Blue Bennu NASA/Goddard/University of Arizona. NASA’s OSIRIS-REx mission created these images using false-color Red-Green-Blue composites of asteroid Bennu. A 2D map and spacecraft imagery were overlaid on a shape model of the asteroid to create these false-color composites. In these composites, spectrally average and bluer-than-average terrain looks blue, and surfaces that are redder than average appear red. Bright green areas correspond to the instances of a mineral pyroxene, which likely came from a different asteroid, Vesta. Black areas near the poles indicate no data.
