The characteristic of Mars, which looks like a very hairy spider, is probably due to the convergence of hundreds or thousands of tornadoes.

David Bowie sang about a sci-fi scientist, Ziggy Stardust, performing with a spider on Mars, and eventually a "spider" appears on Mars.
The images captured by the European Space Agency (ESA) satellite seemed like a very hairy blue spider that recently extended the "legs" across the Mars landscape.
However, an ESA official said in a statement yesterday (March 14) that the so-called "spider" has formed a massive tornado, and that there is a ridge left over because of dust particles. [Seeing Things on Mars: A History of Martian Illusions]
ESA-Roscosmos ExoMars tracking gas satellites captured images on February 8th in the Terra Sabea region of Mars using color and stereo surface imaging system (CaSSIS). The blue orbit represents part of the ridge scratched and polished by the wind of the tornado. The actual color of the material exposed by the tornado is dark red, but it appears blue in the color composite image; This technology improves the contrast of surface properties.
An ESA spokesperson said it was not known why so many dust devils (or dust tornadoes) converged along the ridge, although local mountains might affect airflow and contribute to the formation of tornadoes.
The ExoMars orbital launched in 2016 captured a photo of NASA's InSight lander on March 2 and struck a "mole" gauge to dig into the floor to sample the interior of Mars. In the image, InSight appears as a small white dot in a dark dark circle that is blackened by the rocket's rocket during touchdown. Inside the heat shield and parachute are nearby.
Other photos of ESA released yesterday feature an incredibly well-preserved crash crater. Layer deposits near the polar ice cap on the south side of Mars; 3D view of craters, hills and outcrops.
Nicolas Thomas, senior investigator at the University of Berns in Switzerland (CaSSIS), commented, "All the images we share have been the best in the last few months.
The "hairy spider" is not the first rogue picture of the Martians. In 1976 NASA's Viking 1 spacecraft captured an image of a mountain resembling a human face very much on Mars, and a curiosity probe captured images of mice, lizards, and floating spoons. It turns out to be a strange shaped rock.
