NASA's Mars rover Curiosity has discovered complex chemistry on the Red Planet, as well as hints of long-sought organic compounds that could aid primitive life, scientists announced today (Dec. 3).
The Curiosity rover found evidence of chlorine, sulfur and water in Mars dirt studied by its onboard laboratory, as well as organic compounds (chemicals containing carbon) inside its Sample Analysis at Mars instrument. However, the science team can't yet be sure whether these compounds truly come from Mars, or arise from contamination transported to the Red Planet onboard Curiosity.
