"Five, four, three, two, one - launch!" The host shouted passionately, and bright flames burst out from under the buttocks of the space shuttle on the screen, and then turned into a torrent of flames, and the space shuttle, which stood firmly in front of the launch frame, took off slowly, and then became faster and faster, turning into a sharp arrow piercing the sky in a blink of an eye. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Hundreds of millions of viewers watched the launch via live streaming, all staring intently at the sky-high aircraft on the screen, with expressions of concern or anticipation.

Flying into the sky is only the first step of the launch, and there are not no precedents for the space shuttle to disintegrate or explode in the air after launch.

Thirty seconds later, the shuttle broke through the sound barrier, and two minutes later, the flame flow under the solid rocket booster disappeared and successfully separated from the main body.

Eight minutes later, the main engine was shut down, the outer tank was separated from the main body of the shuttle, and Houston announced the successful launch.

Hundreds of millions of people around the world who are following the progress of the launch are jubilant.

However, the space shuttle was only initially successfully launched, and more than 40 minutes later, the space shuttle activated its thrusters under the remote control of the ground, began to correct its orbit, and finally stabilized the space shuttle in a near-circular orbit at an altitude of 400 kilometers.

The launch and orbit change of the space shuttle were extremely carefully calculated, and after the orbit was stabilized, its position was just not far below the ISS, and after a period of position adjustment, the space shuttle slowly approached the ISS like a homing bird.

The ISS stretched out its slender manipulator in time to firmly grasp the approaching shuttle and secure the shuttle under the space station.

The space station issued a command to open the hatch, the cargo hatch of the space shuttle opened to both sides, and the astronauts and engineers who had been stationed in the space station a few days in advance collectively poured out of the airlock and slowly floated towards the space shuttle with a safety rope.

It wasn't until they successfully arrived at the shuttle that they cut the safety rope and entered the cabin to take control of the shuttle.

Then the manipulator on the space station sent the reactor in place in advance to the space shuttle, and the personnel on the space shuttle immediately began to fix the reactor, connecting the lines and control system.

After the reactor was installed, the shuttle closed the outer hatch, and the space station handed the electromagnetic railgun to the shuttle, which was fixed to the shuttle's back by the crew in the form of a spacewalk.

In order to reduce weight, the electromagnetic gun removed all unnecessary burdens, and in addition to the main body, only two and long rails were laid flat on the back of the aircraft, almost extending from the tail to the nose.

This electromagnetic cannon was not originally so long, but it was temporarily strengthened in order to increase the firing power.

Fortunately, there is no interference such as gravity in space, and engineers only need to consider the bearing capacity of the orbit itself, and do not have to study the effect of gravity on the trajectory.

The installed reactor and electromagnetic cannon immediately began to test the machine, and the news of the normal operation of the reactor reached the earth, and the heads of state breathed a sigh of relief at the same time, and the news of the normal operation of the electromagnetic cannon was sent back to the ground, and the cheers of forgetfulness sounded between heaven and earth at the same time.

Finally, the space station added experimental electromagnetic propulsion from Tiangong to the space shuttle, and the four-day assembly project was successfully completed.

Although it was only a patchwork of space shuttles, nuclear reactors and electromagnetic railguns, the modified space shuttle, although humble to the extreme, was still the first actual space warship in human history, and the original name of the space shuttle immediately became history, renamed the Earth.

The Yankees originally planned to name the humble warship USS America, but were unanimously opposed by all the allies, and had to compromise and name it after the more distinctive symbol of the earth.

Successful assembly meant that the plan was halfway through, and after the engineering staff were evacuated, only two astronauts from the United States would be left on board the shuttle - one of the minimum conditions proposed by the United States, in exchange for the complete relinquishment of control of the other space shuttles.

Subsequently, the Earth detached from the space station, docked with dozens of spacecraft in orbit, received the ammunition and materials on the spacecraft, and successively fixed various functional modules on the surface of the Earth.

At the same time, another space shuttle was launched and docked with Tiangong, and the technicians who were originally stationed on the International Space Station also took the spacecraft to get out of the space station, docked with Tiangong after orbit change, and carried out a comprehensive modification with the equipment provided by China and Russia.

At this time, there is still a month and a half before the asteroid masses fly to the Earth, and the asteroid group is still 1.5 billion kilometers away from the Earth, and it is flying from the direction of the Sun to the Earth.

The Earth, which was the first to complete the modification, immediately set off in the direction of the asteroid swarm, and set sail with indomitable determination.

A few days later, the Humanity set sail.

The remaining two space shuttles were not originally planned to be launched, but after the completion of the modification of the Earth and Mankind, there were a lot of materials left in orbit, and after the five major powers got together to study it, Britain and France cooperated in depth to purchase the active reactor on a Chinese nuclear submarine, and bought electromagnetic guns from the United States, and compensated for the launch of the space shuttle to a certain extent.

As for whether the reactor was dismantled from a submarine, no one knows -- China is a regional power with strength and heritage, so it doesn't matter where it came from?

A few days later, the third space shuttle was successfully launched, and the control of this modified space shuttle was owned by Britain and France, and it was eventually named Victory.

However, the Chinese side only has two electromagnetic thrusters, and the traditional propulsion method is too fuel-intensive, and the unpowered Victory cannot sail far, so it can only stay in high-altitude orbit and act as the last barrier for mankind.

The Russian side is trying its best to gain the ownership of the fourth space shuttle, although the Russian side did not say it explicitly, but the emaciated camel is bigger than the horse, even if it is difficult to independently modify a space shuttle, it is a good choice to purchase some equipment, or even exchange technology with the Chinese side for equipment.

After arduous negotiations, the Russian side reached an agreement with the American side to sell the last space shuttle to the Russian side.

However, although the space shuttle was successfully launched, it had a problem during the orbit change and fell into the atmosphere helplessly.

After the incident, the Russian side openly and covertly accused the United States of deliberately damaging the space shuttle, but the United States argued that there was absolutely no such thing, and neither side could produce convincing evidence, nor did it have time to carefully examine the launch data, and the cooperation between the two sides finally came to an end.

The already contradictory relationship between the two countries, which had been tempered by cooperation against the asteroid group, has become strained again, casting a heavy shadow over international cooperation. (To be continued.) )
