The two astronauts left the surface of the moon and ascended to meet the third astronaut

The time has come for these two astronauts to leave the surface of the moon after they have finished their planned work. They leave the surface of the moon to meet astronaut Collins as he orbits the command vehicle around the moon, waiting for them to ascend to it.
Here the clever technique returns and reveals one of its faces.

The lunar module has two halves, an upper half that contains the two astronauts after they entered it, and a lower half that shows the four legs visible to the viewer in the picture. This lower half is the one that contained the landing rocket, with which the entire vehicle was able to reduce its speed and land on the moon smoothly.

The ascent begins with the two astronauts launching a rocket from the upper half of the vehicle, which they are in, and its flaming breath comes out powerfully as a propellant, separating what is between it and the lower half, which will remain on the surface of the moon forever after that. They used it as a launching pad.

The lunar module (its upper half) ascends with its legs to an oval orbit around the moon, then with another rocket boost to a circular orbit around the moon.

After calculations, and after communications, involving the two vehicles and the surveillance men on the ground, one of the most difficult and dangerous operations takes place, which is the docking of the two vehicles. By docking, the two astronauts move from the lunar module to the command module, the mother module, with astronaut Collins in it.
Then the lunar module will have performed everything it intended. Then the astronauts separate it from the mother ship, so it separates and continues to orbit around the moon.

At that time, nothing remained of the spaceship except the mother vehicle, the command vehicle, and the service module that remained attached to it throughout the journey without leaving it.

When the time comes to return from the moon to Earth, we must prepare for it with extreme care, just like what we observed when launching a spaceship from Earth to the moon.

(In an attempt to dock the two vehicles, which is one of the most difficult operations, the astronauts each remained in their vehicle, working on it for 4 hours)

(The two vehicles finally docked, as you can see in the picture, and the two astronauts moved from the lunar module to the command vehicle through the tunnel, to their companion in the command vehicle. Then they separated the lunar module from their vehicle, and they no longer needed it, so it began to orbit around the moon until God willing.)

(There was nothing left of the ship, after what it was, except the command vehicle and with it the service module. So they launched the service missile to push them on their way to Earth, their way back, which is an extremely precise and dangerous operation. It requires specifying a place and setting a time, like what they needed when launching from Earth, it is the process of ridding them of the moon's gravity)

(And they set off for Earth, and almost entered the “air corridor” that they had drawn for them. There is great danger in leaving it. The service unit provides a final service in guidance. When they finished needing it, they separated it, with missiles igniting in it, as you can see in the picture.)

The spacecraft is now moving in its orbit around the moon at a speed of 5,800 kilometers per hour. But it needs to raise its speed to 8,850 kilometers per hour in order to escape from the moon, that is, to overcome its gravity, so this is the escape speed.

The astronauts reach it by igniting a rocket engine in the service module located at the back of it, and its breath comes out of that funnel-shaped nozzle, and they ignite it at the specified place and at the calculated time, and then the vehicle takes off (still carrying its service module behind it) to begin its journey to Earth, and the Earth is on After 384,000 kilometers.

The Moon's attraction to the vehicle decreases as it moves away from it, but the Earth's attraction to it increases, and it does not approach the Earth until it reaches a speed similar to that with which it escaped from the Earth. It's 39,260 kilometers per hour.

The vehicle reaches about 112 kilometers above the surface of the Earth, and then it begins to sense the Earth’s atmosphere.
Very lightly.
It started entering the airway.

Here is a great danger. This is the angle at which this layer of air enters. If it enters the air layer at a steep angle that is almost vertical, it will become hot due to its contact with it, and its heat shield will not be of use to protect it, so it will burn. If it enters the air layer at a slight slope, it may slide and exit the air into space again.

The vehicle begins to enter the air layer after
Accounting and management. If it is a slight accident, the steering devices intervene to place it at the correct angle.

Then the service unit is of no use. Then it separates from the vehicle, and eventually falls to the ground.

Only 5,500 kilograms remain of the mighty ship, which is the weight of the command vehicle, which contains the three astronauts.

The vehicle moves on its air path, after turning it upside down, using its engines (which are being used for the first time), so that it moves through the air with its broad base first, not its pointed head, as it is immune to heat.

However, the temperature of the vehicle upon its first contact with the air reaches about 2760 degrees Celsius. It's a ball of fire. But the astronauts inside are safe thanks to the heat-insulating materials in the vehicle's walls.

However, air friction slows down the vehicle's speed
When it descends a lot, when it reaches a height of 7,300 meters above the surface of the earth, its upper shield, which protects it from the heat, is removed from the vehicle, and two parachutes rise from it automatically, opening to carry it. When it descends to a height of 3,000 meters from the surface of the earth, its large parachutes automatically open, increasing its load.

- In the Pacific Ocean

Finally, the vehicle touched the surface of the water in the Pacific Ocean, where many men waited for it to pull them out of the water. In a helicopter first, then to a warship. The President of the United States greeted them there, but through glass. They were entering quarantine tanks in which they were being taken to the monitoring center, in the town of Houston, until scientists and doctors were sure that they were not...
They carry microbes to the people of the Earth from the surface of the moon that people are not accustomed to, and thus speedy death afflicts them.

As for celebrations and meetings, especially meeting their families,
This will happen after the end of the quarantine period.

Pride that the United States could not hide:

Two major space powers were competing,
America and Russia. Russia was the first. The first satellite to be thrown into the sky and orbit around the Earth was Sputnik I, in October 1957. The Russians remained the first. Then the two scales began to swing until there was no end to this American victory.

(When the Apollo 11 spacecraft entered the Earth’s atmosphere, over the Pacific Ocean, and was returning on July 24, 1969, carrying the three astronauts, the spacecraft became hot due to its speed in the air, causing parts of the spacecraft’s surface to fly off. The attached picture shows you some of these parts, and I photographed them. An airplane flew from the ground to an altitude of 10,000 metres.

(Washing with disinfectants: When the astronauts landed in the Pacific Ocean next to Hawaii on July 24, 1969, the specialized officer went up to them to wash them well with disinfectants. After that, these men did not wear special biological clothing, then they left the vehicle, and kept these clothes until they entered a closed truck-like closet. On board a United States Navy ship called the Hornet, in order to return them to the United States. Then they were transferred while they were in this closet to the lunar laboratory in the state of Texas in the United States, and there the precautionary quarantine continued for them.)

(The three astronauts, Armstrong, Collins, and Aldrin, in the quarantine room, on the warship Hornet in the Pacific Ocean. They had just returned from their trip to the moon. They remained in the quarantine room for examination afterward.)
