Sample acquisition, processing and handling systems for future Mars missions

The next generation of Mars exploration robotics will have equipment to acquire subsurface samples, process and refine them, and transfer them to science instruments for observation. In 2003, MD Robotics and NORCAT, under contract with the Canadian Space Agency, designed, developed and tested building block technologies for a sample acquisition, processing and handling system for a future Mars mission. Four key technologies were developed to support this system: drill bit development for varied substrates, sample acquisition mechanisms to acquire cores at depth, material transport technologies to move waste material up the hole, and sample reduction technologies, studying the means to efficiently reduce samples into uniform particle sizes. This paper will discuss the technology development, the driving requirements and the test results.
