Morning frost spotted on Mars where it was thought water frost impossible to exist

Morning frost has been spotted on volcanoes near Mars's equator for the first time, a part of the planet where it was thought impossible for water frost to exist. The “astonishing” discovery confirms that ice is not only confined to the red planet’s poles, and indicates that water ice is far more abundant across the planet than previously realised. The frost sits atop the Tharsis volcanoes - the tallest volcanoes not only on Mars, but across the Solar System.Source: PA
