Half-immortal civilization

The position of the asteroid is not directly in front of the route, but in a diagonal direction.The vertical distance from the spacecraft's course is about 3 kilometers.This distance, in space, is really very close.

"Scan the distance. Calculate the time." The new Dream space shuttle already has a full speech recognition system.And it has been 10 minutes since the asteroid was scanned, and it must be scanned.

"The scan is complete, and now the asteroid is 58 kilometers behind the spacecraft, with a speed of minus 966.25 kilometers relative to the spacecraft.

To finish capturing an asteroid, you need to slow down first.Note that you now have an initial velocity of 1000 kilometers per second because you are following the spaceship.Then drag the asteroid with a mass of up to 3100 tons to accelerate to catch up with the spacecraft.According to calculations, you are not carrying enough electricity.

After comprehensive computer analysis, unless you want to die, don't try to capture that bastard.

You should now turn off the engine and follow the spaceship forward. "

Pfft... Lin Yun sputtered, "This is the smart program made by the science and technology department!"

"Captain, it's a semi-intelligent program." Wang Sheng next to him had a look of embarrassment on his face: In fact, I just set the program because my hands were itchy!

"Okay, I can only give up. Report to the general control that the 301 aircraft has canceled the plan to capture the asteroid; but it will not return to the spacecraft for the time being, and will circle the spacecraft."

"Received by the master control. Please pay attention to safety and try not to leave the magnetic field protection layer of the spacecraft. In addition, due to the influence of the sun's gravity, the speed of the spacecraft has now been reduced to 996 kilometers per second. When the speed of the spacecraft is lower than 900 kilometers, it will It will accelerate. Please pay attention to control your speed."

"Thank you." Lin Yun switched the communication to Zhang Jianye: "Scientist Zhang, I'm sorry, our actions are too slow, and the asteroid is already 58 kilometers behind us. It is no longer worth capturing."

"Oh, it doesn't matter. I was negligent. Just now, I just heard from the main console that you are not going to return to the voyage, so stay in space for a while. Well, another asteroid was discovered. 19 kilometers in front of the spacecraft place."

"Okay, I'll try my best." Lin Yun could only try to capture this asteroid.

"Auto Scan."

"Didi... The scan is complete. The maximum diameter of the asteroid in front is 9 meters, and the minimum diameter is 7 meters. Spectral analysis shows that it is mainly composed of three elements, silicon, oxygen and iron, with a weight of about 1300 tons and a speed of 35 kilometers per second.

The vertical distance from the orbit of the spacecraft is 4 kilometers, and the closest time is expected to be 190 seconds later.

Calculated according to the acceleration of the aircraft at 500 meters, it takes 4 seconds to cross 179 kilometers. Theoretically, the time is enough to operate.But it has to start now. "

"Start, 50 times the acceleration of gravity!" Lin Yun started immediately without hesitation.There are many asteroids in space, but there are few asteroids that are just in the direction of the spacecraft.

"Beep...the computer is calculating the safety. The plane's current speed is 1000 kilometers, and after 178 seconds of lateral acceleration, the estimated speed is 1004 kilometers per second. The speed of the asteroid is only 35 kilometers per second.

If you want to complete the asteroid capture plan, after safety calculations, the answer is: don't drag me into the water if you want to die! "

"Asshole. Which programmer designed this!" Lin Yun was so angry.The smart program looks like this, it really makes people feel Alexander.

Wang Sheng's head next to him is even lower, is it because his hands are itchy and set to a cold humor mode? As for this!This is what I didn't expect, cold humor is such a way.

However, although the calculated answer is rather weird, it has to be said that this is indeed an act of death.

The speed difference between the two is so large, even if it passes through the carbon fiber net, it will eventually cause great harm to the space shuttle.

However, fortunately, after the last capture of the asteroid Apophis, the carbon fiber net dragging technology has been improved, and that is the use of elastic technology.In order to meet the safety requirements, the carbon fiber mesh can be pulled up to a distance of 10 meters, and the high-strength nano-carbon fiber is enough to drive nearly a thousand tons of pulling force, which is enough to be used as a high-end space material.

