Rover team members Kim Lichtenberg (left) and Mike Seibert fill a mixer with powdered clay and diatomaceous earth, a combination found to offer physical properties similar to the soil where NASA's Mars Exploration Rover Spirit is embedded on Mars. The team finished mixing the test soil and preparing a sloped testing area on June 29, 2009, with plans for driving the test rover into it on June 30.
