1 -The ascend part of the lander and the service modul docked at some point. The astraunauts went from one space craft into another. Wouldn´t they need a chamber in one of the crafts so the pressure would be equalized?
2- The lunar module would probably need such a chamber too, since it was unlikely that the astraunauts walked out of a cabinet with pressure straight into vacuum. I haven´t seen a chamber like that in any one of the LM pictures on the internet, can somebody explain that?
3- If as claimed the lander ended up landing miles away from where it originally was supposed to, wouldn´t that require reprogramming everything so it wouldn´t miss the CM on the way back? Did NASA know exactly where the lander had landed? Wouldn´t it take an inch for the lander to miss the orbit unless it took off at the right second and from the exact location?

1) The pressure was engineered to be the same in both craft: 5 psi of oxygen, as it was in the suits.
2) The lunar module was evacuated (air dump) before its door could be opened. It was repressurized after boarding. No air lock. LOX tankage massed less than an airlock and mass was at a premium.
3) Rendezvous only required good orbital matching (timing and aiming) not good position matching. It's vacuum, git - no air resistance. Any applied force permanently bestows velocity until another force is impressed. Given precision, accuracy was only a matter of patience and launch window for the return. Course correction as necessary was applied on the way home.

Let me tell you that I'm not an expert but I'll answer the best I can based on what I've read when it happened (I was too young) and my knowledge of physics.
1 - There was a door (I think they were two actually but it doesn't change the problem) between the modules and a valve to equalize the pressure at both sides of the door. There's no need for an extra chamber.
2 - The module was de-pressurized before opening the door. On the way back, they closed the door, pressurized the module and took off the suits.
3 - The CM and the LM entered an orbit together, separated and then the LM landed. The landing point was on the line of the orbit of the CM, no matter how much off the originally planned position. When the LM reached the orbit level, it was on the same line where the CM was circling the Moon.

1: There was a docking tunnel that was ealed by a hatch in each module. Before opening the tunnel the pressure was equalised.
2: The lunar module required no such chamber. The astronauts put on their spacesuits and pressurised them, then they simply depressurised the interior of the LM. Indeed, the LM door opened inwards, and therefore simply could not be opened while there was any internal air pressure.
3: The LM launched into an orbit, then manoeuvred in that orbit to catch the CM. Rendezvous and docking in space is not simply a case of firing off the surface to meet the orbiting craft straight away.

The space suits acted as the chamber you are looking for. They passed from lander to command module thru a tunnel, and the tunnel cannot have both doors open at the same time.
In the tunnel, air was let into the tunnel and the suits help equalize the pressure, so they could enter the command module easily.
The second part of the question or third part, is what they call a launch window...just like the windows they used on earth.

I am a little old but I was there and u are trying to say that it is not fact. With the thousands of people involved u actually think we could of kept a scam secrete. Then the second flight left a special mirror up there and we rainged on it with a laser to measure the precise distance to the moon. The laser ranging was accurate to + - 10 cm. is that closet enough for u. T sat the tracking console on most of these missions and we new exactly where they are. I have some pictures that were given to me by NASA .

1. no they just open a really small hole before they remove the hatch the connectis the pieces.
2. there was such a chamber but not on the side of the ship but on top (the same whay they connect to the ship)
3. yes it would take some reprograming but unlike the spaceships of today much of the flying was done manulay (including the docking)

To answer your real question: Yes, the USA landed on the moon. More than once, too.
