Annihilation of the solar system

Just when Ke Guohao was about to set off, the technical officer delivered bad news:

"There are several leaks in the sealed compartment of the hull, one of which is near the equipment compartment. I can't pressurize the section near the equipment compartment. You can't get there without a space suit."

This was not a big problem at first. Before the battle started, everyone was wearing space suits and life cycle backpacks. But just now in order to start the sonic voice AI program, everyone vented the air in their life cycle backpacks to pressurize the bridge.

At this time, the captain turned his attention to the fleet commander who was still motionless on the porthole glass and had not spoken for a long time. Although everyone was unwilling to accept it, the fleet commander in his sixties could not withstand the huge overload before deceleration, and

The life cycle backpack on him has not been released yet.

Ke Guohao put on the life cycle backpack left by the fleet commander and left the bridge. After the sealed cabin below completed the decompression, he began to move hard towards the equipment cabin located in the middle of the hull. The initial operation was very difficult, with an overload of 2g

Make every step he takes look like he's doing a pull-up.

Just when his physical strength gradually became unable to support him, it gradually became easier to move forward. After a certain distance, he could even barely walk upright. This is because the space turret rotates along the short axis of the centerline of the hull.

, the closer to the middle of the hull, the smaller the centrifugal acceleration.

When Ke Guohao came to the equipment room, the comfortable feeling of weightlessness returned. But because the ship was still spinning, he had to carefully hold on to things around it to avoid being hit. He skillfully found the two groups

lines, and swapped their line order.

"Bridge, I'm Ke Guohao. You can try pumping fuel." After Ke Guohao finished his report, he let out a sigh of relief, then curled up under the cabinet and took out a picture with Li Linjie and Ye Wanqing during the trial training at the space center.

A group photo. He recalled the hard and wonderful times in the past, with a smile on his lips.

Soon, the cabinet behind him gave him a little pressure, and he knew that the deceleration was successful. After stopping the spin, the captain led everyone to immediately start repairing leaks in the sealed cabin and counting casualties. More than 2/3 of the crew were there.

They lost their lives in the rollover and overload spin, and none of the injured survived until the spin stopped.

Later, the captain summoned the surviving crew members to the bridge. Although the space turret stopped rotating and solved the most urgent problem at the moment, they were still flying out of the solar system at the third cosmic speed in space.

"In the process of encountering the alien spore biological rocket engine and avoiding collision, we consumed a lot of fuel. Now there is only 10% of the fuel reserve left in the fuel tank of the orbiting engine, which cannot allow us to complete the deceleration and

Return. According to the current orbit, we will not encounter a celestial body that allows us to use a gravitational slingshot to return before the supplies are exhausted.

This is the situation we are facing now. If we can't find a way to get us back to Earth's orbit, we will stay in space forever after the supplies are exhausted. I don't want to hide anything from everyone, we have all completed the task brilliantly. If this

This is our ending. At least we can say goodbye to our comrades and face our fate calmly." The captain's calm narration shocked everyone's hearts.

There was silence in the bridge for a long time, and the technical officer in charge of fire control suddenly shouted excitedly.

"We can use it! Use Newton's third law!"

He excitedly pointed to the three huge electromagnetic railguns outside the bridge window.

Everyone immediately understood what he meant. When firing, the reason why the positioning engine needs to work continuously to keep the space turret in place is because the reaction force generated when the rail gun is fired will push the turret away from its original position.

Sir Isaac Newton told people more than 300 years ago that two interacting particles are equal in size and opposite in direction, and are on the same straight line. The direction of the force generated when the electromagnetic gun shoots is the direction of the projectile.

On the contrary, the force is equal to the kinetic energy of the fired cannonball. This law discovered more than 300 years ago has now become the guideline to save them.

But before the people on the bridge could get happy, the staff officer came to a depressing conclusion on the computer:

"Based on the speed and mass of the projectiles fired by the electromagnetic gun, unless 20 base ammunition are added. Otherwise, even if we use up all the shells, we will not be able to complete the deceleration and return home."

The captain looked out the window at the earth that was almost turning into stars, and the corner of his mouth twitched slightly:

"Since we are in space and cannot get so many supplies, please ask Mr. Newton to help us again."