Of course, the speed difference between the two is a bit big, and doing so still has certain risks.And if the pulling force is greater than a thousand tons, the space shuttle will automatically activate the safety device and eject the carbon fiber device from the aircraft.

With 50 times the acceleration of gravity, Lin Yun, who was only on the seventh floor of the Qi training period, and Wang Sheng, who was on the sixth floor of the Qi training period, felt a little on the verge of death.This feeling is really terrible, as if his own weight is about to crush his chest, and his heart is tightly attached to his back.

Inside the aircraft cabin, the engine rumbled.

With an indomitable momentum, the plane began to accelerate violently perpendicular to the direction of the spacecraft.

In space, a space shuttle moves horizontally at a speed of 1000 kilometers per second, while accelerating vertically at an acceleration of 500 meters!
In fact, the real direction of flight of the aircraft is a diagonal direction.

"It's getting close, we need to slow down, or we will miss it. The engine needs to be turned off!" Wang Sheng helped.

"At a distance of 3000 meters, we will pass 100 meters above the asteroid. The time is only one thousandth of a second, and the automatic capture system will be activated."

"Beep... touch!" Amidst the loud noise, a mass of gray carbon nanofiber network popped out, accurately covering the entire asteroid.

At this time, the space shuttle quickly passed the surface of the asteroid, and it was about to go away with a bang.

The carbon fiber tensed instantly, and slender carbon fibers continuously extended from the butt of the plane.In an instant, there was a reaction force of up to 800 tons, acting on the plane.The plane creaked.

The computer automatically reports "instant speed, the space shuttle is 1004 kilometers per second, the asteroid speed is 33 kilometers per second, and the carbon fiber pulling force is 830 tons. The actual acceleration of the asteroid is 6.5 meters. It is estimated that there are many ice blocks in it, and the weight is relatively low. .The immediate reaction acceleration of the aircraft is 70g. It is estimated that after 5 seconds, it will kiss the asteroid. Oh, this is not wonderful!"

But at this time, the intelligent program has actually activated the protection program engine to do vector motion, pushing the aircraft sideways for a certain distance.

Just suffered from two pilots.At this time, he was firmly hung on the chair by the seat belt, his hands and legs were stretched forward, and his eyes were protruding.And at this time, in order to resist this momentary pressure, he even used a life-saving secret method in practice, which can temporarily increase the strength of the body.

Swish... The plane quickly backed away from the asteroid, which was caused by the strong pulling force of the carbon fiber.

Then, once the force of the impact is exhausted, the shuttle is pulled back again by the carbon fiber.It's just that this time the power is much smaller.After decelerating through tens of thousands of meters of carbon fiber, it is already within the acceptable range.

After repeating this several times, he finally calmed down.The space shuttle and the asteroid are moving forward together at a speed of about 40 kilometers per second.

"Speed ​​up!" Lin Yun and Wang Sheng, who were still pale, were so scared that they almost killed themselves.The instantaneous 200g acceleration, fortunately, the time is short, and there is a secret protection.But even so, after going back, the two of them will probably rest for a week.And this week, you can't touch women, and you have to do your best to recuperate.

Pushing forward with all its strength, it was not until two days later that the space shuttle caught up with the spaceship whose speed had been reduced to 920 kilometers.When the alignment speed is zero, the spacecraft successfully captures the space shuttle and captures the asteroid.However, for Lin Yun and Wang Sheng's escape from death, everyone was more vigilant.Asteroids are not so easy to catch.

However, for the scientists here, the captured asteroid with a diameter of about 8 meters, to be precise, a meteorite mixed with a large amount of ice, is very precious.

Everyone started to dissect the asteroid by hand, and just hung it in space to start the work.However, the decomposed crushed ice can be used as a supplement for the spacecraft's water source.Use focused sunlight to sterilize and melt to save energy.

(The calculation of acceleration is messed up again... Khan)
