The nuclear bomb was still far away from being launched. After Ye Han announced the reward from his superiors, he ordered his team members to continue hibernating.
Originally, he himself should have been injected with hibernating hormone, but Ye Han was worried about Bai Xiaoting and the children and did not want to hibernate so early, so he used his power for personal gain in a small way.
After the soldiers hibernated, he would send several videos to Bai Xiaoting every day. More than a week later, the Yushan received an order from the Tiangong, and Ye Han reluctantly injected hibernin.
It was already mid-March 2028 when I woke up again. After I woke up and checked the communication records, I learned that the Fourth Fleet had set off on December 26, 2028, and would arrive on Mars in a few days.
The departure time of the fleet was exactly one week after Ye Han stared at the hibernation hormone!
Ye Han was a little dizzy when he saw the news. Didn't he say that he was not fully prepared? Why did he set off immediately? But after thinking about it carefully, he figured out the key.
The reason why this situation occurs is entirely due to the distance between ground and fire.
Simply put, the Earth and Mars are both in motion, and the rendezvous period of the two planets is two years. At this time, the two planets are closest to each other, and the Earth is right between the Sun and Mars. In astronomy, it is called Mars opposition——
The word "opposition" in astronomy means that an outer planet and the sun are on opposite sides of the earth. At this time, the two planets are closest to each other.
There is also a phenomenon called a transit, where Mercury or Venus blocks between the Earth and the Sun.
The last opposition of Mars occurred on February 19, 2027, the day after the departure of the Third Fleet. At that time, the opposition of Jupiter had just ended for half a month. Unfortunately, the target of the Third Fleet was neither Jupiter nor Mars, and it was missed in vain.
A good opportunity to oppose the sun.
By the time the Third Fleet returned, Earth and Mars had already distanced themselves. The fleet approached Mars in order to use Mars' gravitational slingshot to accelerate the fleet and save time on its return, otherwise the Yushan would not stay on Mars.
When the Fourth Fleet set out, it was already close to the end of 2027. At this time, it was close to a year before the opposition of Mars. The Earth and Mars were on both sides of the sun. Although the distance was not the farthest, it was not too far apart. The Fourth Fleet was here.
Starting from time, you must fly from one side of the sun to the other side, which is the longest and longest flight method.
But we can’t do it without setting off. The next opposition of Mars will have to wait until March 2029, and Europa will arrive at Mars in May. If we wait until 2029, it will be too late, so even if we know that the fleet has the longest range, we still have to set off.
In this way, the Fourth Fleet set off at the end of 2027. The fleet flew directly to Venus. It used Venus's gravity to increase its speed and then continued to fly to Mars. Due to the angle problem, the fleet's speed increase was very limited.
In this way, after a long journey of three and a half months, the Fourth Fleet finally successfully flew to Mars - if it flew at full speed, the time could be reduced by another half month, but the acceleration and deceleration of the fleet also took time, so it was delayed by another half month
moon.
In the past, Ye Han might not even be able to think of the reason, but after staying in the fleet for a long time, he was already close to Zhu Zhechi, and he knew more and more about the movement of celestial bodies, so he thought of this reason.
The arrival of the Fourth Fleet means the continuation of the Mars plan. Ye Han and the awakened soldiers immediately got busy and were ready to welcome the Fourth Fleet.
On March 18, 2028, the Fourth Fleet arrived at Mars, and the Yushan and Luzhou were placed under the unified command of the fleet.
The Fourth Fleet of the Expeditionary Force is the most bizarre alternative in the history of the Expeditionary Fleet. The other fleets are mainly battleships, and their missions are to fight aliens. Only the Fourth Fleet is composed of transport ships and super engines, and the number of spaceships
It is also the largest of all expedition fleets, with no less than thirty ships with super engines alone.
Ye Han had a simple communication with the fleet, and then immediately organized the soldiers to start construction.
The construction is not that simple. You must receive the nuclear bombs in order and place the nuclear bombs one by one in the designated well according to the number. It doesn't matter if you make any mistake.
In order to ensure nothing goes wrong, the Fourth Fleet also organized a special quality inspection team. Every placed nuclear bomb must be inspected repeatedly. First, the soldiers inspected it themselves, then Ye Han led Ouyang Ping and Luo Qi to inspect it, and finally the fleet inspected it.
, each inspection must be signed on the document, and which link will be responsible for any problem.
Marines are under unprecedented pressure!
At this time, Ye Han also came to his senses. Installing a nuclear bomb was not a simple matter. There was no more professional team in Beiyue Continent than the Marines. Or why did the higher-ups insist on letting the Marines stay?
The soldiers placed the nuclear bombs in the underground wells one by one according to the number. The next step is to install the super engine on the satellite and wait for the arrival of Europa.
But at this time, there were differences in the plan. According to the original plan, the super engine should be fixed directly on the satellite, and after the satellite was exploded, it would directly push the megaton fragments to crash into Europa.
But now there is a view that even if the power of a nuclear bomb is carefully calculated, a nuclear bomb is still a nuclear bomb. If the super engine is fixed on a satellite, it is difficult to ensure that the engine will not be damaged in a nuclear explosion, and it will be too late to regret it.
This thing has been built in a hurry, and a dozen more can be sent later. Even if it can be built later, it will be too late. If this thing breaks, there will be one less. It is not enough in the first place, why take the risk?
Installed on a satellite?
The new plan is to blow up the satellite first, then use the super engine to get close to it, fix it, and then push the satellite fragments to hit Europa.
But there are also problems. First, Europa is already close when the satellite is exploded, so how long does it take for the super engine to be fixed? Second, the shape of the fragments is irregular, how can the super engine be fixed in the correct position? Third, the explosion
A large amount of debris will inevitably be generated. Will the super engine be damaged in the process of rushing towards the debris? Finally, there is the issue of concealment. Super engines look like man-made objects at first glance and are incompatible with the appearance of the satellite. No matter how stupid the aliens are,
It was obvious that there was something wrong with the satellite.
These are just a few big problems that urgently need to be solved. There are all kinds of small problems that urgently need to be solved by the fleet.
Not to mention the fleet, even Beidu is having a headache over this. Some people even suggested blasting the satellite now and letting the fragments fly around Mars for a while, and then crash into Jupiter when Io comes.
.
The nuclear bomb is buried deep underground, and there is no sound or light effect when detonated. But the aliens are not blind, so maybe they cannot see the satellite shattering? If the aliens are prepared by then, wouldn't they be able to alert the enemy?
If all the preparations were in vain, Ye Han wouldn't even be able to pass this test on his own - why did I abandon my wife and children and stay on Mars?
