Record a trip to the moon in the United States.
Here is an excerpt from Chapter 12. )
The footprints on the moon always have the moon. With it, there is an unwritten history.
Perhaps the story of creation itself.
Always the moon, staring at the sky of everyone.
There is nothing that captures human eyes and thoughts so much.
She stood on the horizon as always, shrinking at her peak.
On a sultry night, when the sun rises from the ocean, she burns like orange.
On a blue summer day, her ghostly New Moon haunts the sky of the day.
On a clear desert night she was a pristine silver ball, small and lonely.
She and the Sun jointly command the tides of the Earth's oceans.
However, her simple cycle keeps time through the metabolism of mice and tide crabs.
The Sun gives people day and night.
The moon gave him weeks and months.
The clock of the lunar calendar is ticking.
What is the reason for Grunion running?
When is the growth of human fertility?
What makes rock crabs go ashore for food?
Only what can cover the sun? The moon. The moon. The moon. July, 1969.
The moon is no longer a complete mystery.
As Neil Armstrong said, Apollo 11 will not be a flight to the unknown world.
The moon was measured, compared, and viewed.
She is more like an asteroid than the moon, the largest of the 32 satellites of the nine planets in the solar system.
She measured 2,160 miles in diameter and 6,790 miles around her waist.
She is less dense than the Earth.
Even though she is
Fourth, her quality is only 100 of the Earth.
She has only one gravity.
As powerful as the Earth's gravity. A 150-
The Earth weighs only 25 pounds on the moon.
She's an extreme woman.
Her day is 14 Earth. days long.
Under the emptiness of the beam and shadow of Sun 1, her temperature ranges from minus 243 degrees to minus 279 degrees.
There are still bigger problems with all the small physical facts.
How did all this begin?
There are three main theories: when the Earth rotates faster, the moon breaks out from the Earth and is thrown down by centrifugal force;
Two objects are formed at the same time, condensed from the original gas created;
The moon is a wandering planet captured by the Earth's gravity. Daughter? Sister? Captive wife?
These questions were still unanswered when Apollo 11 was ready to fly.
Part of the reason they went.
So in July 1969, as always, the moon, strange foreign bodies in the Earth's sky.
The world sees her as three, contrary to her bleak new image of craters and mountains? _?
Armstrong, Aldrin and Collins
On the eve of history, maybe men can't sleep well, or they shouldn't sleep well.
Their break was delayed by an hour before going to bed on Saturday nightand-a-
Half was found because of a nasty communication problem.
They were woken up at 7: 02 in the morning. m.
Armstrong on Sunday-and-a-
Collins slept for half an hour, Aldrin for six hours, and Aldrin for five hours.
This is the shortest rest time for the flight.
It took them half an hour to have breakfast.
The mission control center sent an update to their family and Morning News.
Aldrin was told that his son and an uncle visited the space center.
Then it's time to start work.
Aldrin was the first Eagle to enter at 9: 20. m.
Nearly an hour later, Armstrong slipped out of the tunnel and joined his team.
They have been Eagles since then.
Collins is from Colombia. At 12: 32 p. m.
They pressed a button that extended the Eagle's Landing leg.
Thus, Colombia and the Eagles, which are still connected, arrived at this incredible time and place, invisible and invisible to their radio connection to Earth in orbit 13 of the moon.
About 100 hours have passed since they left their home.
Now, 240,000 miles from it, they are about to devote themselves to history.
Behind the Moon, Collins pressed a simple button.
Click on the latch to open.
Prince gave the eagle a gentle push.
They are waiting for news on Earth.
The radio signal finally arrived.
It was Armstrong's voice crackled in static electricity.
"The Eagle has wings," he said.
Now, they flew together briefly, and Collins looked at the strange boat Columbia had gone so far.
"Eagle, it looks like you have a very nice flying machine there," he said, "despite the fact that you are upside down.
The Eagle replied, "someone has come down . ".
