This is the insides of the service module. I don't see much in the line of fuel.
They don't need a lot. The SPS engine only burns for a few minutes.

Two of the four fuel tanks are sketched in outline in that drawing so you can see the helium tanks behind them. The arrow labeled FUEL STORAGE TANK points near the bottom of one, FUEL SUMP TANK points at the bottom of the other. There are two more like them on the other side.

Here's a another interior view. The two large cylinders are the SPS fuel tanks.


Quote
So, you are saying that once it leaves the moon the inertia will carry it 238,900 mi. to earth
Essentially, yes. The engine doesn't need to fire continuously to keep moving. In fact, it speeds up as it approaches closer and closer to earth. It's falling toward earth, remember?

Quote
and how do they steer this thing towards earth?
If they start out in the correct trajectory, they will arrive at the desired point. This is accomplished by burning the SPS for the correct amount of time in the correct direction at the proper place in the orbit around the Moon. Errors in the initial trajectory are adjusted by making midcourse corrections along the way - generally short burns in a calculated direction at a calculated spot.

Quote
It doesn't show any rockets to steer it by.

Yeah it does. Each RCS Quad has four small rockets (hence "quad"), and there are four of these quads [IIRC] spaced evenly around the outside of the SM that are used to orient the craft in space by firing in specific directions in combinations.

Quote
Careful design, planning, and execution. They had very good rocket scientists and aerospace engineers working on it, and a well-trained crew aboard.

But what keeps it from wobbling when it enters earth's atmosphere. It stays at the perfect angle as it is coming in
There's a whole branch of aerodynamics called "blunt body dynamics" that has the answers to this question. Apparently a body shaped like this will tend to remain oriented flat side first, but this is far from my field of expertise. You're the aerospace guy. Look it up and you tell us.

Quote
and the shield is hot enough to melt butter and then it deploys parachutes for a soft landing in the water and then it deploys a tubular life raft around the thing to keep it from sinking. Like this picture shows.
 
My question is, where do they keep this inflatable raft so it doesn't get burned up? You can see it is attached right at the part that is going to get pretty darn hot.
Presumably behind the heat shield which, IIRC, is jettisoned after the parachutes open. You're good at Google. I'm sure you can find it.

Im sorry but physics isn't simple, I know you want to be special and be the only person knowing real physics, so you create your made up simple physics. But thats no how the real world works. Again, I sorry.
That is how the real world works. The world works in simple ways. It's just made into gobbledegook so people cannot fathom just how simple it is.

The bullshit is what keeps the elites from the downtrodden. The tricksters who ask you which cup the ball is in and show you how easy it is to pick, until you pick the empty cup.
Manipulation and sleight of hand.
Stand back and take your time to decipher the bullshit then the sleight of hand and you start to see the pattern.

If you want 1+1 to equal 2 then have a reason for it to do that. If you find that 1+1 does not equal 2 according to a physics professor, then ask yourself if there's a physical end product to that calculation. If you find there is only a theory as an end product, then discard it and stick to the reality which can be physically calculated.
No, physics being complicated means you are too stupid to understand it, so you have to make up your own simple version so that you can pretend to have smarts.
The reason your life is so shit isn't because the elite, it's because your a retard.
But no, you see "the pattern" that you made up, must be smart.

Thanks; I am.

Because anyone who believes we went to teh munn in a bunch of flying trashcans designed over 50 years ago, all carried in a three thousand ton shpayze-rokkit dripping with occult symbolism, is too dumb to deserve a longer response.

You gotta be seriously brainwashed or a functional retard to fall for that baloney.

Look what the folks who did it think of you:

It was voodoo.

Yendor comments "and the shield is hot enough to melt butter", well he could have looked up a little info himself!
It would not just melt butter, it would readily melt aluminium and probably melt brass!  The heat shield gets bright red hot!
But this whole line of questioning here comes down again to the implication "I don't understand it, so it must be a fake!".  For heavens sake do a little work and get to understand this stuff.

The circle around the earth is a circular orbit, the path between the earth and moon is a section of an elliptical curve around the earth, untill near the moon, when the rocket changes it's trajectory to a elliptic orbit around the moon, which is then stabilized to a circular orbit around the moon.
Forget around the moon.

You can't. It's where they're going, remember?

Have you never heard of, 'Being  Facetious'.

In rabinoz's defense, it's hard to tell if you're being facetious or not, given many of the astonishingly wrong things you often say here. Are all the outrageously wrong things you say here in jest, only the wildly understated ones, or some of either or both?