The staff officer's frown suddenly relaxed:

"You mean, according to Newton's second law: the acceleration of an object is inversely proportional to its mass. Since we can't get more acceleration, we should reduce our own weight!"

The captain pointed to the main armor belt that was as smooth as new outside the porthole:

"We dismantle all the main armor and all unnecessary things, and then calculate whether we can return."

Several staff members gathered in front of the computer. Ten minutes later, the staff report reported:

"Captain, although we removed all the main armor belts and non-essential mass, we still can't slow down and return on the spot. However, I calculated a new orbit. We can change the course and catch up with the orbital position of Mars, using

Mars’ gravitational slingshot flings us back to Earth.”

"In addition to the main armor belt, what other equipment is planned to be dismantled?" the captain asked.

"The large equipment includes the other two turrets and all close-in defense artillery systems." the staff officer replied.

The captain asked again:

"How much allowance was taken into consideration for the ammunition for the main gun?"

"In this plan, all ammunition will be consumed to adjust the trajectory, and there will be no surplus." the staff member replied.

The captain thought for a moment and said firmly:

"Four close-in defense guns and corresponding ammunition should be reserved, and a base number of main gun ammunition should be reserved."

Several staff officers looked at each other and recalculated on the computer for a while:

"Captain, if we follow your instructions, we will have to remove the orbiting engine, its fuel tank and more living facilities to achieve the weight reduction goal. This will make our return time longer. According to the current situation

With certain reserves and personnel calculations, food distribution will be very difficult. And..." The staff officer hesitated.

"Say it directly!" the captain ordered.

"Yes! After we reach low-Earth orbit, there will be no auxiliary deceleration from the orbiting engine. We will not be able to park in low-Earth orbit, and we will miss the Earth." the staff member replied.

The captain glanced at the eyes of everyone on the bridge and said decisively:

"We are now lost in deep space. Our return journey will be full of dangers and difficulties. Some of you will stay in space forever before reaching home. However, we must not forget at any time that we are the EDA Space Force.

A member of the human space force. This is a battleship of the human space force.

As long as we have a breath left, destroying the enemy is still our first mission. Therefore, I cannot let the space turret return to Earth as a tiger with its teeth pulled out.

When the warship arrives near low-Earth orbit, if the Space Force is still there, then they will help us slow down and park into orbit. If the Space Force is no longer around, then we will use our main guns to stand guard for the Space Force and humanity.

!”

"The data calculation is feasible, but we must complete the disassembly and deceleration and orbit change as soon as possible. Because in this case, the window for orbit transfer will be very narrow, and we don't have much time." the staff member replied.

Every soldier on the bridge looked as determined as the captain, and no one raised any objections.

"Battery engineer and damage control officer!" the captain called.

No one answered in the queue for a long time. People turned around and looked around, trying to find these two people. But when the space turret entered the high-speed spin, they were repairing the cracks in the sealed cabin at the stern of the ship with the largest centrifugal overload. The powerful centrifugal acceleration crushed the ship.

their ribs and punctured their lungs.

Several staff officers discussed anxiously in low voices. Without the technical guidance of the ship's engineers and damage control officers, it would be almost impossible for the officers and soldiers on the ship to complete the disassembly of the main armor belt in space. The captain's face gradually turned pale.

There were also whispers on the bridge. Ke Guohao hesitated for a while, but finally stood up:

"I am the ship's engineer in charge of electronic equipment. When I was checking the sensors on the truss under the main armor belt, I saw the engineering department and the damage control department replacing single pieces of main armor. I also lived in the same cabin with them.

I usually talk to them about the structure of the main gun and orbital engine. I can give it a try, but I don’t have much confidence."

The captain walked up to Ke Guohao, patted him on the shoulder and said:

"Well done, young man. I believe you can do it!"

Then the captain stood solemnly at attention and said to Ke Guohao in sonorous words:

"I am now recruiting you to officially join the Space Force in accordance with EDA military laws and granting you the rank of lieutenant colonel. I appoint you as the second officer of the Zhenyuan, with full responsibility for the disassembly work. Before the work is completed, everyone, including me, will return to

At your request, please start your work immediately!"

Ke Guohao quickly stood at attention and performed a less than standard military salute:

"Yes! Captain!"

At the same time, everyone in the bridge turned to him and stood at attention, and all gave him a military salute.
