UV radiation on Mars can be compatible with some forms of life
UV radiation doses obtained from the surface Marti They are similar to those that should be present in Tira Primitive results, analysis and subsequent results revealed that these levels can be Compatible with some forms of life.
An international study, led by the Center for Astronomy (CAB) – of the Higher Council for Scientific Research (CSIC) and the National Institute of Air Space Technology (INTA) revealed doses of ultraviolet radiation that reaches the surface of Mars from the data collected by the ROPER Environmento Monitor) He fell in 2012 in the storm holeNear Ecuador on the planet.
The search results were published on Monday in the magazine The facts of the National Academy of Sciences (PNAS), which is the result of analysis More than five years of Mars (That is, the equivalent of more than ten years of ground) of various types of UV rays on the Red Planet, including UV-C radiation, The most harmful to living organisms.
On Earth, UV-C radiation is absorbed by the ozone layer that protects the planet, but the atmosphere of Mars, although ozone contains. About 100 times more dark Thus, it is not protected in the same way, as it reached the solar radiation in practice completely to the surface, the cabin was shown in a note issued on Monday.
Radiation is much higher than radiation on the ground
The decrease in the protection provided by the Mars atmosphere in front of the ultraviolet radiation due to the suspended dust, which is especially related to the station Dirt storms.
The results of this study appear Very radical and rapid differences At ultraviolet radiation levels, capable of changing doses in more than 30 % in a few (Mars Days), the cabin noted, which indicated that these differences Sophisticated and unpredictable With current weather models.
Although ultraviolet radiation doses on Mars are much higher than those on the current land, their levels Similar to those who think they are present In primitive land, when life arose and developed.
Despite its sterile power, this study shows that the radiation that the surface of Mars is connected “It is not completely inconsistent with life.”This may not be sufficient to eliminate all microorganisms that travel on space tasks.
Therefore, it is necessary to continue to apply strict measures for Planet protection To avoid pollution of Mars with terrestrial life, especially in future inhabited tasks, the Astronomy Center has warned.
NASA’s curiosity explorer is formed by NASA through a set of tools that are recorded, at the level of Mars, air temperature, pressure, pressure, pressure, Relative humiditySoil temperature, speed and direction of wind and ultraviolet radiation.
These measures are closely related to the three main goals of the task that NASA has made more than ten years ago: Check the biological capabilities of the area that has been explored For the car, it checks the operations of the planets that occur on its surface and that affect its capacity, such as water, and the levels of radiation that reach the surface of Mars.
