Eastern slope (right to left is downhill) of the Vallis Schröteri, "Cobra Head". This feature is located in the western portion of a Constellation Program region of interest on the Aristarchus plateau. The slopes of the Cobra Head are boulder-rich and display albedo variations - bright to dark. The patterns of debris and flows on the slopes are evidence for mass-wasting and landslides that expose a variety of rocks. Image width is ~0.5 km, pixel width is 0.51 meters, NAC frame M111918050R [NASA/GSFC/Arizona State University].

A lobate scarp in the mare basalts of Aitken crater on the lunar farside (arrows). Aitken crater is one of the fifty regions of interest in NASA’s Constellation Program. The smooth mare basalts that flooded the floor of Aitken crater are relatively few on the lunar farside. Mare basalts often have wrinkle ridges and lobate scarps, tectonic landforms that express contraction of the volcanic flows. Future astronauts who might visit Aitken crater will explore this landform in search of clues to how this and other lobate scarps form. Image width is 4.5 km, NAC frame M103374879RE [NASA/GSFC/Arizona State University].

A very subtle mare-highlands boundary in Mare Moscoviense on the lunar farside, near the center of the Constellation Program region of interest. The generalized geologic contact between the mare and the highlands has been highlighted (mare to the left, highlands to the right). Astronauts exploring this region could collect key samples from the farside basalts of Mare Moscoviense as well as materials from the surrounding basin massifs. Image width is 1.8 km [NASA/GSFC/Arizona State University].

A junction between the rims of three craters on the floor of Peary crater near the lunar north pole is evident in this NAC image (M101955359L). Note the mottled texture of the regolith. Peary is a key exploration site for future astronauts due its proximity to potential resources. Image width is 2.68 km [NASA/GSFC/Arizona State University].

Seeing small areas of the Moon at 50 cm per pixel often presents unexpected views, and sometimes it is hard to interpret the geology at first glance, much less what is up and what is down! What are the white streaks? How did they get there? Image is 600 meters wide, from NAC frame M109624226L [NASA/GSFC/Arizona State University].
