Mars missions may benefit from sample acquisition systems under development that are capable of acquiring samples from the surface, from a few centimeters below the surface, from one meter below the surface and from ten meters or more below the surface.The Sample Acquisition and Transfer Mechanism (SATM) is a highly developed sampling tool that features interfaces with in-situ science instruments and sample return containers. A prototype SATM has been developed and successfully tested at Honeybee Robotics to demonstrate the performance requirements necessary to meet the ST/4 Champollion mission goals., many of which could be applicable to a Mars sampling mission. The SATM has been designed to: (1) acquire surface samples, samples at 20 centimeters below the surface and samples at one meter (or more) below the surface, without cross contamination. To accommodate the different sample volume requirements by each instrument, the SATM is also designed with a sample chamber that can be infinitely adjusted from 0.1 cc to 1.0 cc. A newer version of SATM is being planned for development in FY01 in collaboration with the JPL Exploration Technology program, where the sample volume will be increased to a maximum of 50.0 cc. This new SATM will also be capable of taking a core sample; (2) transport and transfer samples to a microscope/IR spectrometer, chemical analysis ovens, and a sample return container. For the microscope, the SATM features a sapphire window through which the samples in the chamber can be presented for analysis.
