"Since we're here, let's go and have a look, and we also have to choose a site to see which place is suitable for setting up an experimental base."

As soon as he saw the eyes of these five people, Zhang Binhui understood their thoughts, and everyone suddenly became excited.

When his right foot stepped on the moon and watched the fine dust slowly disappear into his upper, why not abandon Liao:

"This is my first step personally, and it is a big step for all mankind, the four of us are here to play mahjong! It will definitely go down in history. ”

The moon is very quiet, there is no air, naturally there is not a trace of breeze, a little force under the feet, the body naturally floats out of the old high, and then slowly falls towards the surface.

Diagonally upward, a huge blue planet hangs there, which is the land of mankind - the earth, which looks so pure from here.

The group did not speak, and everyone moved forward quietly. Zhang Binhui released a huge enchantment to wrap around them, which could ensure the safety of the lives of these earthlings without affecting their texture to the moon, and everyone felt quite novel.

The area of the Sea of Tranquility is quite large, and it is actually a huge crater, and the basin inside is formed by the impact of meteorites.

Because of the lack of atmosphere, the moon is often hit by meteorites, and over time, the quiet sea is full of dust, so that a huge flat land is formed in this ring mountain.

The nine people walked more than ten kilometers, and a track mark began to appear under their feet, and Ling Doudou was suddenly very surprised:

"Huh? Is this what you call a legacy of the U.S. landing? ”

A strange smile appeared on Ma Tianyuan's face, and he shook his finger: "I'm afraid that it may not be, this moon is not only for Americans to come now." ”

After advancing nearly ten kilometers again, a lunar rover appeared in front of everyone, and Zhang Binhui suddenly realized: "Yutu, haha, I understand." ”

As he said, the Yutu, the lunar landing rover launched by China in 2013, is still working normally, just in front of nine people.

At 1:30 a.m. on December 2, 2013, China successfully launched the Chang'e-3 probe, consisting of a lander and a Yutu lunar rover, into orbit at the Xichang Satellite Launch Center.

At 4:35 a.m. on December 15, 2013, the Chang'e-3 lander separated from the rover, and the Yutu rover successfully sailed to the surface of the moon.

At 23:45 on December 15, 2013, the Yutu revolved around Chang'e-3 and sent back the photos.

In the early morning of January 25, 2014, the Chang'e-3 lunar rover went into hibernation on a moonlit night for the second time. However, before hibernation, due to the influence of the complex lunar environment, the mechanism control of the lunar rover was abnormal.

On February 10, 2014, the first Yutu woke up failed.

On the night of February 12, 2014, the Yutu lunar rover had fully woken up and was in good condition, and it began scientific exploration of the moon.

In the early morning of February 23, 2014, the Chang'e-3 lander went into hibernation on a moonlit night again. Previously, the "Jade Rabbit" lunar rover went to "sleep" in the afternoon of February 22, 2014.

In April 2014, the Yutu reached the end of its design life, but it was still able to wake up with a glitch in July 2014 and released its first panoramic image of the moon landing area in September.

On September 6, 2014, the "Yutu" lunar rover entered its tenth month of daylight work, and so far, it has been in service for 7 months.

Ma Tianyuan skillfully opened the energy compartment of the Jade Rabbit, then took out a battery from his backpack and helped the Jade Rabbit install it. The first lunar rover of the Chinese again made the sound of self-inspection.

"It's amazing, the Jade Rabbit can still be used!"

He Qiliao praised continuously on the side, and his hand caressed the Jade Rabbit with affection.

Here, Ma Tianyuan adjusted the lens of the overhead camera of the Jade Rabbit, and then called everyone over:

"Come on, come on, everyone line up, let's take a photo together and say hello to the Earth Control Room."

Earth, control room, the originally quiet environment suddenly boiled. Sha Yiqiang slapped the table and wept:

"relationships! Every day he says that he wants to break the barrier of human affection, and in the end, this moon landing operation is not all related households? Grandma's, I should have had a share too! ”

In front of the Jade Rabbit, after everyone showed their faces and took a group photo, Ma Tianyuan told the special mission of the Jade Rabbit:

"The landing of the Americans, to be honest, we really don't believe it. Do you think Russia is suspicious? Our scientists are not vegetarians either.

Why did the Jade Rabbit drive to the Moon Shadow District? We just want to see Jinghai and see if there is an American landing shelf here?

This study is critical to our national policy, and we must clearly assess the level of science and technology in the United States. ”

Speaking of which, Ma Tianyuan was proud:

"The Jade Rabbit is definitely the highest technology embodiment in China, the Jade Rabbit has the ability to climb 20 degrees of slopes, 20 centimeters of obstacles, and can withstand a temperature difference of 330 degrees Celsius.

The Moon's gravity is about one-sixth that of the Earth, and the surface soil is very soft and uneven, with rocks, craters, and steep slopes.

In this environment, the lunar rover can neither slip nor overturn. In order to overcome these difficulties, the Jade Rabbit has a special design.

Not only that, but the Jade Rabbit is also equipped with panoramic cameras and navigation cameras, a total of four. By "seeing" its surroundings with a camera, Yutu is able to perceive and identify obstacles on the lunar surface, and then plan its path.

When encountering slopes of more than 20 degrees, rocks higher than 20 centimeters, or impact craters with a diameter of more than 2 meters, it can judge autonomously and avoid them safely.

The rover is risky to 'walk' on the lunar surface, and the fine particles of lunar soil will be raised in large quantities, forming lunar dust, which is difficult to remove once attached.

Lunar dust may cause many failures of the lunar rover, including mechanical structure jamming, failure of sealing mechanism, loss of optical system sensitivity, etc., but our Yutu is completely able to overcome it.

Due to the very large temperature difference between day and night on the Moon, the temperature can reach as high as 150 degrees Celsius during the day and as low as minus 180 degrees Celsius at night.

In order to adapt to this extreme environment, the "Yutu" lunar rover can withstand a temperature difference of 300 degrees Celsius by using a heat conduction fluid circuit, thermal insulation components, heat dissipation surface design, electric heater, and isotope heat source.

It takes more than 28 days for the Moon to orbit the Earth, and it takes 28 days for the Moon to rotate. This means that a day and night on the Moon is equivalent to 28 days on Earth.

The minimum temperature at night on the lunar surface can drop to minus 180 degrees Celsius, and electronic devices simply do not work.

One night on the moon is equivalent to 14 days on Earth, and for this reason, researchers have designed a dormant mode for the "Jade Rabbit" -- 14 days of work and 14 days of "sleep".

For so many years, we have stopped advertising the Jade Rabbit, but in fact it is still working normally, and it is going to fulfill its secret mission.

This time, the Jade Rabbit sailed to the Sea of Tranquility because its battery was completely aging and its mission was coming to an end, so we gave it one last mission:

That is, to reach the Sea of Tranquility and find the Apollo landing capsule, we have to see if the Americans are lying. ”
