New Rover Could Seek Evidence of Ancient Mars Life Just Below Surface: Study
Evidence of ancient life on Mars, if any such evidence exists, might be detectable at shallower depths below the planet’s surface than has been thought, a new study says – which would improve the chances that NASA’s newest Mars rover, scheduled to touch down on the Red Planet next month, finds it.
The research indicates that simple organic molecules, such as a single molecule of formaldehyde, could exist a mere 2 to 4 inches (5 to 10 centimeters) beneath the Martian surface. While the radiation level at these depths is still intense, simple building blocks of life (and, in the case of young craters, perhaps even complex building blocks) could survive, the researchers said.
