Some of these impacts are catastrophic, but others leave relatively small craters that are tricky for even the most keen-eyed scientists to spot.⁠ ⁠ For the first time ever, a machine learning tool has discovered this type of subtle crater formation on Mars, according to NASA’s Jet Propulsion Laboratory. The AI tool, which is called “an automated fresh impact crater classifier,” found a previously unknown cluster of Martian craters in images captured by NASA’s Mars Reconnaissance Orbiter. The new detection indicates that there might be a whole host of craters on Mars that we currently can’t see.⁠ ⁠ Link in bio for more. ⁠ ⁠ 📸: NASA/JPL-Caltech/University of Arizona⁠」10月8日 23時55分
