Chapter 638 (1/2)

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.
