- The Arecibo Radio Telescope is one of the most famous astronomical observatories in the world, and for a long time was the world's largest. On Monday night a support cable snapped and fell into the reflector dish, damaging the reflector panels, it also crashed into the side of the gregorian dome which includes the secondard and tertiary reflectors.

Sorry aliens. “The number you are trying to reach has been temporarily disconnected. Please hang up and dial again.”
Too soon, bro. 😞
Because quarantine has officially begun. Safer that way, wouldn’t want to pollute the galaxies.
Bastards were calling collect anyway.
how do you know they use Western Electric Model 500 telephones?
What's the point of trying to communicate with aliens when reality is a simulation? Why create multiple sentient species within contact distance when you know that they will interfere with each others evolution and progress?
Well, I just learned more about the AreciboTelescope in 12 mins. than I have in the last twenty years. Great topic choice with many interesting asides about the telescope I've not read elsewhere. Thanks, Scott.
Same. I recall a (I think) Veritasium video a while back where he actually visited and talked with one of the scientists, but IIRC he was more focused on one specific experiment/observation they were doing there at the time than the facility itself.
Tom Scott also has a good visit video
Well said, William.
Indeed. I've been aware of this thing since Jodi Foster phoned home in the 90s, and hear about it on a semi-regular basis, but never really KNEW much about it. Thanks Szyzyg!
@@andrewlavey6992 Thank you. Scott is very much my go-to guy for all matters related to space flight and its environs.
Scott Manley: This is a brand new episode
BF4 Players: Hey I've seen this one before
There are going to be alot of BF4 references. We don't even need to watch this video. We already understand what happened.
The cool thing about Rogue Transmission is that it is supposed to be the Five hundred meter Aperture Spherical Telescope (FAST) located in China, but it wasn't built before they made the map, so they took inspiration from Arecibo. So the map is pretty much the Arecibo telescope transplanted in FAST's location lol
just google when battlefield 4 was set
something very messed up is happening in the universe right now
I also was like, hey this happened in BF4 haha
deadass when I saw the thumbnail
"Now you might think that a cable snap would cause the structure to fall, luckily engineers are smart."
I can't look at the Tacoma Narrows bridge being blown down by wind and think engineers are particularly gifted.
Not all engineers are created equal.
Looks like the maintenance crew did not have an engineer! ;-)
@Philip A smart engineer will always include redundancy. Failure is a fact of life. All things will sooner or later fail, expected or unexpected. This proves that the redundancy was necessary.
@@topixfromthetropix1674 Don't blame the engineer entirely. He very well could have pushed for redundancy, but his budgeting department gave him the shaft.
As a ham radio guy, I just love Arecibo Observatory.
Joe Taylor, who got his nobel prize in Physics for work at Arecibo, once pointed the Transmitters at the moon, and the reflected signal was so strong on earth, people with a small antenna and a handheld radio were able to talk to him, from half of the planet.
They may have been able to listen to him, but not talk to him, hey? 😉
@@nagualdesign No! The aerial is designed to pick up very, very, very, tiny signals. It can hear a lot.
@@nagualdesign That's the nice thing about ultra high gain antennas like the Arecibo telescope: It works both ways. If you are able to hear someone, and have the same power transmitter as them, they will probably be able to hear you as well.
People with only 1-2m long Yagi antennas and less than 50 watt transmitter power were able to communicate both ways.
@@sadiqmohamed681 Have you ever used a handheld radio? They don't transmit anything!
@@nagualdesign he is talking about a handheld transceiver (transmitter & receiver, usually referred to as HT or handheld by amateur radio operators). The Friis transmission equation being what it is, as long as the antenna gains and the path loss work out, then Arecibo can hear even a low power transmission from a handheld transmitter.
I saw the articles on FB and thought I'd just wait for Scott's video lol
Good call 😉
IFLscience had a good article but Scott is more enjoyable to watch
Same
When it comes to space news, I ONLY listen to Scott Manley or Tim Dodd. These guys know their stuff!
Yep! Me too, one can always count on Scott to clear up a vague story!
my recently deceased cousin, Dr. Ray Jurgens used this telescope to make Doppler images of Mercury and near earth asteroids . He also worked a team that rebuilt the Goldstone radio telescope. I've been reading some of the published research because Mercury made headlines again with the discovery of organic molecules in the atmosphere...its kind of sad that 2020 will have taken my cousin and this very valuable instrument.
The cable was snapped by a guy who shoot it in tank thinking he was in BF4
"LEVELUTION"
The game is set in 2020...
Guys they made Rogue Transmission into a real thing omg.
Can't wait for the Siege of Shanghai
FoxTail737 ITS HAPPENING
Kinda doubtful that you'd get a tank up there. Evidently you've never actually been there.
I came here to say Battlefield 4's Rogue Tansmission levelution event.
yes correct

