Eight Hundred and Seventy Sixth, Everything Is Ready

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 Europa’s arrival can be calculated, and the detailed orbits of Phobos and Deimos can also be calculated. However, Europa’s current orbit cannot fly to the earth at all. It must change its direction near Mars. .

At that time, there is no way to determine the position of Jupiter approaching Mars and the altitude of the orbit. In this way, the distance and positional relationship between the satellite and Jupiter cannot be determined.

If you want to hit Zero, the timing is very important. If it is too early, it is equivalent to reminding the aliens; The key point is that the position of the satellite and Jupiter should not be too far away when detonating, and the flying speed of the fragments must be fast enough.

However, although the planetary engine is strong, the quality of Zero is not low. 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 Zero.

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

Having resolved the differences in planning, the Mars project entered the fast lane. The first problem that the Fourth Fleet needed to solve was the placement of super engines.

Uninstalling the super engine would seriously affect the mission, so it must not be done. In order to prevent the impact of the nuclear explosion from destroying the engine, the fleet came up with an unexpected method: put on airs!

To put it simply, it is to find a few giant steel cones with a length of 100 meters. The cone head is fixed on the designated position on the surface of the satellite, and the cone tail is fixed on the super battleship, which is equivalent to fixing the super engine on the satellite with a frame.

The depth of the steel cone inserted into the satellite, the length left outside, and the angle inserted into the ground have all been carefully calculated. When a nuclear bomb explodes, the steel cone acts as a buffer between the debris and the engine. The steel cone will be inserted deeply into the debris due to inertia, thereby Finished super engine fixation.

The super engine has a very high weight. If it is placed on the earth, it must not be able to do this. Even the gravity of the moon can bend the steel cone. Only small celestial bodies with low gravity such as Phobos and Deimos can use this method to fix the spacecraft.

On April 6, 2028, the last superengine was fixed on the surface of the satellite.

The successful fixation of the super engine has cleared the last obstacle of the Mars plan, and the next task is to wait for the arrival of Io.

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

This was not a temporary idea of ​​Ye Han and others, but a task arranged before the fleet set off.

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

It only took two days for the marines to lay out all the camouflage nets. At this time, there was still more than a month before the arrival of Ion Zero. Except for a few people from the Fourth Fleet who stayed behind to monitor Ion Zero, everyone else was injected with hibernin.

At this time, Yushan has completed all tasks, and can leave Mars and return at any time. However, the distance between the earth and Mars is still relatively far, and secondly, Jupiter is coming. After consulting the opinions of all officers and soldiers, Ye Han applied for a temporary stay Mars, participating in the follow-up mission of the Mars program.

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

The Qiongzhou base doesn't know what the Marine Corps can do, but there is no rush to come back. At this moment, it is best if there is no need. What if there is a need but no one can be found?

On May 20, 2028, Zero Jupiter is only three days away from Mars. The fleet wakes up everyone, and everyone takes their places to wait for Zero Jupiter to arrive.

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

At 4 a.m. on May 23,

Jupiter is only two hours away from Mars. The Fourth Fleet is on standby. Everyone on the bridge of the flagship Nanzhou is performing their duties. Wang Tianyu reports Jupiter's orbital parameters every once in a while.

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

Originally, the Fourth Fleet was not their turn, but because of the failure of the Third Fleet, Ling Yu and others strongly demanded to join the Fourth Fleet, asked for a relationship to issue a military order, and even wrote a blood letter, so they won the command Opportunities for the Fourth Fleet.

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

Of course, the voyage experience of the Third Fleet also gave Ling Yu and others a lot of points... There are not many senior commanders with voyage experience.

Time passed slowly after the long wait, and when Jupiter Zero was only half an hour away from Mars, Wang Tianyu finally got the orbit analysis result: "Report, Commander, the orbit analysis results are out, Jupiter will be on the 2nd. It will reach Mars in seventeen minutes, at an orbital altitude of 12,000 kilometers."

"What? It's only 28,000 kilometers? Are you sure?" Ling Yu was shocked, staring blankly at the main screen, "What the hell are the aliens trying to do?"

He didn't question the results of the orbital analysis, but was shocked by the madness of the aliens.

Twenty-eight thousand kilometers is a very long distance for man-made spacecraft, but for Mars or Europa, this distance is really too short.

Although Ling Yu's astronomical knowledge is limited, he doesn't know what will happen if the two planets are too close, but this distance is less than four times the diameter of Io's zero, which is too close.

Xu Morliang's expression was so serious that he almost froze: "Judging from Judging from Jupiter's current orbit, it really wants to use Mars to slow down..."

Ling Yu's eyes never left the main screen, where there is a real-time situation map near Mars. Right now, Europa is flying in front of Mars, and Deimos is just behind Mars. It is estimated that the shortest distance between the two is not less than 50,000 Kilometers, even if Deimos is blown up right now, the resulting fragments cannot catch up to Europa.

The relative speed between Europa and Deimos is as high as more than 80 kilometers per second. Although the power of the super engine is good, but pushing tens of millions of tons of boulders will not catch up, unless you throw the boulder directly Push Io's tail with the super engine.

But it would be of no use to catch up in that case, the super engine hitting it would at most tickle Io Zero.

But there is no such thing as an absolute path, Deimos is in a bad position, but Phobos is just on the other side of Mars!
