The Environmental History of Mars

The past and present lives of Mars. Both Mars and Earth were formed about 4.5 billion years ago and initially had the conditions for life to develop. 3.8 billion years ago, Mars had a high-density atmosphere, warm climate, and large oceans of liquid water. However, due to its low gravity and weak magnetic field, Mars lost its water and atmosphere under the influence of the solar wind, becoming dry, cold, and turning its surface into a desert. And the Earth, on the other hand, maintains its vitality due to moderate gravity and magnetic field.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

During the formation of the solar system, Mars and Earth were truly 'siblings'. They both formed about 4.5 billion years ago and initially had suitable conditions for nurturing life. Previous studies have shown that approximately 3.8 billion years ago, Mars had a denser atmosphere, a warmer climate, and large oceans composed of liquid water. However, due to its low gravity and weak magnetic field, Mars lost most of its water and atmosphere, becoming dry and cold, and its surface gradually turned into a barren red desert. The Earth, with moderate gravity and magnetic field, remains lush and vibrant. The exploration of the Martian environment and life is not only related to the question of the origin of life, but also to the fate and future of humanity. With the continuous research on fire exploration, one day humans may establish a Mars base, and even transform Mars into a second habitat for humans, "said Jiang Yun, associate researcher at the Astrophysics and Planetary Science Laboratory of Purple Gold Mountain Observatory.
