Has anyone attempted to find out what happen to the QR’s that are missing?  I have not checked to see if the numbers on YouTube match the ones that are on the Spacecraft Films DVDs.

These QR videos were, it appears, taken directly from the SCF DVD. This is not to say that they are bad, in fact you can learn a lot from sitting and watching them. The holes are likely due to the way they were researched. Each is the product of visits by the owner of SCF to the National Archives (et.al.) and actually "digging out" the individual films. It is a back-breaking process that takes A LOT of time and effort and often one finds that the next reel is simply not there. No reason, it is just not there. Happens in all archive hunts no matter what facility you go to. We're lucky he found what he found.

It is amazing how quickly the Saturn V went from design to completion, considering how the entire infrastructure had to be built for it at the same time.   Interesting QR's, but if these were taken from the Spacecraft Films DVDs,  should we be watching them on youtube?  Copyright infringement?

Depends on if Mark wants to press the issue. To over-simplify somewhat, he does not hold copyright to the material, just to the DVDs that he processed that contain the material. Now, if you were to start burning off copies of his disks and selling them, then he would be clearly infringed upon. However, someone who rips the material from his disk and posts it for free... well, you and I would find it as a violation, the court may not. By all rights he should contact YouTube and complain, but he's so overloaded with his own tar pit of projects, I doubt he'd take the time.

One YouTuber had 4 episodes from Mark's LIFTOFF DVD (Atlas) that have disappeared this year. So something transpired............

The original QRs were NASA produced and therefore public domain and should be safe for youtube. Any original content that Spaceflight Films added, though, would subject to copyright.

I'm sorry if I'm posting on the wrong thread here; please feel free to redirect me if I am.

I'm wondering if there were ever any plans to use Saturn V for anything other than human spaceflight applications of various kinds? This question arises from a documentary the I read last night of the limitations on energy that required the use of gravitational sling-shots to get the Voyager probes to the outer solar system in a reasonable time-frame.

Now, IIRC, the Saturn-V could insert about 70,000kg into LEO.  Even assuming that the J-2 was very inefficient, the third stage should have been able to push tens of tonnes through TMI or even TJI, which might have allowed for much more powerful probes (possibly even with a very small-scale NEP main thruster).  Was the Saturn ever considered as a launcher for flagship robotic missions like the Grand Tour and the Mars lander?

EDIT
I've just looked at the Titan-IIIE figures.  J-2 can't have been as efficient as the Centaur's RL-10 and they only managed to send about 1/5 of the IMLEO mass into a heliocentric orbit, so 5-10 tonnes tops for S-V through TMI.  Still would have given the engineers something extra to play with.

I couldn't find it with a brief search, but there used to be a wikipedia page outlining follow-on projects for the Saturn V, many of which were unmanned.  Apollo was part of the title IIRC.  Big telescopes, etc.

Edit:  Here it is.  http://en.wikipedia.org/wiki/Apollo_Applications_Program
