Disgrifiad

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. The electronic interface is via the PanCam Interface Unit (PIU), and power conditioning is via a DC-DC converter. PanCam also includes a calibration target mounted on the rover deck for radiometric calibration, fiducial markers for geometric calibration, and a rover inspection mirror.

Disgrifiad lleygwr

The Aberystwyth University (AU) PanCam team is responsible for WP 5000: PanCam Calibration Target (PCT), Cameras Calibration, Fiducial Markers (FidMs), and the radiometric and colourimetric processing of the PanCam image data. This project continues the AU PanCam work funded by previous UK Space Agency grants. The objectives for WP 5000 for the period 01/12/15 to mission launch in may 2018 include: 1. Build, characterisation, documentation and delivery of PCT and FidMs Flight Models (FM) and Flight Spare (FS) models. 2. Prepare radiometric calibration plan and carry out calibration of the PanCam Instrument. 3. Prepare, test and document the algorithms (no software delivery - just algorithms) for implementation in the Data Processing pipeline at the Rover Operation and Control Center.
