The "Advance" Mars engineering rover is the only one in the manned Mars exploration program that is used for forward base construction, material transportation and short-distance scientific investigation. Because its main responsibility is to carry out construction, and the main equipment on this vehicle is a small crane, digging shovel and rammer, this rover is defined as an engineering vehicle.

As early as the development of the Discovery rover, Dr. Schmitz's team began to develop an engineering vehicle that could be used for construction on Mars, and after more than two years of research, the "Advance" engineering vehicle was finally finalized and finally manufactured by Rockwell International.

The size of this engineering vehicle is very large, twice the size of the "Exploration", so the "Advance" engineering vehicle was not carried to Mars in the cabin of the "Kunpeng" landing spacecraft, but was tied to the outer wall of the "Kunpeng" and brought to Mars.

The "Advance" engineering vehicle uses the same power system as the "Exploration", but the telescopic folding solar panels on its body are larger, and the main energy source is still from solar energy, and the eight nuclear batteries are only backup energy.

If the "Advance" is on Earth, it can build a wooden house at most, but on Mars, where gravity is low, the function of this vehicle is greater. More than ninety percent of the construction work of the entire forward base was completed by the "Advance", so to speak, if there is no "Advance" in this manned Mars exploration plan, then the advance base on Mars will not want to be completed.

Unlike the "Discovery", which is fully enclosed, the "Advance" is equipped with various engineering equipment except for the cab, and the trailer behind it is all equipped with various engineering equipment. Like an electric crane with a dry weight of 500 kilograms, this crane can lift things weighing up to 500 kilograms on Earth, but on Mars, it can easily lift materials weighing up to a ton, and even the "Discovery" rover can be lifted at once.

There is also an excavator blade placed in the rear of the car, which is also powered by electric energy, and can dig out three cubic meters of earth in less than an hour. Of course, if you are on the earth, this amount of earthwork is not even a fart, just take an excavator and go down three times, and dig out more than three square soils. But on Mars, this digging shovel is the supreme weapon for building a forward base.

Others, such as electric rammers and pneumatic crushing bits, have transformed the "Advance" into a comprehensive construction vehicle.

But now, this construction-based engineering vehicle is pulling Han. Together with Comrade Alexander and sufficient supplies, he was heading for the location of the "Discovery" rover overnight. It's just that compared with the "Discovery" rover, which can reach a maximum speed of 60 km/h, the "Forward" has a maximum speed of only 40 km/h, which is far behind.

Han. He and Alexander were driving alternately, and they had been driving for nearly 20 hours, and they were still more than 100 kilometers away from the location of the "Discovery" rover. The two people who were anxious had several big bubbles on their mouths

This side of Han. He and Alexander are in a hurry to rescue thousands of miles, and in the Doug family's Mars base, Tang Feng is communicating with Eric.

"Eric, you can pick up and leave Mars, or go to the other side of Mars, anyway, you can't let my people see you."

Tang Feng's sudden burst out of the words made Eric's face change greatly, didn't the master just now say that he would reward the Doug family with two star cores? Why is this going to drive people out in a blink of an eye!

Seeing Eric's anxious and pale face, Tang Feng also realized that what he said was too abrupt, so he said with a smile: "Eric, I'm not driving you away from me, but at this stage, you are not suitable to appear in front of my people." With the current level of development of the earth's civilization, if you appear rashly, it will cause unnecessary panic. So, you need to leave for a while, and wait for me to find a suitable reason for my people to accept you slowly, so that you can appear by my side openly. Eric, not only is my civilization inseparable from your protection now, but even I need you very much. ”

Eric let out a sigh of relief, and said with a dry smile: "Brother Tang, I really thought you didn't want us just now." ”

Tang Feng laughed and said, "What, scared?" Don't worry, you Brother Tang and I are not such unconscionable people. What I promised you, when I completely control Mars, I will definitely handle it for you. Isn't it just three planetary-level star cores, which I can use to practice! ”

"Three-three?" Eric sensitively caught a key word in Tang Feng's words, and he was trembling and was about to say nothing.

"Well, that's right, it's three. I just said two planetary star cores, which are a reward for your protection of the earth's civilization over the years. As for this third planetary core, this is a decision I have just made, and it is compensation for the expropriation of your Martian base. How about Eric, I don't know if you want this compensation? If you don't want to, I don't need to requisition this base, but I'll still give you two planetary cores. ”

"Ahem, my dear brother Tang, my own brother, how could I not want to? A mere forward base, for our Doug family, is just two Martian days, and I won't take it seriously. Brother Tang, I want that star core, this base will be yours from now on. ”

After a pause, it seemed that he didn't mean enough to express himself, Eric continued: "Actually, Brother Tang, if you don't open your mouth, I will give it to you."

Compared to a small Martian forward base and a planetary star core, it is simply compared to the sun in the sky! Even if it is the lowest non-promotable planetary star core, its value does not know how many thousands of times, how many hundred million times more than this small forward base!

An advance base like this, as long as the Doug family is willing, then dozens of them can be assembled in minutes, feasible star cores, for the Doug family, it is simply an unattainable existence! No member of the Doug family would give up that star core for the sake of such a broken base!

Eric is so knowledgeable, Tang Feng is also very happy in his heart, after all, he is doing the business of occupying the magpie's nest. In Tang Feng's eyes, this base is much more valuable than a star core, after all, his star core is about to be upgraded to the stellar level, and he has also mastered the secret of condensing the star core.

But if Tang Feng is asked to spend money to build such a Mars base, it will be really difficult to reach the sky! Therefore, exchanging the star core for this base is not something that cannot be done in Tang Feng's eyes. (To be continued.) )
