Water Frost Discovered on Martian Volcanoes

Researchers find transient morning frost on the tallest volcanoes near Mars' equator, challenging previous assumptions about the planet's climate.

Frost was detected on Olympus Mons, the tallest volcano in the solar system, and three other volcanoes.
The frost forms in the early morning and evaporates quickly due to sunlight.
This discovery was made using high-resolution images from ESA's Trace Gas Orbiter and Mars Express missions.
The frost is extremely thin but covers a large area, equivalent to 60 Olympic swimming pools of water.
The findings could enhance understanding of Mars' water cycle and aid future exploration missions.
