I'm lucky to be just old enough to have watched the landing as an 8 year old, old enough to understand what was happening. The thrill hasn't dissipated at all in half a century. I love seeing others get all geeked and excited about it. Great video!
I really enjoyed the video Dave your explanations were easy to follow, informative and very interesting... great effort, well worth watching... Thanks.
The guy that was responsible for that worldwide network was a Welshman called Tecwyn Roberts from Anglesey North Wales, he was the first Fido in the Apollo program and pretty much designed the Huston centre
It seems a bit of a stretch to say Australia contributed. The Australians that have worked there, sure, but Australia as a country, not so much. The complex is funded entirely by NASA, not Australia's CSIRO. NASA spends about $20 million a year keeping it open. www.cdscc.nasa.gov/Pages/faq.html www.minister.industry.gov.au/ministers/macfarlane/media-releases/over-fifty-years-space-collaboration-between-australia-and
The funny way they converted the 10 fps SSTV to 30 fps NTSC in realtime. They had a special built machine that included a monitor and a camera filming it. The monitor was special in the way that the phosphors were much slower than on a regular monitor, this gave the NTSC camera time to record whole frames. The downside was increased motion blur that wasn't in the original footage. I wonder why they didn't rotate the video camera tube inside the camera, when they had to mount it upside down and tilted.
Because the camera was movable, and they used the same camera for the other part of the mission. After the landing, the astronaut used the camera in the right orientation.
The other replies are wrong. The reversing switch merely inverted the drive connections to the horizontal and vertical deflection yokes in the picture tube, thereby inverting the image.
Clifford: I don't think the previous answers are wrong, they are both plausible, especially the answer from ciano. I didn't ask how to flip an image on a CRT. I wrongfully assumed that the camera was permanently mounted upside down with a slight tilt, and wondered why they didn't just modify that camera instead of adding a switch to flip the image after it was received. By the way, after 9:50 mentions the scan converter switch and shows a picture. I know searched for "scan converter apollo" and found this interesting PDF: www.hq.nasa.gov/alsj/SMPTE-79-7-1970.pdf So the device I initially talked about is that scan converter and contained that switch to invert the image. Picture of the device is shown at 9:55 in the video and Fig. 9 in the PDF.
@@EEVblog It tells a interesting story that most people, including me, had no knowledge of. The rest of the coverage is regurgitation of stuff that most people "should" know.
I consider this among my favorite "feel good" films. Always leaves me positively buzzed. Even though it's taken a hit with Dave's revelations, I still love it. And not for least having Sam Neill play a sympathetic role for once!!!
The Honeysuckle folk I know had very mixed feelings about it at the time. It wasn't run by three NASA-trained monkeys, but by hundreds of highly expert scientists and support staff.
@@BentConrod The Parkes signal during the first nine minutes was coming from their dish, but not from the primary focus, because the signal wasn't yet above Parkes' horizon. Instead it came from the much weaker offset focus feed, and the picture was worse than Goldstone's, and much worse than Honeysuckle's. CSIRO has always been a highly political organisation (prone to lying about this) however, and it was only this year that the evidence forced them to come clean: theconversation.com/not-one-but-two-aussie-dishes-were-used-to-get-the-tv-signals-back-from-the-apollo-11-moonwalk-108177
There were 5 more missions to the moon and it is a pity that no one remembers the rest of the crews. Only the first who set foot on the moon. Great video anyways. Thanks for showing us the dish!
I seem to remember watching it at the time and wondering how they took the video of the lunar module taking off and tracking it up into orbit....and laughing to myself at the thought going through my mind that perhaps someone stayed behind...
What today's young whippersnappers don't realize is how difficult global communications were 50 years ago. There were a few communications satellites, very few, but no global network of satellites, and the bandwidth of those that did exist was very limited. There were undersea cables, but again many fewer than today, with much less bandwidth. If you wanted to make an overseas phone call, you had to book it in advance, and it was very expensive. I remember that a phone call from Florida to Israel in about 1973 cost about $9 per minute, which is over $50 in today's money. Even long-distance calls within the US sometimes could not be placed because all the circuits were busy. The systems NASA set up for their manned space flight projects were huge advancements, even though ridiculously primitive by today's standards.
Hours before the historical event taking place, everyone at HS creek are running around like headless chooks trying to get everything ready in time, then the prime minister turns up wanting to turn it into a PR stunt, and asks them to slew the dish out of the correct orientation for a bloody photo. I'd tell em to get stuffed. And p off, we're busy here. :P
Gorton wanted his spot in the sunshine. He got it - and will always be remembered for being a dick. Every Australian Prime Minister finds a different way to do that, except perhaps Bob.

