Environmental Geochemistry of Mars-Characteristic Analysis

1, an essential element to sustain life

Although Venus has always been called the sister star of the earth, the environment of this hot planet is too unsuitable for human habitation. On the other hand, Mars is the second closest planet to the Earth. Although it is still a cold and dry planet, it has all the necessary elements to sustain life, including:

Water, carbon and oxygen that may exist in frozen form on the polar ice sheet of Mars exist in the form of carbon dioxide.

(carbon dioxide), nitrogen.

The atmosphere of Mars today is strikingly similar to that of the Earth billions of years ago. When the earth was first formed, it looked like a desolate barren land without oxygen. The atmosphere consists entirely of carbon dioxide and nitrogen. It was not until photosynthetic bacteria evolved on the earth that enough oxygen was produced, so animals evolved. Similarly, the thin atmosphere on Mars is almost entirely composed of carbon dioxide.

2. Composition of the Martian atmosphere

95.3% carbon dioxide

2.7% nitrogen

1.6% argon

0.2% oxygen

In contrast, the earth's atmosphere consists of 78. 1% nitrogen, 20.9% oxygen, 0.9% argon and 0. 1% carbon dioxide. From this detailed comparison, it can be seen that all human beings who visit Mars now have to carry a lot of oxygen and nitrogen to maintain their lives.

3. Temperature

The average surface temperature of Mars is as low as -62.77℃, the highest temperature is 23.88℃, and the lowest temperature is below -73.33℃. In contrast, the average temperature of the earth's surface is about 14.4℃.

Comparison before and after Mars transformation.

Similarity feature

However, Mars has several characteristics very similar to the Earth, which makes people think it is a place to live, including:

The rotation rate is 24 hours and 37 minutes (Earth: 23 hours and 56 minutes).

The inclination of the axis of rotation is 24 degrees (23.5 degrees for the earth).

Gravity is one third of the gravity of the earth.

It is close enough to the sun, so there are four seasons. Mars is 50% farther from the sun than the earth.
