New Study Says Mars Wasn't That Wet, Not a Great Contender for Alien Life

March 15, 2024, 1:01 p.m. • The Debrief • (2 Minute Read)

In a recent study, researchers from Utrecht University in the Netherlands provide evidence that Mars may not have been as wet and potentially habitable as previously believed. The study suggests that the gullies on Mars, once thought to be formed by flowing water, could have been created by the sublimation of carbon dioxide (CO2) ice. The team conducted experiments simulating martian conditions, revealing that the CO2 sublimation process can cause sand to become fluidized and mobile, creating flow patterns similar to those seen in martian gullies. Climate modeling also supported this theory, suggesting that the gully activity observed on Mars could be explained by CO2 ice processes. These findings indicate that Mars may have been significantly more arid in its recent past, casting doubt on the possibility of sustained habitable conditions and reducing the likelihood of finding evidence of extraterrestrial life on the planet.
