The moon's Marius Hills region is known for its diverse and complex volcanic features: extensive mare basalt plains, small shield volcanoes, steep-sided cones possibly constructed from cinder or spatter, and sinuous rilles.
One of these rilles has a small (approximately 50 m in diameter) pit in its floor, possibly a skylight opening into a lava tube. Today's featured image is a low-sun angle controlled mosaic of part of the Marius Hills region created by combining three image pairs with similar lighting conditions (acquired on adjacent orbits). To create an accurate mosaic, a control network is used to tie the images together and correct for camera pointing and spacecraft position over the lunar surface (refer to the RDR description for more details). Today's featured mosaic illustrates all the major volcanic landforms found in the Marius Hills.
