Curiosity has a sophisticated sample handling and preparation system, known as the Sample Acquisition/Sample Processing and Handling (SA/SPaH, “saw-spa”) system. SA/SPaH has the ability to divide a drilled or scooped sample up into different ranges of particle sizes. In the case of the Ogunquit Beach sample, the finest particle size range corresponded to the material that was delivered to both SAM and CheMin. It is known as the post-sieve sample. The larger particle size range material, which was just along for the ride within SA/SPaH, is known as the pre-sieve sample. The first round of MAHLI imaging of both the pre-sieve and post-sieve samples, dumped into… [More at link]
