Saturn seperation
« on: June 23, 2016, 08:25:03 PM »
Hello guys  :D
Does anyone of you know footage that shows the stage seperation from the Saturn rocket family besides the famous stage sep footage of Apollo 4 ?
I know that I saw footage from another flight a long time ago and also saw today some footage that presumably shows an Saturn I stage seperation in Bob Fitch's video "1964 History of Spaceflight in RSS / Project Alexandria-11 / KSP 1.0.4" at 4:17min from his Project Alexandria Youtube series ( a great series by the way if you are interested in the history of spaceflight that uses KSP for visualization).
However I couldnt locate any footage yet and hope that some of you know more about that.

I know other footage exists, but I'm not sure right now where to find it.  Not all Saturn Vs were instrumented with film cameras.  The second-stage ullage burn (as seem from the discarded S-IC) is the distinguishing visual factor -- 3 at 120-degree intervals versus 2 at 180-degree intervals around the circumference.

Just to be clear you are asking about space-based footage not telescopic ground-based footage of the separations, correct?

Yes footage from the rocket itself during flight.

The documentation says this is from A 6, but I can't confirm that.

If you're referring to the famous clip of a S-IVB pulling away, that's not from a Saturn V, so it can't be from a S-IC. It was at the top of the S-IB first stage in a Saturn IB launch. The upper stage with the 3 ullage rockets was the S-IVB-200, the S-IB model without restart capability.

Thank you, but I forget to include that in my first comment.  ::)
I am searching for footages apart from the seperation that was filmed from the 2nd stage that I already mentioned in the first comment as well as this footage in the quote that shows the seperation from a S-IVB stage that was filmed from the jettisoned stage.On the internet you can't really find any other footage except this two famous shots, but I know that there were more than that.
The film that I mentioned in my first comment shows an S-IV stage with 6 RL-10 engines, so the footage comes from a early Saturn I launch.

Apollo 4 and 6 both filmed the separation - I did a piece on the weather in shot of both of them :)

The famous shot of the separation looking upwards was AS-202.

The Mighty Saturns has Apollo 4 and 6 (as well as all the other Saturn V launches).

Apollo 4: "Three separate views, including TV feed and camera pod footage showing first stage separation."

Apollo 6: "Four different views including TV feed, two tower cameras and footage from aboard the spacecraft."

The second section of the Apollo 4 video (the S-IVB separation sequence) is mislabeled. It is NOT from a Saturn V, but from a Saturn IB, specifically AS-202.

It usually is :)

I looked at the weather formations visible at the end of the sequence as it tumbles and tracked them down to a view over Florida on the date of AS-202's launch, which matches exactly what should be visible at the time of separation.

I can't remember which clip I'm thinking of, but I wager you're right.  The key point being that the number of ullage rockets tells you which model of the S-IVB you're looking at from the spent stage.

Apollo 6



Thanks for the Apollo 6 video - that was particularly interesting, given its, er, interesting S-II trajectory.

Could someone please explain what the red plot from about 2m58s represents? And was that being replayed at normal speed or was it sped up? Also, the image from about 6m15s of the CM moving from left to right: was that an animation or did they also have a camera on the SM watching the CM separation? (I assume the former.)
