A recent study conducted by researchers at Penn State University indicates that numerous craters on Mars may have once been flowing rivers, raising the possibility of ancient habitable conditions on the Red Planet. The findings were based on an in-depth analysis of data collected by NASA’s Curiosity rover.
Lead author Benjamin Cardenas, an assistant professor of geosciences at Penn State, stated, “We’re finding evidence that Mars was likely a planet of rivers. We see signs of this all over the planet.” The study, published in Geophysical Research Letters, employed numerical models to simulate erosion on Mars over extended periods, revealing that the bench-and-nose landforms observed in various craters were likely remnants of ancient riverbeds.
This groundbreaking study utilized a combination of satellite data, Curiosity rover images, and 3D scans of rock layers beneath the Gulf of Mexico seafloor. By training a computer model on this data, the researchers identified a new interpretation for common Martian crater formations. Previously unrecognized eroded river deposits were discovered, contradicting past studies that primarily focused on fluvial ridges.
Cardenas elaborated, “This suggests that there could be undiscovered river deposits elsewhere on the planet, and that an even larger section of the Martian sedimentary record could have been built by rivers during a habitable period of Mars’ history.”
The team’s computer model, designed using scans of Earth’s stratigraphy obtained from beneath the Gulf of Mexico seafloor, revealed erosional Martian landscapes similar to those observed by the Curiosity rover. This exciting discovery opens up the possibility of Mars having had far more rivers than previously believed, providing a more optimistic view of ancient life on the planet.
Cardenas emphasized, “Our research indicates that Mars could have had the right conditions for life in most of its regions. It offers a vision of Mars where most of the planet once had the right conditions for life.”
Co-author Kaitlyn Stacey, a doctoral candidate in planetary geosciences at Penn State, contributed to this groundbreaking study. The research was funded by a NASA Solar System Workings Grant.
As exploration of Mars continues, these findings bring scientists closer to unraveling the mysteries of the planet’s past and offer valuable insights into the potential existence of ancient life on Mars. The discovery of these ancient riverbeds suggests that Mars was once a more hospitable world, raising excitement about the possibility of finding conclusive evidence of life on our neighboring planet.
