Engineers at NASA's Jet Propulsion Laboratory performed tests on rocks such as this one to understand why the first attempt by the agency's Perseverance rover resulted in a powderized sample. A duplicate of the rover's drill attempted to create cores from crumbly rocks. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life.