I was 2 years old and still remember watching the launch from our front door. I learned a lot watching this video. Super glad you made it.
@Stephen Anthony The Southern Maryland Amateur Radio Club used to have access to a former DoD EME dish at the Navy's Cheltenham receiving station. Neither dish nor base are there anymore, though.

Interesting. when I was in college I handled data from DSS 43 on a fairly regular basis as well as Goldstone and Owens Valley. I'm a little surprised that the DSS 43 and 44 antennas are set up in the Cassegrain configuration. Owens Valley has mostly prime focus receivers on the 40 meter dish there. I actually had to climb up one of those struts to the prime focus once when we needed to swap out a receiver front end.

Thanks Dave for this excellent video, I was listening to a show with some "experts" about the landing on Swedish radio, could not make heads or tails, yours is really allot more engaging, factually correct and entertaining!
Traveling Wave amplifier, google it. [Correction, it was a klystron, a precursor to the TWT]. There were no transistors that could do S-band (2.2GHz) at the time, let alone power ones.
But how did they relay the signals - especially the TV one - around the globe when it was coming from a remote location like this one, or the ships and planes?
I met a English guy at a BBC talk in London yesterday who (with his colleague) designed the imaging parts for the cameras used on the moon. On returning to the Eagle, Buzz Aldrin pointed his camera at the sun and fried it’s internals. They built them for the British Military and let RCA use them. He wasn’t told what the parts were being used for until the launch.
He also pointed it at the earth from a low orbit / film set from the other side of the lunar module / prop to give the effect of the earth being a distant blue orb. But whatever floats your boat.
The biggest thing I learned from going through the Real-Time Mission Simulator was just how much of their time and communication was dedicated to just making sure they could communicate
it has been 50 years, really !!!!? feels like a century has passed ! people won't even gather around TVs anymore these days, to even see man's first steps on mars now.
The download speed for the telemetry was far above 2400bps. Command (upload) was slow (70kHz carrier bi-phase modulated) but telemetry data was huge, on a 1.024MHz subcarrier. I think the 2400 baud modem was decoding commands from Houston before sending it up.
That was an interesting tidbit. I work at the Johnson Space Center and have Mission Control access but never looked much into the space network. I had no idea there were so many radio stations to support Apollo but it makes sense.
Ah, that was nice, and a nice break for me. I'm currently embroiled with a bunch of Moon Landing deniers, and it's good to get a whiff of reality once in a while.
Even the Russians received the moon transmissions and admitted they had been beaten to the moon. What do your landing deniers say might be the reason for that admission?
@@CliffordHeath Their usual argument is that the Russians went along with the Americans because they didn't want the news about their own failures to be spread, or that they were getting huge grain shipments from the US, or that they are all in it together as the elite, the NWO, etc. The usual conspiracy theorizing with no bounds set by reality.
Unfortunately the video of the people from Honeysuckle Creek didn't touch on too many technical details. One thing that should be noted as to why the video was taken from California and not anywhere in Australia was because there was no satellite TV relay network back then to relay signals between continents. "Our World" was the first intercontinental TV broadcast in 1967, and the satellites used for it were oriented toward the northern hemisphere, so Australia was left out of the live event. In 1969 there was no satellite to relay TV signals from earth stations in Australia to the US, and undersea cables were configured for voice traffic, and their primary use was for the data modems that carried digital information to and from the Apollo spacecraft. Goldstone was the first place that offered a coaxial cable link (with booster amps every few miles) suitable for the bandwidth of the SSTV signal. Because this was how network TV was sent across the US at the time, the SSTV signal was converted to full-bandwidth NTSC there and sent as a standard NTSC picture over AT&T Long Lines coax to Houston. From there the TV signal was distributed to the press pool, and for US TV it was sent to network operations centers in New York, where it was switched into network programming and sent back out across the country. So TV viewers in Los Angeles saw a picture that had gone cross-country twice. No big deal when you consider that it had come from the moon!
False! I was talking yesterday to the technicians who operated the links at the time. The Australian signal was converted to PAL sent to Gore Hill in Sydney and was broadcast all over Australia (I was watching in Melbourne), but the raw video was also sent from the Deakin switching centre (in Canberra) to the USA and was converted to NTSC to be re-broadcast there just 300ms later. I have a photo (taken Friday with Stan Anderson) of me actually holding the commemorative plaque before it has even been mounted at the Deakin centre.