It will get tedious asking (and reading) "are you kidding?" before replies to wacky assertions from you, so please give us some guidelines so we can assess when you're just kidding and when you're not, or something like a winky-face emoji when you're being facetious; that's what they were invented for.

Quote

Why do you guess that? rabinoz obviously knows, too (presuming you really do know how hot it gets), and I didn't see anyone claim otherwise. Calm down.

Not a bad attempt at swerving the issue but the questions are still there to be answered. If you can't do it then that's fine. If no one else can, then that's fine again because it means there's a good reason. It means the so called science behind it all, is bullshit.

The other side probably can't use Google.
I didn't think you'd even heard of it considering the questions you ask and how easily the answers are found on it.

I'd prefer any one of them to explain it to me as if I was a child and at least by doing that we can determine how it all  worked.
Why?  Every time we've explained things to you at a 'child's level', you still basically say "I still don't get it."

Every time I ask. nobody explains anything. They go into copy/paste mode. There's a good reason for that. It's because 99% of you people cannot think for yourselves.

Maybe you missed the earlier answer. Here's the "good part", in case you don't recognize it:
The TLI burn of the S-IVB put the craft in an elliptical orbit that intersects the Moon's orbit (lower left part of your diagram).  As it nears the Moon, this orbit is perturbed by the Moon's gravity
Now, you may think the word "perturbed" is worth a giggle - who knows - but it has a specific meaning that refers to orbits being affected by the presence of other objects, and has nothing to do with genitalia or sex[nb]Sorry![/nb].

At any rate, it means that the presence of the (rather substantial) mass of the Moon affects the orbit of the Apollo spacecraft substantially when it's in the vicinity of the Moon. You can't just "forget around moon". Reality doesn't work that way.

Quote
If you can't do it then that's fine. If no one else can, then that's fine again because it means there's a good reason. It means the so called science behind it all, is bullshit.
Perhaps, or, more likely, you simply don't, or refuse to, understand he answers you get. Not being able to help you understand may be inadequate explanations, or it may be your problem. There's nothing anybody by but you can do about the latter.

Nice try, though.

There's also a reason why basic logic outweighs basic bullshit. There's a reason why simplistic reasoning far outweighs nonsensical fantasy.

The only reason why many things are made so complicated to understand for people is because the populace has to be separated into classes so the slaves can be repetitive in serving the masters and are bred to DO - not to think.

Things are only difficult depending on who is explaining or showing you.
The major issue with most people is the fact that they dare not accept simplicity in understanding because they fear it makes them appear to stand out as backward when confronted with a person who has memorised the complicated  bullshit that takes them around the perimeter rather than through the clear shortcut.
That's your so called science world.

Your rocket science is exactly the same. It's not rocket science, is a term used to make out something is easy whilst rocket science is deemed scientifically complicated in it's set up.
A rocket is simple in reality but complicated when the bullshit of space gets involved.

Wow.  What utter hogwash.  The reason that many thing are made so complicated to understand is because the closer you look, the more complicated they are.  For example, in principle, starting a car's engine is very simple -  turn the key and it starts.  But what's happening when you turn the key?  Well, turning the key turns activates a whole sequence of events that need to happen in order to start the engine.  If you look deeper, each of those events requires more things to happen and so on.  Most people don't really care what happens when they turn the key so long as the engine starts.  Does that mean that they're slaves to the auto industry masters?

Same thing with floating in orbit.  The principle is fairly simple, but the closer you look, the more complexity you run into.

The concept of a rocket is simplicity in itself and one of the easiest examples of newtons 3rd and conservation of momentum you could possibly see. Space makes things very simple as the forces involved are straight forward. Orbital mechanics can be a little trickier though.

Rockets get complicated when you build them in reality due to the engineering requirements of fuel supply, guidance and materials.
Never attribute to malice that which can be explained by ignorance or stupidity.

You get a large 10,000 piece jigsaw. You see a picture on the front of the box. It looks a nice picture. It's a picture of a Porsche.
You open the box to see thousands of little jigsaw pieces.
It now looks daunting. Too many pieces to put together.

You decide to find the 4 corners and all the straight edge borders. Then you look for the most stand out colours.
Before long you have built the jigsaw from bottom up.

Do that with science and things start to look more simple and can be explained in a simple way that can re-start the logic of the most stubborn indoctrinated/ignorant mind.
