Mastcam mosaic from the Sol 1686 rover location looking behind the rover (downslope) at the transition point between the Sutton Island and Blunts Point Murray members. Images from Sols 1685-1689 display sedimentary textures of dark-toned manganese-rich sandstones and nearby rocks. Dashed line boxes in the large mosaic are shown as insets along the bottom of figure. Small red outlines show the approximate locations and extent of ChemCam observations. Throughout this transition area, dark-toned sandstones (presumably manganese-rich based on ChemCam observations at three locations) overlie light-toned materials. Insets from left to right: (a) Denning Brook, a manganese-rich fine-grained dark-toned sandstone ChemCam observation; (b) and (c) two light-toned blocks with cross-stratified textures, highlighted with yellow lines, 6 m away from Denning Brook and to the upper left in the large mosaic; (d) dark-toned materials (center of mosaic); and (E1) Newport Ledge, (E2) AEGIS post 1685a, (E3) Sugarloaf Mountain, three thin planar laminated dark-toned sandstones.

This Hubble image of the barred spiral galaxy UGC 12158 looks like someone took a white marking pen to it. In reality it is a combination of time exposures of a foreground asteroid moving through Hubble’s field-of-view, photobombing the observation of the galaxy. Several exposures of the galaxy were taken, what is evidence in the dashed pattern. The asteroid appears as a curved trail due to parallax: because Hubble is not stationary, but orbiting Earth, and this gives the illusion that the faint asteroid is swimming along a curved trajectory. The uncharted asteroid is in inside the asteroid belt in our Solar System, and hence is 10 trillion times closer to Hubble than the background galaxy.
