    Tom as a seventy year old Australian I have to say I am very jealous. I have seen the dish from a distance but not up close and personal. Given the number of pieces you have produced featuring heights I find your continued apparent discomfort rather interesting. Please keep producing this material. I really enjoy your work.

    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.

    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.

    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👌🏻

      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 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.

    • Me Here

      @Rob Fraser yup :) The way they did it was great though, as one of them looks up as they realise that & says something to the others "hey guys........ I think I know where it is" or something & points & they all look up & then the camera cuts to the moon in the sky. Probably doesn't come across in reading, but the comic timing in the film makes it really work :)

      The scene where they've lost the link with the rocket that's travelling to the moon & freak out becasue how are they going to get it back, cause the sky's WAY too big to scan to find the signal within the next few days, only to realise they can maybe narrow down roughly where to point the telescope to find the rocket is my favourite

    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. :)

      @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.

    Having recently had a similar experience when visiting the VLA (albeit with a static dish), I can thoroughly recommend it, if you happen to visit New Mexico at some point! Maybe you could do a climbing tour of landmark radio telescopes? 🤩
    And I can tell you, observing with these beauties is even more of a thrill. Best job in the world!

    Hi Tom,
    I love this video!
    I'm an insect migration scientist and every year we travel to the Pass of Bujaruelo in the Pyrenees to study the Autumnal insect migration. On some days we have upwards of a million hoverflies moving through the 30m wide pass, all using the sun as a compass and the wind to power their movements. It is a truly remarkable site and could be a fun idea for a video!

    My college project was the construction of a radiotelescope. During my research, I read alot about this particular radio telescope.
    I was successful in my project, the signalsI picked up wasnt very clear due to lots of interference but I was glad I did the project
    P.S I studied Industrial Physics

    I love the shot at 5:04 showing the *massive* counterweight that keeps the telescope balanced as it tilts over; it seems so impossible otherwise that it could tilt over all the way to the ground and not fall over, especially given (as he says at 6:38) it's not actually attached to the building!

  • Thom

    Tom, thanks so much for this! That gentleman's analogies w the feather and cell phone on the moon were extremely relatable. One thing that would help the video a bit, tho, would be to show a world map or map of Australia and show where this is located. I know where Australia is, but am fairly clueless about locations within Australia... Thanks!

    • DaveG

      A map would be cool, for places I don't know. FYI - The "Dish" is roughly 300km (180 miles) NW of Sydney (if you know where Sydney is).

    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.

      I'm not sure about every radio telescope, but there are some you can't even use cars with spark plugs around because the spark to start the combustion will get picked up. The Green Bank Observatory over in West Virginia has to keep a little fleet of diesel cars to navigate the grounds.

    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.

    There is a visitor centre here, but you aren't allowed to go up to, or into, the dish itself. So it's great to see this up close! (And it's still well worth a visit as a tourist to the dish despite these limtations)

    Tom could do a whole video about that PDP-11 system they're still using to manage the movement of that thing. It would be fascinating to see more about how its control is integrated to the outside world. Just the operations side of this is fascinating, then you get to the science stuff and 🤯
