Simulation of Dust Sedimentation on the Calibration Targets for the Surface Stereo Imager Onboard the Phoenix Mars Lander
Introduction: The Phoenix Mars Lander 2007 mission will carry three identical calibration targets to verify and validate the preflight calibration of the Surface Stereo Imager (SSI) and to monitor the stability of this calibration during the mission. The specially designed calibration targets (‘the caltargets’) are at least in one respect more advanced than calibration targets on earlier missio...
متن کاملA Revised Target Calibration Procedure for Imager for Mars Pathfinder and Surface Stereo Imager for Mars Polar Lander Datasets
Introduction: The Imager for Mars Pathfinder (IMP) returned over 16,000 high-quality images from the surface of Mars in 1997. The Surface Stereo Imager (SSI), a near duplicate of IMP on the Mars Polar Lander, will acquire images near the South Pole of Mars beginning December 3, 1999. Most scientific analyses of these datasets require some level of calibration , either into radiance units, or in...
متن کاملMagnetic properties experiments on the Mars Pathfinder lander: preliminary results.
Many of the particles currently suspended in the martian atmosphere are magnetic, with an average saturation magnetization of about 4 A. m2/kg (amperes times square meters per kilogram). The particles appear to consist of claylike aggregates stained or cemented with ferric oxide (Fe2O3); at least some of the stain and cement is probably maghemite (gamma-Fe2O3). The presence of the gamma phase w...
متن کاملPolarization Calibration of the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO)
As part of the overall ground-based calibration of the Helioseismic and Magnetic Imager (HMI) instrument an extensive set of polarimetric calibrations were performed. This paper describes the polarimetric design of the instrument, the test setup, the polarimetric model, the tests performed, and some results. It is demonstrated that HMI achieves an accuracy of 1% or better on the crosstalks betw...
متن کاملFabrication of Sulfate-bearing Ceramic Calibration Targets for the Chemcam Laser Spectroscopy Instrument, Mars Science Lander
Introduction: The ChemCam (chemistry/camera) instrument on the Mars Science Lander (MSL) images outcrop or regolith at high resolution and uses a laser source to generate high-temperature plasma from spots of ~100 μm diameter, at ranges up to ~7 m [1,2]. The lander will carry body-mounted calibration targets consisting of synthetic silicate glasses, a natural volcanic glass (macusanite), and fo...
