Perseverance's Mastcam-Z instrument provides high-resolution stereo and multispectral images with a unique combination of spatial resolution, coverage, wavelength coverage along the rover's traverse in Jezero crater, Mars. Images reveal rocks consistent an igneous (including volcanic and/or volcaniclastic) impactite origin limited aqueous alteration, including polygonally fractured weathered coatings; massive boulder-forming bedrock consisting mafic silicates, ferric oxides, iron-bearing...
Abstract The Mastcam-Z Camera is a stereoscopic, multispectral camera with zoom capability on NASA’s Mars-2020 Perseverance rover. relies set of two deck-mounted radiometric calibration targets to validate performance and provide an instantaneous estimate local irradiance allow conversion image data units reflectance (R ∗ or I/F) tactical timescale. Here, we describe the heritage, design, optical characterization these discuss their use during rover operations. primary target inherits...
Abstract The Planetary Instrument for X-ray Lithochemistry (PIXL) onboard the Perseverance rover, part of NASA’s Mars 2020 mission, has first camera system that utilizes active light sources to generate multispectral data directly on a planetary surface. PIXL collects using three different components in Optical Fiducial System (OFS): Micro Context Camera (MCC), Floodlight Illuminator (FLI), and Structure illuminator (SLI). MCC captures images illuminated at wavelengths by FLI while...
The Terminal Tracking Camera (TTCam) imaging system on the NASA Lucy Discovery mission consists of a pair cameras that will be used mainly as navigation and target acquisition for mission’s asteroid encounters. However, secondary science-focused function TTCam is to provide wide-angle broadband images over large range phase angles around close approach during each flyby. scientific data acquired by can shape modeling topographic geologic analyses. This paper describes pre-flight initial...
