In the following time, the coalition government began to mobilize in all directions, and the construction of the "snow project" officially began.

As an advocate of the "Snow Project" plan, Pang Xuelin was also appointed by the coalition government as the chief scientist of the project and participated in the construction of the "Snow Project".

To Pang Xuelin's surprise, two days later, he met Yao Bingxia and Du Jiaxiang and others who escorted the first batch of metal-based graphene composites to Hope City.

The earth passes through the asteroid belt, and it is inevitable that various accidents will occur, and the hope city where the coalition government is located is one of the safest areas on the entire earth, and the arrival of Yao Bingxia has made Pang Xuelin feel a lot more at ease.

With the official launch of the snow project, Pang Xuelin has truly seen the world's aerospace technology level.

According to the preliminary plan of the snow project, humans will launch 2,000 nuclear bombs containing metal-based graphene matching materials and moth them into the designated location calculated by the engineers.

All 2,000 nuclear bombs were launched from the earth, and the vehicles carrying these nuclear bombs were actually fusion-powered aerospace planes.

Compared with the three-body world and the Martian world that Pang Xuelin experienced before, the level of aerospace engineering on the Wandering Earth is obviously more than a step higher.

With a weight of more than 500 tons and a take-off weight of more than 1,500 tons, these aerospace planes can carry nearly 1,000 tons of fuel and cargo, freely travel to and from geosynchronous orbit, and have a self-sustaining power in space for several months.

Compared to the combined-powered space shuttles in the Martian world, this kind of space plane is not a product of the same era at all.

Pang Xuelin also specially looked for the technical data of these fusion-powered aerospace planes and space warships.

He found that the fusion reactor used in the aerospace aircraft is the product of the miniaturization of deuterium-tritium nuclear fusion, and the maximum power can reach the million kilowatt level, which can almost meet the electricity consumption of a small and medium-sized city in the real world.

With such a huge energy output, it is no wonder that dozens of modified flints can be lifted into the air at one time.

If it weren't for the size of the flint, it could have been loaded.

As for those space battleships, it is even more exaggerated, a random one has a total mass of more than 100,000 tons, which is several times larger than the International Space Station in the Martian world.

It is said that the maximum speed of these space battleships can be accelerated to 2,000 kilometers per second (in principle, if the battleship has enough fuel in space, it can accelerate infinitely until the relativistic effect is produced, but under normal circumstances, after the battleship accelerates, it also needs enough fuel to ensure deceleration, and in addition, it is necessary to maintain the basic operation of the battleship, so the maximum speed will be calculated according to the maximum speed that can be achieved by consuming one-third of the fuel to accelerate), and it can last in space for two to three years in the absence of replenishment.

Of course, what shocked Pang Xuelin the most was the Navigator International Space Station, which is said to be a space station, but in fact it is also a super battleship.

With a total tonnage of more than one million tons, it is almost equivalent to a space city and can accommodate up to more than 100,000 astronauts.

It is said that inside the space station alone, there are three nuclear fusion reactors, which are redundant to ensure that even if the two fusion reactors are damaged, the remaining one reactor can still maintain the normal operation of the space station.

Pang Xuelin has not seen the real body of the Navigator space station, but it can be seen from the pictures that the Navigator space station is many times larger than the space station shown in the movie.

Therefore, it is not a problem for mankind to deploy hydrogen bombs in the asteroid belt at fixed points.

Aerospace aircraft carry flint to dock with space warships parked in geosynchronous orbit, which then transport flint and drop it into the corresponding location near the Earth's shipping path in the asteroid belt.

Time passed, the snow project progressed in an orderly manner, and before the Earth officially entered the asteroid belt, the snow project finally completed all the deployment of hydrogen bombs.

Subsequently, these hydrogen bombs were detonated one by one, forming huge dust clouds 10 million kilometers west of the Earth's shipping lane.

After another week of testing, it soon became clear that these dust clouds tracked the asteroid even better than Pang Xuelin had predicted.

Any asteroid with a diameter of more than 10 meters, after passing through these dust clouds, can show a clear trajectory on the radar screen from 10 million kilometers away.

The snow works were a great success.

