Overlapping petals of bright ejecta illustrate the complexity of ejecta emplacement, even in smaller impact events. The source crater is ~120 meters in diameter and lies on the floor of Murchison Crater, one of the Constellation regions of interest. Image size is 500-meter x 500-meter from LROC NAC frame M111599349RE; north is up [NASA/GSFC/Arizona State University].

High-resolution LROC view of part of the floor of Riccioli Crater, near the center of the Constellation region of interest. The view is centered on the boundary between a spur of the crater's central peak materials (lower right half of the image) and volcanic lava flow deposits (upper left half). The central peak materials are rougher and show a faint pattern of lines running NE-SW, suggesting that this terrain, like much of the rest of the crater, was scoured by ejecta from the younger Orientale impact basin to the southwest. Part of NAC frame M114444141LE, image width is 500 m and north is up [NASA/GSFC/Arizona State University].

Spectacularly preserved viscous flow on the NE rim of Byrgius A (19 km diameter) crater. This flow has a form similar to lava flows on the Earth - however it formed as a result of an asteroid or comet slamming into the Moon at hyper-velocity (>16 km/second). So much energy was released in the impact that solid rock was melted and thrown out of the crater where it flowed down the crater flanks (M102573276L, image width 810 m) [NASA/GSFC/Arizona State University].

Can we measure the size and shape of equipment and other objects on the Moon using today’s orbital images from LROC cameras? As an example, to demonstrate the precise 3D measurement capability of LROC NAC stereo imagery, three objects (including the Lunar Module, ALSEP equipment, and Turtle Rock) and the astronauts’ traverse at the Apollo 14 landing site are measured and their 3D models are reconstructed. Such 3D measurements and models are used for planning and designing future human landed missions to the Moon [NASA/GSFC/Arizona State University/The Ohio State University].

A contact between the dark basalt (left) of Mare Nectaris and the lighter anorthosite highlands (right) of Montes Pyrenaeus runs through the Constellation Program region of interest on the western rim of the Nectaris impact basin. Image width is 2.5 km, raw image resolution is 1m/pixel, NAC frame M104248025L [NASA/GSFC/Arizona State University].

A Constellation Program Region of Interest near the northeast edge of the unusually large melt pond adjacent to the lunar far side crater King. The boundary between the dark, coherent impact melt rock at the lower left of the image and the bright, pulverized ejecta blanket to the upper right is clearly visible in the floor of a smaller crater that formed at the boundary between these two units. Image width is 1.3 km, pixel width is 1.29 m. Subset of NAC frame M106088433R [NASA/GSFC/Arizona State University].
