The Pancam Instrument for the Exomars Rover
ASTROBIOLOGY ExoMars Rover Mission Volume 17, Numbers 6 and 7, 2017 Mary Ann Liebert, Inc. DOI: 10.1089/ast.2016.1548 The PanCam Instrument for the ExoMars Rover A.J. Coates,1,2 R. Jaumann,3 A.D. Griffiths,1,2 C.E. Leff,1,2 N. Schmitz,3 J.-L. Josset,4 G. Paar,5 M. Gunn,6 E. Hauber,3 C.R. Cousins,7 R.E. Cross,6 P. Grindrod,2,8 J.C. Bridges,9 M. Balme,10 S. Gupta,11 I.A. Crawford,2,8 P. Irwin,12 R. Stabbins,1,2 D. Tirsch,3 J.L. Vago,13 T. Theodorou,1,2 M. Caballo-Perucha,5 G.R. Osinski,14 and the PanCam Team Abstract The scientific objectives of the ExoMars rover are designed to answer several key questions in the search for life on Mars. In particular, the unique subsurface drill will address some of these, such as the possible existence and stability of subsurface organics. PanCam will establish the surface geological and morphological context for the mission, working in collaboration with other context instruments. Here, we describe the PanCam scientific objectives in geology, atmospheric science, and 3-D vision. We discuss the design of PanCam, which includes a stereo pair of Wide Angle Cameras (WACs), each of which has an 11-position filter wheel and a High Resolution Camera (HRC) for high-resolution investigations of rock texture at a distance. The cameras and electronics are housed in an optical bench that provides the mechanical interface to the rover mast and a planetary protection barrier. -

Sletten3, and the MSL Science Team. 1Jet Propulsion Labora- tory, California Inst of Technology ([email protected]), 2Malin Space Science Systems, San Diego, CA ([email protected] ), 3University of Washington, Seattle. Introduction: Localization is a process by which tactical updates are made to a mobile lander’s position on a planetary surface, and is used to aid in traverse and science investigation planning and very high- resolution map compilation. “Contextualization” is hereby defined as placement of localization infor- mation into a local, regional, and global context, by accurately localizing a landed vehicle, then placing the data acquired by that lander into context with orbiter data so that its geologic context can be better charac- terized and understood. Curiosity Landing Site Localization: The Curi- osity landing was the first Mars mission to benefit from the selection of a science-driven descent camera (both MER rovers employed engineering descent im- agers).
