'Blueberries' Inside 'Popcorn'
January 10, 2005
This view from the microscopic imager on NASA's Mars Exploration Rover Opportunity shows a type of light-colored, rough-textured spherules scientists are calling "popcorn" in contrast to the darker, smoother spherules called "blueberries." It is the lower-left frame of a four frame mosaic [15-ZL-04-MI2-B202R1] taken on sol 199 (Aug. 15, 2004). Blueberries and fragments of blueberries appear to be inside some of the popcorn pebbles.
