Grooves  << back to mosaics


         This mosaic was acquired by the Mars Exploration Rover Opportunity on Sol 4460 (August 10, 2016).  About 78 degrees wide, the field of view in this mosaic is of what looks like could be water carved grooves. 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 753 nm, 535 nm, and 432 nm filters were used in making this mosaic.  Three versions are provided at full resolution: an approximate true color rendering, a false color rendering which enhances the subtle color differences in the scene, and a stereo anaglyph for 3D viewing through red-blue glasses.
