Isocyanate-crosslinked Metal Oxide-doped Silica Aerogels in Chromatic Calibration Targets for Planetary Exploration
Abstract
To generate photographs from the surfaces of other planets, imaging instruments need calibration standards that can withstand harsh environmetns while maintaining accurate color. These calibration targets much have low dust adhesion, resist chaning color or degradation in the presence of intense UV radiation, have minimal spacecraft or its instruments. The panoramic camera aboard existing Mars Rovers utilizes a moderately tacky matheral (RTV 655) for such chromatic calibration targets, in which dust readily adheres. Current investigations intruduce varying metal oxides as pigmentation into silica aerogels, which in a comparison to RTV 655, are much lighter weight materials which show little tackiness or dust adhesion while maintaining the desired pigmentation.
