Philae’s ROLIS camera acquired 6 images of the surface of 67P after the final landing. Illumination of the comet surface was provided by LEDs of four colors. A local horizon is visible in one image corner, beyond which we can see the coma. Seen at low phase angle, the comet surface displays a bimodal brightness distribution. The surface seems to consist of plates with a consolidated crust, separated by cracks.
