NASA has shown a new image of Mars, which captures the constant activity of the so-called dust devils that circle the surface of the Red Planet. These huge dust devils form, move across the surface and disappear before other similar phenomena take their place, writes ScienceAlert..

The image was taken using the HiRISE camera installed on board the Mars Reconnaissance Orbiter spacecraft, which orbits Mars. It shows the surface of Mars, where dust devils have left their mark on the landscape. Scientists are studying the trajectories and speed at which dust accumulates on Mars, helping them better understand atmospheric processes on the Red Planet.
Mars is often called the Red Planet due to its reddish color, which is caused by iron oxide in the soil.. The atmosphere of Mars is thin and mainly composed of carbon dioxide, which contributes to a cold climate with average temperatures of approximately minus 60 degrees Celsius.
The surface of Mars is covered with plains, extinct volcanoes and vast canyons.. Geological evidence suggests that Mars once had liquid water and a thicker atmosphere, suggesting the possibility of life in the past.
The atmosphere of Mars also consists of small amounts of nitrogen, argon and oxygen. This thin atmosphere has a density of only about 1% of the density of the Earth's atmosphere, and therefore people cannot live on the surface of the Red Planet without the use of special shelters.
Despite the fact that the atmosphere of Mars is thin, it is very active and one of its most exciting phenomena is the emergence of dust devils. These swirling columns of dust and air that look like tornadoes on Earth.
These dust devils form when the surface of Mars heats up and causes warm air to rise rapidly, drawing dust particles into a spinning column. Dust devils can range in size from small, harmless whirlwinds to huge, kilometer-wide whirlwinds that can last for hours..
Dust devils help redistribute dust across the planet's surface, controlling its weather patterns and even the Martian climate.
This atmospheric phenomenon could be beneficial for spacecraft on Mars, but it could also pose a threat to them.. Dust devils can cause dust to accumulate on the surface of vehicles, but they can also carry it away.
Dust is especially harmful to solar panels on robotic vehicles because it reduces the amount of sunlight received needed to produce electricity..
As Focus already wrote, Elon Musk's Starship rocket defeats NASA in the space race. The world's most powerful rocket, created by SpaceX, is poised to cut the cost of space missions, leaving NASA behind..
Focus also wrote that, as scientists have found, one of the main components of the human body has been outside our galaxy for a long time. At the same time, it was created in the Milky Way, but then was thrown out of the galaxy.
