Chapter 699: A Meteorite
Shenzhou began to change its orbit inward from the geosynchronous orbit and entered the return procedure.
"A meteorite appeared ahead, about five meters in diameter, which was expected to be captured by the Earth's gravity and fall into the atmosphere." The crew of the Shenzhou found an unidentified flying object on the radar, and after confirming it through observation, it was reported.
"Five meters in diameter? This meteorite is a bit big. Han Youwei's first reaction was that this meteorite was too big.
Eve wasn't quite sure, frowned and asked, "Youwei, will this meteorite hit the ground?" ”
"It's not 100% sure that it can hit the earth, it depends on the density of the meteorite and the main material. If it's ice, it's burned out in the atmosphere. If the main element is iron, it will definitely hit the ground, and it will be huge. Han Youwei took a look at an article about meteors and meteorites that she had read before.
"So a meteorite with a diameter of five meters, isn't it very big?" Eve wasn't sure.
"If the main material is iron and rock, this diameter is already very large, and if it is ice, there is no need to worry." Han Youwei explained again.
Niu Dazhi scratched his head and asked strangely: "Is the meteorite still made of ice?" ”
"Of course, the temperature in the universe is very low, most areas are close to absolute zero, is it strange that there are ice cubes?" Eve instinctively turned back at him.
Fang Yuan had a general understanding of 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 dense. According to this mass, after being captured by the Earth's gravity, it will fall into the atmosphere and become a meteor and smash into the ground. The impact will be very powerful, and if it is smashed into the city, the situation will be worse.
"However, most of the earth is ocean, and even if it is land, the proportion of cities is relatively small, so the probability of smashing into a city 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?" ”
A meteorite with a diameter of five meters, if it hits the ground, is indeed quite terrifying.
However, for Fang Yuan, one punch could blow it up.
Yang Yuping waved his hand and dissuaded: "It's not suitable for smashing, after shattering, the fragments will fall into the atmosphere, and they will indeed burn out, so you don't need to worry about hitting the ground."
"However, your current position is in geosynchronous orbit of the Earth, where a large number of satellites exist. If this meteorite is broken, a lot of debris may be scattered into the synchronous orbit, and hitting the satellite is a huge loss. ”
Fang Yuan bowed his head and said, "That's right, then directly pull this meteorite into the spaceship and bring it back to the ground." Is this a good solution? ”
"This scheme is possible, and meteorites also have research value. It's just that in the test flight plan of Shenzhou, there is no plan to leave the spacecraft and return with space materials, so you need to apply to the headquarters. Yang Yuping frowned, he didn't want the return of the Shenzhou to have an accident, so he had the idea that it was better to have more than one thing.
"Then apply to headquarters. I went out and brought the meteorite in. Fang Yuan felt that this plan was feasible.
"Wait, don't worry." Yang Yuping turned back to discuss with other scientific researchers.
Ten minutes later, the decision of headquarters was handed down.
Yang Yuping sat in front of the video communication and said in a serious tone: "Fang Yuan, the headquarters agreed to your plan. However, there are 32 tests to be done before exposure to meteorites.
"Confirm the main material composition of the meteorite, as well as the presence or absence of radioactivity, etc.
"After confirming that there were no problems with all the tests, the meteorite was towed into the A1 transport module of the Shenzhou, and the A1 transport module was completely blocked.
"All personnel who come into contact with the meteorite must go through strict quarantine and disinfection before returning to the cockpit."
Fang Yuan knew that these steps were necessary, and they all nodded in agreement.
An exotic meteorite, there may be many possibilities.
If there is a large amount of radioactive elements in the meteorite, human contact can cause physical lesions.
Therefore, radioactivity testing is a must.
Similarly, there is quarantine and disinfection.
Although the probability of encountering extraterrestrial creatures in the universe is low, there is still a possibility.
Extraterrestrial creatures include not only intelligent creatures such as humans, but also bacteria and viruses.
Therefore, exotic meteorites may also have viruses and bacteria from other planets.
If this alien microorganism does enter the earth, it may cause a catastrophe.
Although the odds of this happening are slim, if it happens, the consequences are unimaginable.
"Take Zhao Anya over, conduct a comprehensive inspection of the meteorite, and then drag it into the transport compartment of the Shenzhou." Yang Yuping finally emphasized again.
"Okay, got it." Fang Yuan agreed and glanced back.
Zhao Anya has already equipped the battle suit with the oxygen supply system required for space, and a small power plant.
Because she doesn't have the ability to fly in space, she needs to equip her suit with a power plant to avoid drifting in space and not being able to return to the spaceship.
Of course, there is a source of the party, and the probability of this happening is very small, but the power unit still has to be installed.
After receiving permission from the headquarters, the Shenzhou changed direction slightly and flew in the direction of the meteorite.
When approaching a distance of three kilometers from the meteorite, the operation to capture the meteorite officially began.
Fang Yuan and Zhao Anya walked through the long passage of the Shenzhou, and before they walked to the exit gate, the passage behind them had been closed, isolating the air.
Fang Yuan glanced sideways at Zhao Anya and asked, "Are you nervous?" ”
Zhao Anya spread her hands and asked rhetorically, "What is there to be nervous about?" ”
"This is supposed to be your first mission to outer space, right? Without any training, running out into outer space sounds exciting. Fang Yuan said with a smile.
"I don't think it's a problem, it's like swimming in the ocean." Zhao Anya was not worried at all.
After all, there are several super soldiers in the Shenzhou, and even if there is an accident, it can be remedied, and there is really no need to worry.
The gate slowly rises upward.
Since there was no air in outer space, the air in the passage rushed out as if it were blowing a strong wind.
The two reached out and grabbed the edge of the door, pushed it hard, and flew forward.
Eve was in the second co-pilot seat of the Shenzhou and reported the location of the meteorite: "The meteorite is in front of you on the left, three kilometers away. ”
Fang Yuan's flight speed was fast, he flew over first, and then the instrument on his back did an all-round scan of this meteorite.
The meteorite is very large, five meters in diameter, which is equivalent to the height of a two-story building.
After a while, Zhao Anya arrived and used "starenergy spectroscopic analysis" to examine the meteorite.
All checks were completed and the data was initially analysed before a response was received from the ground command center.
"Everything is fine with the meteorite, you can bring it back."
When Fang Yuan heard the order, he reached out and held down the meteorite, pushed it in the direction of the Shenzhou, and dragged it into the A1 transport cabin.
