Chapter 699: A Meteorite

Shenzhou began to change its orbit inward from the geosynchronous orbit and entered the return procedure.

"A meteorite appeared ahead, with a diameter of about five meters. It is expected to be captured by the gravity of the earth and fall into the atmosphere." The crew of Shenzhou found a UFO on the radar, confirmed it through observation, and reported it.

"Five meters in diameter? This meteorite is a bit big." Han Youwei's first reaction was that the meteorite was too big.

Eve was not very sure, she frowned and asked, "Youwei, will this meteorite hit the ground?"

"It's still not 100% sure. Whether it can hit the earth depends on the density and main material of the meteorite. If it is ice, it will be burned up in the atmosphere. If the main element is iron, it will definitely hit the ground. , and the power is huge." Han Youwei discussed an article about meteors and meteorites that she had read before.

"So the meteorite with a diameter of five meters is very large?" Eve was still not sure.

"If the main material is iron and rock, this diameter is already very large. If it is ice, there is no need to worry." Han Youwei explained again.

Niu Dazhi scratched his head and asked strangely, "Are meteorites still made of ice?"

"Of course, the temperature in the universe is very low, and most areas are close to absolute zero. Is it strange that there are ice cubes?" Eve instinctively turned to him.

Fang Yuan roughly understood the data of this meteorite, and asked: "Can you confirm the main material of this meteorite?"

Zhao Anya replied: "From the perspective of spectral analysis, the main elements are iron and silicon, which are relatively dense. According to this mass, after being captured by the earth's gravity, it will fall into the atmosphere and become a meteor that hits the ground. The impact force will It is very large, and if it smashes into the city, the situation will be worse.

"However, most of the earth is ocean. Even on land, the proportion of cities is relatively small, so the probability of smashing into cities is relatively small."

Fang Yuan thought about it, looked at Yang Yuping in the video communication, and asked: "Professor, do you need to break this meteorite?"

If a meteorite with a diameter of five meters hits the ground, its power is indeed quite terrifying.

However, for Fang Yuan, one punch can blow him up.

But Yang Yuping waved his hand and dissuaded him: "It's not suitable for smashing. After smashing, the fragments will fall into the atmosphere and will indeed burn up.

No need to worry about hitting the ground.

"However, your current position is in the geosynchronous orbit of the earth, and there are a large number of satellites there. If you break this meteorite, many fragments may be scattered into the synchronous orbit, and hitting a satellite is a huge loss."

Fang Yuan nodded and said: "That's right, then just pull this meteorite into the spaceship and bring it back to the ground. Is this plan okay?"

"This plan is possible. Meteorites are also valuable for research. However, in the Shenzhou flight test plan, there is no plan to leave the spacecraft and return with space materials, so you need to apply to the headquarters." Yang Yuping frowned, not I hope that there will be an accident on the return voyage of the Shenzhou, so I hold the idea that it is better to do less than to do more.

"Then apply to the headquarters. I'll go out and move the meteorite in." Fang Yuan thinks this plan is feasible.

"Wait, don't worry." Yang Yuping turned around to discuss with other researchers.

Ten minutes later, the decision from the headquarters was handed down.

Sitting in front of the video communication, Yang Yuping said in a serious tone: "Fang Yuan, the headquarters has agreed to your plan. However, before touching the meteorite, 32 tests must be done.

"Confirm the main material composition in the meteorite, and whether there is radioactivity and other information.

"After confirming that there are no problems with all the tests, the meteorite will be dragged into the A1 transport cabin of the Shenzhou, and the A1 transport cabin will be completely sealed off.

"All personnel who come into contact with the meteorite must undergo strict quarantine and disinfection before returning to the cockpit."

Fang Yuan knew that these steps were necessary, they all nodded in agreement.

There may be many possibilities for an alien meteorite.

If there are a large amount of radioactive elements in the meteorite, human beings may suffer from physical lesions if they come into close contact.

Therefore, radioactive detection must be done.

Likewise, quarantine and disinfection.

Although the possibility of encountering alien life in the universe is very low, it is still possible.

Alien creatures include not only intelligent creatures like humans, but also bacteria and viruses.

Therefore, alien meteorites may also contain viruses and bacteria from other planets.

If this alien microorganism really enters the earth, it may cause a disaster.

Although the chance of this happening is very small, once it happens, the consequences will be disastrous.

"Take Zhao Anya there, and after a comprehensive inspection of the meteorite, it will be dragged into the transport cabin of the Shenzhou ship." Yang Yuping emphasized again at the end.

"Okay, got it." Fang Yuan agreed, and looked back.

Zhao Anya has already assembled the oxygen supply system needed for space and a small power plant on the battle suit.

Because she does not have the ability to fly in space, she needs to be equipped with a power device on her battle suit to avoid floating in space and being unable to return to the spaceship.

Of course, with Fang Yuan present, the probability of this happening is very small, but the power unit still needs to be installed.

After getting permission from the headquarters, the Shenzhou slightly changed its direction and flew towards the meteorite.

When the meteorite was close to a distance of three kilometers, the operation to capture the meteorite officially began.

Fang Yuan and Zhao Anya walked through the long passage of the Shenzhou, and when they reached the exit gate, the passage door behind them was closed, cutting off the air.

Fang Yuan glanced sideways at Zhao Anya, and asked, "Are you nervous?"

Zhao Anya spread her hands and asked, "What's there to be nervous about?"

"This should be your first outer space mission, right? It sounds very exciting to go for a stroll in outer space without any training." Fang Yuan laughed.

"I don't think it's a problem, it's about the same as swimming in the sea." Zhao Anya wasn't worried at all.

After all, there are several super fighters on the Shenzhou, even if something happens, it can be remedied, so there is really no need to worry.

The door slowly went up.

Since there is no air in outer space, the air in the passage gushes out like a gust of wind.

The two reached out and grabbed the edge of the door, pushed hard, and flew forward.

Eve reported the location of the meteorite in the second officer's seat of the Shenzhou: "The meteorite is in front of you on the left, three kilometers away."

Fang Yuan's flying speed was fast, he flew over first, and then the instrument on his back scanned the meteorite in all directions.

This meteorite is very large, five meters in diameter, equivalent to the height of a two-story building.

After a while, Zhao Anya arrived and used "star energy spectrum analysis" to inspect the meteorite.

After all the inspections were completed and the data was preliminarily analyzed, the reply from the ground command center was received.

"The meteorite is all normal and can be brought back."

When Fang Yuan heard the order, he stretched out his hand to hold down the meteorite, pushed it in the direction of Shenzhou, and dragged it into the A1 transport cabin.
