The asteroid's position is not directly in front of the route, but diagonally opposite. The vertical distance from the spacecraft route is approximately 30,000 kilometers. This distance, in space, is really very close.
"Scan distance. Calculate time." The new Dream space shuttle already comes with a complete voice recognition system. Ten minutes have passed since the asteroid was scanned, and it must be scanned.
"The scan is completed. The asteroid is now 580,000 kilometers behind the spacecraft, and its speed relative to the spacecraft is negative 966.25 kilometers.
To capture the asteroid, you need to slow down first. Note that because you are following the spaceship, you now have an initial velocity of 1000 kilometers per second. Then it drags an asteroid with a mass of up to 3100 tons to accelerate to catch up with the spacecraft. By calculation, you don't carry enough power.
After comprehensive computer analysis, unless you want to die, don't capture that bastard.
You should now shut down the engines and follow the spaceship forward. ”
Pfft... Lin Yun burst into laughter, "This is some kind of smart program created by the technology department!"
"Captain, it's a semi-intelligent program." A hint of embarrassment flashed across Wang Sheng's face next to him: In fact, he just set up the program because his hands were itchy!
"Okay, I have no choice but to give up. Report to the general control that Plane 301 cancels the plan to capture the asteroid; however, it will not return to the spacecraft for the time being and will circle around the spacecraft."
"General control received. Please pay attention to safety and try not to leave the magnetic field protective 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 Will speed up. Please control your speed.”
"Thank you." Lin Yun switched the communication to Zhang Jianye: "Scientist Zhang, I'm sorry, we are moving too slowly. The asteroid is already 580,000 kilometers behind us. It is no longer valuable to capture."
"Oh, it doesn't matter. I was negligent. Just so I heard from the main console that you are not ready to return for the time being, so just stay in space for a while. Well, another asteroid was discovered. It is 190,000 kilometers in front of the spacecraft. ”
"Okay, I'll try my best." Lin Yun could only try to capture this asteroid.
"Automatic scanning."
"Didi... the scan is completed. The asteroid in front has a maximum diameter of 9 meters and a minimum diameter of 7 meters. Spectral analysis shows that it is mainly composed of three elements: silicon, oxygen and iron. It weighs about 1,300 tons and has a speed of 35 kilometers per second.
The vertical distance from the spacecraft orbit is 40,000 kilometers, and the closest time is estimated to be 190 seconds later.
Calculated based on the aircraft's 500-meter acceleration, it takes 179 seconds to cross 40,000 kilometers. Theoretically, the time is enough for operation. But it must start now. ”
"Start, 50 times the acceleration of gravity!" Lin Yun started immediately without hesitation. There are many asteroids in space, but there are very few that are exactly in the direction of the spacecraft.
"Beep...the computer is calculating safety. The current speed of the aircraft is 1,000 kilometers, and after 178 seconds of lateral acceleration, the estimated speed is 1,004 kilometers per second. The asteroid speed is only 35 kilometers per second.
To complete the plan to capture an asteroid, 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 intelligent program looks like this, which really makes people feel like Alexander.
Wang Sheng next to him has his head lowered. Is it because his itchy hands are set to cold humor mode? Is that so? I never thought that cold humor would be such a way.
However, although the calculated answer is rather strange, it must be said that this is indeed an act of committing suicide.
The speed difference between the two is so large that even if it is reduced through the carbon fiber mesh, it will eventually cause great harm to the space shuttle.
Fortunately, after the last capture of the asteroid Apophis, the carbon fiber net drag technology has been improved, and that is the use of elastic technology. In order to meet safety requirements, the carbon fiber mesh can be pulled up to a distance of 100,000 meters, and the high-strength nanocarbon fiber is enough to drive a pulling force of nearly a thousand tons, which is enough to be used as a high-end space material.
Of course, the speed difference between the two is quite large, so doing so is still dangerous. If the pulling force is greater than 1,000 tons, the space shuttle will automatically activate the safety device and eject the carbon fiber device away from the aircraft.
The 50 times acceleration of gravity made Lin Yun, who was only at the seventh level of Qi training, and Wang Sheng, who was only at the sixth level, feel like they were on the verge of death. This feeling is really terrible, as if my own weight is crushing my chest and my heart is tightly attached to my back.
Inside the aircraft cabin, the engine rumbled.
With an indomitable momentum, the plane began to accelerate violently in the direction perpendicular to the spacecraft.
In space, a space shuttle moves laterally at a speed of 1,000 kilometers per second and accelerates vertically at an acceleration of 500 meters!
In fact, the plane's real sailing direction is diagonally.
"We are getting closer. We need to slow down, otherwise we will miss it. The engine needs to be shut down!" Wang Sheng was helping.
"The distance is 3,000 meters. We will pass by 100 meters above the asteroid. The time is only one thousandth of a second. Start the automatic capture system."
"Beep... bump!" Amidst the huge sound, a gray nano-carbon fiber network popped up, accurately covering the entire asteroid.
At this time, the space shuttle quickly passed over the surface of the asteroid and was about to fly away with a bang.
The carbon fiber tightened instantly, and slender carbon fibers continued to extend from the butt of the aircraft. In an instant, a reaction force of up to 800 tons acts on the aircraft. It made the plane creak.
The computer automatically reports "real-time 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 expected that there are a lot of ice blocks in it, and the weight is low. . The aircraft’s immediate response acceleration is 70g. It is expected to kiss the asteroid in 5 seconds. ”
However, at this time, the intelligent program has actually started the protection program and the engine performs vector movements to push the aircraft sideways for a certain distance.
It's just a pain for two pilots. At this time, he was hung firmly on the chair by the seat belt, his hands and legs were stretched forward, and his eyes were bulging outward. At this time, in order to resist the pressure of this moment, he used a life-saving secret method in spiritual practice, which can temporarily increase the strength of the body.
Swish...the plane quickly retreated from the asteroid, which was caused by the strong pulling force of the carbon fiber.
Then, when the impact force was exhausted, the space shuttle was pulled back by the carbon fiber again. But this time the power was much smaller. After tens of thousands of meters of carbon fiber deceleration, it is already within the tolerable range.
After repeating this several times, he finally calmed down. The space shuttle and asteroid are moving forward together at a speed of about 40 kilometers per second.
"Speed up!" Lin Yun and Wang Sheng, whose faces were still a little pale, looked frightened and almost died. The instant acceleration of 200g was fortunately short-lived and protected by a secret method. But even so, the two of them will probably have to rest for a week after returning. And this week, you can't touch women, and you have to do your best to take care of yourself.
Pushing forward with all its strength, it was not until two days later that the space shuttle caught up with the spacecraft, which had slowed down to 920 kilometers. When the line-to-line velocity is zero, the spacecraft successfully captures the space shuttle and captures the asteroid. However, Lin Yun and Wang Sheng's narrow escape from death made everyone more vigilant. Asteroids are not so easy to capture.
But for scientists here, the captured asteroid with a diameter of about 8 meters, or to be precise, a meteorite mixed with a large amount of ice, is very precious.
Everyone began to dissect the asteroid, and the work began while it was suspended in space. However, the decomposed ice can be used as a supplement to the water source of the spacecraft. Use focused sunlight to disinfect and melt to save energy. (The acceleration calculation is messed up again...sweat)
