At the same time, when these data were returned to earth, scientists from the earth command center and other space centers and space companies basically reached the same conclusion as captain Qiu.

    After all, at this time, there are a large number of probes at various heights in the orbit of Mars, and the data provided by these probes show that there is a great possibility of liquid water in the north and south poles of Mars.

    Of course, it''s too early to make a conclusion at this time. After all, I haven''t been to the field, so I don''t know what the real situation is.

    At the same time, with more and more Martian data collected, all aspects of Martian data are constantly being repaired.

    When the spacecraft finally reached Mars'' low earth orbit, some basic data of Mars have been upgraded, such as Mars'' atmospheric structure, Mars'' gravity and so on.

    What they have to do next is to collect data on the ground and soil of Mars. It is obviously much more difficult than collecting data on the atmosphere and gravity.

    And using unmanned detectors, data collection on these aspects is not complete.

    At the same time, due to the location and landform of Mars, there are plains and valleys. Riverbed and other forms and landforms, so the best way is to use a large number of unmanned detectors. In addition, it is best to still land in person for detection.

    Because the only space fighter they carried had returned to earth, they could not use the space fighter to land on Mars for the time being.

    However, fortunately, in addition to carrying a space fighter, they also carry a small aerospace aircraft. They are also a small aerospace aircraft with vertical takeoff and landing capability, that is, Phoenix I aerospace aircraft.

    And because the gravity of Mars is only 25 times that of earth, such profit conditions are enough for phoenix-i aerospace aircraft to take off and land vertically.

    However, although they can land on Mars with phoenix-i space plane, it is obviously much more fragile than space fighters. After all, space fighters have heavy armor, strong power and fierce firepower, which can effectively deal with all kinds of dangers. Even Mars really has a highly developed civilization, The cosmic fighter level of the earth civilization also has the power of World War I. even in case of danger, the maneuverability and institutional ability of the cosmic fighter can retreat calmly.

    But the space plane is different. The space plane does not have heavy armor like the space fighter, nor does it carry a large number of offensive weapons. At the same time, it is far less flexible and fast than the space fighter.

    Compared with space fighters, space planes also have very short legs in endurance, and the fuel they carry can only be used for space planes, which seems to go to Mars.

    The most important thing is that compared with its combat aircraft, the Phoenix aerospace plane needs a runway to take off. Even if it has vertical takeoff and landing capability and can take off and land vertically on the moon, it also needs a certain length of runway to take off after approaching Mars, Take off with the help of the energy of the wings of an aerospace plane.

    In other words, after the space plane lands, the first thing they have to do is to repair a runway that can take off and land for the space plane. Although the length of the runway is not long, it only needs one or two hundred meters. Moreover, because the gravity of Mars is only 25 of the earth, the thickness of the runway does not need to be too thick. It only needs to reach 25 of the earth, But for the people on board, it is also a huge project.

    Even if all the people on the ship were added up to repair the runway, it would take at least a year and a half to complete the repair.

    This is absolutely intolerable to them, but fortunately, although the Phoenix I aerospace aircraft needs a runway, the relatively simple runway can also provide takeoff conditions for the Phoenix and its aerospace aircraft.

    The repair of the relatively simple runway is much simpler for the people in the spacecraft, and the time required is only half a month to a month.

    After all, the spacecraft has been fully prepared before taking off, and considering various situations that the spacecraft may deal with, there are also various engineering machinery and equipment in the spacecraft, such as bulldozers, excavators and so on.

    And these engineering equipment are also very different from the engineering equipment on earth. These engineering equipment are no longer driven by gasoline and diesel.

    After all, on an alien planet like Mars. Because there is no oxygen, gasoline engine and diesel engine can not work, so these engineering equipment are driven by electricity.

    In addition, in order to save energy as much as possible, that is, to save power consumption, these bulldozers and excavators are also equipped with solar panels.

    In addition, there are also small-scale cold nuclear fusion energy supply equipment on the spacecraft to provide energy for these engineering equipment.

    Of course, in order to ensure the safety of construction personnel, these engineering equipment are fully sealed, and there is a perfect life support system inside. Even if the life support system inside machinery such as spacesuit is not worn, it is enough for internal drivers to survive inside for a long time.

    However, because these equipment are engineering equipment, the internal space for storing living materials is very small. They can only supply internal personnel for three or five days.

    At the same time, considering that the volume and quantity of engineering equipment are relatively large and cannot be carried by small aerospace aircraft, these equipment are equipped with special space launch function.

    Even if there is no space plane to carry, the spacecraft can directly put these equipment into the universe and enter the planet to be put. Like the spacecraft of early humans, these equipment can directly use rocket boosters to accurately put these equipment into the place to be put, and then open parachutes and airbags, Ensure that these equipment can operate normally after being put into the predetermined place.

    Therefore, after discussing with the personnel inside the spacecraft, they decided to let the aerospace aircraft and its personnel land on Mars in advance. After selecting a good location, the spacecraft will directly launch these equipment, and then build a simple runway at the fastest speed for the aerospace aircraft to take off.

    Of course, it was not enough for the personnel on the spacecraft to discuss, so Captain Qiu immediately reported the results of their discussion to the earth command center.

    After careful consideration, Wang Bin and Qin Lao of the earth command center also agreed to their request to log in with only Phoenix and aerospace aircraft.

    At the same time, in order to ensure the safety of the personnel in the spacecraft, he sent three Phoenix, two type-1 aerospace aircraft, Phoenix type-2 aerospace aircraft and five space fighters. The main city strike team immediately went to Mars to meet with the spacecraft Dijiang.
