 2,266 Posted December 1, 2020 Share Posted December 1, 2020 Sometimes we need to take a step back to make two steps forward. This has the scientific community in a state of shock, and I'm sure it will drive them to seek funding for a replacement. Maybe in a different place, maybe in a different country all together, but I'm sure if good science can be acquired from a project such as this then a replacement will be made eventually. 1 Link to comment Share on other sites More sharing options...

As a matter of self-interest, most of us here should probably want it to stay in the USA or a US territory. 1 Link to comment Share on other sites More sharing options...
Ferris Bueller | 508 Posted December 2, 2020 Share Posted December 2, 2020 I visited the observatory once and remember watching it move while the guide talked about how many tons it weighed. 1 Link to comment Share on other sites More sharing options...
TrekMD | 1,498 Posted December 2, 2020 Share Posted December 2, 2020 I learned about this earlier today. How sad. I wonder if something else can be built there to at least continue the science. 1 Link to comment Share on other sites More sharing options...
