An international team of researchers Martian atmosphereDiscovered how and why dust is generated on the surface, and the investigation was reflected in the article on the cover of the latest issue.Science Advances “..
February 2021 NASA’s Mars 2020 mission has arrived on Mars On the surface of Jezero Crater Start driving self-driving cars PerseveranceMobile laboratory.
One of his instruments MEDA Meteorological ObservatoryDeveloped at the Center for Astrobiology-INTA in Madrid, in collaboration with the Planetary Sciences Group at the University of Basque (Northern Spain).
Analysis of the data provided by MEDA allows us to delve into one of the atmospheric aspects of the Red Planet. Dust that emerges from the surfaceAnd the signatories were featured in articles including UPV / EHU Professor Ricardo Hueso, Agustín Sánchez Lavega, Teresa del Río-Gaztelurrutia, and PhD student Asier Munguira.

“We can say that we are beginning to understand the conditions necessary to generate dust from the surface of Mars. This is an important factor. The dust cycle of the Red Planet gives a better understanding of Mars’ global meteorology. Because it helps, “explains Ricardo. Hueso. , The second author of the article.
Because the atmosphere on Mars is much thinner than the atmosphere on Earth (about 1/150 density). Dust in the air determines many of its thermal properties and how it is heated and cooled.
“Science Advances” article
We are studying phenomena that generate dust on the surface of Mars, such as dust devils and gusts that can generate large dust devils.
Thanks to the data collected in Wind, dust, temperature, and other atmospheric variablesJezero Crater, which was selected as the research site for the Mars 2020 mission, is today a desert, but because of the floods billions of years ago, it is the most active and preferred place to raise large sums of money. We conclude that it is one. Dust from its surface.
As explained in the article The daytime wind is getting stronger And, in general, intense, At night, the detected winds descend and weaken... “The interaction of these wind flows with the surface causes these massive dustlifting phenomena,” Hueso shows.

Dust from the atmosphere of Mars, when deposited on the surface, can cover solar panels and cause some surface space missions to fail. However, this is not a problem for the Perseverance Rover, which uses nuclear power to operate.
Hueso says that knowing the atmosphere of Mars today is essential to understanding Mars’ past and to “prepare for human exploration of Mars”, which he hopes will happen “in the coming decades”. I add that there is.
over it, “Nature“On-site recordings of the Martian soundscape, including recordings of the first sounds in the atmosphere of Mars, will be released this week. UPV / EHU’s IBeA group, supervised by Professor Juan Manuel Madaliaga, participated in the article and was one of the signatories of the previous article, student Ashie Mugira.
As the records reveal, the thin atmosphere of Mars causes different acoustic phenomena than those on Earth. For example, the dispersion of sound at different frequencies in the human audible spectrum, or the greater attenuation of sound over distance. Low atmospheric density.
