New model reveals Venus's crust thinner than expected

• The new geological model of Venus suggests its crust is thinner than previously believed.
• Venus's crust shows no signs of subduction, distinguishing it from Earth.
• Planned space missions are set to verify the scientists' theories.

NASA scientists have developed a new geological model of Venus that suggests its crust might be significantly thinner than previously believed. According to researchers, the average crust thickness is approximately 25 miles, with a maximum reaching 40 miles. This discovery could alter our understanding of geological processes on this planet.

Unlike Earth, where the crust consists of moving tectonic plates, Venus shows no signs of subduction—a process where one tectonic plate slides under another. On Earth, this process controls crust thickness, but on Venus, the lack of plate motion means geological processes occur differently.

Justin Filibert from NASA indicates that the detachment or melting of the lower crust might supply water and elements to the planet's interior, which stimulates volcanic activity. This new model might explain the formation of lava and volcanic eruptions on Venus.

Scientists will have to wait to verify the latest theory. Probes launched to Venus might confirm or refute it. Among the planned missions are the American DAVINCI and VERITAS missions, as well as the European EnVision. Their launches are planned for 2030 and 2031. Scientists hope they will gather more precise data.

Anticipated space missions might provide crucial information that will allow for a better understanding of Venus's geology. The results of these studies could be of significant importance to planetary science and help discover new geological mechanisms.