Less than half an hour later, Collins fired a rocket into Colombia and rushed over two miles ahead, giving the eagle room to fly.
"See you later," he said.
The eagle is his own.
They pass again from behind the moon, to the point in orbit, where significant changes have taken place, again out of sight and radio contact of the Earth.
Armstrong and Aldrin tilt their boats to make the Rockets face the direction of the flight.
When they came out from behind the shadow of the moon, the Earth heard Armstrong say: "The burn was done on time.
Collins confirmed, "Look, baby, everything's going well.
The decline in the surface of the moon has begun.
Eagle flies through a long circular arc, riding the tail of a rocket fire like a brake, moving at a speed of 3,700 miles per hour.
According to the mission control center, the current altitude is about 46,000 feet.
"Everything is fine here.
"Eagle:" The downward range of our position check shows us a bit off.
"Mission Control:" You will continue to lose momentum.
Looks good.
Everything looks good here.
"In addition to the reassuring voice of cap com, the task control department was completely silent --
Just like the reports from the engineering and flight dynamics channel.
"Two minutes and 20 seconds, everything looks good," the mission control center reported . ".
"I'm a little volatile," Eagle said . ".
"It looks good," said Task control.
"Let's look a little long," insisted the eagle . ".
"You will continue to drive down," the mission control center insisted . ".
"You look good.
"Take the earth out of our front window," Eagle reports . ".
The guide computer on board showed some changes.
"You look great, Eagle, you look great," the mission controller said with confidence . ".
"You land.
"Roger, get it," said the eagle.
"To land, 3,000 feet. . . 2,000 feet . . .
Okay, it looks like it's being held.
Armstrong's voice was clear, as brisk as a stock market report.
But his heart rate is 40 jumps higher than normal.
Now, one thing happened, 156 beats a minute, but his voice never betrayed it.
He saw the landing sites scattered beneath the boulders.
He crossed the automatic landing pole.
Grab the rocket control device in your right hand and skip the scattered grounds to find a clear spot: "540 feet. . .
400 feet, good health. . . 200 feet . . . 100 feet . . .
75 feet. It looks good. Drift to the right a little. . .
"The Rocket raised 40 feet waves of dust around the spacecraft. "Okay . . .
The engine stopped.
"Houston," Armstrong said tentatively . "A long pause.
Then: "This is a quiet base.
The Eagle landed.
"Roger, quiet," sighed the mission control center.
"We copy you on the ground.
You have a bunch of people going blue.
We're breathing again.
"The time is 4: 18 p. m. m.
Cape Kennedy time on Sunday, July 20, 1969.
Man landed on the moon.
In Mission Control, nearly 100 space agency experts crowded into the viewing room to look past the shoulders of flight controllers sitting behind the console.
These include John Glenn from Apollo 10, Tom Stafford and Gene Cernan, Jim McDevitt from Apollo 7 and Walter Cunningham.
"Armstrong doesn't know what's going on Earth, and it could be a good thing," Cunningham said . ".
"Neil is the coolest person in communications.
"Now is not the time to calm down.
All the flights and all the people led to this moment.
Eugene Canz, the flight director, was pleased to shoot his console.
After him, everyone applauded and cheered.
Kranz suddenly realized that discipline had collapsed.
"Everyone is fine," he shouted.
Settle in.
"The day is not over yet.
There are better moments in the store.
At the White House, President Nixon watched TV coverage with Frank Borman.
The last 22 seconds were more like half an hour, he said.
When he held his breath, he congratulated the astronauts.
"This is one of the greatest moments of our time," he said.
Buzz Aldrin explained the last-minute difficulty: "It seems to be a very long final phase.
The car aimed at bringing us directly into football.
Site-sized crater
There are a large number of large stones and rocks around, about one or two volcanoes in diameter.
It requires us to do so. . .
Fly over the Rock area manually and find a fairly good area.
