Chile's Atacama Desert is the most Mars-like place on Earth. NASA tested the new drill, which can dig soil samples from the depths of the surface, and then other tools on the roam will analyze the samples to find possible life on Mars. Testing in Chile's Atacama desert is important for drills and rovers to prepare for Mars. NASA wants to know if there has been life on Mars. Mars is known to have had a denser and wetter atmosphere in its distant past.
Scientists have concluded that Mars has had oceans and found evidence of the existence of water on the surface of Mars, but NASA wants to know if there is life in the water. Today, the surface of Mars has a thousand times less water than the driest part of the Atakama Desert, one of the driest places on Earth.