HAHAHAHAHA!!! I was thinking the same thing .... they reached the Evolution...
I miss that game... loved that map
I always wondered how accurate bf4's map was.

Who rpged the cables
Somebody snapped the cable to take down the Fantan chasing him.

This comment’s so good haha
I got little birdie legs.
dip dip potato chip
Honestly though, if I ever worked there, also knowing about battlefield 4, I would've shouted it and then be concerned.
It was a combination of damages from Hurricane Maria, the earthquakes that hit our Island in the last year and also lack of maintenance and funding.
Good! I hope another earthquake hits Puerto Rico! Hopefully a 10.5!
As a puertorican space nerd, this made me cry. Still does. I really hope it gets fixed.
My dream house it's a house, on the top of a hill, looking down on the observatory's dish. :-(
i am a puertorican space nerd too, i no longer live there, but i have gotten up close to it before. i hope it gets fixed. :(
If you get this house, please don’t use WiFi

How about a house somewhere outside the tropics, with a long, narrow balcony sticking out over a huge parabolic mirror (with a drain hole in the centre)? You could lean over, look down and see amazing things. Just remember: OUTSIDE the tropics.
@@Sableagle Just don't point it at the sun, might make a focused death ray and burn whatever it is pointed at.
Typically the cables will fail at that point due to corrosion. They require periodic maintenance and inspections, as well as greased to prevent corrosion. They also have a finite lifespan, if they stretch too much eventually they'll snap. I've dealt with similar cables on guyed towers of 1500 to 1800 foot heights. Most of those towers when they fail often are due to corrosion on guy wires. I'd be doing some emergency inspections on the remaining cables, especially any installed at the same time that cable went in. Could easily have been a defect in manufacturing that might exist on other cables.
Scott is suggesting that the wire-end, however securely it seemed to be potted by its geometry, appeared to have simply popped out of its socket en masse.
@@-danR That only happens if it was defective, overloaded or corrosion caused a failure. All the more reason to inspect the rest of them. Normally the cable fails before the sockets do if it's overloaded, so I would think defect or corrosion are more likely the case.
@@andycanfixit
I'm looking at the contractor's catalog (Muncy), where they include Arecibo among their works: "Our Projects Speak For Themselves" p. 13.
Yes, looking at the photo of the Spelter Socket without any cable, it is reasonable to expect that either the cable pulled through (highly unlikely) or that corrosion right where the cable 'exits' the socket (not uncommon) was sufficient to cause the cable to fail.
An interesting post today on LinkedIn by Herbert Weischedel
, owner of an NDT company, showing the failure of the IWRC element of a cable that did not show any particular visual evidence of markers to be concerned about.
@@rs2352 That does not surprise me. Depending on the cable size and equipment either ultrasonic or x-ray are the only means to inspect the cable ends. When in doubt a cable will be replaced and destructive inspection done to see how bad it may be. I am sure that end will be dissected and I would not be surprised if it has heavy corrosion in it.
The cable broke because it's 2020.
it didn't break, It slipped through
@@TylerDWard yeah, because it's 2020
That Telescope was radiating the Earth anyway, (my theory) so I’m glad it’s broken, lets see how the rainforest responds
@@TylerDWard True that. Ever since it got broken, my cuppa tea takes 3 whole seconds more to heat up. That's the amount of heat this telescope was radiating. I think the rainforest will evolve a sort of vegetative blanket to stay warm now that there is less radiation from that telescope.

When they fix it can they also get a pressure washer after that grime? In fact, I have a pressure washer, I'll get her done.
That's the spirit!
That is what I was thinking. If they provide me with a flight and a place to sleep and some food I would clean that right up for them.