The only regret is that because of the limited production of metal-based graphene materials, these dust clouds cannot cover all the waterways, and can only monitor the key waterways.

But even so, the presence of these dust clouds has greatly reduced the workload of the space fleet, expanding the space fleet's warning range to 2 million kilometers of the Earth's shipping lanes, greatly increasing the Earth's reaction time.

……

Half a month later, the Earth officially began its journey through the asteroid belt.

With the exception of a handful of staff who had to be on duty on the surface, most of the people on the surface were evacuated into the dungeon.

The space fleet also began to get busy, and in the earth wheelhouse, Pang Xuelin saw the scene of an antimatter bomb destroying an asteroid for the first time in the planetary engine control center.

Through the footage captured by the space battleship's external camera, Pang Xuelin saw that an asteroid with a diameter of 200 meters appeared in the warning range of the space fleet.

Subsequently, the space fleet launched an interstellar missile equipped with an antimatter bomb warhead, which spanned tens of thousands of kilometers and accurately hit the asteroid.

At the moment when the antimatter bomb exploded, even after tens of thousands of kilometers, the camera lens was completely covered by a white light, until more than ten seconds later, this white light gradually disappeared, and the previous location of the asteroid, the asteroid with a diameter of nearly 200 meters has completely disappeared.

It is said that on the ground, the flash of light produced in the shape of an antimatter bomb instantly illuminates the entire eastern hemisphere in the middle of the night, as if a super sun suddenly appeared in the sky.

Such a bright light, if viewed directly with the naked eye on the ground, may directly lead to blindness.

And this is only the energy that erupts after 100 grams of antimatter and positive matter are neutralized (one gram of antimatter produces energy equivalent to a thermonuclear bomb with a yield of 40 million tons), but it is enough to smash the asteroid into thousands of pieces.

Due to the gravitational effect of the Earth, a day or two later, these asteroid fragments descended on the Earth.

Countless spectacular fire meteors began to appear in the sky.

Only some of these meteors burned up in the atmosphere, and most of the rest fell in the Southern Hemisphere.

From the footage captured by drones and ground surveillance cameras, it can be seen that a fire meteor is like a heavenly punishment, turning into a brilliant fireball under the friction of the atmosphere, and instantly hitting the frozen ocean.

A white mushroom cloud of water vapor rose into the sky, and the thick layer of ice rumbled and shattered, completely shattering the plane within a radius of several kilometers, and the ice took on the shape of a wave, slowly spreading out, and then decaying as the frozen ocean decayed.

Finally, in the drone's footage, the ice sheet within a few hundred meters of the impact site has re-melted into seawater.

And this is just the damage caused by a fire meteor less than a meter in diameter.

What's even more terrifying is the scene when a fire meteor with a diameter of tens or hundreds of meters hits the ground.

In the early twentieth century, an asteroid with a diameter of twenty or thirty meters fell near the Shiquan Tunguska River in Krasnoyarsk Krai, Russia, causing a massive explosion that flattened about 500,000 acres (2,000 square kilometers) of Siberian forest and created an impact crater with a diameter of 100 meters.

Later, scientists believed that the Tunguska explosion was about 10 to 20 megatons of TNT, which was 1,000 times more powerful than the atomic bomb dropped on Hiroshima.

Impact scenarios like the Tunguska explosion happen every day.

And sacrifice followed.

On the second day after the Earth entered the asteroid belt, there was already a scene of space fighters cleaning up asteroids being hit by asteroid debris, resulting in the death of the pilot.

Even a week later, a space battleship was hit by a high-speed asteroid fragment in the fusion reactor, killing more than 10,000 people in an instant.

The biggest tragedy occurred when the earth entered the asteroid belt for a month, and an asteroid that is close to 100 meters so far entered the atmosphere, in the atmosphere, the asteroid and the atmosphere friction broke into three pieces, one of which changed its orbit and finally hit the New Delhi 2 engine, directly causing the New Delhi 2 engine to refusion core module melting.

The core module burned down the emergency exit to the dungeon, and the lack of sufficient power left the dungeon unable to stop the magma invasion, and finally 400,000 people in the dungeon of New Delhi were buried alive by the scorching magma.
