| I always love this video, and I have been a lifetime dedicated fan of James Burke, but few seem to note that the whole segment didn't have to be timed as there is a cut shortly before the launch. If I recall either James or one of the producers talked about it once. They knew they had to start the last bit 13 seconds before launch and had practiced it repeatedly. At 13 seconds to countdown James nailed it. I'm sure even after practicing it I would have stumbled over a word in the clutch moment! |

| It would appear that this was the Titan IIIE which launched Voyager 2. They would have had another chance to get the shot about two weeks later when Voyager 1 launched. (Due to quirks of interplanetary orbital mechanics, Voyager 1 got to Jupiter several months before Voyager 2 despite launching second). The IIIE did indeed have a Centaur stage with a "thermos" full of liquid hydrogen and another with liquid oxygen, but that's not what we see in this clip -- the pillars of fire and smoke come from a pair of solid-fuel boosters that burn for about two minutes, followed by about six more minutes of flight powered by two more stages burning non-cryogenic liquid propellants (hydrazine and nitrogen tetroxide) before the Centaur was ignited. |

The reason is that you can think of a "launch window" as really a specific ideal launch time, but a little earlier or later will also work, although being early or later would result in arriving at the destination later. They aim to launch the first spacecraft right at the opening of the window, so if there is any delay they won't run out of time. If it launches "on time", then it actually launched early for the launch window, and takes longer to get there. The second launch right after then launches closer to the actual ideal launch date. | |
| ▲ | anonymousiam 3 hours ago | parent | prev [-] | | Decades ago, I worked a mission that went up on a Titan IV, and I spent a few weeks at Pad 41 working in the IUS clean room. Riding up and down the tower in the rickety (self operated) elevator was frightening. Walking the gantry and looking out at CCAS, you could see for miles in all directions. Standing under the thrust cones was an amazing experience. Unfortunately, no photos were allowed because it was a classified mission. All I got were a few stupid tee shirts. About 15 years earlier, I had done some work at the VAB and walked around the Saturn IV that was laying on its side there, just as James Burke had a few years earlier. It wasn't there when I worked the above referenced mission. I'm not sure when they moved it, or where it ended up (but it's not in the "rocket garden" at the Visitor Center). | | |
| ▲ | dotancohen an hour ago | parent [-] | | Do you mean a Saturn IV-B? Those were the third stages of the Saturn V. If so, the complete Saturn V was displayed horizontally outdoors for quite a while. I was in the US in 2018 and stopped by KSC too see a Falcon 9 launch, by then the complete Saturn V was in a building. If you mean just the Saturn IV (no B), that was the second stage of some early Saturn rocket. I don't know much about those or if one was ever on display. |

| Cuts from the speaker to some background footage, then back to the speaker, are a very useful technique. They can be used to lie, too, of course (cut from the interviewee's face to the interviewer, then back to the interviewee, and you can cut out context that changes the meaning of what was said). But when used with no deception in mind, they can really enhance a powerful moment. And this was a perfect example of it: no deception at all, just a wonderful visual image that makes an impact on the viewer. |

| ▲ | hoppushoppard 32 minutes ago | parent [-] | | I was amazed by the perfect timing. I realized, if you listen closely, there is commentary audio feed from the launch with countdown. So knowing, the engines starts 3 seconds before liftoff, he was able to time the speech. I saw this clip dozen of times, and only after keeping attention I realized this. So with the cut technique, it seems like seamless feature, and that's the magic of the TV.
Nevertheless amazing delivery. |
