@@45eno No, the dish is a reflector and tuned to reflect 90% of radio waves into the gregorian dome and onto other antennae. Nothing to improve. The receiving equipment was top notch state of the art - or as much as they could afford.
@@45eno If they do decide to replace it with an entirely new Arecibo 2.0, the only difference would probably be structure and design improvements (maybe a total redesign) to help the new telescope survive better in natural disasters like the earthquakes and hurricanes that seem to hit the island often.
Arecibo was a technological marvel. We oooh and ahh over smart phones and tablets but Arecibo was so much more. I wonder if we'll ever have the intelligence, let alone the financial will, to build something like this again. The RF, mechanical, & electrical knowledge is something many people don't find interesting. Without Arecibo, we're so much more blind to the Universe. Great video and RIP Arecibo. I hope we build another like you.
Arecibo was superseded by other projects quite fast. In the 80's, arrays of telescopes became much more sensitive than Arecibo. Arecibo's main advantage was that it could also TRANSMIT radio waves, it could image passing near-earth asteroids. Arecibo's demise is not a huge problem for observers of the sky. It is a technological marvel - for the time (60's). Not so much anymore.
@@user-rf2ey8ub4d But it cannot transmit radio waves. That was Arecibo's big plus. It could image passing asteroids and bounce signals off the moon for distance measurement.
They have a special version of this tour for GoldenEye 007 fans. Lasts only 2 minutes and 42 seconds and ends with you escaping on a helicopter as the whole facility explodes. Then everybody gets magical gold-plated Walther PPKs that can kill anybody with one shot. Awesome tour.
I could never have imagined that the "flying antenna" contained so many things. Hard to realise that absolutely everything we see in the video is down today. Each step, each room, each computer. nothing doesn't exist anymore. Thank you for this footage, you've been so lucky to go there and what a great idea to share it with everyone. RIP Arecibo (and RIP my good english, sorry !)
This is just incredible footage! I can just picture Sean Bean as Alec Trevelyan in that cable car firing at 007 with the assault rifle. Interesting, Pierce Brosnan had a stunt double do most of his scenes on the physical antenna due to his fear of heights. I don't blame him as this is very high up. Thanks for posting this video.
This is such a good tour video! It includes all the good things. Lots of stuff to dive deeper into if one feels like it. I am glad you got to experience this incredible up close. Thank you for sharing!
Having seen the footage of the collapse and knowing just how weak and worn out the structure was, any recent footage of people out on that platform makes my skin crawl.
I can't believe they got to climb all over that thing. Seems incredibly dangerous. I had no idea what that structure looked like close up. Shame it couldn't be saved.
I visited it twice. I remember it was very scary to look at it, specially thoes long cables holding everything in place. This place was an incredible technological achievement. RIP Areicbo Observatory.
This is one of the best videos I've ever seen. It's really neat to see how this place looks in depth and up close. I always wanted to visit this place. I watched Goldeneye when I was 10 years old and I'll never forget it. I remember my dad telling me it was a real place in Puerto Rico. It's very sad that it's gone now, but it will be remembered and it's preserved in a few films and video games.
Imagine being inside it when it collapsed. It's lucky they knew it was badly damaged an no one was up there. Imagine if it had gone suddenly without warning with people working up there
The sucker was damaged beyond repair long ago.. its looked ragged for a while. I thought it was retired long ago. Was shocked to see it had just fell.. thought it was gone long ago..
It had about 30,000 views prior. I just made the mistake of clicking the "safe for kids" option on my channel not knowing it would remove the ability to comment. It also wiped my entire comment history.
At about video time 2:50, the workers talk about 12 strands of one of the main support cables being broken off as a result of the hurricane in January 2015. Could it be that the degradation of the cables was known about back in 2015, and was not concerning enough to have caused a full scale investigation??? The worker did said that the facility was shut down for a while, but if they had been more concerned and had fully investigated, could they have formulated a plan that would have prevented the eventual future destruction?
Thanks for posting this! As they were transmitting on 430 MHz we could not tour the platform during our filming for the RUclips documentary "An Insider's Tour of the Arecibo Observatory - 07 July 2011". Sadly, the severe damage caused by Hurricane Maria leaves the future of this facility in doubt. - KP4MD
I notice how the dark area on the image becomes slightly grainy @ 13:50, is that due to close proximity of the radiation source like the transmitter? RIP Arecibo...
I was searching for awhile for video/imagery of the inside of the Gregorian dome and this was perfect. The most striking thing to me is the waveguide system, which is very extensive. Had no idea that one ran all the way down the catwalk to an outbuilding. That's a lot of waveguide. Sad we lost this amazing piece of scientific machinery, and dare I say, artwork.
it makes me wonder how they shot Sean Bean's death scene without actually having Sean Bean fall down that height... it's a shame that it collapsed...:(

