The Embry-Riddle Aeronautical University (ERAU) Spacesuit Utilization of Innovative Technology Laboratory (S.U.I.T. Lab) specializes in spacesuit operations, testing, and analysis, with a focus on human performance. The lab works to involve students from all disciplines in human spaceflight research. A majority of the lab’s students are studying Spaceflight Operations, Aerospace Engineering, or Human Factors. This proposal, created by undergraduate students at ERAU, seeks to describe the capabilities of the Photo Reference and Identification Sample Marker(PRISM). PRISM is designed as a sample size, color, and location calibration marker for use during lunar surface extravehicular activities (EVAs). This application requires ease of use for astronauts wearing the Exploration Extravehicular Mobility Unit (xEMU) spacesuit, as well as reliability in the lunar dust environment. PRISM can either be configured vertically or horizontally depending on the sample site. The device consists of an outer casing and a slider subassembly. The casing features reference markers for identification and calibration on the exterior. The slider subassembly includes a slider block which is used to deploy the legs for a vertical configuration. There are additional reference markers along the legs, and they can easily be extended to be stable on inclined terrain. PRISM can also simply be placed on surfaces horizontally without deploying the legs if desired. PRISM is a versatile, easy to use, and dust tolerant device designed to streamline science operations on the lunar surface