@@CliffordHeath Are you a silly nationalist who believes that Apollo 11 was an _Australian_ moon shot? 😔 Sorry to burst your bubble. I have already explained why your story cannot be possible, and you have failed to explain why it might be, so just name-calling has got you nowhere. Houston is in the USA, and it was fed by the Goldstone, California site. Whether you like it or not, NASA was and is the United States space agency, and NASA got its television feed from Goldstone. Where foreign media got their TV feeds is a secondary consideration.
@@StringerNews1 Page 16: www.hq.nasa.gov/alsj/ApolloTV-Acrobat5.pdf says "The television signal from Parkes was sent direct to Sydney Video, over a separate PGM micro- wave link, where a choice was made between the HSK or Parkes television signals as to which would be sent on to Houston via satellite." Still claim there was "no satellite TV relay network back then to relay signals between continents"?
My understanding is the Parkes DID receive the Apollo 11 signals on their Off-Axis Receiver as soon as Armstrong made the Circuit Breaker. At 8 minutes when Parkes switched to the main beam that was when NASA switched to Parkes.
"A lot of money back in the day..." One thing most people don't realize is that NASA contracts were "cost plus" contracts during Apollo. That meant unlimited+mandatory overtime. Some contractor's employees even when working locally were way from home for days or weeks at a time. The mantra was "Can you spend it faster than you can make it?" Some of us certainly tried.
You are wrong. It's certainly possible, there is just no incentive to spend all that money, and we'd have to re-do all the tech with modern components and systems. Although moon-fever seems to be happening again...
It would be much easier now with the computing power, simulation capability and materials science we have now. All you need is 20 billion dollars and you would have to retrain a few thousand people. That’s what happens when you shut things down for a generation. Knowledge gets lost.
Great to see Honeysuckle Creek getting the attention it deserves since the movie "The Dish" gave virtually no credit at all. The former Station Director of HSK during Apollo 11 was not impressed when he saw the movie. Tidbinbilla deserves a mention too.
I remember reading (or watching) a documentary claiming that they did not have the technology to capture a certain frame rate video coming from the moon, so they just connected a regular TV monitor, and directed a shitty camera to its screen. That was why the initial live broadcast of the moon landing had a terrible picture quality and no one was able to what was going on...
I know what you mean about the 'roo poo! They've been trimming my lawn this winter. It's covered in the stuff. I don't dare stray from the path when hanging out the washing.
Did not know there's an EEVdiscover channel as well, heading there and start watching thanks Dave. Btw been working around that area a few times and spot on can't even get out of your vehicle without stepping on the kangaroo poo.
I grabbed Andrew Tink's book "Honeysuckle Creek : The Story of Tom Reid" Dave is reading at the end. I had no idea Tom was a Glaswegian Elec Engineer like me. Available on Amazon Kindle etc.
When its decommissioned anyways they should give hobbyists access to it. Imagine what they could do with that thing! Don't just leave it standing around!
@@EEVblog I think more along the lines of a non profit running that thing. Offsetting the cost of preventing it from rusting away. (Think weird Hackerspace) I see this big antenna an immedeatly think: pipsqueak's big brother! (v=smWwjiOIAYI) a Community around that should be able to build a SDR for that thing or not? Probably without a sending functionality, but still. I pearsonally sadly have very few knowledge of radio stuff though I plan to try recieving data from wether sattelites.
you will tell us anything everybody knows that thing was built so the Ausies could order in their larger back in the day (they also had the first refrigeration to keep it cool) its a bush to brewery com.... lol nice vid Dave thanks mate
My parents thought we should see the landing and first steps in color... so we went to a neighbor's house, they had color TV. Turns out it was in B&W! Our TV at home would have been better, color sets were much more blurry at the time. Also, I remember the confusion of whether the picture was upside-down, or actually, on its side... I remember the picture, but I don't remember being able to tell what I was looking at (I was 11). Still, great time to be alive... my childhood consisted of the Beatles and the Space Program!
Thanks Dave, I did not know how detailed and involved efforts were necessary for the transmission of the moon walk. As the late newscaster Paul Harvey would say...." And now you know THE REST OF THE STORY " ! J K

He also pointed it at the earth from a low orbit / film set from the other side of the lunar module / prop to give the effect of the earth being a distant blue orb.
But whatever floats your boat.
Really nice video, Dave. I enjoyed. Thanks for sharing.
