This image shows an experiment conducted at NASA's Jet Propulsion Laboratory re-creating the processes that form spider-like features on Mars called araneiform terrain. The experiment involves carbon dioxide gas settling into Mars soil simulant. The gas settles between the grains of simulant and eventually freezes into ice. A heater underneath the soil simulant then warms up the ice and turns it back into gas. As pressure from the gas builds, the frozen top layer of simulant eventually cracks. When the pressure builds enough, a plume of carbon dioxide erupts. The study confirms…