Armstrong pointed out: "You may be interested to know that I don't think we have noticed any difficulties at all in adapting to one --sixth gravity.
It seems natural to move in this environment.
He said that the front is a relatively flat plain with a considerable number of five ring-shaped mountains --to-50-
Variety of feet, and some ridges, small, 20-30 feet high. I would guess.
And thousands of smalland two-
The foot crater around the area.
We saw a few hundred feet of corner rock in front of us, about 2 feet in size, with horns on the edges.
There is a hill on the ground track in front of us.
It's hard to estimate, but it could be half a mile or a mile.
"Please note," said the mission control center, "there are many smiling faces here and around the world.
"There are two here," Armstrong replied . ".
"Don't forget the one here," Collins shouted on his lonely patrol.
Then, he added: "You did a very good job at the quiet base.
"Just keep that track base for us," Armstrong replied . ".
The first task is to check the spacecraft.
Armstrong and Aldrin have concentrated on attractions that have never been seen before.
"Coming out of the hatch, tm looks at the Earth, big, round and beautiful," Aldrin said . ".
"The Sun plays games with the colors of the surrounding moon rocks.
"You can find almost all kinds of rocks," Aldrin looked out of the window and said . ".
"Depending on the way you look at it, the color will be different.
It doesn't look like a normal color at all.
"The Eagle stands about four miles from the planned landing site.
It also has a slight tilt but is not enough to put off at risk.
"Those who say we can't tell exactly where we are the winners today," Armstrong said . ".
"In the drop section where we usually pick the landing location, we're a little busy worrying about things like program alerts.
"Slowly, they release pressure from the spacecraft, release oxygen, and vacuum into it. At 10:40 p. m.
According to Armstrong, "the hatch is about to open.
"Then, following Aldrin's instructions, he began to return to the porch of the ship, careful that his suit was not caught or stuck on the narrow opening.
Slow progress. His 185-
The pound suit weighs only about 30 pounds under the moon's gravity, because it has a large volume, so it becomes a hindrance.
All of a sudden, he stood on the porch of the Eagle and began the tentative steps along the nine steps of the ladder.
On the way, he pulled a lanyard and put a Equipment shelf and a TV camera.
Now, on screens all over the world, you can see the naked shadows, there, rocking, looking, a boot, Armstrong's boots.
The whole person showed up a little bit.
Now, from the last ring to the flying saucerlike footpad.
Then he was careful, not sure what was underneath, and he stepped on his left foot, a 1/2-yard foot, with a clumsy, clumsy pace.
He pressed the surface of the Moon at 10: 56. m.
His first sentence is, "It's a small step for a person and a big step for human beings.
"Before Buzz Aldrin stepped down the ladder along the same backward route to join him, he walked alone on the moon's alien land for 20 minutes.
Aldrin looked around and his first sentence was: "beautiful, beautiful, beautiful.
Spectacular desolation.
At first, Armstrong walked carefully, almost in the shuffle, and then confidence grew.
He found that after four times, the Eagle's foot pads only pushed 2 inch into the lunar soil. foot drop.
He guessed that he had only pressed one inch on his own foot.
But he could see his footprints on the dusty ground. At 11:42 p. m.
Armstrong and Aldrin spread the star-spangled flag, erected the pole that stretches along the top, keeping the flag tight in an air-free, windless Moon atmosphere.
Aldrin stood up and saluted.
Armstrong stood up.
Just a few minutes ago, the spaceship commander from Ohio stood on the side of the Eagle and read the plaque posted there in a steady voice to the listening world.
"In July 1969, humans set foot on the moon for the first time," read Amsterdam . ".
"We are here for the peace of all mankind.
"In the Oval Room of the White House, President Nixon's voice rang through telephone and radio in an empty 240,000-mile stretch.
"I just can't tell you how proud we all are of everything you do for every American," he said . ".
"This must be the most proud day of our lives.
For people all over the world, I am sure that they also recognize with the Americans what a great feat it is.
