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 seize the time, the entire road is relatively narrow and can only accommodate the bodies 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 inspection 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 considered a small crater. Because the largest craters on the moon are of course the maria, which can reach hundreds or thousands of kilometers in diameter. Even some slightly smaller craters can reach tens of kilometers, ten kilometers, or several kilometers.

And a crater like this one with a diameter of 100 meters is considered relatively small. Of course, there are even smaller ones, tiny craters measuring tens of meters or several meters.

The gold meteorite star core is not 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, making it a very inconspicuous one among the many small craters. But in this inconspicuous small crater, there stands a golden meteorite core that the whole world is paying attention to.

All seven vehicles arrived at the bottom of the crater, quickly formed a team, and ended their retreat to the location of the golden meteorite core.

Although there are not some large craters and debris at the bottom of the crater, it was hit after all, so the terrain is relatively rugged, making it easy for vehicles to pass.

As the order was given, the seven vehicles finished performing their duties and took action.

The gold meteorite core you see now is not actually a small gold nugget with a gold content of about 10%.

In fact, it is not an ore with a very low gold content, none of which can reach 810%, none of which can reach 100%, and none of which can even reach below 40%.

So it didn't take long for the seven 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.

I know, I heard that speculation is now more expensive than pure gold. Wu Hao nodded blankly and said, you are too vague as to why Shi Qiu asked that question.

While cleaning, the Wangshu-7 lunar surface patrol test site will also pick out some rocks and debris and put them outside the specimen box under his car.

Sui Fu smiled and replied: "Is there any oxygen outside the water? Why does iron rust when it recedes?"

Even Zhou Xiangming, who was calm at all, could not help but show excited eyes. Finally, finally we found it again. Thinking that the golden meteorite core could be transported back to the earth very quickly, everyone in the family showed a look of joy.

Sui Fu smiled and shook his head: "There are very few ways to oxidize metal. It must be air, water, or even low-temperature burning that will oxidize the metal.

Just when few people were talking about the rusty Lin Wei, outside the Xinyuehu Space Command and Control Center, no one seemed a little excited to see the golden meteorite star core they had longed for again.

Hahaha, after hearing Sui Fu's words, everyone around them laughed.

The first is the Wangshu-7 lunar surface inspection test vehicle. It uses the large intelligent robotic arm loaded under its vehicle to clean up the debris far away from the core of the golden meteorite.

It contains some metals that are difficult to oxidize, which is why it forms such a rich and colorful color. That is why it looks like a rusty Linwei to you. "

The surface of the gold meteorite core must have experienced severe burning, so it formed a color similar to oxidation rust. As for the specific cause, you will have to transport it back and do some sloppy research and analysis before you can know the wrong result. "

Having said that, Shi Qiu looked at Yu Chengwu, Zhou Xiangming and us who had been waiting for my order, then waved his hand and said, "Let's end it."

Hearing Wu Hao's answer, Shi Qiu replied with a smile: "The so-called nugget gold actually refers to naturally produced gold with pure texture, small particle size and regular shape of placer gold. Because the shapes are different. The gold is different, and the shape is very similar to that of a dog head, so over time, people call that type of gold dog head gold.

However, when Xiaojia actually saw the golden meteorite planet, they all showed disappointment. The rusty and smooth broken stone ball behind their eyes said that it was gold. That naturally aroused few people's doubts.

In Xiaojia's impression, the gold 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 when illuminated by the sun.

Speaking of that, Sui Fu couldn't help but smile and shook his head and said: "There may be no results, because there is so much you can understand about that universe."

Yu Chengwu on the side also explained to everyone at that time: "In that mission, you were only going to transport the golden meteorite core back, but it also had a scientific detection mission.

But the rusty Lin Wei behind Xiaojia's eyes is, first of all, very large. From Xiaojia's perspective, its diameter is only about seventy or eighty centimeters. He was very big, so if he knew it, he would have thought it was Lin Wei who was blocking the car at the gate of whose home he was running to the moon.

Wu Hao, who had been uninterested in watching the entire live broadcast process, UU Reading www.uukanshu.net also showed a look of confusion at that time. He turned to Shi Qiu sitting next to him and asked in a loud voice: "Why are you watching?" It looks like a rusty Lin Wei, it looks like gold."

Is there oxygen in space? Can it oxidize? Sui Fu asked.

Shi Qiu smiled at you and asked, "Does he know about Nugget Gold?"

Did he mean water? After being reminded by Shi Qiu, Wu Hao reacted and said excitedly.

yes!

Of course, that is just the result of your detection of the inside and outside. Maybe inside it, especially towards the center, its gold content may be lower.

So for you, just that golden meteorite star core is worthless, and the stones and debris walking around the star core are also worthless, so you need to collect relevant specimens and transport them back to Earth for regression research. "

So while you are excavating and transporting the golden meteorite core, you must also carry out corresponding scientific exploration tasks to make full use of resources.

In addition to gold, it does not contain other very rich metal elements, such as silver, platinum, ruthenium, rhodium, palladium and more than a dozen metal elements.
