NASA's ongoing quest to 'follow the water,' in hopes of finding hints of life on Mars, has uncovered seasonally-appearing dark streaks that researchers call 'the best evidence we have to date of liquid water occurring today' - that is, not in the ancient past - 'on Mars.'Spotts, Pete...
"When most people talk about water on Mars, they're usually talking about ancient water or frozen water," he said. "Now we know there's more to the story. This is the first spectral detection that unambiguously supports our liquid water-formation hypotheses for RSL."...
The presence of liquid water on Mars has long been a topic of interest, as it has significant implications for interstellar migration and understanding the evolution of the Martian climate. The presence of liquid water could indicate a habitable environment on Mars and potentially even the existence...
Recent liquid water flow on Mars has been proposed based on geomorphological features, such as gullies. Recurring slope lineae — seasonal flows that are darker than their surroundings — are candidate locations for seeping liquid water on Mars today, but their formation mechanism remains unclear. To...

Today's findings seem to offer more direct evidence of liquid water than most, though the study only confirms what NASA has long suspected— that flowing liquid water forms the strange, dark streaks that have been observed on Mars. These streaks — called recurring slope lineae — were first ...
Today, Mars is a frozen desert with a thin atmosphere, too cold for liquid water to remain on the surface. Overwhelming evidence exists that Mars had liquid water oceans roughly 4 billion years ago. The question that drives our interests isn’t whether there’s life on present-day Mars. We...
Liquid Water “Lake" Revealedon Mars火星上发现液态水体Since NASA's Viking Mission tested Martian soil samples back in the 1970s, we'veknown the surface of Mars to be a desert—inhospitable to life as we know it. But asmissions to Mars focused on what lies beneath the surface, a different...
"It suggests that it would be possible for life to be on Mars today," John Grunsfeld, NASA's associate administration for science, told reporters. "Mars is not the dry, arid planet that we thought of in the past. Under certain circumstances, liquid water has been found on Mars," said ...
This book provides an overview of the discovery of liquid water on Mars and the physical and geochemical processes that cause liquid saline water to form and stabilize in cold and dry environments such as the shallow martian subsurface and some areas of the polar region. The book also analyzes...
