Under Zhao Changxing's order, a space sweep operation with the greatest power that human civilization can muster at this stage was immediately launched.
A total of 22 Wu-1 combat spacecraft and 30 Flame-1 transport spacecraft have undertaken this task.
Originally, there were only 10 Wu-1 combat spacecraft, but now there are 22.
In addition to the spacecraft, there are hundreds of land-based and space-based deep space radars participating in this mission. With the most stringent attitude, people scanned all the spaces around the Sedna star inch by inch, trying to connect all the space.
Not a particle of space dust is missed.
Under this kind of search, within a month, people found four space objects that clearly did not belong to human civilization. These were obviously spy satellites of deep space civilization.
Of these four spy satellites, three successfully self-destructed during the capture process, and the last one had its electronic system directly paralyzed by an electromagnetic pulse bomb, so it was considered intact.
It's just that what people got was only the "corpse" of the spy satellite, but no "soul". Because all the electronic components inside it had been burned and all the data had been lost.
People can be sure that unless deep space civilization adopts technology that is generationally different from the current stage of human civilization, there will definitely no longer be technological creations of non-human civilization within a range of 100,000 kilometers around Sedna.
Under such circumstances, the renovation operation of Space Elevator No. 1 finally began.
Part of the counterweight at the end of Space Elevator No. 1 was temporarily removed to reduce its own weight, reduce the pressure on the space elevator cable, and prevent it from breaking beyond its limit. After that, part of the material of Space Elevator No. 2 was attached.
The diameter of the cable of Space Elevator No. 1 is as high as one meter, but it was not like this at the beginning. At the beginning, people just pulled a cable with a diameter of only 0.5 mm, and then continued to increase the cable on top of this cable, and finally
Only then did it expand its diameter to one meter, giving it super tensile strength.
The same is true for the project being carried out at this moment. The first connected space elevator cable is also only 0.5 mm in diameter. A cable of this specification, even if it is 5,000 kilometers long, has a volume of less than 100 cubic meters and a low quality.
If it exceeds 200 tons, it only needs to be transported a few times by the Flame 1 spacecraft to transport it up.
At the end of this first cable, people added a counterweight weighing 300 tons, so the cable was stretched straight. On the basis of this cable, people added subsequent cables to make it straight.
The diameter expanded to about 35 cm.
A cable of only 35 centimeters is enough to pull a mass of up to 10,000 tons, making it impossible for it to break free.
At this moment, the total length of the space elevator has reached the predetermined level. The terminal linear speed has also reached 1.83 kilometers per second.
The launch platform components that have been prefabricated in advance were transported here, and assembly operations began here.
Because the linear velocity is too high, there is even considerable gravity here - about four times the gravity of Sedna. However, the direction of gravity is opposite to that of Sedna. One points to the center of the earth and the other points to space.
This environment is very suitable for assembly operations. You don't have to worry about parts flying around in a zero-gravity environment, nor do you have to worry about parts being too heavy due to high gravity.
In just half a month, the launch platform with a total mass of about 2,000 tons was completed. After that, a large amount of liquid oxygen and methane fuel began to be transported by the Flame 1 spacecraft, and the five rockets used to carry out this revenge mission
The casing of an interstellar missile was also transported.
All the assembly work took about another month. At this moment, all the work has been completed.
In the War Readiness and Defense Room of the Human Government of Sun City, under the watchful eyes of several war committee members, Zhao Changxing typed a series of characters quickly with both hands on the keyboard: "Dear Deep Space Civilization, regarding the two sides you proposed before
Regarding the matters related to the mutual dispatch of diplomatic envoys, we believe after careful consideration that for the long-term friendship between our two civilizations, in order to promote mutual understanding and mutual trust, and for the subsequent cooperation in economy, trade, science and technology, industry, resources and other aspects, we believe that,
It is very necessary to send envoys to each other. We are selecting suitable candidates and sincerely welcome the arrival of your envoys. I wish the friendship between our two civilizations will last forever and remain unchanged."
Simply pressing the send button, the message was transmitted to the Fire spacecraft, and then entered space at the speed of light through the antenna on the Fire spacecraft, flying towards the deep space more than 60 million kilometers away.
star.
After finishing the matter, Zhao Changxing looked at the committee members.
"Have all the relevant work been done? Okay, then, let's launch."
"yes!"
Following Zhao Changxing's order, the countdown began immediately.
