0:00.0	Hi, we've got three stories from curiosity.com to help you get smarter in just a few minutes.
0:05.6	I'm Cody Gough.
0:06.4	And I'm Ashley Hamer.
0:07.5	Today you'll learn about how we may have detected liquid water on Mars
0:11.0	and what's next for exploring the red Planet, a long lost gold mine that might
0:14.8	exist in the Arizona mountain, and how you can sharpen your memory with the Zagarnik effect.
0:19.4	Let's set us for some curiosity.
0:21.2	We've got big news to start off today. If you haven't heard, we may
0:24.6	have detected liquid water on Mars. Radar observations from the Mars Express
0:28.8	spacecraft suggest a 12 and a half mile zone of sediments with water in the South Polar region.
0:34.0	For some background, there is definitely water on Mars already.
0:38.0	There are layers of water ice and sometimes carbon dioxide ice that wax in wane with the seasons on Mars.
0:44.0	But we've never found running water where microbes might like to live.
0:48.0	Scientists think Mars used to be a lot wetter than it is today.
0:51.0	That's based on the canyons and certain rocks on the surface like
0:54.2	hematite which usually form in water. The theory is that the red planet's
0:58.5	atmosphere slowly eroded away because Mars doesn't have a global magnetic field so it didn't have a lot of protection from the it
1:03.0	because Mars doesn't have a global magnetic field, so it didn't have a lot of protection from the sun's radiation.
1:06.0	Now, not all scientists agree that this water reservoir is there.
1:10.0	But if it is, then it's probably a leftover of that wetter period on Mars billions of years ago.
1:15.5	And to be clear, the science team specifically said sediments mixed with water, not a lake, like some media
1:21.4	outlets have been reporting.
