While everyone was waiting anxiously, new data came from Mars''s large orbital resource probe, and these data were transmitted back. After the analysis of Dijiang''s central computer, Captain Qiu and various professionals inside Dijiang spacecraft were ecstatic.

    That is, after analyzing the data scanned by the probe, the computer concluded that there is indeed liquid under the south pole of Mars.

    Although, since human civilization began to explore Mars, in recent decades, many scientists have firmly believed that there must be liquid water below the very low surface of Mars, and it is like the polar region of the earth.

    According to the data at that time, it is inferred that the groundwater in the Martian polar region is likely to be hidden below 1.5km.

    This caused a great sensation at that time.

    The researchers at that time said that if liquid water really existed in the polar underground of Mars, Guangyu would have a chance to prove the past and present of life on Mars.

    At that time, many people were also skeptical about this. After all, it was very difficult for human civilization and technology at that time to explore a few kilometers deep underground in the polar region of Mars hundreds of millions of kilometers away.

    The second is whether the underground liquid in the Martian polar region is really liquid water. After all, at such a low temperature, the underground liquid in the Martian polar region may be other substances, such as liquid methane, liquid carbon dioxide and so on.

    Now, Captain Qiu''s large orbital resource probe has also detected traces of liquid under Mars, and the location is less than two kilometers from Peng Ming''s landing point.

    According to the data scanned by the detector, the underground lake, which is not far from Peng Ming''s landing point, covers a large area of about 30 kilometers.

    Of course, this is the area of the whole underground lake, including the upper ice sheet. If the upper ice sheet is removed, the underground area covered by suspected liquid water also has a size of nearly ten kilometers.

    In addition, in addition to observing the underground lake, the detector also found the existence of several underground lakes nearby. However, compared with the underground lake closest to the landing point, the volume of other underground lakes is much smaller.

    The largest one is only about 56 square kilometers, and the smallest one is only two or three square kilometers.

    In addition, the probe has also scanned more underground lakes within a 300 kilometer area centered on the probe, the largest of which is larger than the underground lake closest to the landing point, with at least 100 square kilometers.

    The scientists in the other command center and the Dijiang spacecraft simply couldn''t help themselves with such a discovery.

    After all, in the past, human beings on earth basically launched only small detectors. Even some resource detectors in Mars orbit are limited by their internal volume and launch weight. Therefore, the performance of instruments and equipment inside the detector is greatly limited, which can not be compared with those launched by Dijiang.

    Now, the probe launched by Dijiang has also found the existence of underground lakes in the polar regions of Mars. Then, it is certain that there is really liquid underground in the polar regions of Mars, and it is likely to be liquid water.

    However, there is another thing that everyone regrets, that is, according to the data, if the liquid in these underground lakes is really liquid water, these liquid water is not fresh water, but salty or very salty. Its salt content is very high, at least far higher than that of the saltiest water in the earth''s Shanghai Ocean.

    Therefore, these underground lakes are not suitable for the survival of life if only taking the salt on the earth as an example.

    However, life is synonymous with miracles, so even if the water in these underground lakes on Mars is really salty, it may not be lifeless. After all, there is life in the earth''s Shanghai Ocean, even in the crater with the worst environment, not to mention the salty environment.

    In addition, compared with the data detected by previous probes launched by human civilization, the data detected this time is more accurate. For example, previously, the Mars probe launched by human civilization only detected the underground lake closest to the landing site, which is covered with ice at least 1.5km thick.

    However, the probe data launched by the Dijiang show that the ice layer covered on the underground lake is 1559 meters, which is still the thinnest thickness. If the average thickness is calculated, the ice layer on the whole underground lake has a thick bottom of at least two kilometers.

    In addition, the depth of liquid water in the underground lake is also very deep. According to the data, the deepest part of the underground lake is at least 15 kilometers deep, that is, the deepest part of the underground lake is deeper than the deepest Maria trench on earth.

    You know, this is not the largest underground lake they found. In addition, they also found a larger underground lake. However, compared with this underground lake, the larger underground lake is deeper and covered with thicker ice.

    However, this is not a problem for today''s human civilization. As long as it is found, mankind will definitely have a way to mine it.

    In addition, since the probe has found a large number of underground lakes at the south pole of Mars, does it mean that there are many underground lakes in the north pole of Mars, just like the South Pole?

    .......

    Just as Dijiang and the command center were excited to see the data sent back by the Mars orbiting large resource probe.

    At this time, the Chinese people on the spaceplane at the landing point have also made preparations before landing. At this time, everyone is chatting excitedly.

    "Please make the final preparations before getting out of the cabin. Everyone begins to check whether his teammates'' spacesuits are ready. You know, this is Mars, not the earth.

    The temperature outside the space plane has now reached more than minus 130 degrees. Even in another two hours, the temperature will at least be about minus 100 degrees.

    Once the spacesuit is not properly worn, I don''t think I need to say more about the consequences.

    So you must pay attention. In addition, you should also pay attention not to leave the space plane too far. After all, the climate of Mars is very changeable, and the maximum wind speed of Mars is also very fast. Even if you wear an exoskeleton armored spacesuit, its wind can blow you to the sky.

    Therefore, once you find something wrong, please return to the space plane immediately. Although the shell armor of the space plane may be far inferior to that of the space fighter, it is enough to deal with the wind on Mars.

    Most importantly, in order to prevent the strong wind from Mars from blowing away the aircraft, several huge drill bits were stretched out from the belly of the aircraft at the first time after landing, which deeply drilled into the ground and firmly fixed the aircraft in place.
