Annihilation of the solar system

Director Yin saw the change in expression on the engineer's face.

"What's going on? Is it difficult to operate?" he asked.

The engineer lowered his head, not daring to look at Director Yin's sharp gaze.

"Well... it's theoretically possible. But our satellite laser calibration program is written based on a distance of three million kilometers. If you want to change the parameters of the calibration program, it's not impossible. But... but it requires a program

Only software experts from the control department can make changes. This has happened before and it took several days..."

The engineer finished speaking hesitantly and looked up at the countdown sign that kept beating every moment.

Director Yin took a deep breath and swept his eyes like sharp knives over the engineers who lowered their heads and did not dare to look at him. Finally, without saying anything, he slowly exhaled and then took off his clothes.

The jacket looked exactly like the uniform of the space center. In fact, the stitching and inner material were much more refined. He handed it to the engineer.

"Call Team Leader Zhao and Team Leader Zhou to come over and switch the satellite to manual control mode." Director Yin said to the engineer while walking towards the console in the front row.

The engineer took Director Yin's coat and was stunned for a moment, with an incredible look in his eyes. Then he hurried to carry out Director Yin's instructions.

Director Yin walked to the console closest to the big screen. The biggest difference between this console and other consoles was that it had two aircraft joystick-like grips. He pressed the various switches on the console familiarly.

and knobs. At this time, two middle-aged people, a man and a woman, were doing the same operation on the same consoles on the left and right sides.

"You two haven't forgotten your housekeeping skills, right?"

Director Yin continued to adjust the switches without looking up at them.

"Don't worry, Director Yin. When I was a control engineer in the past, I didn't have such a complete automatic control system now. I have practiced so well that I will never forget it in my life." said the middle-aged man next to him.

Director Yin nodded with satisfaction and said in a relaxed tone as if discussing hot news while eating in the cafeteria:

"Don't be nervous, we will succeed the first time."

After saying that, Director Yin slowly stretched his hands towards the two joysticks and held them firmly. He raised his head and glanced at the string of blood-red numbers. He knew that the remaining time allowed them to succeed only once.

Xia Lan and Wei Xu were also at the Capital Observatory on the outskirts of Beijing at this time. They were observing one of the satellites through a huge hemispherical near-Earth object telescope. Originally, this kind of artificial satellite did not require ground telescopes for tracking and observation.

What's more, astronomical phenomena like gravitational waves cannot be detected at all in the visible light band.

However, the three satellites all work at extreme distances and extreme conditions. If something goes wrong, it is possible to know what happened in the shortest possible time. There are three observatories around the world tracking these three satellites with near-Earth object telescopes, and Xia Lan

The Capital Observatory where they were located was tracking the one that Director Yin manually controlled.

This task actually does not need to be completed by scientific researchers like Xia Lan and Wei Xu, but this observation mission is too important to them. At Xia Lan's strong request, she came to the huge telescope to witness it with her own eyes.

A historic moment.

Xia Lan saw through the telescope that in the space where the air can be easily frozen into a liquid state, the Taiji satellite's attitude adjustment nozzle emitted thin white gas from time to time. Under the guidance of radio waves that came every ten seconds, it

It changes its position slightly. At this time, even if you use bright stars or colorful planets as reference objects, it is difficult to see whether it is really moving.

Compared with the Taiji satellite, those reference objects are really too big. But there is no other object in the vast space that can be used as a comparison. Even the nearest Taichi satellite cannot be seen at all.

Those radio waves modulated into 0s and 1s accurately command the timing and duration of opening of each attitude-adjusting nozzle. The source of those signals is exactly the one in the hands of Director Yin on the operation platform of the aerospace control center.

The two joysticks are small but delicate in every movement.

The red light emitted by the countdown numbers above the big screen seemed to be stronger, reflected in the eyes of everyone in the control center, and also reflected on the glass curtain wall of the conference room on the second floor. Although the electronic countdown was always silent

Running quickly without making any sound. But as the numbers gradually decreased, the lingering "tick" sound seemed to be lingering in everyone's ears.

Team Leaders Zhou and Zhao on both sides of Director Yin, like the engineers, had their shirts sticking to their backs due to sweat. Director Yin's gray eyebrows were also filled with sweat beads. But they all had calm expressions and breathed calmly.

. His eyes calmly looked at the dancing numbers on the big screen, and the hands holding the joystick moved delicately like carvings on the tips of knives.

Everyone at the scene carefully controlled their breathing, fearing that any noise would affect the posture of satellites millions of kilometers away. There were only a few red numbers left, and everyone's heart was in their throats.

Some staff members who were less able to bear it covered their cheeks with their hands, while others turned their backs to the flashing red countdown.

The countdown on the screen marked the numbers corresponding to hours and minutes have changed to "00", leaving only the numbers corresponding to seconds and milliseconds still beating.

Finally, when the seconds turned into single digits, the words "Calibration successful!" appeared on the big screen!

The scene immediately burst into thunderous applause!

Director Yin was relieved. He looked back at Xia Jigang and Minister Zhong who were standing behind the glass curtain wall on the second floor, and waved to them. Xia Jigang and Minister Zhong also had smiles on their faces and nodded to him frequently.

The countdown has all returned to 0. This means that if Liu Chaowen's prediction of gravitational waves comes true, then a picometer-level gravitational wave will erupt from each of them by distorting the ripples of space and time in a thousandth of a second just now.

It passes through people's side and body. However, gravitational waves of this scale cannot be sensed.

However, the tiny displacements of the three satellites caused by it can be detected by the laser interference receiving target.

After more than ten seconds of communication time, they will know the preliminary results.

Director Yin confidently took the clothes from the engineer who helped him get his coat and was about to put them on when a flashing red triangle warning sign suddenly popped up on the screen.

Below the flashing logo is a line of equally eye-catching red fonts:

"Signal abnormality, error code 0753! Attitude abnormality, error code 0194"

The former error code means that the Samsung array has been destroyed due to the position change of a satellite. The latter error code means that there is an abnormality in the orbit and attitude of a satellite. Both codes refer to the same satellite.

It's the one that Director Yin manually controls.
