wulfrun Posted December 1, 2020 Share Posted December 1, 2020 (edited) 900 tons falling 450 feet - I bet there was some bang from that. Tragic loss, a very sad day but as said above, not unexpected. Doesn't look like it will or could be rebuilt either. Good job there was some suspicion and it wasn't unexpected, so at least no-one's hurt.

John Posted December 2, 2020 Share Posted December 2, 2020 Imagine the "For Sale" advert - some signs of wear from normal use but some TLC will soon sort these out. - buyer must make own carriage arrangements. - buyer to provide suitable topography for mounting the instrument. - strictly no returns ...... 1 2 Link to comment Share on other sites More sharing options...

Perhaps a DIY ‘fixer upper’ project for some billionaire amateur astronomer? 1 Link to comment Share on other sites More sharing options...
Peter Drew Posted December 2, 2020 Share Posted December 2, 2020 Sad as it is for science, spare a thought for the local community for which the telescope was a huge economic benefit through tourism and services. Many livelihoods will have been affected as well as those of the scientific elite. ☹️ 5 Link to comment Share on other sites More sharing options...

Seriously though, a huge loss for astronomy and Puerto Rico. Arecibo was on my fantasy list of observatories to visit. The one silver lining is that they had not decided to repair it and had people working on it at the time of collapse.

Nik271 Posted December 2, 2020 Share Posted December 2, 2020 Sad news At least it proves that the previous assessment that it was too dangerous to fix was correct. Link to comment Share on other sites More sharing options...

It was the top of it collapsed into the dish. I think it was one of the cables supporting the dish off the ground that snapped first. The whole thing, including dish, was suspended off the ground.

"See these arms that were broken How they held you so" OK, cables rather than arms, but you don't get many songs about telescopes to choose from. This will probably be opaque to anyone under 45.

I can’t resist adding the next verse. We're just waiting, looking skyward As the days come down Someone promised there'd be answers If we stayed around. 1 Link to comment Share on other sites More sharing options...

It looks like failure of the cables/anchors was expected. Some tension in those cables, it all just disintegrated once the loads became imbalanced. I'm not sure I'd have walked out to that focal cage at any time in its history. Link to comment Share on other sites More sharing options...

wulfrun Posted December 3, 2020 Share Posted December 3, 2020 Very painful to watch, especially as it's also fascinating - you almost feel guilty watching a mighty structure collapse. Looks from the drone footage that one or two wires ping and that triggers the total failure, it must have been teetering on the brink prior. Just glad it was a drone, the whip from those wire ropes could have gone in any direction. Link to comment Share on other sites More sharing options...
markse68 Posted December 4, 2020 Share Posted December 4, 2020 Why did they have a drone out filming it- pure chance or was it a planned demolition? Mark Link to comment Share on other sites More sharing options...

Mark It may have been in use for inspection and just coincidence it was there - it'd be an ideal, safe way to see what the state is. The footage looks very steady and zooms out a long way, it may even be mis-labelled and a remote CCTV of some sort and not actually a drone, who knows. Whichever, it's interesting how it shows the sequence of the failures pretty clearly. Link to comment Share on other sites More sharing options...

Louis D Posted December 4, 2020 Share Posted December 4, 2020 On the bright side, the Chinese stepped up a few years back and built an even bigger radio telescope of similar design. Still, sad to see a famous old radio telescope go in such a horrible fashion. Link to comment Share on other sites More sharing options...
Seelive Posted December 4, 2020 Share Posted December 4, 2020 As far as I'm aware, unfortunately the Chinese telescope doesn't have the RADAR capability that Arecibo had. Link to comment Share on other sites More sharing options...
