The probe found a duck on Mars. How did this happen?

At present, Mars is in winter, and the incidence angle of sunlight is relatively low, which leads to the formation of carbon dioxide frost on the surface of sand dunes, and the early thawed sand is exposed, forming such a spectacular image of many "ducks". This is also the first photo in a series of seasonal changes of Mars observed by the probe.

In the past people's cognition, Mars was a desolate planet with dead sand everywhere. However, with the constant discovery of probes on Mars, especially the geomorphological features of the surface of Mars washed by water, scientists speculate that Mars was also a planet full of liquid water a long time ago. Like the earth, it also has a strong atmosphere, and there may be some form of life.

If there is a large amount of liquid water under the surface of Mars, it is of great significance for human beings to establish bases on Mars in the future, and even for future Martian immigrants. We must know that human beings can't live without water. Therefore, in the future, human beings must have water to choose the planet to migrate to, and Mars is also the highest planet that scientists have been expecting to change.

If there is no water on Mars, then we may have to give up the plan to transform Mars into a habitable planet, but now we have finally found some evidence that there is water on Mars, which is good news for mankind. However, if life is found on Mars, it may not be good news for human beings. In different planetary environments, the life born must be different. Take the simplest microorganism as an example. The largest biological groups on the earth are bacteria and microorganisms.
