Du Yun's hometown is not far from Tianqu City, and it is now a lower county in Quancheng, the provincial capital, but more than 20 years ago, this county was under the jurisdiction of Tianqu City, that is to say, Du Yun is actually a real fellow countryman and Tang Feng, a city.

The people of Lu Province have been known for their bold personality since ancient times, especially the men of Lu Province, who have been known as "the great Han of Lu Province" since ancient times. Even with it, most of the women in Lu Province are more bold, they look at you and dare to tell you anything, they don't like you, they stay where they are cool, and they are not pretentious at all.

As a woman born in Lu Province and raised in Lu Province, Du Yun has been in the army for more than ten years, and her personality and temper are even more bold like a man in Lu Province.

As early as when selecting astronauts, Tang Feng saw all of Du Yun's information, and later when they were training together, the relationship between the two became better and better. Of course, this kind of relationship is not the kind of relationship between men and women, but a relationship similar to that between sisters and brothers.

Tang Feng is a few days younger than Du Yun, but even if he is an hour younger, he is still a younger brother. So after more than a month of contact, Du Yun has a lot of words that never avoid Tang Feng.

"Sister Du, if you don't wait to go back, I'll introduce you to one. There are two options, one is older than you, the family is rich, and the people are quite nice, but the home is from the south. There is another one who is younger than me, and he is also a northerner, but he is very sincere, and now he is mixing with me, and the conditions are very good. How about it, Sister Du, think about it? Tang Feng said with a grin. The two people Tang Feng said, one is the boss Zhang Mingfeng, and the other is naturally the third Li Zimu.

Needless to say, the conditions of the boss Zhang Mingfeng are properly rich second generation, and these old bosses have grown up, and some important projects in the family are now starting to be handled, plus the boss is good-looking. is a little handsome, so Tang Feng thought of him first.

It's just that the boss's temper is a little introverted, and Tang Feng is worried that the temper between the boss and Du Yun will not get along, after all, Du Yun's personality is really like a female man.

As for Li Zimu, although the conditions are not as good as the boss Zhang Mingfeng, he is now a proper millionaire. has a personality or something, and he is more compatible with Du Yun, and the only drawback is that he is more than two months younger than Du Yun.

"What? Want to be a matchmaker for my sister? Du Yun asked with a smile.

"Yes, I think my vision is still good, the boyfriend you introduced to Sister Du must be no problem, with Sister Du, you will definitely not let you drop the price."

"Well, I trust your vision. When you get back, you can introduce me and see how it goes. But when it comes to the ugly words, if I don't like it, don't blame my sister for not giving you face. ”

"Where, where, the blind date is originally a matter between two people, and the so-called matchmaker leads the door. Get along personally. Whether you can talk together or not, that's between you. I'm a leader."

The two of them were chatting and chatting, and the headset rang with Han. Positive voice: "Tang Feng, we are down, get ready." ”

Tang Feng and Du Yun immediately stopped chattering, and Tang Feng thought about it. First hugged the "meteorite" and walked into the distance, and said as he walked: "I'll stay away first, wait for Brother Han to move the nuclear battery down, you will experiment on the Mars rover first, and then pay attention to the power of the nuclear battery." I'll carry this meteorite with me again. ”

Du Yun nodded, knowing why Tang Feng did this. After Tang Feng walked out for several hundred meters, Han. Zheng and Robin. Only then did Coroso climb down the elevator with two nuclear batteries on his back.

Han. Zheng and Robin. Korosso also heard Tang Feng's words just now, and after he came, he immediately removed the nuclear battery on his back and replaced it with the two lunar rovers. Not surprisingly, these two nuclear batteries are really fine, and the power is very sufficient.

"Tang Feng, come here, we will pay attention to the power of the nuclear battery." As a result, when Tang Feng walked to a distance of about 100 meters from the lunar rover, the original power of the nuclear battery, which was still 100%, dropped rapidly at an extremely fast speed.

Tang Feng hadn't reached fifty meters yet, and a nuclear battery that was enough for a lunar rover to last twenty years had become empty

and Robin. After Coloro hurriedly replaced another nuclear battery, the same thing happened.

Obviously, the sudden failure of this nuclear battery was caused by the "extraterrestrial meteorite" of unknown origin. As for why this happened, these people didn't know why except for Tang Feng.

After Tang Feng came over with the "meteorite" in his arms, he put the "meteorite" on the ground and asked, "Is this guy only effective for nuclear batteries?" How can the ordinary batteries in the spacesuits on our bodies be okay? ”

Hearing Tang Feng say this, Du Yun, who is an electronics expert, immediately said with a sudden realization: "Could it be that this meteorite only works on radioactive elements?" ”

Another name for a nuclear battery is a "radioisotope battery", which is made by converting the thermal energy of the isotope into electrical energy by converting the isotope into electrical energy during the decay process by continuously emitting rays with thermal energy during the decay process.

Nuclear batteries and nuclear reactors are two very different concepts, nuclear reactors use the huge energy emitted by nuclear fission to generate electricity, while nuclear batteries use isotopic decay to produce electric current.

But in any case, neither a nuclear reactor nor a nuclear battery can do without radioactive elements.

As soon as Du Yun said this, the faces of several people suddenly became extremely ugly. The value of this meteorite is absolutely incredible, not to mention that this function that can target radioactive elements alone has scientific research value, so if you bring this meteorite back to Earth, it is definitely more valuable than bringing a few tons of lunar rock samples.

But the problem is that the main engine of the lunar spacecraft is to use a nuclear reactor as a power source, and if this meteorite is really lethal to radioactive elements, then doesn't it mean that once this meteorite is brought to the lunar spacecraft, the lunar spacecraft will have no way to act?

can become a one-in-a-million astronaut, these people can be called masterpieces, of course they will want this kind of thing. So for a while, several people looked at each other.

Throw away this meteorite, it's really unwilling, but how to bring this meteorite back has really become a big problem. (To be continued.) )
