As noted by Semana, a question remains: until when did Mars manage to preserve liquid water on its surface, especially considering the evidence of ripple formation around 3.7 billion years ago, a period when Mars was thought to be becoming drier. Researchers estimated that these wave ripples dat...
Was There Water on Ancient Mars? Despite Mars's bleak,cold climate today,there is abundant geologic evidence that liquid water once flowed on the Martian surface (and even recent evidence that some water still periodically flows today).The evidence of past flows includes river channels,now dry,...
It was already known that there must have been water onMars, but now the first evidence of rivers in long-term action preserved in exposed cliff faces has been found. “Rivers that continuously shifted their gullies, creating sandbanks, similar to the Rhine or the rivers that you can find ...
The structure, thickness, and length of the section supported voluminous supply of onshore sediments into a large body of water, rather than a merely localized and short-lived melt event, the article noted. Such findings support the existence of an ancient Martian ocean in the northern plains ...
Researchers have spent decades looking for evidence of ancient water onMars. As technology has progressed, more evidence has come to light that rivers, lakes, and even oceans were once abundant on the red planet. Modern Mars is icy and dusty and unlikely to have much liquid water on the sur...
Analysis of the images has shown the water carved out thecanyon1in which it was found, which then opened out into a valley depositingsediment2which formed adelta3. "Finding shorelines is a holy grail of sorts to us," said assistant professor Brian Hynek, adding it showed the lake existed...
Despite Mars's bleak,cold climate today,there is abundant geologic evidence that liquid water once flowed on the Martian surface (and even recent evidence that some water still periodically flows today).The evidence of past flows includes river channels,now dry,that were once carved by powerful ...
Those layers provide unmistakable evidence that soil sediments carried by water were deposited at Jerezo Crater and its delta from a river that fed it, just as they are in lakes on Earth. The findings reinforced what previous studies have long suggested - that cold, arid, lifeless Mars was ...
The mounds are near the future landing site of theESA’s ExoMars Rosalind Franklin rover, expected to launch in 2028. There is a chance the mounds could be investigated by the rover, which may reveal more about the history of water on the red planet and pinpoint resources for...
