The researchers identified significant geologic features of the Schrodinger basin, located near the lunar south pole. Schrodinger is the second-youngest impact basin on the moon and includes diverse crustal features and rock types that are important to understanding the moon's geological history.

"When the Schrodinger basin was formed, some of these lithologies (the general physical characteristics of the rocks) may have been uplifted from very deep below the lunar surface," Czaplinski said. "Therefore, investigating these rocks up close is extremely important for answering high-priority science goals."

In 2007, the National Research Council outlined scientific objectives and goals of future lunar missions, including exploration of the South Pole-Aitken basin, the oldest and deepest impact basin on the moon. Because the Schrodinger basin is located within the South Pole-Aitken basin, it presents a unique opportunity to study rocks that possibly originated deep below the surface, Czaplinski said.

"Many of these rock types are exposed at the surface in multi-kilometer long exposures of rock outcrops in Schrodinger's 'peak ring,' an inner ring of uplifted rocks that formed with the basin. Sampling these rocks within the peak ring provides high scientific potential for further understanding the context of Schrodinger's lithologies."

Along with the map, researchers created three potential paths for robotic rovers to travel through the Schrodinger basin to collect high-priority rock samples.
