On the 13th, in the evening local time in China, Apophis was visible from space with the naked eye.
After all the space shuttles underwent final inspections, they began to accelerate; this time, because there were too many novices, remote computer control had to be the main method, supplemented by close-range manual monitoring.
At this time, all space shuttles are already waiting millions of kilometers away from the earth, which is almost three months from the moon to the earth.
Operating at such a distance not only ensures that the earth is nearly 100% safe, but also provides enough space for operations. The only problem: exposure to space without the protection of a magnetic field. Fortunately, the technology of Gaoshou Company has solved this problem. But this magnetic field has not been truly tested after all.
Live broadcast all over the world, such an action is too dazzling to hide. At this time, even the country that hates China the most in the world has to take a hard look to see if it has the qualifications to hate China. To be honest, there are more than 1,200 space shuttles and several strange-shaped objects (modules of the Adventure spacecraft), which make many people wonder whether there is more to China's real power!
"Adjust the center position."
The computer made crazy calculations and locked the most ideal interception position of the asteroid.
The space shuttle began to accelerate, following the direction of the asteroid, accelerating toward the Earth. According to calculations, theoretically, synchronous speed can be reached within about 150,000 kilometers.
But this is just theory. Because the asteroid itself is still turning over...
In the space shuttle, Yang Zhi sat quietly, watching all the data closely. This operation will take more than three consecutive days; before the fiber net is tied to the asteroid, there is no rest. Even if you want to pee, you have to hold it in; if you can't hold it in, you pee in your crotch.
In fact (don't laugh), when the space suit was designed, this problem was considered, and excretion can be completed directly in the space suit.
Feeling the roar of the engine, Yang Zhi felt a kind of tension that he couldn't control. Everything is controlled remotely; in fact, over a distance of 1 million kilometers, the communication speed is only 250,000 kilometers per second (interferenced by magnetic fields, space, etc., less than the speed of light of 300,000 kilometers), which is a delay of 4 seconds.
In fact, if there is any change here, the space base will not receive the signal until four seconds later; then it has to react, calculate and give instructions, even if the computer only has 0.03 seconds of calculation time, after the signal returns , also 8 seconds later. And in this rapid sky, for 8 seconds, the space shuttle did not know where to go.
Therefore, today, when communication technology is still imperfect, humans still need to operate the space shuttle. Otherwise, if something really happened to the space shuttle, the space station would only know it after 4 seconds; and by this time, more space shuttles might have crashed!
Therefore, the pilot needs to keep his hands on the control panel as much as possible. Once an accident occurs, he must switch to manual as soon as possible and notify all other space shuttles.
"We have seen an asteroid, everyone, be prepared." In space, each echelon has a captain who is responsible for overall adjustments, and the person in charge of these new students in the master company is Liu Haibo. Mu Xinghai is responsible for the overall dispatch at the space base, and Liu Haibo is the only one who can restrain these recruits.
In fact, there is no need for Liu Haibo to emphasize that Yang Zhi has also seen Apophis. Although the two sides are still 150,000 kilometers apart, there is no obstruction by the atmosphere. With the help of scientific instruments, it can be seen with the naked eye. In space, Apophis's current brightness is almost equivalent to magnitude 6, and it is easy to miss it if you are not careful.
(Due to the large data header, the following data are not calculated, please understand)
The somewhat boring voices of scientists came from the headset; this made it difficult for Yang Zhi, who was used to hearing the beautiful female voices of the expert company, to adapt. However, I also know that this is the most direct order from the space base at the moment, and there is no way to optimize it. You know, in order to dub, Gaoshou Company searches for voice actors all over the country and hires them with a lot of money to dub for all the space shuttles and space projects of Gaoshou Company; and they can produce dozens of high-quality dubbings at one time. It is said that it is still increasing.
"The flight formation speed is 5 kilometers, and the two sides are 120,000 kilometers apart. The temporary speeds are the same. The center positions are the same.
Please keep the existing acceleration and direction unchanged. ”
"Please note, please note that Apophis has passed the peak of its orbit and is in a state of decline; now there is a weak acceleration trend. But don't panic, this is already being calculated."
"The current flight formation speed is 7 kilometers, the two sides are 95,000 kilometers apart, and are falling towards the earth.
Please be prepared. According to this direction, Apophis will pass by at an altitude of 29,000 meters above the earth, and one-seventieth of it will fall into the gravity keyhole according to new calculations. We have to intercept. ”
"The flight formation speed is 30 kilometers, and Apophis is already next to us. Please note, please note that Apophis' orbit is not straight, but has a slight arc. Apophis is now on the way home; This guy is eager to get home and the pace is increasing.”
"The flight formation speed is 46 kilometers, oh yes, we have surpassed Apophis. Now the time to test us has arrived. Comrades, work hard, a glorious tomorrow is waiting for us.
Now listen to the order, the third echelon accelerates, intercepts in front of Apophis, and then maintains the same speed as Apophis without contacting Apophis. ”
In the space base, everyone was sweating with their palms. This was a rapid space operation. Not to mention big mistakes, even if there was a 0.001 parsec difference in the calculation, catastrophic changes would occur.
In 0.001 seconds, Apophis can fly 45 meters!
Equally nervous were the members of the third echelon; the third echelon were all space shuttles belonging to the Master Company, and they were towing a 30,000-meter-long carbon fiber mesh. In addition, the space shuttles of Gaoshou Company have different qualities and thrusts, and they have to drag a huge net with a diameter of more than 60,000 meters, which is the most difficult part of the entire operation. But because the aircraft of the Master Company have high thrust, it is also the most important part.
The pilot sitting in the plane was even more nervous, but now that everything was controlled remotely, he could only nervously monitor the various instruments and displays of the plane.
Through the porthole, you can see Apophis very close at hand. This is the first time Yang Zhi has observed an asteroid up close - the distance between the two is only 100,000 meters, 100 kilometers away! After practicing, I didn’t even need a telescope. I could see that the top was full of bumpy impact craters. The smallest ones were probably only about the size of a wine glass, but they couldn’t be seen clearly. The largest ones were several meters. The meteorite is overall grayish white and slightly black; the structure and texture of the composition cannot be seen with the naked eye. Such an asteroid has a diameter of nearly 400 meters and an irregular oval shape hanging in space. It is really shocking to see it from this distance. Of course, what was even more shocking was that Gao Shou Company and Hua Xia had come up with such a crazy plan.
"The third echelon is ready, the second echelon is ready..."
"The second echelon is ready, the first echelon is ready..."
All carbon fiber meshes have been stacked together to form an airtight carbon fiber "wall" with a diameter of 500 meters. The center position is meticulous, and it is more than 10,000 meters away from the center of the asteroid.
"The reserve team is ready to protect the No. 1 cabin of the Adventure spacecraft and start the magnetic field generating device. Set up the net and wait." "Okay, now the reserve team is close to the flight group."
