00:00Mars Jezero Crater experienced at least three separate episodes of water activity,
00:04not just one ancient lake event as once thought.
00:07NASA's Perseverance rover found igneous rocks altered by groundwater,
00:12lake water, and heated fluids beneath the surface.
00:15These rocks contain minerals like carbonate and silica,
00:18which on Earth can preserve signs of ancient microbial life.
00:21The rover's SuperCam instrument analyzed more than 185 rock targets,
00:26revealing a complex history where magma cooled underground before water changed the rock chemistry.
00:32Mars constantly throws surprises at you, said Candice Bedford,
00:36lead author and research scientist,
00:39highlighting how these findings reshape our understanding of Mars' watery past.
