Mars Rover Finds Stronger Potential for Life

In its search for environments where life might have started on Mars, the Curiosity rover has found the standing water, the energy and the key elements with the right atomic charges. As a result, scientists have concluded that at least some of the planet must have been habitable long ago. But the period when all conditions were right was counted in hundreds to thousands of years, a very small opening by origin-of-life standards.