Because of everything you do, heaven has become a part of the human world.
When you talk to us in a peaceful ocean, it inspires us to redouble our efforts to bring peace and tranquility to the Earth.
In the whole history of mankind, a priceless moment, all the people on Earth are truly one.
They are proud of what you have done and we pray that you return to Earth safely.
Neil Armstrong said, "We are very honored to be here, not only for the United States, but also for the people of peace countries, who are interested, curious and looking forward to the future.
"In the next bold few minutes, Aldrin crossed the moon panorama in front of the eyes of the TV camera now set up to measure Eagles and Eagles.
Both collected samples of soil and rock, and a metal foil shadow was set up to capture the subatomic particles that the solar wind of the sun blew through space.
They also set up a seismic instrument to measure the vibration of the moon's crust and a mirror.
Like a device that reflects the laser back to Earth and helps measure the distance to the moon, the accuracy is 6 inch.
They packed everything that had to be in a big white suitcase, like boxes, rocks, core samples, dirty bags, foil facing solar energy.
The earthquake, the Mirror, the flag are still behind. At 1:11 a. m.
On Monday, July 21, 1969, they closed the eagle hatch behind them.
In six hours, Armstrong and Aldrin sit again with Collins in relatively comfortable Colombia.
Docking is a bit of a problem, but nothing serious.
The astronauts actually arrived at the mother ship about two hours in advance.
The eagle is abandoned and will remain in space as long as its lunar orbit continues.
It will eventually hit the surface of the moon.
Just 11 hours after they left the moon, they shot the Columbia engine twice. and-a-
Half a minute later, a bead was drawn on the Earth.
Armstrong and Aldrin were tired and the mission control center ordered them to sleep for a while.
If not very soon, the trip back to Earth is quiet and quiet.
Almost no problem, Colombia flashed in the sky of the Earth, and splashed at 12: 50 in the warm waters of the Pacific Ocean. m.
On Thursday, July 24, it took off 8 days, 3 hours and 18 minutes from Cape Kennedy, Florida.
It landed just nine miles from the eyes of the aircraft carrier bumblebee and President Nixon, and even if he could not shake hands with the astronauts, he would greet them with his hand.
They immediately entered the complex isolation system where they would stay until August 11 to protect the Earth from any possible contamination of bacteria on the moon.
The president, in an isolated van surrounded by a naval guard of honor, faces the three men through glass windows.
When the Navy band raised the star-spangled flag, everyone stood up.
The president then announced, "This is the greatest week in world history since the founding of the People's Republic.
"Because of everything you do," he said, "the world has never been so closely integrated.
He invited them to a state dinner in Los Angeles in August 13. "Will you come? " he asked.
"We will do whatever you say, sir.
Neil Armstrong replied.
The three faces in the window were fresh with a bright smile.
Collins had a beard on the plane.
After the astronauts took their only Open pace on the aircraft carrier, there was an ironic moment, a 10-
Walk to the van from the helicopter that picked them up.
Just after the door of the quarantine truck closed, a scientist in a short time
Long-sleeved yellow shirt quickly sprayed the passage with disinfectant.
This is the most strange hero welcome ever.
During those difficult days after the return of Apollo 11, three Earthlings were isolated.
First, a photo technician touched a pack of lunar film with black lunar dust on his hand.
Then, when the gloves split, two hands with gloves were contaminated with the man handling the moon rock in a small vacuum chamber.
Astronauts stay healthy, perhaps boring, but healthy in isolation.
The experiments they left behind and the rocks they brought have begun to tell the history of the moon.
An earthquake or meteor hits the moon.
A scientist said the moon under study was "like Aladdin's Lamp ".
Rub them with the right tools and they will tell you the secrets of the universe.
"Space exploration is also a magic lamp for Aladdin.
It once again reveals that the greatest behavior of man often comes from his most strange motives.
The cold war between nations has given mankind a new planet to walk on.
