After all, a phoenix-i space plane can only carry less than 20 people at a time, and build an aircraft runway, even the simplest runway. Nor can it be built by these people in a short time.

    What''s more, although there are some engineering construction personnel in the spacecraft Dijiang, the number is very small, only a few people.

    So if you really want to build an aircraft take-off runway on Mars, even the simplest aircraft take-off runway. It also requires a large number of professional personnel for construction. Otherwise, the built runway is very dangerous to make the aerospace aircraft take off safely.

    Moreover, according to the previous estimates of the engineers on the spacecraft, even if it is to build a simple runway of one or two hundred meters, even if it takes more than a month for everyone on the spacecraft to participate, which is very unfavorable to the scientific research progress on Mars and will definitely greatly delay the exploration on Mars.

    Re dispatch aerospace aircraft from the earth and carry professional engineering and construction personnel. It only takes less than 15 days to reach Mars. After all, the space technology of human civilization is no longer the space technology a few years ago. If it was a few years ago, the cauliflower will be cold when the spacecraft reaches Mars.

    Now, if the spacecraft and the space plane go to Mars at full speed, it will take only a little more than a week to arrive. In this way, the scientific researchers on the spacecraft Dijiang can also concentrate on scientific research and exploration without considering others.

    What''s more, with the full-scale exploration of Mars and the subsequent construction of military bases on Mars, special engineering and construction personnel are required to analyze the landform of Mars first, so as to determine which area is more suitable for construction in the north and south poles of Mars.

    As for other places on Mars, neither Wang Bing himself nor the officials nor the professionals on the spacecraft Dijiang have considered it.

    After all, according to the data obtained by Wang Bin and his colleagues, the whole Mars except the traces of water resources found in the north and south poles of Mars. So far, no trace of water has been found in other places, let alone liquid water.

    Therefore, if we want to build military bases or survival bases in other parts of Mars, the water needed for the survival and production of internal personnel must be transported from the earth or mined from Mars.

    This will be a great waste of resources, which is simply not feasible for the current human civilization.

    After all, even if it seems that human civilization has begun large-scale space activities, human civilization has completely entered the era of interstellar civilization. However, all parties on the earth have tightened their belts at this time, including Wang Bin and their Tiangong technology.

    Because of this, today''s earth and human civilization have no redundant resources to waste, not to mention that human civilization will face the threat from alien civilization.

    Although, according to the "sea" from the blue star civilization captured by human civilization, he said that in the future, it is not the regular civilization that will come to the solar system, but the remnant fleet of the pirate regiment from the blue star civilization.

    But whether Wang Bing himself or the top of the earth, he also holds a skeptical attitude towards this.

    The most important thing is whether the fleet seen by human civilization with the help of large radio telescopes is the "sea". It remains to be discussed. Even he can''t confirm it. After all, the fleet is still a few light years away from the solar system.

    In other words, if this fleet is not the remnant fleet of the pirate regiment in the mouth of the alien civilization, but a fleet of other civilizations from outside the solar system, the earth human civilization will not only face the remnant fleet of the pirate regiment in the alien population. And deal with this unknown fleet that will reach the solar system.

    So what human civilization should do now is to build the most powerful solar system defense system at the least cost, including military bases on Mars and other bases.

    It is precisely because of this, whether it is the high-level of the earth, experts in all aspects of Tiangong technology and Wang Bin himself, have set their eyes on the north and south poles of Mars, which are very likely to have liquid water resources.

    Although the temperature of the north and south poles of Mars is much lower than that of other places, it is not impossible for modern humans.

    What''s more, this is a military base. It doesn''t need to build the whole South Pole or North Pole of Mars into a building like a huge city.

    "Has the data detected by the ground probe been collected on Mars? What is the current resource situation? Can it meet the basic requirements of industrial production?" asked the personnel of the opening team responsible for data collection of Martian ground soil and other aspects as the captain of the post Dijiang spacecraft when Dijiang spacecraft was preparing to send an aerospace plane to Mars.

    "Report, Captain! According to the data currently detected, Mars is actually a very barren planet compared with our earth, and even far less abundant than our earth''s satellite, that is, the moon, in terms of overall resource reserves and types of resources." the professional in charge of this aspect handed a data report to captain Qiu.

    This data report is the data collected by a large number of unmanned ground probes sent by them.

    Although the data collected by unmanned ground probes may not be very accurate, it will not be much worse.

    After all, the ground probe will also collect soil and rock samples on the Martian ground when collecting Martian ground data. Use internal professional equipment for analysis, and then send it back to the central computer of the spacecraft, and then gather by the central computer of the spacecraft, and then analyze again.

    Captain Qiu, after receiving the data report, looked at it carefully.

    According to this data, the Martian soil is also composed of many components, of which the highest content is oxygen, accounting for about 50%, followed by silicon, accounting for about 15-30%, iron, about 15-16%, aluminum, about 2-7%, and calcium, about 3-8%.

    In addition to these elements, Martian soil also contains a small amount of, potassium, phosphorus, sulfur, copper, nickel, cobalt, magnesium and other elements.

    It can be said that compared with the earth, my heart is definitely a barren planet, which makes everyone on the spacecraft very disappointed.

    Although there are a large number of iron elements on Mars, with the real entry of human civilization into the cosmic era, common elements such as iron are very common in the universe. It is said that there are countless other asteroids containing iron in the asteroid belt, which is enough for human civilization. Now and for a long time to come.

    What''s more, compared with Mars, although the ball is the earth''s satellite, there are still a lot of helium 3 resources on the moon, which is the main source of thermonuclear fusion fuel for human civilization. It can be said that compared with the moon, Mars really has nothing good except that it is larger.

    Of course, this is only what has been detected at present. With the in-depth exploration of Mars, many people in the spacecraft believe that Mars will never be as barren as people think.
