I urgently need the text Footprints on the Moon .

And in the glass, in the river, in the sky, in the heart, the moon was found.

The article "Traces of the Moon" follows the order of "looking forward to the moon - looking for the moon - discussing the moon", and the meaning and function of the key words of "moon traces" should not be ignored when reading. In the text, the author uses bamboo curtains, mirrors, and cinnamon plum trees.

Wine glasses, grape leaves, porcelain vases, grandfather's shovel blades, small rivers, children's eyes, sandy beaches, and other things clearly depict the traces of Qi Yun's movement out of the moon.

At 11:39 a.m. on the 21st, the lunar module opened its hatch. At 11:51, Armstrong walked down the stairs and landed on the moon. The surface of the moon is full of tiny particles, a bit like a beach on Earth.

Immediately afterward, Aldrin also came to the surface of the moon. It's a great moment. This is a great step for humanity.

The exact time of this moment is 11:56:20 on July 21, 1969. This is a milestone in human exploration of space.

As soon as they reached the surface of the moon, Armstrong and Aldrin immediately began intense work. They have a lot to do, but the oxygen they can breathe is limited, only enough for four hours. Therefore, every minute and every second must be grasped.

They checked the landing of the lunar lander, and everything was normal; They took out shovels and collected samples of lunar soil and rocks; They took a monument from the lunar module and erected it on the moon. The monument is engraved with images of the eastern and western hemispheres of the Earth, and it is also inscribed:

In July 1969, humans on Earth, the planet of the solar system, left footprints on the moon for the first time. On behalf of all humankind, we have come here for a peaceful journey.

Aldrin then took out the television camera from the lunar module and installed it on the surface of the moon; They also installed a solar wind measuring device to detect cosmic rays; Lasers have also been installed to accurately determine the distance between the Moon and the Earth; A seismometer to measure moonquakes was also installed. They took out the American Stars and Stripes and planted it on the moon with a solemn expression. When this was done, they breathed a sigh of relief and had the first call between the moon and the earth with Nixon.

**Warmly congratulate them on their successful moon landing.
