Worlds Largest Radar Astronomy Dish To Be Demolished!

[@marko4134]

Hi Scott, as someone who's done work at Arecibo and am now working at FAST I'd like to thank you for this video. For many of us who learned how to be radio astronomers at Arecibo, these last few months have been difficult. I'd also like to add that your comparison of Arecibo's range is incomplete. There is a further reason why Arecibo was so uniquely good at planetary radar. The larger the antenna, the small the beam size (or greater the magnification). So not only was Arecibo able to collect more signal as a receiver, it was also able to pack the transmitted power into an area on the sky that's about 10 times smaller (100 times less area) compared to the DSN antenna. The only other telescope which could conceivably do this is FAST. But FAST has a much smaller feed structure (the structure hanging over the dish) that weighs only about 30 tons. It simply could not support the weight and power requirements of a radar transmitter without major upgrades and redesign. Excellent video, Cheers

[@guyjones4936]

I pray they can safely take it down and then invest in a new telescope with all new tech for a new generation of scientists!

[@Kevin_Street]

That's really interesting! Thank you for adding to the discussion.

[@frzstat]

Great comment Marko K!

[@CKOD]

Just to give an idea of the focusing, Goldstones EIRP (how much power it would take to get the same strength, if you were transmitting in all directions instead of a tight beam, a way to compare two different antennas of different directionality like this) is 363 GW on X-band, and Arecibo was 20TW EIRP on S-band. Arecibo has a monstrous amount of directional power (as if the radar imaging of other planets didnt make this apparent)

[@andrewd7112]

@Marko K Hypothetically, could Goldstone transmit radar and FAST use its larger diameter to receive return from more distant objects? I asked myself what we would do now if needing confirmation a distant object was on collision course for Earth and that's the thought that popped up. Earth curvature and rotation would be complications but could it be done?

[@AlexWaardenburg]

I'm a draw bridge engineer and I speculate they haven't been doing inspections if they were caught off guard by this rope failure.

[@hugmynutus]

All but confirmed. The telescope was slated to close for a number of years. It has been bouncing between various foundations & universities due to the high maintenance costs. Everyone wants to use and own a famous scientific instrument, but nobody wants to pay to keep it working.

[@timberwolf1575]

@bulletsholes Compound that with administrators from a science background instead of engineering. They should have someone with a suspsension bridge background on staff. Bet they didn't. I would also bet that they played games with local building codes to classify the structure as something with low inspection requirements.

I was enthralled by these stories, even though we were working on one of the largest concrete projects in the country at the time. It’s sad the structure has failed. We will need to rebuild it.

Greetings Scott, I'm Puerto Rican and my family and I are members of the Astronomical Society of the Caribbean. As a amateur astronomy group we used to set up personal telescopes on the viewing platform of the visitor center and do stargazing nights. We used to get hundreds of visitors during those nights and I had the blessing to attend these at least 2 to 3 times per year. I'd say in the last decade I've visited the Observatory around 25 times, but since then I've moved out of Puerto Rico and the sad news hits hard. This might be sad news from a Science perspective, but from a local cultural perspective the news is devastating. The Arecibo Observatory was a focal point of pride for Puerto Ricans and a potent symbol of our island, not to mention the amount of international visitors it attracted made us (as Puerto Ricans) feel more relevant at least in the world of Astronomy. For us Puerto Ricans lovers of astronomy the news that /our/ Arecibo Observatory is being demolished is akin to having a piece of our hearts ripped out. Thank you so much for your words and for bringing attention to these sad news. My hope is that eventually it could be rebuilt... if only we had people who would fund it... Until then, Fly Safe!

Hello fellow SAC member! A couple of months before the pandemic hit we were able to make one star party there. Very few of us brought telescopes (I think it was only Juan, his family and I who did so) but to no avail it was cloudy all night. Nevertheless we had fun in the museum section and had fun admiring the telescope itself (we even saw the gregorian dome position itself to a target, I never saw that before) and I took a lovely picture of the radio telescope with all the clouds above it it lokked a bit gloomy but beautiful nonetheless. Now I see the meaning behind my foto, it was a farewell picture😥 and the whole event has taken a more somber and bittersweet aspect to it for me 😔. I bid farewell to this national treasure.

In fact I was told that's how it is for most of the old soviet science equipment. The government cared more about embezzling public money after 92 than continuing the countries scientific pursuits.

[@EdwardRLyons]

Not the accountants - the politicians. It's Congress' continual underfunding which caused the NSF to seek ways to offload the costs of running facilities such as Arecibo from its budget. So it will be no surprise if a full investigation will find that inspection and maintenance have been underfunded in the past 10 to 15 years. But any investigation is unlikely to follow the logic to the original root cause -- decisions made in the US Senate and House of Representatives.

