Unfortunately the separation was under less than ideal circumstances for the service module. It immediately lost control and was later fired.

There was a few Apollo missions where the Service Module became a hazard during re-entry. It got a little close to the Command Module. They finally figured out how to do a separation burn of the 4 RCS quads to push it much further away.

My big concern with the space guillotine is that it was one of those mission critical things, like the LM ascent engine that if it failed, it was pretty much a LOV situation at that point in the mission. I'm curious how rigorous the testing was for the mechanism.

A guillotine? That's pretty edgy. But when you think about it, it's actually a pretty sharp idea. It would really slash the time taken to separate the modules. I'm glad nobody lost their heads when that was used. I guess using connectors just wouldn't cut it. It's a neat way to slice through the design complexity. And it's so simple. I bet it put a knife through the production cost. Is this mechanism shown in a museum anywhere? I think I need to stick my head in it.

A fabulous explanation! I grew up in the 1960’s so I remember part of the Mercury program, all of Gemini and all of Apollo. I knew about the guillotine that was used to separate the ascent stage from the descent stage on the LEM, yeah, to me it’s still The Lunar Excursion Module Ha! Ha! But I didn’t know that one was used to cut the umbilicals between the CM & SM. Fascinating! I always wondered where the interconnects were between the CM & SM. Thanks to your explanation, I now know what that angled part that was on the side of the CM / SM stack was for. I can’t believe that I never knew that. Thanks for the information! Love your video’s. It’s great to hear from someone so young who knows so much about our early space program. Looking forward to your next video! Be Well!

I have been looking for years on commercial literature about the technical details and pictures of the disconnecting devices (gillouttine) which operated spacecraft separation, but I only found a defocused picture of the devices used in the ascent/descent stages separation of the LEM, but not the SCM.

It's so lucky that the tension ties were as strong as they were. Had the blast from the O2 tank not blown out the wide SM bay door, it could be have blown the CM off the end and only the umbilical would keep it connected, flopping over on it's side.

@HailAnts 5 жыл бұрын

It really wasn’t much of a ‘blast’ when the Apollo 13 O2 tank ruptured. There was actually very little combustion blast, it was all just the O2 tank’s high pressure releasing which caused the damage. The damage was severe for a delicate spacecraft but there wasn’t any major structural damage, it was the loss of all the Oxygen and damage to the various systems that was so severe...

Amy, I have a question: How did the tunnel between the CM and the LEM work. Join - pressurize - vent - separate - join - pressurize - vent - separate again... I'd like to see a demonstration and hear your explanation. Thanks.

@MasterChief-sl9ro 4 жыл бұрын

Actually that part was very complex. As the tension arms housed in the CM nose. Had too not only grab the Lem. But then lock the two. Then detach and move out of the way. To allow the hatch cover to open and allow them to move between both the LEM and CM. The pressure was regulated. When the two halves connected. But the volume of space between the two were very small. You got more room. In the front seat of a car..As I once got to sit in a CM.. An old mini van has more more space in the back. It was Small.....The LEM had less space..

Great video. Did you also know that unfortunately there was a major trajectory glitch on separation of cm and sm on apollo 11 on re-entry. It was supposed to skip off the atmosphere for another orbit, keeping it a safe distance away from cm re-entry. Due to an error in thruster firing the sm burned up and broke up on the same trajectory as the cm module risking damage to the CM and the lives of the astronauts. This error in thruster firing was later remedied on future missions.

I should mention that the tension ties (binding the two) were separated by pyrotechnic bolts, not guillotine as mentioned in this video. The guillotine system was used solely to cleave the umbilical.
