Scientists have discovered frost on Mars' Olympus Mons volcano, indicating a sparse yet active water cycle on the Red Planet. This phenomenon challenges previous assumptions about frost formation near Mars' equator due to its thin atmosphere and intense sunlight. Using data from Mars orbiters, researchers found that frost forms briefly each morning during colder seasons in the Tharsis volcanic region. This finding, involving meticulous analysis spanning five years, suggests a unique water activity cycle on Mars with implications for future exploration missions.
