There was no situation in the asteroid belt for the time being, and Ye Han immediately retracted his divergent thoughts and put all his attention back to Mars.

As he saw, the Joint Command attaches great importance to Mars, the Combined Fleet has just arrived, and the accompanying transport ships have already carried out a series of landing surveys on Mars, landing craft have landed in batches, the north and south poles of Mars are full of creeping crawler drills, and a large number of soil and rock samples have been sent back to the warship for the most detailed analysis by professionals.

Landing on Mars is easy, but staying there for a long time is not so simple, not only to determine the condition of the soil and rock formations, but more importantly, to determine the direction of the underground ice veins!

The water on Mars is concentrated in the north and south poles, so the fleet prioritizes the geology of the poles, and once the direction of the underground ice veins is determined, a reasonable landing site can be determined according to the ice vein conditions, and the next step is to start building a permanent Martian base.

As for whether the two sides will build alone or the two sides will work together, it is not something that Ye Han can worry about.

The exploration of Mars has not yet been inconclusive, and the work on Phobos has begun.

Ye Han found that Phobos was focusing on more than a dozen transport ships, and dozens of landing craft were constantly going back and forth between satellites and spacecraft, transporting a large amount of supplies to Phobos.

A batch of engineering equipment has been sent to Phobos, and they move around the surface of Phobos, even in the craters that were left behind.

Seeing this scene, Ye Han couldn't help but sigh at the wonder of the world, back then, he never imagined that he would have such a day in the future.

Phobos was originally small, but after being bombed by the expeditionary force, the size was further reduced, and the fleet quickly surveyed the situation of Phobos and determined a suitable construction location.

So another batch of construction machinery was sent to Phobos, which attached to the surface of Phobos, cut rocks, and excavated underground space, intending to build a small space base on Huobos first.

Ye Han briefly understood that this space base is not as simple as it seems, its construction is divided into several steps, the goal of the first stage is to dig a small amount of underground space for the housing of reactors and corresponding maintenance personnel, and then lay out laser arrays to turn Deimos into a mobile battery to protect Mars.

This is a plan that has been set for a long time, and the transport ship is carrying sufficient supplies, and it is expected that the entire project will be completed in about a week.

After the end of the first phase, the construction on Phobos will be suspended indefinitely until humans have established themselves on Mars and can use the Martian resources for subsequent construction.

The goal of the second phase is to continue to excavate underground space and install various support equipment, with the ultimate goal of hollowing out Phobos and turning it into a space base for the Combined Fleet, which can hold an entire fleet of war fortresses.

At the end of the plan, there is also an imaginary picture of the completion of Phobos, which is full of technology and violence, and it does look like a fortress of war, and even calls this fortress "an unsinkable Martian battleship".

Ye Han almost didn't get embarrassing cancer, the fortress is the fortress, I have to add an unsinkable one, and I don't want to think about how big Phobos is, just throw a few nuclear bombs and blow up the scum and never sink, isn't this?

On the whole, Phobos's development plan is very good, but Mars is not the moon, and it is not so easy to gain a foothold here.

Mars is now poor and white, I don't know what year and month I have to wait for this day, in case aliens call, hehe, it's hard to say whether the first phase of the project can be saved, the second phase? Let's wash and sleep.

Deimos also has a transformation plan, Ye Han also found out the plan out of curiosity, and almost vomited blood when he turned the first page, isn't this the plan just now? In addition to turning Deimos into Deimos, even the punctuation marks are exactly the same!

But I finally found something different when I turned to the back, the construction period and imagination of Deimos are different from the previous one, although the ultimate goal is to turn the satellite into a fortress, but the volume of Deimos is much smaller than Deimos, and the difficulty of building is reduced by several grades at once, according to the plan, when there are conditions in the future, the construction of Deimos will be prioritized.

Ye Han couldn't help laughing, this plan was really long-term enough, but in his opinion, the so-called fortress was a joke at all, if the combined fleet couldn't stop the aliens, no matter how powerful these two fortresses were, it would be impossible to keep the aliens out of the orbit of Mars.

On the contrary, if the combined fleet blocks the aliens, these two fortresses will at most defend Mars, and they will have no effect on the earth, and there is no difference between having and not having it.

Ye Han didn't know that on the first day of the fleet's arrival on Mars, all actions were controlled to a minimum, and to put it simply, it was mainly tentative.

However, the project of Phobos was not as smooth as that of Phobos, because the expeditionary force planted a large number of nuclear bombs on these two satellites, and all of them were detonated, but the ones on Phobos have been buried there, and the engineers must first pick out all the nuclear bombs one by one before they can work on that little guy with peace of mind.

The next day, July 18, the fleet launched a large-scale exploration operation, and within one day, more than 400 construction machines of various kinds were put into operation, and more than 2,000 engineers were employed, half of whom were marines.

Soldiers can't do real technical work, but manual work such as moving and moving is called handy...... This refers to the Command!

On the 20th, the preliminary survey of the North Pole ended; The 21st Antarctic survey was completed, and a location was determined at the north and south poles.

When the coordinates were sent to the surface, the engineers immediately took action, drilled several inclined shafts tens of meters deep at the designated location, and then filled the wells with explosives, and everyone evacuated the scene.

There was an earth-shattering explosion, and countless earth and rocks flew into the sky, and when everything was over, there was already a huge inclined shaft with a depth of nearly 100 meters on the originally good ground.

A large number of engineering personnel and engineering equipment rushed into the inclined shaft to clean up the gravel under the shaft as quickly as possible. As for the uneven wall of the well, it is not at all concerned.

The large and small gravel was only cleaned to the well, and there was no intention of sending it to a distant place at all.

When the shaft was almost cleared, more than a dozen transport ships flew to the North Pole of Mars in a neat formation, suspended over the North Pole, and airdropped supplies to the predetermined coordinates.

Container-like drop pods are all manufactured to military standards, and each container has a set of guidance equipment that allows them to land in their intended position as precisely as a guided bomb.
