Hara and Durunik walked into the control center. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The control center is constantly sending out various operation instructions and receiving relevant feedback.

"The pupil of the earth has entered the predetermined orbit and started the equipment self-test."

"The laser emitter is fully charged, and the device self-test is initiated."

"The two sets of light sail simulations of the Earth Pupil have been successfully completed."

"The linkage system between the pupil of the earth and the laser emitter is running smoothly."

......

"Guys, are you all ready?" Yuan Haochen asked with a serious expression.

"The preparations have been completed. Just wait to enter the predetermined launch orbit. The operators of each position replied.

"Okay, let the computer system do another simulation and complete the self-test to make sure nothing goes wrong." Yuan Haochen continued to explain.

"Listen to your command!"

The giant screen in the center of the command hall is displaying the real-time transmission of images from the space station and the pupil of the earth.

Yuan Haochen stared intently at the screen, and the other high-level officials of the base were also sitting in their positions without saying a word, quietly waiting for the critical moment to come.

The clock was ticking, and the giant screen was counting down the launch time.

The computer system has calculated the angle and direction of acceleration for the Pupil of Earth in advance to ensure that it can follow the most accurate flight path to the Centaur Alpha system.

As the saying goes, a good start is half the battle, and this is even more important to the pupil of the earth.

If its initial flight path deviates too much, it will be difficult to use the lightsail's fine-tuning function to correct its flight path throughout the flight, resulting in never reaching the Centaur Alpha system.

In addition, every mutual collision with particles in the universe throughout the flight will cause a slight change in the direction of the flight.

Although theoretically, the probability of an impact coming from either direction is equal, so over time, the true direction of flight of the spacecraft will infinitely approximate the design direction of flight.

Although in this ideal state, the impact of particles does not change the direction of the spacecraft obviously, if these subtle effects are left unattended, there is a possibility that the small impact will be missed by a fraction of a second, after all, the journey of 4.2 light years is too long to ensure that there will be some forks in the road.

"The first set of light sails of the Pupil of the Earth has been unfurled."

The operator began to broadcast the launch process in an orderly manner.

"The laser emitter is ready, and the countdown to launch begins."

"10,9,8,7,6....1, start!"

Suddenly, there was a high-frequency tremor in the video footage transmitted from the space station.

Because the sound of cosmic space cannot be transmitted, the picture is silent, but looking at this scene in front of me, it still makes people feel a sense of tightness in the scalp.

Yuan Haochen knew that the laser emitter had been activated.

If you stand in the distant space of the universe at this time, you can clearly see that an incomparably powerful and intensely bright pure light burst out of the laser emitter and accurately illuminated the light sail of the Earth Pupil.

The moment it received the high-energy laser beam, the pupil of the earth seemed to turn into a dazzling light, and it disappeared from the spot in an instant, flying to the distant horizon.

According to the plan, the powerful laser beam will quickly accelerate the pupil of the earth to its maximum speed in a few tens of minutes.

"The Pupil of the Earth is flying normally, the light sail is working smoothly, and it is continuing to accelerate.!"

The command center transmitted the results of the staff's detection of the flight status of the Earth Pupil, and the latest data was constantly updated on the large central screen.

"Whew~"

Yuan Haochen finally let out a long breath in his heart.

Because in the last second, a sentence was still floating in Yuan Haochen's head--"Between talking and laughing, the tree is in ashes!" ”

After all, it was a laser beam with such a powerful energy shining on the lightsail.

Although the lightsail has been designed to have a reflectivity of 99.999999% (there is no 100% reflective mirror in the world), which means that 1 in 100 million light will still be absorbed by the lightsail, and 1 in 100 million sounds small, but for such a powerful laser beam, the energy contained in it is indeed huge.

If it were replaced by the nano spacecraft in Old Man Hawking's "Breakthrough Star" plan, it would have been heated to more than tens of thousands of degrees, and finally the canopy would have disappeared!

Although the launch team has done a tolerance test of laser beam irradiation to the light sail before, but when it comes to the moment of launch, everyone's experience is naturally completely different.

Obviously, even the few bigwigs who were supervising the formation in the command center instantly became much more comfortable after hearing the news that it was running normally.

"The Earth Pupil is flying normally and is continuing to accelerate, currently at 10.2% of the speed of light."

It seems that with the help of alien super technology, the most difficult light source technology of laser sails has been solved, and the acceleration process of the Earth Pupil is far smoother than that of Hawking's nano-flying machine.

"The Earth Pupil is flying normally and is continuing to accelerate, currently at 30.4% of the speed of light."

Five minutes passed, and Yuan Haochen, like everyone else, was engrossed in the data that kept beating on the screen.

"The Earth Pupil is flying normally and is continuing to accelerate, currently at 55.2% of the speed of light."

"The Earth's pupil is continuing to accelerate, currently at 65.3% of the speed of light." Fifteen minutes passed, and the acceleration of the Earth Pupil began to slow down significantly.

"According to the plan, the upper limit of the energy of the current laser emitter is 25~27 minutes." Yuan Haochen frowned, and began to calculate quickly in his heart.

All the staff in the command center, the spirits that had just been soothed, tensed up again.

According to the theory of relativity, an object can be approached but cannot reach the speed of light.

The greater the velocity of the Earth Pupil, the greater its mass. So, the later you go, the more difficult it becomes to accelerate.

"It is continuing to accelerate, and it is currently at 73.6% of the speed of light." Twenty minutes passed, and the acceleration of the Earth Pupil was much more difficult than expected.

"The Earth's pupil is currently traveling at 82.1% of the speed of light. The laser emitter will stop working after 2 two minutes. ”

At this last moment, in addition to the heavy breathing of everyone, the entire command hall could only hear the sound of various instruments running.

"The laser emitter has stopped working, and the Earth Pupil is finally emitting at 84.91% of the speed of light."
