Bye bye, Tisdale. It's time to move on.
Next target? Philosilicates. ----- Edited on Sep 16 2011. This thread is dedicated to the exploration of Cape York, starting on sol 2703 when Opportunity left the "rocky garden" and started moving towards Chester Lake. |

True. It would be next to impossible to identify mineral makeup from pancam using the raw images from the web over only 11 wavelengths. Deconvolving spectra would be a huge challenge and would require data not available such as the CCD and electronics temperatures when the image was taken to enable proper calibration. The calibration target chips included hematite and goethite powder and were conditioned with UV exposure before launch, but after all this time could well have suffered from UV deterioration. I would assume that Jim Bell would have ensured laboratory spectra from expected minerals /combinations over expected temperature ranges using the actual deployed pancam to provide comnparative baselines. Certainly out of the amateur league.
But the Pancam and MI provide a huge amount of visual data and it is the correlation of all data that enables the production of the absolutely outstanding science papers we have become used to. |