Good job reporting on Arecibo. Maybe they can replace it with a phased array type? I'm an old iron worker, them cables become a problem without regular upkeep...

Unfortunately, I strongly suspect a phased array in place of the mobile secondary reflector would likely have the same if not more mass. If you mean an array of multiple independent dishes that's another can of worms. You can easily get a huge virtual aperture, but you won't have the same power handling capability.

[@Stralnikov]

Corrosion on the support cables was detected decades ago. At the base of each support tower, industrial blowers were installed. These ran full time blowing air inside of the cable covers, lowering the humidity to prevent/slow down the corrosion. The current scenario was contemplated before the installation of the blowers. The replacement of the cables was not considered feasible. Kudos to the engineering team and the local builders who constructed a marvel that withstood tropical weather, earthquakes, hurricanes, etc. for such a long period of time. The Observatory was the inspiration for many and a tool with many firsts. History can be a capricious lady, but the Arecibo Observatory will be remembered proudly.

I live in the tropics (Guatemala) I am very surprised it has lasted this long . to make things last in a tropical environment it is much more expensive. For example 316 stainless steel is considered a fairly good choice in many applications in colder climates , but to achieve approximately the same performance in the tropics you need something like 27-7 , but what is normally specified is 304 a less corrosion resistant alloy than even 316. So the tropics is a harsher environment combined with a lower standard of construction.

[@DjRjSolarStar]

316 has its primary advantages with high temperature corrosion resistance. Great for exhaust manifolds and tubing, but overkill for applications under 400 degrees F. I doubt the cabling they used was 304 even. Even under the worst conditions (my car exhaust), ive only seen 304 corrode superficially. I would bet they made those cables from the cheapest steel they could get their hands on, A36.

I do a ton of heavy industrial fabrication and deal with alot of stuff similar to this. Hate to say it, but yeah, demolish it. The problem isn't how feasible it is. This honestly looks like it could be fixed with current tech. The problem is cost. All this stuff to fix this is going to cost a huge amount. Not only that but you have decades of wear and tear on the whole things so you'd best replace alot of it while its down for maintenance. So while it's a repair they could do, they could probably build another one thats modern and without all of the maintenance issues for the same price as repairing the old one. In fact, so much stuff would need to be taken apart and put back together to do the repair at this point, it would just be easier to build a new one.

[@DrewLSsix]

In political terms though if it goes down it'll likely never be replaced, the sunk cost fallacy can be used to communities benefit in cases like this.

[@andrewtaylor940]

The problem is to fix it basically requires rebuilding it in it’s entirety anyway. They didn’t build in the ability to bring the platform to the ground. So they would, at a minimum need to strip out the dish completely. Put up a series of vertical supports and lift cranes to take the load of the platform and the cables. Detach the cables. Bring down the platform. Remove all of the cables and replace them. Likely also needing to replace/rebuild the towers. By the time you are done repairing it, there is nothing original left. You’d have to rebuild from scratch anyway.

@@tybofborg I’m not sure where discussions regarding Musk or Musk fanboyism came from. Certainly not from anything I said. I simply noted that in order to repair it you would need to demolish, dismantle, replace and rebuild 90%+ of it anyway. All of the cables need to be replaced. To do that the gantry must come down. To do that the dish must be removed. So the only thing left is the 50 year old towers. Bets on how good they look on detailed inspection? And most of this would involve lots of people working under the dangerously unstable platform and hoping the next cable break doesn’t drop it on their heads. The only things in it worth actually saving are the instrument and sensor packages on the platform. But getting them may be too dangerous. All of the rest is just bridge building. Probably better to rebuild those with newer materials and techniques. Past a certain age it is generally cheaper, easier and safer to simply demolish an older bridge and replace it with new. And much of this thing is basically repurposed bridge building.

I've worked on tram crews; that wire looks like z-lock which is often used for track ropes (the wire that the gondola is held up by, rather than the haul rope, which pulls the car back and forth). The bulge is from a core failure and if you see that, it has to be replaced. When the rope is intact, it retains the factory lubrication which prevents internal corrosion. Lightning is known to damage a few wires, and a certain number of broken or damaged external wires is allowed before it has to be scrapped. The sockets were poured with zinc in the old days, now they use epoxy. The end of the wire is inserted into the socket, which is a cone shape, and then spread apart, called a broom shape. Then, everything is cleaned and etched with chemicals, and then a particular kind of epoxy is poured into the large end of the cone. The socket joint rarely fails, usually it is the rope that parts due to breakage of the external wires or corrosion, when the failure is not actually mechanical. When a socket does fail, it's usually because the process was not followed correctly, or subsequent inspections did not discover that the rope was slowly beginning to pull out of the socket. Usually, a small wire is wrapped around the rope where it exits the socket and part of the periodic inspection is to look for movement right there. The rope has a finite life and it isn't cheap. It is usually built to order to length and can't be spliced like typical rope. You certainly can't replace it with the suspended load in place. Good luck, amigos.

