This image from NASA's Curiosity rover shows the open inlet where powdered rock and soil samples will be funneled down for analysis. It was taken by the Mars Hand Lens Imager (MAHLI) on Curiosity's 36th Martian day, or sol, of operations on Mars (Sept. 11, 2012). MAHLI was about 8 inches (20 centimeters) away from the mouth of the Chemistry and Mineralogy (CheMin) instrument when it took the picture. The entrance of the funnel is about 1.4 inches (3.5 centimeters) in diameter. The mesh screen is about 2.3 inches (5.9 centimeters) deep. The mesh size is 0.04 inches (1 millimeter). Once the samples have gone down the funnel, CheMin will be shooting X-rays at the samples to identify and quantify the minerals.

Engineers and scientists use images like these to check out Curiosity's instruments. This image is a composite of eight MAHLI pictures acquired at different focus positions and merged onboard the instrument before transmission to Earth; this is the first time the MAHLI performed this technique since arriving at Curiosity's field site inside Gale Crater. The image also shows angular and rounded pebbles and sand that were deposited on the rover deck during landing on Aug. 5, 2012 PDT (Aug. 6, 2012 EDT).
