Wu Tegong, the captain of the Cicada-class 004 spacecraft, looked at the holographic model that was fed back by the detection system and then integrated.

"Captain, there are still 411 seconds left, and we will pass by the target...... "Radar officer Lin Mingyu reminded.

Utgong thought for a few seconds, and then ordered: "Continue to monitor, use the highest precision detection system." ”

"Roger." Lin Mingyu opened a set of high-precision detection systems for scientific research, and suddenly the contours of the target and the internal situation on the holographic projection became clearer.

It's just that as the two sides get closer and closer, Utgong has become more and more cautious in his heart.

Another analyst, Diatt, also saw very strange data: "Captain, the metal composition of this asteroid is very high, especially the surface, which is rich in high-density lead, which is a bit like ......"

After 200 seconds.

The distance between the two sides is 130,000 kilometers.

At this point, the data returned by the probe is more accurate.

And Utgong, Diat, Lin Mingyu and others all noticed the problem.

Because of the data fed back from the magnetic field detector, it can be analyzed that the asteroid is very "regular", and even a little abnormal.

Utgong quickly picked up the panel and entered the command of the headquarters data cohomology.

Suddenly, on Earth in the interior of the solar system.

In the command center of the Interstellar Exploration Office, all the data of the Cicada-class 004 spacecraft are transferred to the command center.

Hill, as the person in charge of the command center, immediately contacted Utgong, and it took less than twenty seconds for the two sides to communicate.

At this time, Hill immediately ordered everyone to cooperate with the work of the Cicada-class 004 spacecraft, and she was also watching the situation of the asteroid, and the more she looked at it, the more she felt that something was wrong.

Especially as the distance between the two sides approaches 30,000 kilometers, the situation becomes even more obvious.

Hill immediately decided: "Captain Utkorn, slow down immediately, and then accompany this asteroid." ”

"Roger."

The Cicada-class 004 spacecraft quickly detonated a relatively large hydrogen bomb in front of the spacecraft, and in an instant, the huge reaction force caused the spacecraft to drop its speed to 353 kilometers per second.

Immediately afterward, another deceleration hydrogen bomb was detonated.

After five hydrogen bombs were detonated in succession, the speed of the spacecraft dropped to 18 kilometers per second, slightly higher than the asteroid's speed of 15.2 kilometers per second.

When the cicada-class spacecraft was first designed, two thrust reverser lids were specially designed, and the mass of these two lids alone reached about 4,200 tons.

If it weren't for these two lids to block the radiation and high-energy particles of the hydrogen bomb, the instruments and equipment in the middle and the cockpit would have been full of holes.

This kind of super deceleration, if the astronauts are allowed to drive the spacecraft, is estimated to squeeze the astronauts into meatloaf in an instant.

Only by using synchronous robots can we resist this instantaneous slowdown.

Utgong and co-pilot Zheng Lin hurriedly activated the nuclear power thruster and began to adjust the direction of flight, after all, the asteroid did not fly towards the inner circle of the solar system, but towards an oblique angle, towards the outer layer of the Cooper belt.

If the asteroid's direction does not change, it will pass by the solar system in a few hundred years and enter the vast void interstellar space again.

And Cicada-class 004, which gave up continuing to fly outward, is also rapidly approaching the asteroid at this time.

As the distance between the two sides approached to 1000 km.

At this time, the outline and interior of the asteroid become clearer.

Diat looked at the stratigraphic profile model of the asteroid in amazement: "This thing is a bit of a man-made thing!" ”

But Utgong did not take it lightly, but turned his head and ordered: "Mingyu, probe closely, especially the heat source reaction." ”

"Understood." Lin Mingyu nodded.

Half an hour later.

The spacecraft successfully flew at a distance of 37 kilometers from the asteroid, and after some adjustments, a relative balance between the spacecraft and the asteroid was maintained.

At this time, in the cockpit of the spacecraft, Utgong and others saw a very clear internal structure of the asteroid.

"This thing is completely man-made!" Diat pointed to the dense pipe-like cavities and the mass of well-defined metal structures.

The asteroid with a radius of 23~86 kilometers in front of you is clearly a spaceship.

Lin Mingyu reported to Utgong: "Captain, there is no high heat source reaction inside the target, and its internal temperature is between minus 86~89 degrees Celsius. ”

"Aren't there any hot spots? Continue to monitor again. ”

"Yes."

Utgong did not immediately send a probe over, but continued to observe the spacecraft.

The spacecraft has a length of 86 km, a width of 23 km, and a height of 19 km, and is covered with three layers of lead plates, most likely a protective layer against radiation.

The surface of the ship is full of craters, there are several relatively large holes, and there is a lot of ice on the surface.

It looks like a long time has passed.

"Generation ships?" Utgong was thinking, and suddenly he called up another data and checked the direction of the ship's flight.

Through supercomputer analysis, the navigation route of the spacecraft was quickly analyzed, and although the direction may be changed halfway, there is a high probability that it will not deviate too much.

Utgong brought himself into the perspective of the commander of this spaceship, and it was obvious that the other party's destination was the solar system, but it was obvious that the ship had deviated a lot.

It's just that Utgong feels a little strange, logically speaking, the closest planetary system to the solar system on the route of this spacecraft is also about 18.4 light years.

If this spacecraft really flew from the direction of 18.4 light years, it was obviously illogical, because there were two other planetary systems around the planetary system at 18.4 light years, and the distance was several times closer than the solar system, and the other party had no reason to go far.

Of course, there is another possibility, that is, there are two civilizations in those three planetary systems, and a war breaks out between the two sides, and the defeated side can only run away in the direction of the solar system.

The problem is that this one is probably not very big.

The reason why it is not big is that the distance between the three planetary systems is about 5.3 light years at the earliest, which is difficult to expand without faster-than-light transportation technology.

Utkorn discussed his views with the team members.

Others were also very confused.

After all, at the speed of this spacecraft, if it really wants to cross 18.4 light years and come to the solar system, it will be difficult to reach the sky.

"Captain, it's actually useless for us to guess here, why don't we send a probe to land?" Diat suggested.

But Utgong shook his head: "No, don't forget the interstellar management regulations, without the instructions of the headquarters, it is strictly forbidden to contact with unknown alien civilizations, and we don't know if there is any danger above." ”

In fact, on the earth side at this time, the space division has quickly held an internal meeting and notified the chairman Li Qingye.

They are also thinking about how to deal with the spacecraft.

The exploration is definitely going to continue.

But how to explore this is a very important topic.

After all, Homo sapiens is not the protagonist of SB in European and American movies, and it will certainly not land on the spaceship of an unknown civilization unprepared.

This is also the reason why Cicada-class 004 chose to fly with it at the beginning, rather than landing directly.

Because there is an unpredictable risk of directly contacting a spaceship of an unknown civilization without preparation, which is strictly forbidden by Homo sapiens.

After launching a program to explore the outer space of the solar system, Homo sapiens ordered the Space Division to develop a strict management plan to prevent this kind of thing.
