In a landmark discovery published in Nature on September 3, researchers led by Prof. SUN Daoyuan and Prof. MAO Zhu from the University of Science and Technology of China, together with international collaborators, have provided the first seismic evidence for a solid inner core (IC) on Mars. By analyzing data from NASA’s InSight mission, the team estimated the Martian inner core’s radius to be about 600 kilometers and found it to be composed mainly of a crystallized iron-nicke

Mars dune with gullies in the Matara crater. The erratic course is probably due to disturbances such as wind ridges in the sand bed, sending the blocks in a different direction each time. Pits at the bottom of the slope mark the end of the process. Credit: Image taken by HiRISE (ESP_030528_1300_RED), NASA/JPL/University of Arizona. Did life really exist on Mars after all? Unfortunately, there is no conclusive evidence for this yet. Nevertheless, it would seem that some form o
