Abstract
Sampling requirements for prospective landed extraterrestrial geological and biological instruments performing on-site analyses are satisfied by three general classes of samplers: bulk, selective particulate, and hard rock. Bulk samplers are noted as the type preferred by some, both for geological and biological experiments, but are more complex and require more processing steps than the simpler selective particulate samplers which reject oversize particulate material at the acquisition step. The steps required in sample acquisition and processing, and various methods of implementing them, are explained. Criteria for sampler selection are noted.
