p.s. I remember that you were asking about what content should you upload on main channel and what you would upload on another one. IMHO the perfect would be to have "short version" as "short reviews" on the main one and longer versions on the other channels. Some of this videos i wish to watch in longer version but not all of them. Although i wish to be informed about all the clips you are putting out there at least in short.

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.

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.

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.

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.

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 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!

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.

Great video Dave! Really interesting. Now, if money were no object, and seeing that it's no longer used, wouldn't it be great if they could move the dish back to it's original location, plus of course give it back it's original looking tripod in the centre. Would cost an absolute fortune though. But at least it's been preserved at it's current location, rather than simply being demolished once it's service life was over.

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.

ARIA was pronounced Arr-righ-ah, and they had twelve or fourteen of these "Snoopy" planes (maybe not all at the same time though?), which used to be parked in "the dog pound" - so said Stan Anderson during my 60 minutes conversation with him. He was the fleet commander, not just "an operator".

The Dish is good, too. I was wondering where you were, like 'where is Dave? That's not Parkes?' Now I have learned - Canberra is fucking dry even in winter.
Did NASA really go to the Moon on the first try?