When the countdown returned to zero, the launch platform moved to a suitable position. Then, at the end of the space elevator, in the space 10,000 kilometers away from the surface of Sedna, 100 launchers with a fixed total mass of up to 10,000 tons
The platform's cables were disconnected at the same time.
Without the traction of the space elevator cable, the launch platform was immediately "thrown" out.
Its speed of motion has not changed at all, but its orbit has changed from circling before to "flying" along the tangent of the orbit. The gravity inside it disappeared immediately, but because people had already made preparations in advance,
This had no internal impact.
At this moment, without consuming any fuel, the launch platform with a total mass of 10,000 tons has acquired an initial speed of 1.83 kilometers per second out of thin air.
After it was thrown out, ten specially modified Flame 1 transport ships filled with fuel were also thrown out, slightly offset from the launch platform, and followed it.
The next moment, ten transport spacecraft and the launch platform began to accelerate at the same time.
A dazzling bright fire appeared in the vast and deep universe. Driven by the high-speed gas generated by the burning of huge amounts of fuel, the powerful reverse thrust began to push the launch platform and the transport spacecraft together to accelerate.
When the acceleration action only lasted for more than ten seconds, the first Flame Type 1 transport ship had already caught up with it. Both sides maintained the same acceleration rate and the same direction of acceleration. Both sides were relatively stationary.
Under this situation, the ten fuels that had been standardized and packaged on the spacecraft were transferred to the launch platform and placed into the automatic feeding device by the staff.
The spaceship flew away immediately. Soon followed by the second, third, and fourth ship...
It was not until all ten spacecrafts completed the fuel transfer that the astronauts who were performing tasks on the launch platform quickly transferred to this spacecraft at great risk. The spacecraft then slowed down and began to return to Sedna.
At this moment, the speed of the launch platform has increased to 6.2 kilometers per second, and is still accelerating. Under this situation, there is no returnable human creation that can catch up with it.
People have replenished part of the fuel for it through this "unconventional" means.
In the combat readiness and defense room, Zhao Changxing and others were nervously watching the acceleration process of the launch platform through the monitoring screen.
Time slipped away bit by bit. When the speed of the launch platform accelerated to 10.83 kilometers per second, the nearly 10,000 tons of fuel on the launch platform had been consumed. They were all turned into gas and ejected in the violent combustion.
.
"Launch platform detached."
"Yes! The launch platform is detached!"
In the main control room, the on-site commander pressed a button nervously. The next moment, with a controlled micro-explosion, five interstellar missiles broke away from the launch platform.
In a gravity-free environment, without reference objects, they seem to be standing still at speeds of up to 10.83 kilometers per second.
Both sides are moving in the same direction and at the same speed.
"Missile ignition."
"Yes! Missile ignition."
The next moment, the five interstellar missiles that were dispersed in the controlled explosion ejected bright fire from their tails, pushing them to accelerate again.
The launch platform was immediately left behind.
Ten minutes after ignition, the third-stage fuel of the three-stage interstellar missile was exhausted, and the speed increased to 19.25 kilometers per second.
"Throw the third level."
"Yes! Throw the third level."
The third-stage missile body immediately detached.
"Enter inertial navigation state."
The first and second stage projectiles will not ignite for the time being. They will not ignite until they are close enough to the deep space star after a long voyage.
The inertial navigation will last for more than a month.
During this period, the steering engine equipped on the missile body will perform several short-term ignitions to apply some steering power to these missiles, causing them to slightly deviate from the fixed orbit. This is mainly to prevent the orbit from
It is too fixed and too easy to be predicted by the enemy.
More than a month has passed by very quickly. Now we have entered the end of the voyage.
"Second stage ignition!"
The five interstellar missiles, which had been shortened by half in length compared to the original ones, once again ejected fire from their tails, pushing them to speed up again.
"Throw the second level!"
At this moment, their speed has increased to 27 kilometers per second.
The total speed that the entire first level can increase is only 2.83 kilometers per second. But its status is the most important.
It will not ignite again until the missile enters the vicinity of the planetary defense system of the Deep Space Star. The main purpose of doing this is to reduce the probability of being intercepted by accelerating the missile again.
This range was set by Zhao Changxing as 150,000 kilometers.
"Reporting to the leader, the missile will enter the range of the Deep Space Planetary Defense System in five minutes!"
