The most recent European satellite in Mars has identified the landing site of the American-led InSight probe.

The Nasa spacecraft landed in November on flat land near the equator in a region called Elysium Planitia.

The European-Russian triad Trace Gas Orbiter (TGO) then moved into the head in March to capture the scene.

Visible in the image of the TSS CaSSIS camera are the lander and the elements that brought it to the ground safely.

These components include the parachute and the two halves of the capsule that protected InSight during its fiery descent through the atmosphere – its heat shield and its back shell.

Something else that can be seen are the burn marks around the probe that were made by the rocket engines of the aircraft as it gently lays on the surface of Mars.

The image is one of the series of images just released by the CaSSIS team (Color and Stereo Surface Imaging System) on the TGO mission . [19659009] The instrument of the Swiss group acquires stereo images of the planet's surface at the best resolution of 4.5 m per pixel.

It is mainly based on providing a visual context for the other instruments of the orbiter that are trying to track down positions on Mars where methane and other trace gases could be released into the atmosphere.

But when CaSSIS is not doing this work in tandem, it is used as an imager for the study of the geology of the planet.

A good example is the image of the floor of the Kibuye crater in the Terra Sirenum region, says prof. Nic Thomas of the University of Bern.

"These places where you have a lot of color diversity indicate a great diversity of minerals and in different layers. This means that we could look at sedimentary layers where the deposition from the water was a key process and since CaSSIS has this "Color and stereo capabilities, people are really trying to use the camera on these sites," he told BBC News.

The stereo allows scientists of ld elevation models and calculate the thick area of ​​the layers.

The crater to the left of this image is called Jezero. It is here that NASA will send a rover in 2020 . This is a red-blue stereo image that is best displayed with "3D" glasses

The Trace Gas Orbiter has been in its scientific orbit around Mars for almost a year.

its role is to provide a communication relay for surface operations.

The Insight probe of the American space agency and its Curiosity rover will talk to the Earth through the TGO.

And when the Russian-Russian joint rover Rosalind Franklin arrives in 2021, he will also use the orbit to transfer his data home.

This mysterious pattern was depicted on the crest of a ridge in the Terra Sabaea region on Mars. The lines are meant to be the traces left by hundreds or maybe even thousands of "dust devils", Martian mini tornadoes. The false blue color is used for the contrast
