The same mechanism that gives Mars its cliffs and canyons could also give it subsurface life.

00:00 When picturing alien life on Mars, what comes to mind is likely bacteria or simple organisms
00:08 clinging to life on the surface of the Red Planet.
00:10 But now experts are saying that a better place to look for it might be under the Martian
00:14 surface.
00:15 According to researchers for the Search for Extraterrestrial Intelligence Institute, or
00:19 SETI in California, there's ice that is melting under the Martian surface.
00:23 But how do we know that and why is it important?
00:25 Well the researchers believe that subsurface ice is melting and mixing with permafrost,
00:29 creating unstable terrain that's causing landslides.
00:32 Those landslides, which the researchers say can travel at around 225 miles per hour, are
00:37 thought to be the reason for the trenches and cliffs on the Red Planet.
00:40 And we can see those.
00:41 And of course water is crucial for the survival of life, meaning water under the surface could
00:45 mean life is down there as well.
00:47 In an environment some say might be much like that of Antarctica, so how does ice melt on
00:51 Sub-Zero Mars?
00:52 The answer is salts.
00:54 In a lab, researchers recreated Martian temperatures and conducted a study on regolith-like substances
00:58 made of chlorine, salt, and sulfates, finding that a slushy water mixture could be produced
01:03 even in temperatures of down to minus 58 degrees Fahrenheit.