I learned SO MUCH of that Radio Telescope of PR from this video, than all the years I've spend living there. Thank You so MUCH for keeping your videos AD free.
Hey Scott, just want to say i REALLY appreciate all the high-quality content you drop on your YT. Always looking forward to the next video! Greetings from Norway
I am hearing a lot of people saying that Arecibo was made obsolete by the new FAST telescope in China. This is *not* the case. FAST may be larger, but it lacks Arecibo's radar capabilities, and its design makes it impossible to upgrade it to an active radar instrument. This means that observations of Near Earth asteroids, which are important to determine their risk to Earth, can only be made by Arecibo.
(Sadly, the only other radar instrument in the world that could observe asteroids, Goldstone, is also offline since last year due to a damaged klystron.)
Also (and I don't know this) but if its pointing in a different direction, then it will always add some value even if its not unique?
Also, new, larger instruments don't make the old ones obsolete most of the time. Telescope time is rather restrictet and another, bigger instrument means more time for students on this one.
@@mirwurscht7515 Absolutely! This is true for optical instruments, and it is also true for large radio telescopes, of which there are so few.
And bimblinghill is right, the two telescopes are on opposite sides of the Earth, adding to their complementary value. Not all observations are time critical, but some are.
Well, we also have NEOWISE at least
As far as the western world should be concerned, Arecibo is the only radar telescope of any value right now. No one should trust or do any business, research, or science with the Chinese CCP government.
Awesome seeing a video about my islands telescope from Scott Manley! My friends works there and posted those pictures when the accident occurred. Very sad.
Boricua represent 🇵🇷🇵🇷
Scott, this was one of your best videos. Amazing. I listened to any any single second.
Always glad to see your updates and learn more. Thank you
The fact that it's so hard to get this one-of-a-kind gift-to-science funded is a source of national embarrassment for the U.S. Both political parties used to brag about how much they were spending on science. We've fallen pretty far.
Well, simple fact is it has been obsolete for decades now. Technology doesn't sit still and nostalgia doesn't get much Federal Funding unless its for a political museum or somesuch.
@@fortusvictus8297 A reflector dish is a reflector dish, and this is a big one. The tech that made SINGLE LARGE dishes obsolete are electronic advancements that allowed phased arrayed multiple SMALL DISHES to function as one large dish. Still, there are disadvantages to that approach.
Next year someone will come up with a novel CHEAP active material that reflects AND amplifies radio signals that could be coated onto existing dishes which will make SINGLE LARGE dishes in demand again, but . . .
@@dr.floridaman4805 well when everything is privatized it's more expensive for the consumers while the 1% gain from it.
That's why medicine which is super cheap to produce (sometimes just a couple dollars) sells for thousands of dollars.
The mUh FrEedUm sounds very romantic but it doesn't work because companies always have the priority to maximize profits no matter what.
@@fortusvictus8297 Oh, are there some other, newer, sexier telescopes somewhere else that are just drowning in government funding?
@@dr.floridaman4805 Privatization disincentivizes scientific discovery because innovation is only pursued if it could make profit. Most of the scientific discovery that we have now would never have existed because there would be no one to fund it. Privatizing science would be a terrible idea.
The world is starting to look more like a Battlefield game. Seeing these images is giving me BF4 flashbacks.
I was thinking the same thing, I sat on those towers and sniped down on people. Also walked the cables like a tight roap
BF4 is set in 2020 as well. Abandon all hope lol

Thank you Scott for taking the time to create this upload.
I am sending them $100. Especially since I have watched dozens of videos and never been asked to visit Patreon or hit the "like" button. Thanks Scott!
The funding comes from sales royalties of the movies Golden Eye, The Losers and Contact.

Great episode! Many thanks for the wonderful background plus operational details. I've always found this structure fascinating. Cheers.
Thanks for the update, Scott!
It is an iconic image burned into everyone's mind when they think about radio telescopes & deep space.

Until next time my friend,........

