Article: « Les traces insoupçonnées d’une ancienne activité tectonique sur Mars »

Response:
According to the article, researchers have discovered evidence of an ancient tectonic activity on Mars. The study, published in the journal Nature Communications, analyzed images taken by the High Resolution Stereo Camera on board the European Space Agency’s Mars Express spacecraft. The researchers identified a series of fault scarps, which are cliff-like landforms that form as a result of tectonic activity. The scarps were found in the southern highlands of Mars and are estimated to be around 2 to 4 billion years old. This discovery suggests that Mars may have had a more active geological history than previously thought.
