Done With This Dune

The Core of Purgatory Ripple
Pasadena CA (JPL) Jul 13, 2005
Opportunity spent the past week positioning itself for robotic-arm work and studying the area at the base of "Purgatory Ripple." The rover has examined its tracks (which contain material carried out of Purgatory Dune by the wheels) and undisturbed dune material.

Sol-by-sol summaries:

Sols 503 and 504 (June 23 and 24, 2005): Opportunity drove partway to the position for robotic-arm work on Purgatory Dune. Remote sensing over these two sols included a panoramic camera image of the robotic-arm work volume, a navigation camera panorama, and a miniature thermal emission spectrometer raster.

Sol 505 and 506: Opportunity acquired two microscopic imager mosaics and an alpha particle X-ray spectrometer integration on soil before a short drive to the position for examining the tracks.

Sol 507: This was the first of three days using the robotic arm at Purgatory Dune. The rover completed two microscopic imager mosaics and an alpha particle X-ray spectrometer integration. Opportunity also fired up the miniature thermal emission spectrometer for an afternoon raster.

Sol 508: The rover completed a 24-hour Moessbauer integration and collected more data with the miniature thermal emission spectrometer.

Sol 509 (June 29, 2005): Opportunity collected data with the alpha particle X-ray spectrometer and made a late-night observation of the dune with the miniature thermal emission spectrometer.
