SA/SPaH: Sample Acquisition, Processing, and Handling

Part of the Springer Praxis Books book series (PRAXIS)


Curiosity has unprecedented capability for interacting with the Martian surface using a collection of hardware called the Sample Acquisition, Processing, and Handling (SA/SPaH, pronounced “saw-spaw”) system (Figure 5.1). SA/SPaH includes the robotic arm and turret, the drill, and the sample scooping/sieving/portioning apparatus called Collection and Handling for In situ Martian Rock Analysis (CHIMRA, pronounced “chimera”). Also included in SA/SPaH are the Dust Removal Tool (DRT, but usually just called the “brush”), a variety of immobile hardware bolted to the front of the rover that supports sampling and drilling activities called the “sample playground,” and motorized inlet covers and spring-loaded wind guards for the SAM and CheMin instruments.
