Curiosity has found evidence that the 96-mile-wide (154 kilometers) Gale Crater, which the rover has been studying since August 2012, hosted a large lake long ago. Runoff into this lake eventually built up Mount Sharp, mission scientists say.
08 December 2014, 02:11 PM ET
Data from NASA's Curiosity rover indicates that lake bottom sediment formed the lower layers of Mount Sharp over approximately 1 million years.

Humanity can dramatically reduce its frightening vulnerability to cataclysmic asteroid strikes with just a little extra funding and a little extra effort, say the organizers of the "Asteroid Day" educational campaign.
03 December 2014, 03:51 PM ET
Intense volcanic activity could have spewed tons of greenhouse gases into the Martian atmosphere, warming the Red Planet enough for water to flow billions of years ago.
