Also remember that the signal coming from Voyager is so weak that they can barely receive it with those massive dishes, and the communications back are done using multiple hundreds of kilowatts of power, sent via the same dish, and the spacecraft will only get them more than 24 hours later, and reply also 24 hours later on. Also the voyager spacecraft were never actually designed to last that long, they were actually spare Mariner spacecraft bodies that got a massive antenna grafted on to allow communications, then a RTG instead of solar panels, and thus were sent out. Now down to a little over 200W of power for use on the spacecraft, so by around 2030 they will no longer have enough power left to transmit high speed data, and soon after that will lose all transmit power, though the computer will continue to operate, and keep the spacecraft aimed at the sun for decades afterwards, but will be mute.

@@davidioanhedges Yes it is small, but by the standards for the Mariner probes it was based off it was huge, and the error correction was designed to be as robust as possible, but also as simple to implement in the spacecraft as well, as complexity at the time came with added mass, and you had an overall maximum launch mass you could not exceed. Thus the panels were made from Beryllium aluminium alloy, milled as thin as possible in low stress areas, and milled away completely where not needed, just to avoid the mass of a rivet to hold a gusset in place. Remember at this time digital decoding was done using discrete chips, or using massive computers, so to put the error correction and forward error correction in the probe they had to choose between robustness, data rate and mass, choose one, because mass is the severe limit. Even the digital data recorder was special, because it had to survive in a vacuum, and it still does work now, that design and the tapes are still holding up.

No sophisticated technology reaches a state of complexity until it becomes indistinguishable from magic. Anyways, have a look at the concept of Fundamental Constants. You'll be amazed at the precisions in Creation. Everything in the Universe is determined by special forces called fundamental constants which are unbelievably precise. For eg. -: If the rate of expansion of the Universe would have changed only by just one part in a quintillion after the Big Bang, a quintillion is one with 18 zeros after it, 1,000,000,000,000,000,000, the Universe would have continued to expand or collapsed back on itself. How the Atmosphere (various layers) protects the Earth from destruction from meteorites is again amazing. Solar Flare which occur frequently from the Sun ☀️ has energy equivalent to 100 billion Atomic Bombs which was dropped on Hiroshima couldn't destroy Life on Earth 🌍 due to Van Allen Radiation Belt. The centre of gravitational force could have existed anywhere on the Universe which is supposedly 13.5 billion Light Years Big but it only exists at the right place that's why Life is possible. Scientists say, if it is shifted/ moved even 1 inch compared to 13.5 billion light years length of the Universe, the effects would be catastrophic & it would wreck the Universe. So, everything is on the knife edge.

"The Dish" is one of my favourite films. It's awesome to see Tom wandering around Parkes, and to see that they must have filmed a lot of the movie in the actual structure. The telescope is an amazing piece of kit.

A lot of the film was shot in Forbes, as it looks more like a 60s town

@@boredincan Forbes and Parkes used to be very similar towns 30 km apart but Parkes reopened gold mining in the 1990s and has grown in population and wealth as a result while Forbes is sleepy. Parkes is also a rail junction for east west trains and one day a north south line when it's completed. Forbes does have some gorgeous architecture however well worth the look. Forbes is also prone to flooding from the Lachlan River as it did in 2022.

John has such a great Aussie way of explaining very technical details understandably. Thanks for a great segment Tom and Jack.

The effect of switching back and fourth between the guide and the dish slowly lowering Tom down was brilliantly done.

That jumping off the dish at the end is funny, I love the idea of using an enormous telescope as a quick and dirty elevator

@@roberine7241 Agreed. I used to work at Arecibo Observatory (which Tom Scott has also visited), and lugging equipment up there was an absolute pain. Things in the hundreds of kilos could be lifted by winch, but that wasn't worth the setup overhead for things in the 20-50kg (50-100lbs) range. Those we ended up hauling by hand.

There was previous video that had a similarly enthusiastic and informative expert guide Tom was interviewing although I cannot remember the exact details. I think it was maybe a waterworks or bridge-works?

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!

Great film, though many of the elements to make the film are invented. And some of the aspects are borrowed from another Australian telescope at Honeysuckle Creek. But you would struggle to shoot at Honeysuckle Creek. It is long decommissioned.

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.

this is an absolutely phenomenal video that perfectly showcases the level of care and dedication and attention that goes into these highly specialist fields, and i dont mean to undercut that at all, but i cant silence that part of me that wants to make a titanfall 2 reference

When Tom said "a film that was shot here more than 20 years ago" I went out in search of a movie made in the 80s, saw the film made in 2000 and thought "huh, they must have remade it then" before my temporal awareness kicked back in. *double facepalm*

Nice on Tom and CSIRO team. Well done keeping the dish in top shape!

What an awesome presentation by John! I can learn a lot about talking on this episode.

The gent giving the tour deserves a payrise, he was great!

I could listen to John talk for hours, this is definitely my favourite so far. I think this is what I love so much about Tom's series - completely normal people who are experts in their job and still have plenty of enthusiasm to share their passion

I grew up watching 'The Dish' and even got to visit Parks as a kid (too young to remember much about it though unfortunately). I've always wanted to ride on it. Tom, you're living my dream!

That end shot was very cool. Nice little video - thanks 👍🏼

People like Jack are so important for their science communicating abilities. The feather demo, the explanation about a cell phone on the moon, these are things that seem so simple and obvious, but is really a lost art in many scientific communities.

I always love those "all you have to do is" moments of ingenuity and engineering. This structure is packed full of them. Thanks for the ride !

'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!

John is so knowledgable you can really see how passionate he is about his work. Incredible interview!

As someone who's had to polar align a star tracker for astrophotography I can appreciate how they just kind of did it once for this and built it in instead of doing to coordinate calculations. Also this is just mind bogglingly big. Like it doesn't make sense from this perspective that the dish just sits on rollers and doesn't fall over. Awesome video!!

I love the pacing of this video- intercutting Tim’s journey along the dish with all the background on the telescope leading to him going to the dish was an excellent choice :)

That was just brilliant Tom!

Being an RF engineer that worked at a step site like this but with a 72 antenna; this was my favorite video so far. Absolutely perfect.

The radio quiet discussion reminds me of the time I was at Onsala Observatory in Sweden and they'd recently fixed a couple of recurring problems by getting a nearby farmer to turn off his electric fence and removing the microwave oven from the staff room.

Fun fact: There was once an amazing high power signal discovered by the Parkes team, however it was simply from one of them using the microwave at the wrong time.

I was there a few months ago. I was blown away by the size of the telescope and amazing astronomical contributions it has made.
