The latest data from the probe sent to the surface of Venus suggests that Beneath the planet's dense clouds is a hot, dimly lit surface. The data shows that as the topography beneath the clouds changes, there will be climatic ripples at the top of the clouds, and the three elements of wind, water and clouds have a subtle relationship with the surface of Venus.

Gu Cheng didn't pay much attention to other data, he only cared about whether the water on this planet was enough for the future environmental transformation of the earth, which was also the biggest purpose of this exploration of Venus.

As for other research, interested scientific research institutions can just make it if they like it.

Obviously, the result made Gu Cheng quite satisfied.

Zhou Huang came to the extraterrestrial detection and control center at this time, "Boss, NASA Administrator Jim Bridenstine has come to the company and asked to meet you immediately, 100,000 urgent." ”

Gu Cheng couldn't help but be stunned, what kind of fame are Americans doing? Still in a hurry?

"Wait, you're saying NASA Administrator came to the company in person? Already here? ”

Seeing Zhou Huang nodding affirmatively, it seemed that he was really in a hurry, Gu Cheng immediately left the Extraterrestrial Planet Exploration and Control Center, went to meet Jim Bridensteen, and returned to the Hive Headquarters in about ten minutes, and met again with the NASA director in a reception room.

When Gu Cheng was about to say a few polite greetings, Jim Bridenstine and several North American scientists who came with him all stood up, and he directly took the lead and said, "Mr. Gu, the human race is in big trouble. ”

“？？？”

As soon as they met, Gu Cheng was also stunned for a while, and Jim Bridenstine hurriedly said regardless of his reaction: "Just 27 hours ago, PDCO detected a near-Earth asteroid with a diameter of about 5 kilometers at a distance of 875,000 kilometers from the Earth. ”

At this moment, Gu Cheng had already come back to his senses, and when he heard this, he subconsciously said, "Don't tell me that this thing will hit the earth?" ”

At this time, a man with glasses standing next to the NASA director said: "Unfortunately, it is flying towards our Earth, and the relative speed of approaching the Earth has exceeded 33 km/s." ”

Gu Cheng glanced at him: "Are you ......?" ”

Jim Bridenstine immediately explained: "Worthen, he's currently playing for PDCO. ”

The so-called PDCO, short for "Planetary Defense Coordination Office", is an agency under the direct jurisdiction of NASA, but it was not established to deal with aliens, but to deal with the threat of asteroids.

Gu Cheng was also a little stunned at this time, he could already see from the other party's expression that he was not joking, and it was impossible for the then head of NASA to suddenly fly half the world to come and make fun of him.

At this time, the reception room was quiet, and Gu Cheng took a deep breath, "5 kilometers, 5 kilometers in diameter, why has such a large near-Earth object not been discovered until now?" ”

This news made it difficult for Gu Cheng to calm down, its size is equivalent to half the size of the Chicxulub meteorite, which is now widely believed to be the main cause of the mass extinction of dinosaurs.

If this asteroid that is flying towards the Earth collides, there is no doubt that 99% of the achievements that mankind has built so far will be destroyed, and the catastrophe will be global and devastating.

This collision, even if it does not completely destroy all mankind, will basically drive humanity back into the cave to live a primitive society.

Walzen looked at Gu Cheng and said: "In fact, this asteroid has been discovered in 1983 and has been listed as a 'potentially threatening asteroid' by PDCO, this asteroid is codenamed '3200 Christmas Eve, this asteroid has visited our planet, and the closest distance to the earth at that time was about 10.3 million kilometers. ”

The asteroid is named after Phaethon, the son of Helios, the god of the sun, and Cleomene, the goddess of the sea, in Greek mythology, who symbolized the "burning of the fire" and drove the sun god Apollo out of control and plunged the world into a sea of fire.

"The last time it approached Earth, we found a stream of dust ejecting from its surface, similar to how comets produce comet tails, but its orbit shows that '3200Phaethon' was born in the asteroid belt between Mars and Jupiter, which is rich in asteroids," Watson continued. It is strange that '3200Phaethon' should not have approached Earth at this time, and after visiting Earth in 2017, it should not return until 33 years later, but it was more than 20 years earlier. ”

In the end, Gu Cheng didn't have the heart to be unbelievable, and immediately said, "How many hours are left until the impact time?" Where exactly is the impact site? ”

He had already swept within a million kilometers of space, and he didn't even want to count it in days.

"Ten days at most, maybe nine days, the exact impact site has not been calculated, this is a multi-body problem, the closer the asteroid is to us, the greater the uncertainty, the Earth and other celestial bodies are gradually perturbing it is gradually increasing, it is not easy to calculate the exact orbital impact site," Worthen said. ”

Hearing this, Gu Cheng couldn't help but nodded, and immediately looked at Jim Bridensteen: "So, you came here and want to borrow my Sky Arc No. 1?" ”

Jim Bridenstine nodded affirmatively, Tianarc-1 is currently the most advanced supercomputer in the world, and has undergone many upgrades and iterations, and it can defeat it, I am afraid that only quantum computers, but so far the technology of quantum computers has not been broken through.

In fact, this is not the main purpose of the other party's coming, another more important reason is that in the face of such a major extraterrestrial object threat, the power of the national level is secondary, because the whip is beyond the reach, and heavyweight players in the field of space exploration such as Tianqing Technology will play a greater effect.

To put it simply, the scientific and technological workers are the protagonists, and everything else is secondary.

Gu Cheng noticed several Americans who came with Jim Bridensteen, one of whom was carrying a portable black box, which contained most of the parameter data brought by NASA this time.

"Come with me." Gu Cheng didn't hesitate too much, and at the same time instructed Zhou Huang beside him: "Xiao Zhou, you immediately stop all the project processes that are currently running in the Sky Arc No. 1, and free up all the computing resources, pay attention, don't make noise everywhere, this is a horror story." ”

"Understood." Zhou Huang nodded in response.

Of course, he knows which matter is more serious, if this is exposed, the asteroid has not yet come, and the human race on the earth will definitely collapse first.

So far, astronomical agencies of various countries on the earth have discovered this asteroid one after another, and roughly calculated its orbit, all of which have been pressed to death by various countries, all of which have the same caliber.

While preparing for the worst, while waiting for news from PDCO, in the area of near-Earth asteroid defense, only NASA has invested the most resources, and the time has been around for a long time, so PDCO is the key at this time.

Now, the general public around the world, what to do, do not know that "Phaethon" is coming.

……

Sky Arc No. 1 supercomputer room.

Gu Cheng and others and NASA and other Americans are waiting for the supercomputing results, which are expected to be calculated in about four and a half hours, and everyone is anxiously waiting.

While waiting, Zhou Huang took a whiteboard and made a sketch of the Earth-Moon system, and muttered to himself: "Is it possible for the Asteroid to be captured by the satellite?" I mean, how big is it likely to hit the moon? ”

He didn't speak English, and when Worthen next to him heard the translator, he immediately said: "In the current situation, the theoretical probability of hitting the moon is 1 in 10,000. ”

1 in 10,000 probability......

The implication is not to have such unrealistic illusions.

Finally, after more than four hours of waiting, the results of the supercomputer verification are finally out!
