Photograph records 19km dust cloud on Mars
An experiment by the University of Arizona was able to record high-definition images of a dust cloud over 19 kilometers above the surface of Mars. The exact size of the phenomenon was measured from the angle and intensity of the shadow it cast as it moved.
Although sand clouds are common phenomena on Earth, especially in desert regions, no such event occurs in such large proportions on our planet. Even tornadoes, whose characteristics are much more violent and intense, reach an average height of 16 kilometers. If Mars has enough water to generate such an event, it is frightening just to think of the dimensions it could reach.
The good news is that, despite the large size of the Martian dust cloud, it would not be too dangerous for human astronauts due to the planet's low atmosphere density - as there is not much air to displace, the phenomenon would probably not even have the necessary force. to bring down a person.
