Looking at the architectural traces on the ground, everyone knows that life and even intellectual civilization once existed on Mars, which is a matter of certainty.

    Of course, this will not be known until after landing and further confirmation.

    In addition, if life and intelligent civilization really existed on Mars, there is definitely not only such a trace of architecture on Mars.

    Sure enough, at this time, someone on board reported: "Captain, orbit probe 636 also found traces of unnatural objects on Mars. According to the data, this unnatural building is a seriously weathered pyramid.

    However, compared with the pyramid on earth, the pyramid on Mars is higher, up to 200 meters high. "

    "Captain, I also found traces of Martian buildings. According to the probe data, this Martian building should be a civilized city of Martian civilization, but now it is basically impossible to subcontract.

    We can only see the general outline. However, because the buildings of the city are built of huge stones, it can still prove that there was a Martian city here, "another report said.

    "There are also on my side, but the scale on my side is even larger. But I don''t know if I''m wrong. This city doesn''t seem to have been destroyed by nature. On the contrary, it seems to have been destroyed by war." another person reported.

    "I have also found abnormal landforms here. According to the analysis of the spacecraft''s central computer, it seems that there have been large river beds here. There is absolutely no need to scale the huge rivers on the earth. But now it is desolate."

    “......”

    “......”

    With the reports from all sides, Captain Qiu and most of the people on the Dijiang were right. There was life on Mars, and it was an intelligent civilization.

    However, due to the deterioration of the Martian environment, all this on Mars has been for hours and has become a desolate and inanimate planet.

    For these, Captain Qiu asked the personnel on the warship to collect the data and immediately play the role of the earth. After all, the discovery of traces of civilization on Mars is also a very important thing.

    With the gradual collection of Martian data to Dijiang, more evidence has been found on Mars to prove the traces of Martian civilization.

    And many staff on the Dijiang also pay close attention to these data, and collect and send them back to the earth at any time.

    After obtaining these data, Wang Bin and others on earth immediately asked people to make a deeper analysis of the data collected in the command center.

    He wanted to know whether there was a civilization on Mars. If there was a highly developed civilization on Mars, how did the Martian civilization disappear.

    Has this civilization fallen in the deterioration of the Martian environment, or has it migrated to other planets, or even disappeared in the war with alien civilizations?

    After all, according to the collected data, many of these found traces of civilization have traces of large-scale war, and many urban traces have large and small giant craters. These giant craters are not like the traces of meteorite impact, but like large-scale lethal weapons such as nuclear weapons.

    At this time, Dijiang continued to collect data from other aspects of Mars.

    The first to send back data is naturally the probes in Mars orbit.

    Although human civilization has obtained some data of Mars through various astronomical telescopes and probes very early, and these data have been very accurate, at this time, Dijiang has been in the long-distance orbit of Mars, and has also launched a large number of probes to the orbits of Mars at all altitudes, So the data they get is more accurate and perfect.

    According to the data, Mars is only about half the diameter of the earth, only 15% of the volume and 11% of the mass of the earth. Its surface is only the size of the earth''s land area. At the same time, in terms of density, it is also the planet with the lowest density in the inner circle of the solar system.

    According to the data, in terms of the radius, mass and volume of Mars, it is only between the earth and the moon. Mars is about twice the diameter of the moon, nine times the mass of the moon, one ninth of the earth, 2.5 times the gravity of the moon and two fifths of the earth.

    The rotation cycle of Mars is 24.6229 hours, that is to say, the rotation cycle of Mars is only half an hour more than that of the earth.

    The revolution time of Mars is much longer than that of the earth. The revolution cycle is 687 days, twice that of the near earth.

    The surface of Mars is basically desert, sand dunes and gravel.

    The ground of Mars does not exist with liquid water. The atmosphere dominated by carbon dioxide is very cold, and there are a lot of sand floating in it. At the same time, dust storms occur on the surface of Mars every year.

    Although the environment of Mars is very bad, many scientists on earth believe that Mars is the most likely planet to have life in the solar system except the earth.

    Although Mars is the outermost planet in the inner circle of the solar system, the distance between Mars and the sun is not very far, with an average distance of 1.52 astronomical units.

    The inclination of Mars''s rotation axis is 25.19 degrees, which is similar to that of the earth. Therefore, there are four seasons, but the length of the season is about twice.

    In addition, the orbit of Mars is elliptical, so the seasonal temperature difference of Mars is also very large, and the temperature difference between perihelion and aphelion is nearly 160 degrees.

    ........

    According to the data of the probe, the density of Mars is very low, only one percent of that of the earth. At the same time, Mars is also very dry, and the composition of water vapor in the atmosphere is very small, or even nonexistent.

    Of course, this is just an exaggeration. In fact, there is still water vapor in Mars'' atmosphere, but it only accounts for 0.003%.

    Mars'' atmosphere is mainly composed of about 95% carbon dioxide, 3% nitrogen, 1.6% argon and 0.15% oxygen. In addition, there are other gases that are less.

    In addition, according to the data of the probe, the temperature difference between day and night on Mars is also very large. During the day, the maximum temperature can reach more than 20 degrees, but at night, the minimum temperature can even reach minus 50 or 60 degrees.

    After seeing all this, the mood of Captain Qiu and others, the professionals in the Dijiang, was very complex.

    After all, according to the imagination of human civilization in the past, Mars should be the easiest planet to transform into a habitable planet in the solar system.

    However, under such circumstances, Mars can really be transformed into a habitable planet. At this time, Captain Qiu and others have a big say of Hello.
