Technological power starts with upgrading lenses

"We have basically determined its size and trajectory through photometers and ultra-telephoto optical cameras. I wanted to notify you as soon as possible last night, but your phone was turned off when I called you."

Although Kang Chi felt that there must be something in swallow, he was still a little unsure before getting an accurate reply.

Normal, as it got closer and closer to the swallow area, Tianwen-2 should have discovered something long ago, but Kang Chi never received any news, which made him even more unsure.

What if Lucy's disappearance had nothing to do with the unlocking of new elements by the system, and it was just a coincidence?

But the facts proved that his guess was right!

"Wait a minute, I'll come to you right now!"

Although Kang Chi had actually obtained the physical object made of this element material by upgrading the quantum communication chip, and after analysis, he also mastered some of the characteristics of this element,

It can be said that no one in the world knows that thing better than him,

but he was still full of curiosity about the mysterious asteroid.

Hearing the sound of getting dressed on the other end of the phone, Zhang Peirong couldn't help but smile helplessly, and then said: "You don't have to be so anxious. Swallow's orbit is slightly different from the original estimate. We may need more time to slow down and change orbits before we can conduct a close and detailed exploration of it."

"How long will it take?"

"About two days."

"That's okay, I can still wait for two days!"

...

Diameter 32468m, centrifugal force 0.0912, mass 5.56×10kg, average density 3.12×10Kg/m, surface temperature -183℃, surface gravity 0.134 g, escape velocity 0.31 km/s, albedo 0.08...

As Tianwen-2 gets closer and closer to the mysterious asteroid, more and more data are detected and calculated, and its mysterious veil is finally gradually lifted.

In the headquarters, almost all engineers of the Tianwen-2 project were shocked by the average density of this mysterious celestial body, and kept guessing what materials and elements it was made of.

An asteroid with a diameter of only 32.468 km not only has a mass of 5.56×10 kg, but also produces a gravity of 0.134 g!

In addition, the albedo of 0.08 is really too low, almost like some kind of light-absorbing material. If it weren't for the targeted close detection this time, it would be difficult to find it even with a space telescope for a hundred years.

What surprised everyone even more was that the data Kang Chi speculated at the beginning was almost the same as the actual data...

This is a bit incredible.

Looking at Kang Chi who was looking at the big screen in deep thought, Zhang Peirong suddenly couldn't help asking: "How did you do it..."

"Hmm?"

"Those data... There is no reason to deduce them just by the data released by Lucy, right?"

"Normally, it is true, but as long as you add some bold guesses, there is nothing that can't be deduced."

"..."

Speechless, Zhang Peirong had to give Kang Chi a "you are kidding me" expression.

"Okay... I confess."

Just when everyone was aroused with strong curiosity and looked at Kang Chi eagerly, he smiled and said: "Actually, I am an alien, and this mysterious asteroid is the spaceship I took when I came to Earth."

"..."

Everyone was even more speechless.

"This joke is not funny at all... We tend to take it seriously."

"Haha, whatever you want."

After a teasing, Kang Chi quickly returned to his normal expression and said in a serious tone: "Actually, don't you think it's strange?"

"Strange?"

"Although this thing has produced 0.134 g gravity, but if we enter the orbit at high speed from their perspective according to the data released by Lucy, there is no reason for us to be captured, right? "

"Well... maybe they did something with the data they released, or the data sent back by Lucy itself has problems. After all, their communication technology is too backward, and the system that had an accident is busy saving itself, so it is normal to have problems. "

"Maybe, but I always feel that something is wrong..."

"Report!"

As soon as Kang Chi finished speaking, an engineer suddenly stood up and reported in a somewhat uncertain tone: "Just now, the orbit of Tianwen-2 has an angle deviation of 0.06 degrees. It is not sure whether it is a data error or a fault in the orbit change module. "

"Angle deviation?" Zhang Peirong's face suddenly changed slightly, "Immediately perform system self-check and precision positioning. "

As Zhang Peirong's order was issued, the entire command room suddenly became busy.

"0.08, 0.11... the deviation angle is still increasing rapidly!"

"Quick, have you found the problem?"

"Don't look for it!" Kang Chi, who had been frowning, suddenly slapped his forehead, "Hurry up and start the emergency orbit change and braking procedures! We can't go forward!"

"Huh?"

Everyone was stunned for a moment, wondering why Kang Chi would stop Tianwen-2 when it was still quite far away from the asteroid.

You know, Tianwen-2 has limited fuel. When it decided to go to Swallow, it had already made a relatively large temporary orbit change, which turned into a one-way journey.

If the emergency orbit change and braking procedures are started now, it means that Tianwen-2 is likely to be able to only conduct long-distance observations of the asteroid, and the originally planned long-term orbital observation is likely to be ruined.

"magnetic field!"

Seeing that everyone was still stunned, Kang Chi quickly explained: "I know how Lucy got into the accident. The main problem is not gravity, but magnetism! This thing must have a very strong magnetic field. If you move forward, you will be sucked up. of!"

magnetic field?

This explanation made everyone stunned for a moment, and then they looked at Chief Engineer Zhang Peirong.

It’s no wonder they responded slowly. The main reason is that although there are many hypotheses about the planetary magnetic field, how it is generated is still a mystery.

But generally speaking, the larger the planet, the easier it is to generate a magnetic field. With the size of this asteroid, the probability of generating a magnetic field is almost negligible. This has led to the fact that no one, including Kang Chi, has considered this issue. .

But now think about it, since this gadget even has a gravitational field, if a strong magnetic field appears...

It doesn't seem impossible.

Zhang Peirong reacted quickly and said quickly: "Do what Mr. Kang said!"

"receive!"

"Initiate the emergency braking procedure!"

"Start calculating the corrected orbit..."

"Offset angle, 0.26, 0.67, 0.83..."

However, braking in space is not that simple. Although the speed of Tianwen-2 had slowed down from 13.8 kilometers per second three days ago, and the braking program had also adjusted the power to the maximum,

But Tianwen-2 is still rapidly approaching the asteroid at a speed of almost 3.8 kilometers per second. Not only is the deviation angle of the orbit increasing, but the braking effect is also becoming smaller and smaller...

"It's too late!"

Based on the current data, Professor Ye Hualiang silently calculated it in his mind and then suddenly shook his head and said: "The strength of its magnetic field is too high. With the thrust of Tianwen-2, the best time for adjustment has been missed. All the struggles are in vain." of."

"you mean?"

"Give up resistance, use all fuel in the 30 seconds before contact, try to gain more close detection time, and collect more data."

Zhang Peirong nodded decisively and ordered: "Stop braking and changing tracks immediately!"

"receive!"

an hour later,

With a flash of fire, Tianwen-2 finally followed in the footsteps of Lucy and crashed into this mysterious asteroid.

The entire command room was silent.
