A global storm of dust continues on Mars

A dust storm continues on Mars. The first signs of a small dust storm on Mars were noticed by scientists on May 30th. It has gradually grown in size, eliminating solar energy from the Marshall Opporunity, and by June 20 has become global.

This is reported by the contract.

This storm has become one of the biggest disasters on Mars since the beginning of observations in the 1960s. Therefore, the MRO satellites, Mars Odyssey and Maven are busy studying the dust bubble itself since the orbit, while Marshall's curiosity, which receives energy from the radioisotope generator, comes from the area. 006] Mars Odyssey uses THEMIS device to determine the temperature of Mars.Scientists determine how surface temperature, atmospheric and atmospheric dust evolve as storms change

This data will help determine the mechanism that makes Martian storms Every Martian year during the arid season, there are many local and regional disturbances that are active in some parts of the planet.

But once in 3-4 years (6-8 Earth years), they begin to grow until March. Why this happens, planetologists do not know it yet. On the MRO satellite, two instruments are used to study the storm: the MARCI color camera gives a general overview of Mars during the day and the MCS thermosensor measures the change in temperature of the atmosphere at different altitudes

As on Earth, the temperature of Mars strongly influences the force and the direction. wind The wind, in turn, influences the development of the storm: the sun heats the dust raised in the air, increasing the force of the wind and raising even more dust from the surface

The MCS will allow you to study the details of the process. With changes in the air temperature.

The MAVEN spacecraft is equipped with a set of instruments for the study of the atmosphere of Mars. The satellite does not study the storm itself, but its influence on the upper layers (greater than 100 km) of the atmosphere of a planet where dust does not rise.

It is known that there were several billion years on the surface of Mars. it means that the planet had a dense atmosphere. One of MAVEN's main tasks is to understand the mechanism of the loss of the atmosphere by Mars

Scientists have already determined that reducing the atmosphere of Mars in the current state would require several hundreds of millions of years. Curiosity is the only device that studies the dust storm on the surface of Mars. It determines the number and size of dust particles raised in the atmosphere, as well as how they dissipate and absorb light. The study uses Mastcam, ChemCam and ultraviolet spectrometers in the REMS climate sensor complex

The latter also makes it possible to determine the atmospheric pressure of Mars

According to the planetologists, the dust storm on Mars will last several months .
