On sols 4386-4388, NASA's Mars rover Curiosity conducted various observations and analyses in the Altadena quad.
The rover examined the amount of dust clinging to its calibration target, analyzed a small float block named 'Icehouse Canyon', and studied a DRT target on bedrock.
Curiosity also recorded the orientations of the long, linear veins in the area, observed materials on Gediz Vallis Ridge, and captured images of wind-sculpted structures called yardangs on Mount Sharp.
Furthermore, the rover performed sky observations to assess the amount of dust, search for clouds and dust devils, and measured chemical compounds in the Martian atmosphere.
