The SuperCam Instrument Suite on the Mars 2020 Rover: Science Objectives and Mast-Unit Description

Abstract On the NASA 2020 rover mission to Jezero crater, remote determination of texture, mineralogy and chemistry rocks is essential quickly thoroughly characterize an area optimize selection samples for return Earth. As part Perseverance payload, SuperCam a suite five techniques that provide critical complementary observations via Laser-Induced Breakdown Spectroscopy (LIBS), Time-Resolved Raman Luminescence (TRR/L), visible near-infrared spectroscopy (VISIR), high-resolution color imaging (RMI), acoustic recording (MIC). operates at distances, primarily 2–7 m, while providing data sub-mm mm scales. We report on SuperCam’s science objectives in context Mars goals ways different can address these questions. The instrument made up three separate subsystems: Mast Unit designed built France; Body provided by United States; calibration target holder contributed Spain, targets themselves entire team. This publication focuses design, development, tests Unit; companion papers describe other units. goal this work understanding technical choices made, constraints were imposed, ultimately validated performance flight model as it leaves Earth, will serve foundation operations future processing data.