Regarding the ionospheric research motivation to have Arecibo built:
The math was correct if you neglect collective effects between electrons and ions (so-called incoherent scatter, or non-collective Thomson scatter). The insight gained by subsequent experimentation (and the antenna used for this was massive, just not as big as Arecibo) was that if you use a wavelength larger than the Debye length of the plasma, you see the ion motion embedded in the electron scatter (collective Thomson scatter) and the received power is concentrated into 10s of kHz of bandwidth instead of MHzs of bandwidth for non-collective scatter. More power in less bandwidth means the signal to noise ratio is higher, so you need a less sensitive system.
Bill Gordon and others did a lot of fantastic work. It wasn't a mistake in his math, but a discovery by others as part of the scientific process.
Scott, I'm a fellow space enthusiast and work with incoherent scatter radars. If you ever want to chat about them let me know!
Scott, thanks for including inches and feet to what was germane to the story. It kept the story tempo moving and engagement with you sharing your story. Thanks for including me in sharing this interesting story

Considering its importance, I've often wondered why it hasn't been awarded something like a UNESCO designation.
Didn't save Palmyra from the barbarians
Because for people that decide those things, science is something that is not important.
@Mark Hepworth New World Information and Communication Order
Wiki: UNESCO has been the centre of controversy in the past, particularly in its relationships with the United States, the United Kingdom, Singapore and the former Soviet Union. During the 1970s and 1980s, UNESCO's support for a "New World Information and Communication Order" and its MacBride report calling for democratization of the media and more egalitarian access to information was condemned in these countries as attempts to curb freedom of the press. UNESCO was perceived as a platform for communists and Third World dictators to attack the West

Honestly I don't think so bc you could look at earthquakes at a reason why it failed. I mean do we know how this kind of machinery does with constant tension on it from earthquakes?
We successfully prevented them from intercepting a message from our alien space base.
Didn't get by me. I was wearing my aluminum foil hat. I'm on to you...
I was just thinking this is the kind of thing you'd see as a fake news clip in the opening credits of an asteroid or alien invasion movie: "The Arecibo Telescope was damaged today..." Next up is unexplained power failures in major cities.
Everyone thinks the hats only purpose is to keep "them" from reading your mind. But it's other purpose is to intercept signals of this nature as well. I could teach you a thing or two.
Having lived in PR, I can tell you that the lovely trade winds also bring in the salty sea breeze.. I would be surprised if corrosion wasn't a factor.
had not heard about this incident til now. Arecibo has always been fascinating to me, ever since I heard of "The Arecibo Message" mentioned on the old PBS children's science show "3-2-1 Contact".

Coming back to this video the day after it totally collapsed. This is heartbreaking.
We watched a documentary on this telescope on laser disc in the early ‘90s in middle school.
Ah nice the good ol Laser Disc, a technology both too early and too late
Scott here, trolling the flat-earthers by talking about a spherical reflector being made of flat panels.
Ugh...heartbreaking. This is in my hometown. I remember taking my aerospace engineering major, German college roommate to go see it in late 80s. He was fascinated. Good memories. Hope they can fix it.
My wife and I ended up taking a cruise that boarded in Puerto Rico. They had "shore excursions" you could take, and I insisted on the trip to Arecibo to see this thing in person. You can't even imagine the scale of this thing until you stand near it and gaze upon it with your own eyeballs. I was standing in the observation area on the rim of the reflector, admiring the feed suspended in the air. And while looking at it, I saw these small little green things sorta bolted on the side. And then I realized those little green things were large HVAC chillers, like you'd find on the roof of a data center! That really helped calibrate the scale for me. That feed suspended out there is essentially a multi-story high building suspended on cables!
The guy doing the tour noted that there's very active management of those cables that are on large reels. As the temperature changes, of course the dimensions of those steel cables also change and they have to reel cable in and out to keep the feed in the correct position.
There's also a number of stories where the transmitting capability of this antenna was used to recover spacecraft. I think I remember reading about one amateur radio satellite where there were two conflicting modes - the transmitter in one mode could be on the same band as a command receiver or something, and the transmitter would desense that receiver, and normal commanding wouldn't work because of this. The solution? MORE POWER. Put a kiilowatt transmitter on a zillion dB (well, what, maybe 30db? I dunno) antenna and just brute force your way into the receiver.
I think it was also used by the group to try to recover that one spacecraft that was in solar orbit, and where NASA no longer had the equipment to transmit commands to it. Some SDR hacking later + lots of dB of antenna gain -- got them much of the way there.
What an amazing resource for the US, and a shame we can't invest the relatively tiny amount of $$$ to keep it operating. When I had visited, I believe at that time much of the funding was via the NSF, with Cornell as the "operator" of the facility. I sure how we can find a way to support this literally one-of-a-kind resource for the future.
They should open a GoFundMe to repair it. I'll chip in a bit.
It's sad that things like this require public funding while our government spends several hundreds of trillions on weapons of war and death. I'd pitch in too though!

