NASA: Surprising evidence from Curiosity about Mars’ watery past – Watch video

The area’s sulfates are believed to have formed from the water gradually drying up

When NASA’s Curiosity rover arrived at the “sulphate-bearing planet” last fall, scientists were confronted with images they thought they had taken for granted. Images that reveal that lakes once covered this region of Mars.

Watch the video from Curiosity’s Mars exploration:

This is because the rocks here were formed in drier areas than those discovered and explored. The area’s sulfates are believed to have formed from the water gradually drying up.

So the Curiosity team was surprised to discover, through the mission, ancient water ripples on the ground formed by lakes. Billions of years ago, waves on the surface of a shallow lake that existed on the planet created wavy textures over time.

“This is the best evidence for water and waves that we’ve seen in the entire mission,” said Ashwin Vasavada, Curiosity mission scientist at NASA’s Jet Propulsion Laboratory in Southern California.