American measurements For British viewers: 1,000,000 box of cereal: 1.2163 square km 2.6 football fields: 435 m 7,000 cheeseburgers: 2 metric tons 80 tanks of gas: 3,000 liters
terrifying that that rotary joint wasn't (unless that was cut or i missed it) locked out while they were in it. imagine if that warning siren went off while you were stuck!
Most radio telescopes are passive ones that only receive as far as I know this was the only one that could transmit radar. Seems like it's loss will make it a bit more difficult to know what may or may not hit us.
Great, so this was used to detect asteroids that might hit us, and now it's destroyed. So do we have a replacement? I haven't heard of it. They need to rebuild Arecibo bigger and better than before!
@@electricheartpony yeah. But they broke at 60% of their calculated strength.... would be interesting if either the math was wrong or the cable-company saved on the material?
I stopped watching this as she said "boxes of cereal" WTF is wrong with the US measurement system? I'm pretty sure everyone using the metric system gets a general idea of how wide 300 meters is... This isn't meant to insult anyone, I'm just struggling to understand the insistence of using a very bad measurement system.
From what I gather from others in the Radio Astronomy business.....chances for a new Arecibo ver 2.0 is currently somewhere between nil and zero. Things and opinions can change. Political leaders in D.C. change. Leaders in acidemia and NSF also change over time, and so do their opinions. I'll bet that if some credible evidence ever pops up about an actual Earth-Asteroid collision, I bet lawmakers will jump out of their shoes to get something built, and rite quick!! Some have wondered if the new, larger antenna in China (FAST) can take over in the search for Earth crossing bodies. But nope. It isn't capable of doing so. There is some rumor that the GBT in West Virginia has been testing low power transmission, but that is operationally some years away IF it can happen for real at all. There is rumor that if anything will ever be built in place of the Arecibo antenna, it will likely be an array of much smaller dish antennas configured in an interferometer kind of lash-up. In any case, the Arecibo site is now little more than a place where local school children can study the meaning of radio physics. 😮💨
In memory of a truly amazing scientific experiment.
I always wanted to visit here. Even just to have a look from the side of the dish. It's too bad I can't do that anymore. I really appreciate this tour.
I have a feeling it will be rebuilt
@@monoamin_ With the funding that wasn't enough to maintain it while it was aging? I hope you're right, but I wouldn't hold my breath
Great tour! A shame it is lost but nothing lasts forever. Fifty Seven years is a good run! Would be nice to build a entirely new one in its place.
Not getting maintenance for 10 years on the cables is a problem.
Makes you wonder if better tech now comes from a swimming pool size dish.
@@45eno No, the dish is a reflector and tuned to reflect 90% of radio waves into the gregorian dome and onto other antennae. Nothing to improve. The receiving equipment was top notch state of the art - or as much as they could afford.

I got recommended this just a couple days after the collapse.
because it became trending, everyone had to look up what this arecibo thing was
I can't believe they got to climb all over that thing. Seems incredibly dangerous.
I had no idea what that structure looked like close up. Shame it couldn't be saved.

Thank god nobody was on this on December 1st..
This is an amazing structure. 😢I wish I could have seen it in person.
I have played alot of BF4 around this dish, both on and under it, we will miss it!
damn snipers on the towers, lol
Thank you so much! What a tour.
It breaks my heart its gone.

I never realized how actually big this was till now. Wow

That sound beyond 12:32 sounds like the heartbeat of Arecibo, that mechanical sound. That sound is forever stilled, and I will miss this observatory.
That's a badass radio. I can only hope they construct an even more badass telescope in it's place.
naa, we gonna build a bigger one out in space :D
Wow!!!.....Always found this place interesting!!!!............loved the video, but a little spooky knowing that it fell!!!!!
20TW ERP... I want one! Interesting stuff, thanks.
Amazing, talk about outside of the box. I think my head just melted 🤔😳🥵🤯
It’s a shame it fell, but I appreciate this great tour/documentary. It gives such a great perspective on the massive size of Arecibo.

Whenever this telescope was brought up in the astrophysics lectures of my course, somebody inevitably asked: "Does it go underwater?"
We knew one day it would fail, I guess hindsight is always 2020!
i wish i couldve visited arecibo and gotten a tour like that
after seeing what happend to it i am glad i didn't do it. never trust hanging structures. i know the chances of them collapsing are like one in over a million but i dont care xD

HOW IRONIC THAT THE ODD INSPECTION COULD HAVE SAVED ALL THIS DISASTER!!!
I thoroughly enjoyed that 73 peter from barry electronics KC2MMA
"They inspect the tracks for cracks... they haven't done that in awhile."

Even talked about the actor Pierce Brosnan who rolled down the Stairs when he was attacked by Sean Bean.

Maybe they knew they were clear? I don't see any reason to believe it has such a function.
Came here to see what this structure was used for
Most radio telescopes are passive ones that only receive as far as I know this was the only one that could transmit radar. Seems like it's loss will make it a bit more difficult to know what may or may not hit us.
It wasn’t the only one that could transmit. Greenbank also has a powerful transmitter, but it is a smaller telescope.
" Not anymore ! " - Chief Inspector Clouseau
Glad no one was in it when it collapsed. Perhaps the salvaged parts can go to a museum.

long as they keep on top of the maintenance schedule, should all be fine :)

Arecibo didn’t detect asteroids, but it characterized asteroids that were found by other dedicated search telescopes. There is no replacement.
@@stargazer7644 That's why they said "rebuild".
I don't why it would be useful nowadays but I really want this thing rebuilt, I feel sad it's broken
Very cool video.
All of the people on that tour must have taken a HUGE sigh of relief knowing now that the cables broke at only 60% of the force they were rated for...
They were rusting and deteriorating since the 60's
And a cable had already given out
Lop everybody’s old Arecibo videos gaining new views again.
So NASA looks to Arecibo to see if the asteroids they detect will hit the earth. Now who do they go to for that information?
こんな複雑なものをよく空中に建造できたな！？凄いね！！

RIP great antenna
for england james?
No... for me.
when cable strands were snapping they should have added more cables
It’s not that simple. It snapped AT the anchor. Where you going to tie off additional cable to?
