Saturn V anecdote
Discussion
I don't know if this has been mentioned? How the F1 engines were ignited:

I didn't realise they fired in a sequence. Fascinating.

Check out this video about the Saturn V's Launch Vehicle Digital Computer (LVDC).
Made by IBM, this was the rocket's flight computer, which controlled it until it reached the moon.

I don't think it controlled the Apollo spacecraft all the way to the moon. It was to control the trajectory of the Saturn V during launch, initial orbit and Trans Lunar Insertion. It was discarded together with the SIVB stage of the Saturn V once the Command/Service Module and Lunar Module disconnected from the stack and headed off to the moon. Guidance to and from the moon was controlled by a computer in the Command Module. A similar computer was in the Lunar Module and this could be used for trans-lunar navigation too - as was the case during Apollo 13 when the power to the Command Module had to be almost completely shut down due to the disabling of the Service Module.

It controlled the S-IVB to impact on the Moon, so it is technically correct to say it controlled it all the way to the MoonSlide set from a lecture showing lunar surface photos which have been colour corrected to show what the Apollo astronauts actually saw ( instead of the rather washed-out scan s previously available ) - showing just how orange Jack Schmidt's 'orange soil' actually was

Amazing if accurate.https://gsa.confex.com/gsa/2018AM/webprogram/Hando...
If you look at the TV images of the site, you can see the orangey colour. But it doesn't show up that sharply on TV.

That is rather strange. The colour guides (gnomons) were brought back to earth so there was a clear colour indicator present in the laboratories. Also, samples of the orange soil were brought back too so there would have been actual samples of the material (kept in airtight boxes) to examine.
Having said all that, a lot of the Apollo material has still not been properly examined - and modern examination techniques are a lot better than what was available in the early 1970s - so new revelations from these old samples are still possible.
I too would like to know why it took so long for the true colours to be revealed.
The discovery moment was captured on TV although the orange colour isn't that obvious in the TV images. Note that Schmitt says that the orange colour is similar to the colour of the "LMP Decal" on his camera. That should give a very accurate first hand comparison as to how the orange looked to them at the time.

The Sun should leave.Interesting comment heard at a royal event. Sun reporter telling the chief plod that he had to leave now (traffic movement block in place). Police head honcho says non. Reporter starts to tell the Chief of police that is from the Sun and needs to leave now. Head police fella says "don't care if you are from the Moon, you are not leaving"
If the Saturn V still existed, there would have been no need for the ISS. We could have had mega Skylab type space stations made up of docked SIVB stages.
Where are they getting their top speed data from? The Saturn V was capable of propelling 30 tons away from the earth at 25,000 mph.

To be fair, The Sun is another one of those "newspapers" that if they had a front page headline "Sun to rise in East tomorrow!" I'd be tempted to get up early and check...Where are they getting their top speed data from? The Saturn V was capable of propelling 30 tons away from the earth at 25,000 mph.
