Reasons for four seasons on Mars – Sciencetimes revealed


NASA's Mars Curiosity research vehicle arrived at the 2012 Garret Crater. And after analyzing the air from 2014, we can confirm that 95% of the carbon dioxide in the atmosphere has been reached.

Oxygen was only 0.16%, indicating that various living things, such as the Earth, cannot live. The rest of the atmosphere was filled with gases such as nitrogen (2.6%), argon (1.9%) and carbon monoxide (0.06%).

The amount of gas in the atmosphere causes seasonal changes

Research has been conducted recently to discover new facts about the season. In particular, the mechanism reveals how the gases that make up the atmosphere circulate and create seasons.

NASA's Mars Research Program (MEP) announced today that researchers have analyzed atmospheric gases that fill the surface of the Galle Crater and have been able to measure seasonal changes for the first time.

This is the first time we have analyzed how Mars seasonal changes have occurred since the Mars study.

According to the study, the seasonal changes on Mars begin in the Antarctic and Arctic regions where carbon dioxide is frozen. If carbon dioxide is too frozen in winter, the pressure is reduced because the gas is reduced throughout the atmosphere.

In the spring and summer, however, temperatures in the Antarctic and Arctic regions decrease and frozen carbon dioxide begins to evaporate. It mixes with gases in other atmospheres, increasing the pressure on the whole atmosphere.

The researchers were able to discover new facts about the seasons as nitrogen and argon in the atmosphere were constantly changing in proportion to the amount of carbon dioxide in the atmosphere, serving as an indicator of seasonal changes.

Researchers found that the amount of gasoline that covers the Gayle cluster through nitrogen and argon increased by about 30% as it enters spring and summer (compared to winter), and begins to decline when it enters autumn, returning in winter.

The paper was published in the 12th issue of the journal Geophysical Research (Planets). The title is "Seasonal Variations in Atmospheric Composition as Measured in King Gale, Mars".

Increase or decrease the amount of methane by 60%

Oxygen is what the researchers first expected as an indicator for atmospheric analysis.

Mars' seasonal exploration began with oxygen. However, as the season changes, the amount of oxygen changes improperly. In this situation, oxygen cannot explain the reason for seasonal changes. But that role was replaced by nitrogen and argon.

Professor Suhil Atrea, a professor of atmospheric and space scientists from the University of Michigan who participated in the study, said in a press interview that "The new incredible principle of" Pressure equalization "in the atmosphere of Mars through nitrogen and argon. I found the facts. “

The reasons why oxygen cannot be an indicator of atmospheric phenomena on Mars are explained.

"The change in oxygen is not an important problem in explaining the atmospheric dynamics of Mars," said Melissa Trainer, a planetary scientist at NASA's Goddard Space Center.

But because oxygen is so closely linked to life, scientists studying Mars are interested in methane, which can replace oxygen.

Studies show that 0.00000004% of the methane is buried in the Galle crater, but the amount is too small to be identified by analytical devices.

However, Dr Trainer said: "Samsung's TDLS (Adaptive Laser Spectrometer), built in Curiosity, confirms that seasonal changes in the amount of methane occur."

Even he said, "the amount is increasing by about 60 percent." "I still can't explain the reason," Dr Trainer said.

Researchers are currently trying to determine the cause of methane.
