Eight Hundred and Seventy Fifth Time Flies
highly recommended:
The nuclear bomb was far away, and after Ye Han announced the rewards from his superiors, he ordered the team members to continue hibernating.
Originally, he himself should also inject hibernation, but Ye Han was worried about Bai Xiaoting and the child, and didn't want to hibernate so early, so he used his power for personal gain.
After the soldiers hibernated, he had to send a few videos with Bai Xiaoting every day. After more than a week, Yushan received an order from Tiangong, and Ye Han reluctantly injected hibernation.
It was mid-March 2028 when I woke up again. After waking up, I checked the communication records and found out that the Fourth Fleet had set off on December 26, 2028, and was about to arrive at Mars in a few days.
The departure time of the fleet was exactly one week after Ye Han watched the hibernin!
Ye Han was a little dizzy when he saw the news, didn't it mean that he was not prepared enough? How do you say that you set off? But after thinking about it a little bit more carefully, he figured out the key to it.
The reason for this situation is entirely caused by the distance between the ground and the fire.
Simply put, both the earth and Mars are in motion. The rendezvous period of the two planets is two years. At this time, the distance between the two planets is the closest, and the earth is just between the sun and Mars. In astronomy, it is called Mars opposition. The word astronomically means that an outer planet and the sun are located on both sides of the earth, and at this time, the distance between the two planets is the closest.
There is also a phenomenon called a transit, that is, Mercury or Venus blocks between the earth and the sun.
The last Mars opposition occurred on February 19, 2027, which was the second day after the Third Fleet’s departure. At that time, Jupiter’s opposition had just ended for half a month. Unfortunately, the third fleet’s goal was neither Jupiter nor Mars, so it was in vain. A good opportunity to hit the sun.
When the third fleet returned, the distance between the earth and Mars had already been widened. The purpose of the fleet approaching Mars was to use the gravitational slingshot of Mars to accelerate the fleet and save the return time. Otherwise, Yushan would not have stayed on Mars.
It was close to the end of 2027 when the Fourth Fleet set off. At this time, it has been nearly a year since Mars opposed the sun. The earth and Mars are on both sides of the sun. Although the distance has not reached the farthest, it is not too far away. Starting from time, one must fly from one side of the sun to the other, which is the farthest and most time-consuming way of flying.
But it’s impossible not to set off. The next opposition of Mars will have to wait until March 2029, and Io will arrive at Mars in May. It’s really too late to wait until 2029, so even the fleet that knows the furthest voyage must set off.
that's it,
The fourth fleet will set off at the end of 2027. The fleet will fly directly to Venus. With the help of the gravity of Venus, it will increase its speed to a certain extent and then continue to fly to Mars. Due to the angle problem, the speed increase of the fleet is very limited.
In this way, after a long journey of three and a half months, the Fourth Fleet finally successfully arrived at Mars. If it flew at full speed, the time-consuming could be reduced by another half a month, but the acceleration and deceleration of the fleet would also take time, so it was delayed for another half a month.
In the past, Ye Han might not have even thought of the reason, but after staying in the fleet for a long time, he is also considered close to Zhu Zhechi, and he has more and more understanding of the movement of celestial bodies, so he thought of the reason for this.
The arrival of the Fourth Fleet means the continuation of the Mars plan. Ye Han and the awakened soldiers immediately got busy and got ready to welcome the Fourth Fleet.
On March 18, 2028, the Fourth Fleet arrived at Mars, and both 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 the aliens. Only the Fourth Fleet is composed of transport ships and super engines, and the number of spaceships It is also the crown of all previous expedition fleets, with no fewer than thirty ships with super engines alone.
Ye Han had a simple communication with the fleet, and immediately organized soldiers to start construction.
The construction is not that simple. You must receive the nuclear bombs in order, and place the nuclear bombs in the designated wells one by one according to the number. It doesn't matter which one is wrong.
In order to ensure nothing goes wrong, the Fourth Fleet also specially organized a quality inspection team. Every placed nuclear bomb must be inspected repeatedly. , Every inspection must be signed on the document, which link will be responsible for any problem.
Marines are under pressure!
By this time, Ye Han had come to realize that installing a nuclear bomb was not an easy task, and there was no team more professional than the marines in Beiyuezhou, or why did the higher-ups insist on letting the marines stay?
The soldiers placed the nuclear bombs in the ground well one by one according to the number, and the next step was to install the super engine on the satellite, waiting for the arrival of Io.
But at this time, the plan diverged. According to the original plan, the super engine should be directly fixed on the satellite, and when the satellite is exploded, it will directly push the megaton-level fragments to crash into Europa.
But now there is a view that even if the power of the nuclear bomb is carefully calculated, the nuclear bomb is still a nuclear bomb. If the super engine is fixed on the satellite, it is difficult to ensure that the engine will not be damaged in the nuclear explosion, and it will be too late to regret it.
This thing was built in such a hurry, and more than a dozen more can be sent later. Even if it can be built in the future, it will be too late. If this thing breaks down, there will be one less. If it is not enough, why take risks? Put it on a satellite?
The new plan is to blow up the satellite first, then use the super engine to push it up, fix it, and then push the satellite fragments to hit Jupiter.
But there are also problems here. One is that Jupiter was already close when the satellite was blown up, and how long it would take for the super engine to fix it; A large number of fragments will inevitably be produced. Will the super engine be damaged in the process of rushing towards the fragments? Finally, there is the issue of concealment. The super engine is a man-made object at first glance, which is incompatible with the shape of the satellite. It should be seen that there is a problem with the satellite.
These are just a few big problems that need to be solved urgently, and there are all kinds of small problems that need to be solved by the fleet.
Not to mention the fleet, even Beidu is troubled by this. Some people even proposed to explode the satellite now, let the broken pieces of the satellite fly around Mars for a while, and then hit Europa when it comes. .
The nuclear bomb is buried deep in the ground, and there is no sound and light effect when it is detonated, but the aliens are not blind, so maybe they can't see the satellite shattering? When the aliens are ready, wouldn't they startle the snake?
If all the preparations are in vain, Ye Han won't even be able to pass his own level. I gave up my wife and children, and what is the reason for staying on Mars?