This news saddens me tremendously. As others have noted, Arecibo is iconic. But let's note, what we are losing is the ANTENNA, not necessarily the entire instrument. If the observatory is laid out as I think it is, the antenna can be replaced ... perhaps with something better though not necessarily larger, and something easier and less costly to maintain.

[@planetfall5056]

Well the antenna and the truss/cable array supporting it is the most complex and expensive part, and if it snaps free or is cut down its going to demolish the dish as well.

[@CanalTremocos]

I think the problem is they don't have cable, or winches, in place to lower the antenna so they will have to crash it into the dish. Not even sure if there's a way to cut all the cables at the same time so the towers survive. Those cables are very heavy.

[@scout2nut]

yeah those cables from the 1960's are deteriorated bad, I work with winches and cranes and those cables are failing from the inside out, like a ticking timebomb they are going to snap

[@GusOfTheDorks]

@@TheEDFLegacy What you dont see in these pictures and what can be hard to see with the nakid eye at all is that these cables are getting stretched, contracting, and vibrating constantly. Temperature, ground vibrations, and wind will do that. Now, most of the time, these things have very little effect on what we use. The problem is time. It's been having this happen for decades. In some places in the cable it's going to weaken in. In other parts of the cable something called "Work Hardening" is going to occur. Basically the material is going to get harder, but brittle. This means it's alot easier for it to snap. Think of taking a wire and working it back and forth, how it eventually snaps. Same thing here, just on a larger and much slower scale. Now, keep in mind these cables are super thick and made up of a bunch of cable spun together. So they don't all fail at the same time. But once enough of them do, the snap is going to happen. Birdcage is a condition caused by this wear. I'm not 100% on how it happens, but it's one of the most obvious sign that things are going wrong since these not terribly flexible steel cords are starting to bend in ways they weren't designed. And like the other are saying, this deterioration is BAD. Like really bad. If you gave me these cables and asked me to do a lift with them, I'd first call you crazy and refuse to do it. These cables all look beyond the point of needing to be replaced and from a construction perspective you would need to replace all of them. That's not to mention the massive danger to the lives of the work crews these things would pose as they work on them. When one of these things snaps, it snaps with insane amounts of pressure. Assuming you could get a rig that protects from falls, when this snaps it's going to be like a whip made of tons of steel flying in a random direction. If it were to catch the tethers of the repair crews, they're dead. If it hits a repair man, that guy is going to die. If any chunks of it fly off, it's going to be like having a grenade go off in that it's going to be metal shrapnel flying at speeds typically only seen in combat situations. So you can imagine what that would do to anyone around. For safety and cost sake, just demolish it and build a new one.

[@nonfique429]

Thanks for finally letting me know what the name of that thing is. I'll start using that from now on.

[@juankenon]

would this have happened regardless of the original cable popping out? I assume these cables were rated for a certain number of years and the observatory is approaching 6 decades of service.

[@clubtepes2046]

I am honestly amazed, that they didn't design this thing, so that the instrument cluster could be lowered onto some hardpoints in the dish (possibly retractable if needed) for routine maintenance and upgrades to both the instrument cluster and the supporting structures.

[@EinhanderSn0m4n]

Great idea for Arecibo II in fact!

[@rpavlik1]

I wonder if it would just be too complicated/need even more overbuilding to be able to adjust the length of the cables. But yeah, some kind of service platform seems reasonable (from this non-expert) given that's a huge advantage of earth based instruments

[@stargazer7644]

They've never needed to do that in 60 years, and they've drastically changed the design since it was made. They regularly change out the transmitters/receivers at the focus without having to do that. What they should have been doing is replacing the original cables periodically. Leaving a bunch of steel cables supporting 900 tons in tropical weather for 60 years? Seriously?

[@ianlehman8342]

Its from the 60's, pretty much the decade when hindsight would have ever been the most helpful to the U.S. Pretty much everything done in the 60's was unsustainable, not going to last, or just plain wrong, with the benefit of hindsight But truly, as you say they never designed it with hardpoints in mind, it seems like this was made without forethought either, again like many things from the decade
