the JSC Mars-1 sample consists of weathered volcanic ash from the Pu'u Nene cinder cone on the Island of Hawaii (USA). The original sample was sieved (200 µm sieve). Part of the sample was heated up to 200C for 24 hours to get rid of the volatile components. The heated sample is called JSC200, whereas the non-heated is JSC0