Regarding the Spelter Socket and potential failure mode of the cable, suggest you take a look at a video posted today on LinkedIn by Herbert Weischedel
.
This makes it clear how a cable could deteriorate to an extent that causes it to fail without exhibiting many of the 'telltale' characteristics one looks for.
Being on site, anyone with a reasonable amount of experience working with cables of this nature would be able to state with a degree of confidence if this were a 'pull through' event or corrosion at the scoket.

The same technique is used in the Elevator industry to support elevator cables its called a Rosebud. the end of the cable is unwound (after being secured with ties to prevent further unwinding.) the ends of the strands are bent over and put into the center of themselves forming the "Rose" flower assembly. this is slid down into a cone shaped metal cone. then melted Babbitt is poured into the rose to solidify. and capping off the end of the cable then the assembly is attached to the car./ or what ever device being used.

30 years ago, I was working with a man who had worked on the construction of the Arecibo Radio Telescope. I remember looking through his photo album, and I wish I had a few of them to share now. Before the current dish that we know today, there was a grid of wires that covered pretty much the same footprint. My friend told me that before they could build the dish we know today, they had to clear the vegetation from the valley, and that it was infested with snakes.
Thanks Scott...!
I sincerely hope that they get the Aercibo Observatory up and running again soon.
considering its completely destroy because it wasnt even funded enough to keep in shape, I doubt theres any money to rebuild it
@@Veikra We can hope though.
"As you may have heard..." Nope, I don't hear about stuff like this until I hear it from Scott Manley.
Scott; Back in the late 70's I was in Puerto Rico (Navy) and 4 of us biked across the island from San Juan to Ponce. We decided to ride across the north coast and stop at Arecibo. When we arrived we found the obligatory locked gate and signs warning anyone to keep out. While we stood there debating whether to move on, a car came down the road and we moved aside. The man in the car asked what we were doing? We just wanted to take a look at the telescope. He said sure and we followed him into the site. We got to walk under the dish. It was interesting and we got to see the control room. We thanked him profusely and rode back and finished our trip, then returned to San Juan by bus. Still remember looking at the dish in awe.
This was way more trivia-packed than I was expecting, going in. 👍
No one:
The BF4 player with a SRAW: haha missile go BOOM
do you know that on 1. December it will collapse and destroy everything
@@LukaArtelj I didn't know what you meant until 5mins ago when I found a article on it. So no, I did not know. Thank You
I'm sorry, I can't help but be very distracted by that launch tower accompanying your LEGO Saturn V. Please explain yourself, where'd you get it / did you build it / where's the design?! O_O
Might be the one posted on LEGO Ideas
Yes do explain yourself! It looks like the cheap chinese knockoff version of Valerie Roche's design, which disappoints me endlessly. I would've thought structural integrity and accuracy of the model would be important to Scott. Guess I was wrong. Also Vonado are dodgy man, support the designers!
Tom Scott and Matt Gray have an excellent video about their visit to Arecibo, well worth a look!
Scott: In case you hadn't already found this out, to your question at around 11m25s: "... to, I believe, the University of South Florida?"
- It's UCF, the University of Central Florida (Orlando).
Their website had a brief article & a picture of the damage, seen from the ground under the dish edge, posted on Aug. 11, the day after it occurred.
Thanks for much more info on this than I had already seen; it fills in most of my curiosity gaps about the incident.
Hearing about this saddened me, reminding me of July 2004, when some friends & I visited PR, and saw this awesome facility in person!

When I heard "1000 foot wide" my immediate thought was "blimey, that's as wide as the Enterprise (1701 refit) is long...
I live 40 minutes from this radio telescope and it’s really sad but it will be fix soon
Wepa!
This not age well
Noooo! This place is so cool, I hope that they will be able to repair it and get it going again. I want to visit this thing one day.
I have no idea what this guy is talking about but I love the passion in which he speaks about this subject