Thank You EEVblog!
Thumbs up! :)
Indiana USA.
The biggest thing I learned from going through the Real-Time Mission Simulator was just how much of their time and communication was dedicated to just making sure they could communicate
What a great story- thanks
Awesome! Didn't knew any of that, thanks!
it has been 50 years, really !!!!? feels like a century has passed !
people won't even gather around TVs anymore these days, to even see man's first steps on mars now.
Love the Total Recall shirt
The download speed for the telemetry was far above 2400bps. Command (upload) was slow (70kHz carrier bi-phase modulated) but telemetry data was huge, on a 1.024MHz subcarrier. I think the 2400 baud modem was decoding commands from Houston before sending it up.
"A switch that made history" Now that's exciting...imagine a single tactile button switch making history!
worth using a proper toggle switch instead of that tactile pshbutton garbage!
Great video Dave!
That was an interesting tidbit. I work at the Johnson Space Center and have Mission Control access but never looked much into the space network. I had no idea there were so many radio stations to support Apollo but it makes sense.
Nice effort for getting all this info, good stuff, thank you
Hi. Just wondering how they got the high quality video footage of the lunar module taking off from the moon?
Aaaah! Great completing info Dave!
Ah, that was nice, and a nice break for me. I'm currently embroiled with a bunch of Moon Landing deniers, and it's good to get a whiff of reality once in a while.
Even the Russians received the moon transmissions and admitted they had been beaten to the moon. What do your landing deniers say might be the reason for that admission?
Clifford Heath mental retardation doesn’t have a cure.
@@CliffordHeath Their usual argument is that the Russians went along with the Americans because they didn't want the news about their own failures to be spread, or that they were getting huge grain shipments from the US, or that they are all in it together as the elite, the NWO, etc. The usual conspiracy theorizing with no bounds set by reality.
Thanks Dave!!! Your'e the best.
Nice one Dave...looks like ya having the time of ya life!
Unfortunately the video of the people from Honeysuckle Creek didn't touch on too many technical details. One thing that should be noted as to why the video was taken from California and not anywhere in Australia was because there was no satellite TV relay network back then to relay signals between continents. "Our World" was the first intercontinental TV broadcast in 1967, and the satellites used for it were oriented toward the northern hemisphere, so Australia was left out of the live event. In 1969 there was no satellite to relay TV signals from earth stations in Australia to the US, and undersea cables were configured for voice traffic, and their primary use was for the data modems that carried digital information to and from the Apollo spacecraft. Goldstone was the first place that offered a coaxial cable link (with booster amps every few miles) suitable for the bandwidth of the SSTV signal. Because this was how network TV was sent across the US at the time, the SSTV signal was converted to full-bandwidth NTSC there and sent as a standard NTSC picture over AT&T Long Lines coax to Houston. From there the TV signal was distributed to the press pool, and for US TV it was sent to network operations centers in New York, where it was switched into network programming and sent back out across the country. So TV viewers in Los Angeles saw a picture that had gone cross-country twice. No big deal when you consider that it had come from the moon!
False! I was talking yesterday to the technicians who operated the links at the time. The Australian signal was converted to PAL sent to Gore Hill in Sydney and was broadcast all over Australia (I was watching in Melbourne), but the raw video was also sent from the Deakin switching centre (in Canberra) to the USA and was converted to NTSC to be re-broadcast there just 300ms later. I have a photo (taken Friday with Stan Anderson) of me actually holding the commemorative plaque before it has even been mounted at the Deakin centre.
@@CliffordHeath Are you a silly nationalist who believes that Apollo 11 was an _Australian_ moon shot? 😔 Sorry to burst your bubble. I have already explained why your story cannot be possible, and you have failed to explain why it might be, so just name-calling has got you nowhere. Houston is in the USA, and it was fed by the Goldstone, California site. Whether you like it or not, NASA was and is the United States space agency, and NASA got its television feed from Goldstone. Where foreign media got their TV feeds is a secondary consideration.
@@StringerNews1 Page 16: www.hq.nasa.gov/alsj/ApolloTV-Acrobat5.pdf says "The television signal from Parkes was sent direct to Sydney Video, over a separate PGM micro- wave link, where a choice was made between the HSK or Parkes television signals as to which would be sent on to Houston via satellite." Still claim there was "no satellite TV relay network back then to relay signals between continents"?
My understanding is the Parkes DID receive the Apollo 11 signals on their Off-Axis Receiver as soon as Armstrong made the Circuit Breaker. At 8 minutes when Parkes switched to the main beam that was when NASA switched to Parkes.
