I saw that on the big screen, the small half of the asteroid that was blown off suddenly trembled, and then the fire flashed, and it actually exploded a small piece on its own.

Then, under the effect of the recoil force, the speed of the asteroid deviates again.

"This, this, this ......" Charles Bolden had a hellish look on his face, "how is this possible, how can this be?!"

At this time, several minutes have passed since the explosion of the nuclear bomb, and it is a vacuum environment, there is no atmospheric friction, why did the asteroid at the good end suddenly blow up another piece?

The quality and speed of this explosion have changed, adding many variables.

Boldon's face was ugly: "Recalculate the track." ”

Wave after wave of unevenness arose, people got busy again, and a few minutes later, new calculations came out.

"According to the calculations just now......," Aldrich Gerard looked solemn, "after this change, the asteroid will have a high probability of re-impacting the Earth, the good news is that the predicted impact point is the South Pacific Ocean, and it is close to the Antarctic continent, which is an uninhabited area." ”

Lin Han couldn't help frowning: "So, can we intercept it again?"

Gerald shook his head: "Unfortunately, I'm afraid not." It will hit the earth in a dozen days, and in such a short time, we will not be able to prepare the second Defender A1, nor will we be able to find the right time to launch, even if we can modify the existing rocket or missile, it will be completely too late. ”

"What about proximity interception?"

"Ground interception is too costly. If a nuclear bomb is used, destroying the asteroid will also damage the earth, at least the global network communication will be seriously affected. Aldrich Gerrard said slowly.

"If you use conventional missiles, you need to launch a large number of them, they are very expensive, and there is no guarantee of complete destruction. In case a large asteroid fragment flies to Australia and South America, it will be a loss to the wife and a soldier. ”

Lin Han raised his forehead: "So, five billion is just like this, and we have nothing?"

Boldon patted him on the shoulder: "You can't say that, Lin...... At the very least, the size of the asteroid has decreased a lot, isn't it? And as a point of impact, the South Pacific, which is close to Antarctica, is undoubtedly much safer than the Western Pacific, which is close to East Asia. ”

Gerrard also nodded and said, "I think so too, at least there is a 99.99% probability that no one will be injured." I think that's an acceptable outcome, and we don't have to go through the hassle of risking a close interdiction. ”

Charles Bolden thought for a moment: "But I think that after this lesson, people will pay more attention to the threat of asteroid impacts, and the Defender Project should become a long-term scientific research project undertaken by many countries." ”

"You're right. Lin Han had no choice but to nod and say no more.

Perhaps, as some engineers have said, the design of the Defender A1 is not perfect enough, but I hope that in the future, with the concerted efforts of all countries, the subsequent Defender series will be more advanced and avoid this near-complete situation.

With a sigh in his heart, Lin Han turned around and left the hall.

"Gaia, what now?"

"What do you say? Gaia's voice sounded a little depressed.

Lin Han thought for a moment: "It is predicted that the impact point is in the South Pacific Ocean, and it is close to the South Pole, so it is estimated that there will be no casualties." When the time comes, I'll evacuate the animals near the impact site and use the wind to slow down the asteroid to minimize the damage. ”

"Hmm...... That's all there is to it. ”

Gaia added at the end: "The reward is halved." ”

“……”

……

The news of the failure of Defender A1 to destroy the asteroid soon spread around the world through the media and the Internet.

The fact that the United States led and the countries worked together to fail in the end has made people realize that intercepting asteroids is not an easy task.

In fact, if you think about it carefully, you can understand that to a certain extent, the asteroid is actually a super-large ballistic missile, although it can be predicted in advance, but it is far more powerful than man-made missiles.

And intercepting ballistic missiles has always been a big problem, so the failure to intercept an asteroid is not too unexpected.

Either way, it makes the public feel very insecure.

After a long time, it turned out that with the current level of science and technology of mankind, it would be so difficult to intercept an asteroid.

The most terrible thing is that so far, all countries have not really paid attention to this issue, and the five nuclear powers have no intention of working together at all.

The dinosaurs died of their inability to resist, and if this momentum continues, humans may die of infighting and guarding each other.

As a result, public opinion rose for a time, and public opinion was surging, so that hundreds of Nobel Prize-level scientists "jointly signed a letter".

In the end, the P5 finally reached a consensus to establish a long-term scientific research project "Defender Program" coordinated by the Vientiane Environment Committee on the basis of the "Defender Program" of the United States, and to develop the Defender series of launch vehicles, which are specifically designed to defend against extraterrestrial threats.

Of course, the "Defender Project" actually has several secret agreements involving interstellar colonization, which are unknown to the outside world.

The United Nations, the P5 and the Vientiane Environment Committee met every day on the "Defender Plan" in the 10th Power Building, and Lin Han was really busy for a while.

It wasn't until three days before the asteroid impact that he finally took a break to the South Pacific, flew to a small island in the southern hemisphere by private plane, and then secretly got on a small nuclear submarine of the Vientiane Security Company and continued to go south.

The nuclear submarines of the Vientiane Group, of course, were secretly developed, and almost no one knew about them except for the top level of China.

These nuclear submarines are small in size and are equipped with only nuclear power and conventional weapons, but no nuclear weapons.

Driving the nuclear submarine to the vicinity of the predicted impact point, Lin Han began to evacuate the local marine animals, regardless of the big fish and small shrimp, all of them were sent to a thousand kilometers away, away from the impact site.

At the same time, Lin Han also made some changes to the topography of the seabed, subsidencing a large part of the most central impact site, and raising a series of "walls" on the periphery, making the seabed at the impact point into a well-shaped.

In this way, the asteroid will be better cushioned in the event of an impact, and the tsunami will be weakened.

After making all the preparations, Lin Han stayed away from the impact point and waited for the asteroid to come in the sea hundreds of kilometers away.

Not long after, one night, a dazzling light lit up in the eastern sky, dragging out a long tail line, heading straight for the South Pacific, like thunder......
