NASA has announced that it is testing a new tool that may one day head to Mars to help with the search for life on the Red Planet. The tool is attached to a rover being tested in the Atacama Desert in Chile called ARADS. The tool being tested is a drill that is meant to dig deep under the surface of Mars. ARADS stands for Atacama Rover Astrobiology Drilling Studies, and it is testing in the Atacama desert because the location is the most Mars-like place on Earth. The new drill is a tool that will dig up soil samples from deep inside the planet that other tools on the rover will analyze in a search for life. The drill was developed in partnership with Honeybee Robotics. The project in the desert here on Earth is important to get the drill and tools ready to one day head to Mars. NASA wants to know if there was once life on Mars. The planet is known to have had a denser and wetter atmosphere in its distant past. The planet once had oceans of water, and while evidence of water on its surface has been found, NASA wants to know if that water harbored life. Today the surface of Mars has a thousand times less water than the driest parts of the Atacama desert, which is one of the driest...
