Great video! Any chance you could upload the full video of you riding the dish? Would be kinda fun to just see the whole thing.

So a Dish of this kind is commonly referred to as a Telescope is it? Since When? & Why?

How the dish at that angle doesn't rip off from the building is quite interesting

There's a huge counterweight on the other side to keep it balanced.
Big Video Energy
How it doesn't rip of the building is the counterweight. At that angle the the counter weight ensures all force is still downwards. Without a counterweight it would fall off the building because the force would be sideways.

Can we all just take a moment to appreciate how good of a guide John is? Presenting technical (and quite elaborate) information in an easy to understand manner, coupled with little quirks and bits of trivia about the facility without skipping a beat. I assume he has done this many times, but wow! A round of applause!

The film John refers to is called ‘The Dish’, and was made in about 2000. It’s a great movie, one of the last Aussie films that showcases Aussie larrikinism and wit. Great video, Tom!

I’ve worked on a couple of programs about the dish, in 1984 and 2000, and apart from being able to crawl all over the structure etc, the most memorable part for me was chatting with the astrophysicists working there over dinner. Their descriptions of deep space etc blew my mind.
There's something about spending time among people with planet-sized brains which simultaneously makes you feel smarter but also makes you feel very basic. :)

Highly, highly, HIGHLY recommended everyone watches "The Dish" from 2000 (starring Sam Neill and Patrick Warburton) -- it's a comedy movie about how a town in rural Australia was chosen to transmit around the world the images from the 1969 moon landing, and the technological challenges they faced way back then. Aussie humour and cinema classic👌🏻

It wasn't until the last 10 seconds that it actually hit me what "tilting the dish towards the ground" meant. For _several_ minutes, I was like haha, Tom's gonna do camera magic and 'hop' off the side of the dish. Just holy cow, the SCALE of this thing (and the building) is so… difficult to fathom.

Having been aware of this telescope because of the fantastic film The Dish, I never quite realized the scale of the thing until you were walking around just under it. Nor did I think when you said "...to touching the ground" I didn't ever think that meant quite literally. Absolutely amazing it can do that!

The way you had the feeling that you couldn't tell whether you were moving, or the dish was moving, or the sky was moving... I experienced something similar a few months ago when I took an engineering tour of the very honorable Mt. Wilson Observatory, located high above Pasadena, CA. Though built well over 100 years ago with parts that had to be lugged up the mountain by mules and very primitive Mack trucks, when you're in the 100" observatory dome and they turn the dome you think the telescope is turning, not you, the observer, on what you think is a unmoving platform. It's only when they open the outside door and you see that trees are moving by do you realize what's really happening.

illitero 14 日 前
There are a good few videos like that, and I'm assuming a good portion has to do with a natural sense of balance and footing taking a more subconscious place in the mind since more focus is on placement/aiming of the shot itself. So when things go wonky and Tom is allowed the resources to get fumbly and worried, the camera operator's greater focus is on keeping Tom framed and likely holding back laughs haha

As a radio astronomer, I was so happy to see this video! There really is nothing like going up into a dish - I've been on the Efflesberg radio telescope. I've never observed with Parkes, but I have with another Australian telescope, ATCA (they're both operated by the same institute). It's an amazing feeling when you're observing remotely from the UK, and knowing that you're responsible for such huge things turning and looking at astronomical objects for you. You might be sick of radio astronomy now, but you have got an invite to Jodrell Bank Observatory in your suggestions submission form! Come say hello next time you're up this way. :)

@David Lowery epic
zyeborm 13 日 前
@Jett Nash in short yes. In longer form kinda. The satellites operate on different frequencies mostly to what is being observed and in some places starlink is turned off around the telescopes. If you take a look at their coverage map you'll see a big missing circle in western Australia. That's over the square kilometre array that's being built there. It's much more of an issue for optical astronomy. SpaceX are at least working on it now and all of their future satellites are to be at magnitude -7 so they should be invisible to the naked eye. It'll probably help by not totally flooding the optical sensors but it'll still get in the way probably.

One small step for Tom, at the end! I'm not just taking a phrase from space lore in a silly way, I genuinely thought from the beginning that Tom not wearing a harness and relying utterly on correctly repositioning himself to avoid tumbling to disaster was crazy risky. Then it was revealed how the curve lines up with the ground at full deflection wasn't so bad.

I believe the entire instrument was designed by Barnes Wallis and part of the genius of the design is that clever cantilevering means that when the collector is tilted from vertical, instead of it distorting under gravity, the redirected forces actually tighten up the focus.

Fun fact: this is the telescope that picked mysterious radio signals at random times during daytime for 17 years. Then they were finally able to identify the signals: they came from a microwave oven in the facility. Source: The Guardian - Microwave oven to blame for mystery signal that left astronomers stumped
As a deep sky astrophotographer, this is one of the videos I’ve understood the best! Really cool to see. I used to visit Goonhilly a lot as a child and the dishes there were so amazing to see, almost ominous figures. Equatorial (and Alt-az) mounts are really fascinating the way they work and are essential to what most astronomers now do. I timelapse my telescope setup pointing at the night sky a lot, but I think most people don’t quite realise they move at an incredibly slow speed making a timelapse necessary to even see the movement.

The amount of energy the feather expended when it struck the floor is more energy than has ever been collected by every radio telescope ever” what a mind boggling comparison!

Went here on a trip a few years ago and it was fantastic. Always a nice surprise seeing one of my favourite JPvidrs visit a place I've been.

'The Dish' is one of the greatest movies I have ever seen and I am honestly so jealous of Scott for being on site. Genuinely fascinating vid! Bravo!

Seeing an “old” Apple Xserve / Xraid rack still be used is very interesting!

I'm so stoked that other people get to see how dope our country is; The Dish is a genuine Aussie icon

@Westerly Winds I can see where your coming from there, he does sound a bit South African.

Oh I thought it was in South Africa. The guy with the helmet on sounded South African to me.
✝️ LORD JESUS DIED & ROSE AGAIN TO PAY THE DEBT OF UR SIN! ✅By Faith in the sacrifice God has made are we saved from the penalty of sin! 🔵Turn from your sin that leads to death & accept His Gift that leads to eternal Life! 💜We are all sinners that need God. No one can say they are perfect to be able to pay their debt of sin. This is why only God could pay the penalty for us, that is merciful Love!

6:58 Star trackers in missles used to work like this, except for the constant rotation thing - they instead played a tape of were a reference star is supposed to be as a function of time.

Great video Tom, this feels surreal because I live only a hour away form the telescope and visited it multiple times.

As an Aussie, I need to let you all in on a little secret: John the Dish Wrangler might love his job, but he would have been really keen to see the end of Friday afternoon so that he could go home and sink a few tinnies with his mates. Signed: Mick, A guy who also loves science and works in a pathology lab at a major hospital… also doing a science every day 😊

If anyone is wondering about the film that Tom mentioned that was filmed here, it's called "The Dish" and it follows the story of tracking and receiving radio/tv signals from Apollo 11. Cracking film! Great video Tom!

@dr2okevin You mean the Australia Telescope Compact Array in Narrabri... It was a very exciting time when that happened.
