On Mars, Curiosity Rover Discovers a “Paradise of Polygons”

An express mission to capture spectacular images of March

A few days ago, the rover was sent on a mission to photograph the famous polygons that were formed on Martian soil. It was a mission “touch and go”, that is to say that the rover stops briefly at a precise location.

He can observe and analyze the environment using his scientific instruments such as the Mahli camera (Mars Hand Lens Imager) and the Chemcam spectrophotometer. The particularity of these missions is that they do not last long, generally a few hours.

The rover resumes its way the same day, even the next day. These Touch and Go missions are particularly useful for optimizing Curiosity resources while sampling as many sites of scientific interest.

A promising geological site to understand the past of Mars

This recent rover mission was no exception. Curiosity stopped for a few hours to study the land fractured in a polygonal way. The images were photographed on May 4, 2025 or Sol 4530 which corresponds to 4,530^e Martian day since the landing of rover.

NASA describes this site as “polygons paradise”. He could even reveal precious climbs on the climate history of Mars. In addition to the images photographed by the Mahli camera, the rover also used its spectrophotometer to analyze a rocky vein 30 cm long.

At present, we do not yet know the origin of these mysterious polygonal forms on the Martian surface. They could nevertheless constitute a “another index on the way in which Mars lost its water and when”, according to the American space agency.

Where do these mysterious polygons of the Martian surface come from?

Several theories have been put forward by scientists to date. For example, the planetary geologist Catherine O'Connell-Cooper (University of New Brunswick) thinks that these structures could have formed billions of years as the planet was hung.

Another theory is that these cracks would have appeared later. Their training would have been caused by the circulation of groundwater below the surface of Mars. These patterns are also reminiscent of those that can be observed on earth when the mud drips.

Each discovery brings Curiosity closer to its main mission

Be that as it may, these Martian cracks form spectacular polygonal patterns. In -depth research is necessary to determine the most likely origin of these reasons.

Let us not forget that the main mission of the Rover Curiosity is to seek traces of an ancient life on Mars. Each new discovery therefore allows us to decipher the red planet more.
