Information about man landing on the moon

1At 9: 32 am on July 6, 969, Apollo 1 1 and its 36-story Saturn V rocket were launched from the 39A comprehensive launch pad at Cape Kennedy. On board were neil armstrong, the civil aviation captain, and two air force officers, Colonel Edwin Aldrin Jr. and Lieutenant Colonel michaeljohn collins. Saturn's third stage sent them into an orbit 1 18 miles high. After checking all the working systems for two and a half hours, they launched the third stage rocket again, which enabled them to get a speed of 24,245 miles per hour, leave the earth's atmosphere and go to the moon 250,000 miles away.

50,000 miles away from the earth, Collins operated a command module called Columbia, facing a fragile lunar module called Eagle or L-M for short. As soon as Colombia hooked up with the eagle, Saturn III was abandoned. On Thursday, the second day of the voyage, they started the engine of Columbia, which enabled them to enter the orbit 69 miles from the back of the moon on Saturday. On Friday afternoon, Cape Kennedy time, Armstrong and Aldrin climbed the pipeline between the two aircrafts and entered the lunar module Eagle. At dusk that day, astronauts entered the lunar gravity field. At this time, they were less than 44 thousand miles away from the moon, and the speed was getting faster and faster.

On Saturday afternoon, they slowed down to 3736 miles per hour and entered the orbit around the moon. The air traffic control station (whose wireless telegraph contacted NASA's Spacecraft Loading Center in Houston) woke them up at 7: 02 a.m. on Sunday, July 20th, because it was the scheduled day to land on the moon. In the Eagle module, Armstrong and Aldrin stretched out four ugly legs for the lunar module landing. The air traffic control station told them, "You can leave the dock completely." So the lunar module was separated from Columbia, and Armstrong said, "The eagle has grown wings!" " At 3: 08 pm, he started the engine of the spaceship, so they flew to the sea of tranquility on the moon.

They entered a low orbit 9.8 miles from the surface of the moon and flew in the terrible lunar wilderness full of mountains and craters. At this time, a computer in Houston started flashing on their dashboard to remind them. Now they are so close to their destination that they can't turn back, so they fly forward according to the instructions of a young commander in Houston. Armstrong holds the manipulator, and the buzzing Odelin keeps reading the sailing speed and altitude displayed on the instrument. They had some trouble at the last minute of the descent. When Armstrong found that they were going to land in the vast inaccessible western crater (so called because they were 4 miles west of the target), the distance between the Eagle module and the moon was less than 500 feet. He flew outside the crater, but the unplanned extension of the journey meant that his fuel was about to run out; He must make a decision at once, either turning over or risking the plane crash. Just then, two white lights appeared on the dashboard in front of him, showing the words touch the moon. The eagle has landed.

He said, "Houston, this is Jinghai base, and the Eagle module has landed." It's Sunday, July 20th, 1969, 4 pm Eastern Daylight Time. After checking the instruments for three hours, two astronauts asked Houston if they could get off the plane now if there was no scheduled four-hour rest. Houston replied, "We support your action." They put on $300,000 worth of spacesuits, which reduced the pressure on the lunar module. Then Armstrong turned his back outward and began to descend slowly from the ninth ladder. In the second step, he pulled a rope and turned on the lens of the TV camera, so that 500 million people could see him carefully landing on the desolate moon.

His nine and a half B boots touched the surface of the moon. He said, "This is one small step for man, but one giant step for mankind." It's afternoon 10, 56 minutes and 20 seconds. He dragged around on the ground. He said: "The surface of the moon is thin and pink, covering my soles and uppers layer by layer like charcoal powder. I stepped less than an inch deep, maybe only an eighth of an inch, but I could see my footprints on the sandy ground. "

Armstrong put some fine powder into the trouser pocket of his spacesuit. Then, 0/9 minutes after getting off the boat, Aldrin came up to him and said, "Beautiful, beautiful, magnificent and desolate scenery." Armstrong drove a stake into the soil and installed a TV camera on it. The eagle cabin, which looks like a spider, is 60 feet away from the camera and is located in the center of the TV image. Behind it is the eternal night in outer space. The gravity here is one-sixth of a g, which is only 16.6% of the gravity on the earth. Television viewers saw the two men jumping around like antelopes and heard Aldrin say, "When I was about to lose my balance, I found it very natural and easy to regain my balance." He raised an American flag three feet long and five feet wide and tied it to the flagpole with wire; Aldrin saluted it. They also stored a container containing telegrams from leaders of 76 countries and a stainless steel plaque that read: "People from the earth set foot on the moon for the first time in July 1969. We came here peacefully on behalf of all mankind. "

At the same time, the whole world is watching the moon. From Australia to Norway, from Kansas to Warsaw, people put their ears to the radio or watch important events on TV. It is estimated that there are about 600 million TV viewers, accounting for 1/5 of the total population of the earth. Even in countries unfriendly to the United States, radio stations reported the news of this mission to the moon with appreciation or at least fairness.
