This mosaic was acquired by the Mars Exploration Rover Opportunity on Sol 4335 (April 3, 2016). This approximately 100 degree view shows an outcrop atop a ridge near the west end of Marathon Valley. This location is Opportunity's first "station" after passing Knudsen Ridge that displays from orbit strong spectral signs of clay minerals. The New Mexico Museum of Natural History and Science explains more in their Rover Field Report from Sol 4365 in early May 2016. Shown here as blue in false color, the valley floor of Eneavour Crater is visible in the left topmost frames. NOTE: Missing data and other artifacts in this mosaic are the result of the images being acquired while the Opportunity rover was operating in "RAM mode". That is, because of issues with the rover's onboard Flash memory storage, sometimes data are stored directly in the rover's volatile RAM memory instead, and then downlinked to Earth. At the end of each sol of RAM mode operations, however, when the rover shuts down, all of that sol's data is erased. Thus, any missing images, missing color channels, or data transmission errors cannot be fixed by retransmitting the missing data the following sol, like we can do during Flash mode operations.
Pancam's 753nm, 535nm, and 432nm filters were used in making this mosaic. Two versions are provided at full resolution: an approximate true color rendering, and a false color rendering which enhances the subtle color differences in the scene.
