Armor Frenzy

Beidu rejected the idea of ​​detonating in advance and continued to implement the original plan, but the original plan was not foolproof.

The specific time of Io's arrival can be calculated, and the detailed orbits of Phobos and Deimos can also be calculated, but Io's current orbit cannot fly to the earth at all, and it must change direction near Mars .

At that time, it is impossible to determine where Io is approaching Mars from, and the orbital altitude cannot be determined at all. As a result, the distance and positional relationship between the satellite and Io cannot be determined.

If you want to hit Io Zero, the timing is very important. Too early is equivalent to reminding aliens, and too late and suddenness is equivalent to giving Io Zero a chance to evade calmly, so exactly when to detonate is the success of the plan and the difference. The key to no is that when the detonation is detonated, the satellite cannot be too far from Io, and the flying speed of the fragments must be fast enough.

However, although the planetary engine is strong, the quality of Io is not low, and its steering and acceleration and deceleration are very troublesome. As long as the speed of the fragments is fast enough, it is not impossible to hit Io.

If not, there is no need to continue the Mars plan, just declare failure and return to Earth to wait for a decisive battle with the aliens.

The differences in the plan were resolved, and the Mars plan entered the fast lane. The first problem that the Fourth Fleet needed to solve was the placement of the super engine.

The impact of not releasing the super engine on the mission is too serious, and it must not be done. In order to prevent the impact of the nuclear explosion from destroying the engine, the fleet has come up with an unexpected method: build a shelf!

To put it simply, it is to find several hundred-ten-meter-long giant steel cones. The head of the cone is fixed at the designated position on the surface of the satellite, and the tail of the cone is fixed on the super battleship, which is equivalent to fixing the super engine on the satellite with a shelf.

The depth of the steel cone inserted into the satellite, the length left outside and the angle of insertion into the ground have been carefully calculated. When the nuclear bomb explodes, the steel cone is the buffer between the fragments and the engine. The steel cone will be deeply inserted into the fragments due to inertia. Completed super engine fix.

The super engine has a very high self-weight. If it is placed on the earth, it will definitely not do this. Even the gravity of the moon can bend the steel cone. Only a small celestial body with low gravity like Phobos can use this method to fix the spacecraft.

On April 6, 2028, the last superengine was anchored to the surface of the satellite.

The success of the super engine has fixed the last obstacle to the Mars plan, and the next task is to wait for the arrival of Io Zero.

In order to prevent aliens from discovering the super engine, Ye Han also took the soldiers to cover the engine with camouflage nets, disguising all the super engines as hills on the surface of the satellite.

This is not a temporary intention of Ye Han and others, but a task arranged before the fleet departs.

Ye Han was very suspicious of the effect of the camouflage net, but it was better than nothing.

The Marines finished laying all the camouflage nets in just two days. At this time, it was more than a month before Io arrived. Except for a few people in the Fourth Fleet who stayed to monitor Io, all the others were injected with hibernin.

At this time, Yushan has completed all tasks and can leave Mars to return at any time. However, the distance between the earth and Mars is still relatively far, and secondly, Io Zero is about to arrive. After Ye Han solicited the opinions of all officers and soldiers, he applied for a temporary stay. Mars, a follow-up mission to the Mars program.

After careful consideration, Qiongzhou Base agreed with Ye Han's suggestion.

Qiongzhou Base also doesn't know what to do with the Marine Corps, but there is no hurry to come back at this time. It's best if you don't need it. What if you can't find someone if you need it?

On May 20, 2028, Io is only three days away from Mars, and the fleet will wake up everyone and wait for the arrival of Io.

Io is getting closer and closer, and its position can be seen clearly with the naked eye. Although all the ships of the Fourth Fleet are painted black, in order to prevent the fleet from being exposed, all the ships are hidden behind the satellites and only installed on the The monitoring equipment on the satellite observes Io Zero, and all the spacecraft are constantly moving their positions under the unified command of the flagship to ensure that all the spacecraft can be blocked by the satellite.

At 4:00 a.m. on May 23, Io was only two hours away from Mars. The Fourth Fleet was in full force. Everyone on the bridge of the flagship Nanzhou was performing their duties. Wang Tianyu reported Io's every once in a while. track parameters.

That's right, it's Wang Tianyu, not only him, but also Ling Yu.

Originally, the Fourth Fleet was less than a few of them, but because of the failure of the Third Fleet, Ling Yu and others strongly requested to join the Fourth Fleet, and they asked Menluto to issue a military order. Opportunities for the Fourth Fleet.

This is also due to many objective factors in the failure of the Third Fleet. Otherwise, the blood of the whole body will be written dry, and the Fourth Fleet will not be able to turn to these few people.

Of course, the voyage experience of the Third Fleet also gives Ling Yu and others a lot of points... There are not many senior commanders with voyage experience~www.readwn.com~ The long wait is slowly passing, when the wood When Wei Zero was only half an hour away from Mars, Wang Tianyu finally got the orbit analysis results: "Report, Commander, the orbit analysis results are out, Io Zero will arrive at Mars in twenty-seven minutes, with an orbital altitude of 10,000 taels. Thousands of kilometers."

"What? Only 28,000 kilometers? Are you sure?" Ling Yu turned pale in shock, staring blankly at the home screen, "What the **** are the aliens trying to do?"

Instead of doubting the results of the orbital analysis, he was shocked by the madness of the aliens.

Twenty-eight thousand kilometers is a very long distance for man-made aircraft, but it is too close for Mars or Io.

Although Ling Yu's astronomical knowledge was limited, he didn't know what would happen if the two planets were too close, but the distance was less than four times the diameter of Io's zero, which was too close.

Xu Moriang's expression was almost frozen: "Judging from the current orbit of Io, it really wants to use Mars to slow down..."

Ling Yu's eyes never left the home screen. There was a real-time map of the situation near Mars. Right now, Europa was flying in front of Mars, and Deimos was just behind Mars. The closest distance between the two was expected to be no less than fifty thousand. Kilometers, even if Deimos is blown up immediately, the fragments generated will not be able to catch up with Io.

The relative speed between Io and Deimos is as high as more than 80 kilometers per second. Although the power of the super engine is good, it can’t catch up with tens of millions of tons of boulders, unless the boulder is thrown away. Use the super engine to drive Zero's tail.

But then it would be useless to catch up even if the super engine collided with it, at most it would be a tickling for Io Zero.

However, there is no such thing as a unique path, and the position of Deimos is not good, but Phobos happens to be on the other side of Mars!
