Huge Puerto Rico radio telescope collapses; many mourning
by Dnica Coto
A huge radio telescope in Puerto Rico that has long played a key role in astronomical discoveries collapsed on Tuesday, officials said.
The Arecibo Observatory had been shuttered since August after an auxiliary cable snapped and caused a 100-foot gash on the reflector dish. Then a main cable broke in early November, leading the National Science Foundation to declare just weeks later that it planned to close the radio telescope because the damage was too great.
Many scientists and Puerto Ricans mourned the news, with some tearing up during interviews.
It is the second largest radio telescope in the world and had been operating for more than half a century.

I checked AP. I can't find it there. I'll put that up when I get it. I can find a lot of articles saying that collapse is immiment.
The demise happened quickly. Officials just put the antenna off-limits a few months ago. There were threads at DU about that.

(6,700 posts)Or their "perfect", over-fertilized, lawns which I hate. Stay away from the garden centers. It's a slippery slope.
Many may have assumed it was only a prop for Goldeneye anyway. Filmed in Pierce Brosnan's back yard.

The Arecibo Observatory employed hundreds of local workers.

(12,482 posts)Almost every weekday school buses filled with kids from all over the island would visit, and get to use the real-time planetarium displays in the adjacent museum building.
Earlier this year SETI@Home discontinued signal analyses, much of the data came from the huge Arecibo dish reflections. Sad ending because the scientific community did not come to the rescue.

Turns out it was just cosmic noise.
I have to say that Contact is my favorite movie of all time.

(6,092 posts)RIGHT! The failure president. Failure to help PR with repairs after the hurricane certainly attributed to the ultimate collapse. tRump breaks everything he touches.
electric_blue68
(14,598 posts)for a nano sec I was confused about which president but then your words, the video I saw on line of his tossing the effing paper towels, the photos of the people, the devastation in San Juan, and then hearing their stories from the cities to way out into the countryside all came rushing back.
I remember asking aquaintences about their families in PR.
Damn that selfish, ignorant, rascist bastard!

#BREAKING: The #AreciboObservatory has entirely collapsed!
😥
Here's my article published just before the news broke -- "Lament for Arecibo" -- in @BulletinAtomic
Hurricanes, earthquakes, and now this. A Puerto Rican scientist's lament for the loss of a legend...
The National Science Foundation has announced it will demolish an icon of science, and of Puerto Rico.

Via my colleague @DeborahTiempo here is the picture of the remaining support towers at #Arecibo this morning. It shows that the 900-ton suspended platform that held the receivers and transmitters has collapsed. Dust from the incident still floats in the air at the time of the pic

Damn

(127,261 posts)and it was obliterated (took a 9 months to replace) -
Arecibo is about 40 miles due west from San Juan.
Path of Hurricane Maria (the eye didn't even go over San Juan) -
There was no way, even if it were maintained. It didn't have a chance.

(9,895 posts)NASA has no currently viable or operating launch vehicles.
SETI is all but defunct and has no radio telescope to utilize at Arecibo.
FDA/CDC have been co-opted to political propaganda in service to an imbecile.
WHO membership was pulled and the USA dropped out.
Paris Accords were pulled out (though Biden has pledged to reverse these in his first 100 days...)
Science and rational thought are antithetical to "conservative thinking", at least as it has been narrowly redefined since Reagan - a constant dumbing down and least-common-denominator approach ever since the insane idea of "Star Wars Missile Defense" was first brought up back in the waning days of the Cold War. At least there was some strategic value to SDI in that it contributed to the USSR bankrupting itself to compete militarily against a vastly larger economy (something that our current leaders had better start understanding as the Chinese will very soon be in position to do the same to the USA).
A society that embraces basic research as a national emergency is one that can do anything - hell the entire space race and all that came from it was essentially Cold War propaganda in its reasoning, but the ancillary benefits and all the technology that it spawned also led to the current technological boom in no small measure too.
I cried the day that NASA shut down the shuttle not because the shuttle was a great financial boondoggle but because shutting it down without a replacement at the ready signaled an end to America's ambition and commitment to something beyond ourselves and beyond profits or money.
Today those same feelings are renewed.

(1,295 posts)Arecibo was not just a telescope, but a radar dish. With radar we could accurately measure the distances to solar system objects, and get substantial information about their surfaces. Without those measurements, we cannot plot asteroidal orbits accurately enough to ascertain when there's a threat of collision.
We need to build a new radar facility. But this time, instead of a single giant dish we can make a hundred normal-sized ones working in tandem.
electric_blue68
(14,598 posts)Though for asteroid tracking - the more "eyes" the better, I'd hazard an educated guess!
paulkienitz
(1,295 posts)The next best asteroidal radar has only like one fifteenth of the ability to pick up faint echoes. We either need another great big dish, or an array of dozens of medium sized ones that add up to as big an area. The latter is probably better because it would be able to steer over a wider part of the sky.
electric_blue68
(14,598 posts)An array sounds better.
I wonder if with an array site they could even move some of the dishes at the edge of the array to figure out the shape better. 🤔
Love astronomy!

Scott Manley has a good video, with some newer photos of the destruction.

(127,261 posts)I know I ran SETI@Home with a team for 20 years and most of the data came from that radio telescope. It will be sorely missed although it has pretty much been out of service for some time now.
And as another movie nod, it did appear in the movie "Contact" too.
