With everyone's attention, the road leading to the bottom of the crater has finally been repaired. It is said to be a road, but it is actually a temporary passage to facilitate the entry and exit of vehicles.
A road of about thirty meters was opened diagonally downward from the edge of the crater. In order to save time, the entire road was relatively narrow and could only accommodate the passage of these four vehicles.
Just such a narrow passage took these two multi-purpose engineering robots more than two hours.
So after the road was repaired, the Wangshu-2 lunar surface patrol test vehicle and engineering transport vehicle waiting above quickly descended to the bottom of the crater along the access road.
This is a large crater with a diameter of one to two hundred meters. Of course, in our opinion, this crater is already very large, but on the moon, this is already considered a small crater. Because of course it is the largest crater on the moon.
Which lunar maria can reach hundreds or thousands of kilometers in diameter, and even some slightly smaller craters can reach tens of kilometers, more than ten kilometers, or several kilometers.
And a crater like this one with a scale of 100 meters is already relatively small. Of course, there are even smaller craters, the kind of tiny craters that are tens of meters or a few meters long.
The gold meteorite core is not located in the center of the crater, but in a small crater more than ten meters in size near the center of the crater.
This crater is relatively small and shallow, and is considered a very inconspicuous one among the many small craters. But even in this inconspicuous small crater, there stands a golden meteorite star core that the whole world is paying attention to.
After all four vehicles arrived at the bottom of the crater, they quickly formed a team and started heading towards the location of the golden meteorite core.
Although there are some small craters and debris at the bottom of the crater, it was hit after all, so the terrain is relatively flat, making it easy for vehicles to pass.
So it didn't take long for the four vehicles to arrive at the location of the golden meteorite core. For the first time, everyone saw the golden meteorite core standing in the middle from the live broadcast.
However, when everyone actually saw this golden meteorite planet, they all showed disappointment. This rusty, rough-looking broken stone ball in front of them, you said it was gold, which naturally caused a stir.
Many people doubt it.
In everyone's inherent impression, this golden meteorite star core should be a shining golden metal ball, or have a texture similar to that of a walnut, which should emit a very dazzling light under the sunlight.
But the rusty stone ball in front of everyone is very small first of all. Its diameter is only about fifty or sixty centimeters to everyone's eyes. It is so small that those who don't know think it belongs to whose community it is.
The stone ball blocking the car at the door has gone to the moon.
Just when many people were talking about this rusty stone ball, everyone in the Xinyuehu Aerospace Command and Control Center looked a little excited when they saw the golden meteorite core that they had longed for again.
Even Zhou Xiangming, who was steady at work, couldn't help but look excited. Finally, they finally found it again. Thinking that they would soon be able to transport this golden meteorite core back to Earth, everyone couldn't help but look excited.
Look of joy.
Lin Wei, who had been watching the entire live broadcast with great interest, could not help but show a puzzled look at this time. She turned to Wu Hao who was sitting next to her and asked softly: "Why do I look at it like it's a living thing?"
A rusty stone ball doesn’t look like gold at all.”
Hahaha, after hearing Lin Wei's words, everyone around them laughed.
Wu Hao smiled at her and asked, "Do you know Nugget Gold?"
I know, I heard that it is now more expensive than pure gold. Lin Wei nodded blankly and said, she was not sure why Wu Hao asked this question.
Hearing Lin Wei's answer, Wu Hao smiled and replied: "The so-called nugget gold actually refers to naturally produced, impure texture, containing placer gold lumpy gold with large particle size and irregular shape. Because the shapes vary.
They are different in size and shape, and many of them resemble dog heads in size and shape, so over time, people called this type of gold dog head gold.
It is actually an ore with a very high gold content, some can reach 60 to 70%, some can reach 780%, and some can even reach more than 90%.
The gold meteorite core we are seeing now is actually a large gold nugget with a gold content of about 70%.
Of course, this is only the result of our detection on the surface. Maybe inside it, especially towards the center, its gold content may be higher.
In addition to gold, it is also rich in other metal elements, such as silver, platinum, ruthenium, rhodium, palladium and more than a dozen metal elements.
It contains some metals that are easily oxidized, so it forms such colorful colors, which is why we see it like a rusty stone ball."
Isn't there no oxygen in space? Can it still be oxidized? Lin Wei couldn't help but ask.
Wu Hao smiled and replied: "There is no oxygen in the water, so why does iron rust when put in it?"
You mean water? After Wu Hao reminded her, Lin Wei couldn't help but react and said excitedly.
Wu Hao smiled and shook his head: "There are many ways to oxidize metals. It is not necessarily air, water, or even high-temperature burning that will oxidize metals.
The surface of this gold meteorite core must have experienced slight burning, which is why it has a color similar to oxidation rust. The exact cause will have to be transported back and carefully studied and analyzed before we can know the exact result.
"
Speaking of this, Wu Hao couldn't help but smile and shook his head and said: "There may be no result, because we can understand too little about this universe."
Speaking of this, Wu Hao looked at Yu Chengwu and Zhou Xiangming who had been waiting for his order, then waved his hand and said: "Let's get started."
yes!
As the order was issued, the four vehicles began to perform their respective duties.
The first is the Wangshu-2 lunar surface patrol test vehicle. It uses the small intelligent robotic arm mounted on its vehicle to start cleaning up the debris near the core of the golden meteorite.
While cleaning, the Wangshu-2 lunar surface patrol test site will also select some rocks and debris and put them into the specimen box on its own vehicle.
Yu Chengwu on the side also explained to everyone at this time: "In this mission, we are not only transporting the golden meteorite core back, but it is also a scientific detection mission.
Therefore, while we are excavating and transporting the gold meteorite core, we must also carry out corresponding scientific exploration tasks to make full use of resources.
So for us, not only is the gold meteorite core valuable, but the stones and debris walking around the core are also valuable, so we need to collect relevant specimens and transport them back to Earth for research."
