    Oct 18, 2016 · Right now, the surface of Mars is now extremely arid because the air is too thin for liquid water to last for long. The red planet’s atmospheric pressure is just roughly 1/100th of Earth’s and in such thin air water easily boils. However, dark, narrow lines on martian slopes hint that water could run downthese formations regularly.

    In 2020 scientists reported that Mars' current loss of atomic hydrogen from water is largely driven by seasonal processes and dust storms that transport water directly to the upper atmosphere and that this has influenced the planet's climate likely during the last 1 Ga. [309] [310] More recent studies have suggested that upward propagating atmospheric gravity waves can play an important role ...

    Jan 26, 2022 · Not only did they offer evidence that Mars had been much wetter long ago, they also offered a way to date the last time that water had existed in liquid form on the planet’s surface. “Salt is incredibly soluble, so any moisture at all would dissolve it,” said Ellen Leask, lead author of a paper examining the deposits that was published by the journal AGU Advances on Dec. 27.

    Jan 26, 2022 · But two scientists studying data that MRO has accumulated at Mars over the last 15 years have found evidence that reduces that timeline significantly: Their research reveals signs of liquid water on the Red Planet as recently as 2 billion to 2.5 billion years ago, meaning water flowed there about a billion years longer than previous estimates.

    2 days ago · Scientists have known for decades that Mars, at least in its ancient past, has had a considerable amount of water. But when Mars Global Surveyor began mapping the Red Planet in sharp detail early in 1999, it disclosed startling evidence that water has shaped Martian landforms within the past 10 million years.
