    Oct 18, 2016 · The young planet Mars would have had enough water to cover its entire surface in a liquid layer about 140-meters deep. But it is more likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 kilometres. ESO/M. Kornmesser.

    2 days ago · “Glaciers aren’t ice cubes, sitting there to waste away. In order to have glaciers, you have to have precipitation. Water has to move through the atmosphere, and it precipitates and makes the ice grow.” And glaciers don’t form in the coldest environments, he added. Glaciers form where there is cold and moisture.

    The water returns to the ground at lower latitudes as deposits of frost or snow mixed generously with dust. The atmosphere of Mars contains a great deal of fine dust particles.[203] Water vapor condenses on the particles, then they fall down to the ground due to the additional weight of the water coating.

    1 day ago · New findings from ’s Mars Reconnaissance Orbiter () provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on , researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow ...

    Oct 16, 2006 · Launched on 2 June 2003, Mars Express has changed the way we think of Mars. Since the Viking missions of the 1970s, planetary scientists have changed their perception of water on Mars several times, passing from the picture of a dry planet to that of a warmer and wetter one. Mars Express's data are now shedding a new light on the complex issue ...

    Oct 25, 2022 · Just like Earth, Mars likely got its water from asteroids and comets that bombarded its surface. Conditions may have been right for the red planet to be habitable from 4.1 to 3 billion years ago. During that time, life could have taken hold in global oceans, rivers, and lakes. Liquid water may have flowed even longer, up until about 2 billion ...

    Jul 25, 2018 · Landforms such as dry river valleys and lakes show that liquid water must have been present on Mars in the past (1). Nowadays, small amounts of gaseous water exist in the martian atmosphere, and some water ice is found on the planet's surface. Water droplets were seen condensing onto the Phoenix lander (2), and there may be reoccurring water ...
