Eight Hundred and Seventy-Six Everything Is Ready

Beidu rejected the idea of ​​early detonation and continued to implement the original plan, but the original plan was not foolproof.

The specific time of Jupiter's arrival can be calculated, and the detailed orbits of Phobos and Deimos can also be calculated, but Jupiter'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 from what position Jupiter approaches Mars and what the orbital height is. In this way, the distance and position relationship between the satellite and Jupiter cannot be determined.

If you want to hit Jupiter, the timing is very important. If it is too early, it is equivalent to reminding the aliens. If it is too late, it will be sudden, which is equivalent to giving Jupiter a chance to evade calmly. Therefore, when to detonate is the key to the success of the plan. The position of the satellite and Jupiter cannot be too far when detonating, and the flying speed of the fragments must be fast enough.

However, although the planetary engine is strong, Jupiter's mass is not low, and its turning and acceleration and deceleration are very troublesome. As long as the speed of the fragments is fast enough, it is not impossible to hit Jupiter.

If not, the Mars plan would not have to go on, and it would have been declared a failure, and it would have been enough to return to Earth and wait for the final battle with the aliens.

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

Not placing the super engine would have a serious impact on the mission, so it was definitely not possible. In order to prevent the impact of the nuclear explosion from destroying the engine, the fleet came up with an unexpected solution: build a rack!

Simply put, it is to find a few giant steel cones that are hundreds of meters long, with the cone head fixed at a designated position on the surface of the satellite and the cone tail fixed on the super battleship, which is equivalent to using a rack to fix the super engine on the satellite.

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

The super engine has a very high self-weight. If it is placed on the earth, it will definitely not work like 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 super engine was fixed on the surface of the satellite.

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

In order to prevent aliens from discovering the super engine, Ye Han also led the soldiers to cover the engine with camouflage nets, disguising all 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 to have it than not.

The Marines laid all the camouflage nets in just two days. At this time, there was more than a month before Jupiter arrived. Except for a few people who stayed to monitor Jupiter, all others in the Fourth Fleet were injected with hibernation hormone.

At this time, the Yushan has completed all its tasks and can leave Mars and return at any time. However, the distance between the Earth and Mars is still relatively far, and Jupiter is about to arrive. After consulting all officers and soldiers, Ye Han applied to stay on Mars temporarily to participate in the follow-up tasks of the Mars plan.

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

Qiongzhou Base did not know what the Marines could do, but there was no rush to come back at this time. It would be best if there was no need. What if there was a need but no one could be found?

On May 20, 2028, Jupiter was only three days away from Mars. The fleet woke up everyone and waited for Jupiter to arrive.

Jupiter was getting closer and closer, and its position could be seen with the naked eye. Although all the ships of the Fourth Fleet were painted black, in order to prevent the fleet from being exposed, all the ships were hidden behind the satellites, and only the surveillance equipment installed on the satellites was used to observe Jupiter. All the ships were constantly moving under the unified command of the flagship to ensure that all the ships could be blocked by the satellite.

At 4 a.m. on May 23, Jupiter's moon was only two hours away from Mars. The Fourth Fleet was on full alert. Everyone in the bridge of the flagship Nanzhou performed their duties. Wang Tianyu reported the orbital parameters of Jupiter's moon every once in a while.

Yes, it was Wang Tianyu. Not only him, but Ling Yu was also there.

Originally, they were not allowed to join the Fourth Fleet, but because of the failure of the Third Fleet, Ling Yu and others strongly requested to join the Fourth Fleet, and they found ways to use their connections to issue military orders, and even wrote blood letters, so that they could get the opportunity to command the Fourth Fleet.

This is also because there are many objective factors in the failure of the Third Fleet. Otherwise, even if they wrote blood all over their bodies, they would not have the Fourth Fleet.

Of course, the long-distance sailing experience of the Third Fleet also added a lot of points for Ling Yu and others... There are not many senior commanders with long-distance sailing experience.

Time passed slowly during the long wait. When Jupiter was only half an hour away from Mars, Wang Tianyu finally got the orbital analysis results: "Report, Commander, the orbital analysis results are out. Jupiter will arrive at Mars in 27 minutes, with an orbital altitude of 12,000 kilometers."

"What? Only 28,000 kilometers? Are you sure?" Ling Yu was shocked, staring blankly at the main screen, "What on earth do the aliens want to do?"

He did not question the orbital analysis results, but was shocked by the madness of the aliens.

28,000 kilometers is a very long distance for man-made aircraft, but for Mars or Jupiter, this distance is too close.

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

Xu Moliang's expression was so serious that it almost froze: "From Europa Zero's current orbit, it does want to use Mars to slow down..."

Ling Yu's eyes never left the main screen, where there was a real-time situation map near Mars. At present, Europa Zero was flying in front of Mars, and Deimos was just behind Mars. It is estimated that the closest distance between the two is no less than 50,000 kilometers. Even if Deimos was blown up immediately, the resulting fragments would not be able to catch up with Europa Zero.

The relative speed between Europa Zero 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 you throw away the boulders and use the super engine to chase Europa Zero's tail.

But in that case, even if you catch up, it will be useless. The super engine will at most tickle Europa Zero.

However, there is always a way out. The location of Deimos is not good, but Phobos happens to be on the other side of Mars!
