Curiosity Rover Hits Paydirt on Mars | NASA Planetary Sciences

Learn about the discovery of conditions that would have been suitable for life on ancient Mars. In 2013, the Mars Science Laboratory (MSL) science team released initial findings from its first drilled sample using the Curiosity rover. MSL scientist Joel Hurowitz describes the sedimentary rock sample from the "John Klein" site, which showed that the rock was deposited in a freshwater environment and contained carbon, sulfur, and oxygen -- key ingredients for life. Earlier missions to Mars had found evidence of acidic and salty watery environments that would not have been favorable for life.
