Annihilation of the solar system

Several people from the Near-Earth Object Observation Building ran and jumped to gather in front of the telescope main control computer in front of Wei Xu. The drive motor of the Near-Earth Object Telescope made a continuous "whining" sound, and the azimuth, pitch and focal length of the telescope were adjusted.

Adjust quickly within a small range.

When the drive motor stopped chirping, a photo appeared on the screen of the main control computer. With the completion of high-definition decoding, an almost perfect purple elongated ellipsoidal celestial body appeared on the display. Its color was brighter than on Earth.

The most precious natural amethysts are purer.

"Is this what Oumuamua looks like?" Liu Mengzhu sighed.

Wei Xu, who was sitting in front of the main control computer, looked at the automatic analysis data in the corner of the screen and said:

"No, definitely not. I think this is the high-temperature plasma flame emitted by the Oumuamua power unit. Due to the extremely high temperature, it appears purple in the visible light band. According to preliminary analysis of the observation program, the length of the plasma flame is more than 300 kilometers, and

The maximum diameter reaches 30 kilometers."

"Use the spectrum to analyze his temperature and visual magnitude!" Xia Lan said.

Wei Xu entered instructions on another screen of the computer, and the data was quickly displayed.

"It is estimated that the surface temperature of the plasma flame exceeds 60,000K, and the apparent magnitude is -15.2!"

Wei Xu's words surprised everyone. The surface temperature of the sun is only 5700K, and the temperature of the plasma flame in space is more than ten times higher than the surface temperature of the sun. And the star rating of -15.2 means that it is brighter than the full moon.

At that time, the apparent magnitude of the moon was -12.4, which was much brighter in the night sky.

Everyone left the main control computer and walked to the side of the huge near-Earth object telescope. Through the observation port opened in the hemispherical observation room, they looked at the starry sky in the direction pointed by the astronomical telescope. A dazzling new star was shining in the night sky.

It has a dazzling luster. It doesn't look purple at all to the naked eye, but is as bright and dazzling as the sun peeking out of the dark clouds.

The light from the new star painted the few floating clouds in the air dark silver, and the outline of the tree crown also appeared in the originally dark forest under the mountain. On the ground in the observation room, they could clearly see the light of the new star reflected on the ground.

The huge black shadow of the astronomical telescope appeared.

After a while, everyone's eyes felt a little stinging, because the brightness of the new star was too high in the night sky. The motor of the Near-Earth Object Telescope made an intermittently "whining" sound. This was the automatic tracking target.

The telescope is adjusting its orientation and angle.

"How far away is it from us now?" Xia Lan asked.

Wei Xu quickly returned to the main control computer.

"27 million kilometers!"

"So close!" Wu Fan exclaimed.

"Based on the current deceleration, Oumuamua will reach the vicinity of the Earth within 30 minutes!"

As the observation situation was urgently reported to EDA, the space telescope in low-Earth orbit immediately locked onto the rapidly approaching Oumuamua. Clearer photos and detailed data also appeared on the large screen of the Space Force Operations Department Command Center.

in the screen.

Chai Shizheng frowned and looked resolutely at the blue-purple oval plasma fireball on the screen. Its purple color was no longer as pure as when it was just observed, and its size and temperature had also dropped slightly.

"Can the lunar high-energy laser defense system launch an interception?" Chai Shizheng asked.

The staff officer beside him replied:

"Report General! It cannot be done at the moment! The reason is that although it is slowing down, its speed is still as high as 50,000 kilometers per second. The fire control system design of the lunar high-energy laser can only effectively lock targets below 300 kilometers per second."

Chai Shizheng asked again:

"Where is the space turret located?"

The staff officer replied:

"The space turret is currently located in a sun-synchronous orbit 2 million kilometers away. They are deployed near the intersection of the orbits of the spore swarm and the ice-breaking belt. The entry orbit of Oumuamua and the orbit of the spore swarm and the ice-breaking belt are 112

The angle is too far apart, and the fort cannot intercept Oumuamua."

Chai Shizheng's brows furrowed even more tightly. Although he looked serious, he was not blaming his staff. Because he knew that the lunar high-energy laser defense system and space fort were built around organic life on Europa and Titan.

. It really doesn’t have much effect on Oumuamua, which suddenly approaches Oumuamua at high speed.

However, eda received a gravitational wave signal from Oumuamua eight years ago near a white dwarf 4 light-years away due to the opening of a wormhole. While observing the white dwarf, traces of Oumuamua were also discovered through the crisis of interstellar dust clouds.

.At that time, the Space Force prepared a small-scale but highly targeted space interception plan.

The plan called "Dome Armor" actually enlarges the phased array radar and anti-aircraft missile silo on the destroyer and deploys it to low-Earth orbit, and replaces the missile warhead with a layer of alloy steel balls.

A 100,000-ton nuclear warhead is used as a working fluid. There are 6 sets of such systems in total, ensuring that there are no blind spots in any direction on the earth.

"Let the combat spacecraft and the 'Dome Armor' system in low-Earth orbit enter the first level of combat readiness." Chai Shizheng issued the order.

The next thing they have to do is to wait for Oumuamua to approach. Because the combat spacecraft armed with small spaceships and shuttles as well as the 'dome armor' system can take advantage of Oumuamua, which is still approaching at high speed 10 million kilometers away.

Mo has no choice.

The latest photos of Oumuamua, which are constantly refreshed in seconds on the command center, are changing at a speed visible to the naked eye. Its plasma fireball is gradually shrinking, and its color has changed from purple to blue. In the night sky, it

It has also changed from a dazzling new star to an ordinary star.

"The distance is 2 million kilometers, and it is expected to enter the interception range in ten minutes." The staff reported.

Chai Shizheng looked at Oumuamua, whose plasma fireball was only one-tenth of its original size on the big screen and turned yellow-white in color, and gave the order:

"The radar locks the target, the interceptor missile enters the standby state, and the combat spacecraft of the squadron with the best orbital position performs an emergency change to the synchronous orbit."

"yes!"

"Report! The radar has locked the target!"

On the real-time feed back image, the ellipsoidal plasma fireball gradually shrank into a nearly perfect circle, and its color also changed from yellow-white to orange-red. He now looks like a candle that has just been lit in the dark, but

The diameter of the 'candle' is still five or six kilometers, and it can no longer be found in the starry sky with the naked eye.

After another few minutes of silent waiting, the plasma fireball on the screen barely changed. If it weren't for the data constantly jumping in the corner of the screen, it would be easy to give people the illusion that the screen has not been updated in these few minutes.

"Report! The target has entered the combat radius of the interceptor missile!" the staff officer said loudly.

Chai Shizheng ordered almost without thinking:

"Launch three interceptor missiles!"

The officer on the console immediately flipped three switches in accordance with the order, and then pressed the red launch button.