Awesome
"A lot of money back in the day..." One thing most people don't realize is that NASA contracts were "cost plus" contracts during Apollo. That meant unlimited+mandatory overtime. Some contractor's employees even when working locally were way from home for days or weeks at a time. The mantra was "Can you spend it faster than you can make it?"
Some of us certainly tried.
Superb video ! Great edu value - can’t wait to share with my 10 year old son - thank you!!!
Just awesome stuff Dave. Love it
50 years ago it was possible to land on the moon but not now....isn`t it strange?
You are wrong. It's certainly possible, there is just no incentive to spend all that money, and we'd have to re-do all the tech with modern components and systems. Although moon-fever seems to be happening again...
It would be much easier now with the computing power, simulation capability and materials science we have now. All you need is 20 billion dollars and you would have to retrain a few thousand people. That’s what happens when you shut things down for a generation. Knowledge gets lost.
Great to see Honeysuckle Creek getting the attention it deserves since the movie "The Dish" gave virtually no credit at all. The former Station Director of HSK during Apollo 11 was not impressed when he saw the movie. Tidbinbilla deserves a mention too.
Neil Armstrong wasn't impressed either! and said so in a letter he wrote to the Honeysuckle crew. I show this in another video on EEVdiscover.
Awesome Dave, I camp out there regularly as the hikes are great in the area. Did you check out Orroral too?
Didn't even have time to scratch my butt :-(
EEVblog hehe, spewing, another time maybe... It looked like a good trip though!
Keep on dishing, Dave! Love it!
I remember reading (or watching) a documentary claiming that they did not have the technology to capture a certain frame rate video coming from the moon, so they just connected a regular TV monitor, and directed a shitty camera to its screen. That was why the initial live broadcast of the moon landing had a terrible picture quality and no one was able to what was going on...
No, it was a scan converter. See above.
God Bless America Long Live the Republic and Yunz down there to.
Thanks Dave, this is far more better than any moon landing deniers research has done (which is limited to what they can find on google)

Great information and presentation, thanks for sharing.
I know what you mean about the 'roo poo! They've been trimming my lawn this winter. It's covered in the stuff. I don't dare stray from the path when hanging out the washing.
Did not know there's an EEVdiscover channel as well, heading there and start watching thanks Dave. Btw been working around that area a few times and spot on can't even get out of your vehicle without stepping on the kangaroo poo.
I grabbed Andrew Tink's book "Honeysuckle Creek : The Story of Tom Reid" Dave is reading at the end. I had no idea Tom was a Glaswegian Elec Engineer like me. Available on Amazon Kindle etc.
When its decommissioned anyways they should give hobbyists access to it. Imagine what they could do with that thing! Don't just leave it standing around!
Apparently it was very expensive and difficult to maintain operation of it. You likely can't just "give access"
@@EEVblog I think more along the lines of a non profit running that thing. Offsetting the cost of preventing it from rusting away. (Think weird Hackerspace)
I see this big antenna an immedeatly think: pipsqueak's big brother! (v=smWwjiOIAYI) a Community around that should be able to build a SDR for that thing or not? Probably without a sending functionality, but still. I pearsonally sadly have very few knowledge of radio stuff though I plan to try recieving data from wether sattelites.
So, who will be the first on the moon 4 real?
Super interestingly Dave...many thanks.
Wasn’t the Apollo tv camera an SSTV camera considering the low frames/second count?
you will tell us anything everybody knows that thing was built so the Ausies could order in their larger back in the day (they also had the first refrigeration to keep it cool) its a bush to brewery com.... lol nice vid Dave thanks mate
Great job! I very much enjoyed this video.
I did enjoy that. Thanks Dave
My parents thought we should see the landing and first steps in color... so we went to a neighbor's house, they had color TV. Turns out it was in B&W! Our TV at home would have been better, color sets were much more blurry at the time. Also, I remember the confusion of whether the picture was upside-down, or actually, on its side... I remember the picture, but I don't remember being able to tell what I was looking at (I was 11). Still, great time to be alive... my childhood consisted of the Beatles and the Space Program!
The original road up to Honeysuckle looks "a bit how are you doing?" as you say :)
Thanks Dave, I did not know how detailed and involved efforts were necessary for the transmission of the moon walk. As the late newscaster Paul Harvey would say...." And now you know THE REST OF THE STORY " ! J K
There is a lot more too!
