China's Zhurong rover successfully landed its mission on May 15, 2021, making China the third country to do so. It's impressive that China's first Mars mission combined orbiting, landing and navigating.

The traveler carries Zhurong, the name of the fire god in Chinese Mythology. Tianwen-1 had left orbit and landed on a vast plain called Utopia Planitia near previous NASA missions. In this region, which is mostly covered with volcanic materials, Zhurong discovered traces of water.

The discoveries of the Zhurong Mars rover were seen as an important step in research into the existence of water on Mars. The Zhurong Mars rover, designed to study the dunes in the Utopia Planitia region of Mars, detected water molecules in the dunes of the red planet as a result of the discoveries and researches.

As a result of his observations on 4 small dunes, Zhurong found that they had cracked layers and ridges on their surfaces. These features were formed as a result of the melting of small pockets of water on the dunes. According to the researchers, these water pockets were formed by the condensation of water vapor from the polar regions of Mars.

The transport of water vapor from the poles to low latitudes is related to the shifting of Mars' axial tilt. The tilt of Mars fluctuates over time, causing the polar ice caps to melt or grow. Researchers estimate that the watermarks on the dunes that Zhurong studied were formed during a change in axis tilt that occurred about 400,000 to 1.4 million years ago.
Zhurong's findings show that water existed on Mars not only in ancient times, but more recently. It also proves that water can exist not only in solid or gaseous form, but also in liquid form.
