On July 20, 1969, humans landed on the moon.

At 9:32 a.m. on July 16, 1969, the Apollo 11 spacecraft, along with its thirty-six-storey Saturn 5 rocket, launched at the 39A Comprehensive Launching Station at Kennedy's Corner. On board the spacecraft were Civil Aviation Commander Neil-Armstrong and two Air Force Officers Little Edwin- "bubbling" Colonel Aldrin and Colonel Michael-Colince. Saturn's Third Level sent them into an orbit one hundred and eighty-eight miles high. After inspecting all the operating systems for two and a half hours, they re-launched the Third Level rocket, which allowed them to reach a speed of twenty-four thousand four hundred and fifty miles per hour, leaving the Earth's atmosphere

At fifty thousand miles from Earth, Collins manipulated the command cabin called ¡°Columbia¡± to make it face-to-face with the fragile moon landing cabin known as ¡°Eagle¡± or L-M, and the third level of Saturn was abandoned. The next day of the voyage, on Thursday, they started the ¡°Columbia¡± engine, allowing them to enter an orbit within sixty-nine miles from the back of the moon on Saturday. On the afternoon of Friday at the Kennedy Corner, Armstrong and Aldrin crossed the pipeline between two cargo vehicles, entered the moon landing cabin ¡°Eagle¡±, and the day of dawn, the astronauts entered the moon¡¯s gravity field. At this time, they were less than forty-four thousand miles away from the moon, and increas

On Saturday afternoon, they reduced their speed to three thousand seven hundred and thirty-six miles per hour and entered the orbit of the moon. The controller (they were connected by the radio telegraphs of the National Space Station in Houston to the Space Shuttle Center) awakened them at seven o¡¯clock and two minutes on Sunday, July 20, as the day was scheduled for landing on the moon. In the Eagle cabin, Armstrong and Aldrin stretched out the four unpleasant legs for the moon landing. The controller told them: ¡°You can completely get out of the boat.¡±

They entered a low orbit nine and eight miles from the surface of the moon and flew over a terrible moon wilderness filled with mountains and volcanoes. At this time, a computer in Houston began to flash on their dashboard and issued an alert to them. Now they were so close to the destination that they could not turn back, so they flew forward according to the instructions of a young commander in Houston, with Armstrong holding the manipulator, "bubbling" Odellin continually loudly reading the speed and altitude shown on the instrument. They were in trouble at the last moment of the drop, but this extension of the plan meant that they would fall into the vast, inaccessible western firewall (because they were four miles west of their goal, so called) and that "the eagle" had been

He said, ¡°Houston, here is the Pacific Sea base, the Eagle¡¯s capsule has landed.¡±This was Sunday, July 20, 1969, when the eastern sunlight saved time at 4 p.m.

After checking the instruments for three hours, the two astronauts asked Houston if they could spare the scheduled four-hour rest time and just come down. Houston replied, ¡°We support your action.¡± ¡°They wore a $300,000 space suit and lowered the pressure inside the lunar cabin. Then, Armstrong turned out and started slowing down from the level nine ladder. On the second ladder he pulled a rope and opened the camera¡¯s lens and let fifty million people see him cautiously descend to the deserted moon performance and go up. His ninth-half B boots touched the lunar surface, and he said, ¡°For a person, it was a small step, but for humans, it was a huge leap.¡± It was at 1056am and 20 seconds afternoon. He dragged his feet

Armstrong put some of it in the pocket of his space suit. Then, nine minutes after he was down the cabin, Aldrin came to him and said, "Well, beautiful, magnificent scenery." Armstrong put a sign in the ground and put the television camera on it. It looked like the spider's " Eagle" cabin was sixty feet away from the camera, and was in the center of the television image, and it was the eternal night of outer space behind him. The gravity here was one-sixth of G, only sixteen-sixth of the earth's gravity. TV viewers saw the two people jump like a lamb and heard Aldrin say, "When I lost balance, I found it very natural and very easy to restore balance." He raised a three-foot-five-foot-wide American

At the same time, the world is watching the moon. From Australia to Norway, from Kansas to Warsaw, people have their ears on the radio, or watching major events on TV. It is estimated that TV viewers have about 600 million people, accounting for one-fifth of the total population on the planet. Even in countries not friendly to the United States, the news of this lunar mission is by the radio with an attitude of appreciation or at least fairness.

Cairo Radio called the Apollo moon the "greatest achievement of mankind."A lawyer's secretary in London said the move was "just too stunning."The actress Gina-Lorobrigida said: "This is by no means a show in the entertainment industry."But "what I've seen on television today will be far from the best."

As planned, the first lunar trip will last less than a day. The moon landing capsule will take off from the moon tomorrow at 1:55 p.m. before the command capsule will fly back to Earth, it will be abandoned.

They gathered fifty pounds of stones for scientific research and measured the temperature outside of their space clothes: 234 degrees Fahrenheit under the sun and 279 degrees below zero. They put out a long metal cylinder to collect solar particles, set up a seismometer to record the moon¡¯s tremors, and set up a reflective mirror to deliver the results to the Earth¡¯s telescope. They returned to the Eagle¡¯s cabin in the middle of the night, and after a total of twenty-one hours and thirty-seven minutes on the moon, the engine left the moon (the controller said: ¡°You can take off the airplane.¡±

At 1:56 a.m., Collins sent Columbia to the Earth and started the engine to get the command cabin free from the moon's gravity. The journey back took sixty hours. That evening, the astronauts sent a picture of the Earth itself from 175,000 miles away on TV. Aldrin said: "Sitting here and watching the Earth grow bigger and the moon get smaller, this scenario is wonderful."Armstrong said: "Wherever you go, it's always good to go home.""On Thursday, they traveled at twenty-four hundred and sixty-two miles per hour and re-entered the Earth's atmosphere five and seventy miles above the Pacific Ocean. At the most critical moment of this phase, the shipping board was burned by four thousand degrees of heat.

The radar on the aircraft carrier ¡°Big Bear¡± has detected the landing ¡°Columbia¡± at thirteen and eight miles away, landing under three eighty-eight-foot orange and white parachutes. Then the command cabin crashed into the sea, aroused a six-foot high wave, and overturned. But through the cabin three men tried to blow the airbag and set the helicopter on the top of the head even if it restored the balance on the ¡°Big Bear¡± and guided the ship to the destination. President Nixon waved a double telescope on the bridge. The band in the cabin sang ¡°Columbia, you are a pearl on the sea,¡± throughout the United States and in many foreign cities, the church clock ringed, the long flute sounded, and the
