00:00Despite what it might be like at the moment, experts believe that Mars once had plenty of
00:08liquid water on it. Unfortunately, much of its atmosphere has been lost, and with that,
00:12a lot of its water. Maybe all of its liquid water was sucked out into space over billions of years.
00:17But now the Chinese Zurong rover has found crevices in the Martian surface,
00:21something that points to flowing water much more recently than anyone would have predicted.
00:25The cracks were found in the Barkan Dunes, part of the largest impact basin on Mars.
00:30Researchers say they mirror sand dunes on Earth, with giant deposits of Martian soil gathering into
00:35large wave-like hills. And also, just like areas like this on Earth, they noticed cracks in the crust,
00:40where on Earth they are formed when water from thawing snow rushed through the area.
00:44The same thing they believe happened here. However, they think it happened between 1.4 million
00:48and just 400,000 years ago. The crazy thing is that experts believe Mars had pretty much the
00:53exact same conditions back then as it does today. Meaning just like back then, when liquid water
00:58flowed to form these cracks, it's extremely likely it's still happening somewhere today.
01:03And where there's water, there's a good chance there could also be microbial life.
