Lovely Lichtenberg B
Lichtenberg B is a beautifully preserved young impact crater. Rock outcrops in the upper portion of the crater wall are due to the successive thin lava flows that filled Oceanus Procellarum more than 3 billion years ago. The crater is...

Tadpole and Lava Tube
An irregularly shaped depression, resembling a tadpole (center left), which is part of a sinuous chain of pits. The black arrow indicates the beginning of the pit chain that trends to the southeast. This feature is about 8 km long and...

Mare Pit Topography!
The crisp morphology of the central Mare Fecunditatis pit (white arrow) stands out in elevation data and suggests a relatively young age. This pit is about 200-m in length and 45 m deep. Image width is 5 km; north is up. Color...

Striped Crater
Dark mantle deposits decorate a crater wall. Slowly pulled downhill by gravity, the volcanic glasses that compose these stripes where formed during explosive volcanic eruptions on the Moon. The scene is 952m wide from NAC image...

Frozen Motion
The scoured floor of Harkhebi J crater, near the young crater Giordano Bruno (22 km diameter). Ejecta from Giordano Bruno flowed across the surface, leaving a record for us to see today. LROC NAC image M1128791817L; north is up and the...

Littered Wrinkles
LROC NAC image M1144863959L of portion of a wrinkle ridge found in Mare Nubium. The crest and side of the ridge is lined with high reflectance boulders, likely eroded from the fractured basalts that make up the ridge. Image width...

Fresh, But Not So Clean
LROC NAC image M131515002R showing two similarly sized craters, ~500 m in diameter, but one is littered with boulders and the other is not. This boulder discrepency is most likely due to age differences between the two craters....

A Tortuous Path in Posidonius
This may look like a work of abstract art, but in reality, it's for science! This colorful image is an LROC slope map of the northwestern portion of the floor of Posidonius crater. Warmer colors indicate steeper slopes, whereas cooler...

Making a Splash at King Crater
Impact melt ponds adorn the lumpy terraces of King crater. If you look carefully, you can see small fractures in some of the these ponds. LROC NAC mosaic (M1159315479L/R), image width is approximately 8 km [NASA/GSFC/Arizona State...

Small Step or Giant Leap?
A house-sized boulder (more than 30 m in diameter) left a clear impression (arrow) in the lunar surface. This boulder was thrown a relatively short distance (500 m) to the east of a young 1.6-km crater (rim crest to the left); LROC NAC...

Dorsum Nicol
This tectonic feature was formed as stresses built up in the lunar crust until the rock gave way. The energy released was immense, and the displaced rock is the north-south trending wrinkle ridge that we see today. This is LROC NAC...

Birt E
Birt E crater is thought to be the source region for lava that carved out Rima Birt, a rille in Mare Nubium. This mare is older than 3.4 billion years, and so is this vent! LROC NAC M1144849711LR with the a color DTM overlaid; North is...

A Rille to Rover Over
LROC NAC image M1145219838 of a rille found on the Southwestern edge of Oceanus Procellarum. This rille most likely formed from the stress added to the crust as the mare deposits were emplaced and cooled [NASA/GSFC/Arizona State...
