The heart of the Constellation region of interest in the Reiner Gamma swirl. Astronauts exploring this region will address longstanding questions about the origins of this distinctive natural feature. Image width is 510 meters or 1673 feet.

First identified by early astronomers during the Renaissance, the Reiner Gamma formation has been a subject of intense scientific study for almost five decades and is one of the highest-priority targets for future human lunar exploration. Reiner Gamma is one of the most distinctive natural features on the Moon. The striking, tadpole-shaped swirl in WAC monochrome has a significantly higher reflectance than the surrounding mare basalts.

NASA's Goddard Space Flight Center built and manages the mission for the Exploration Systems Mission Directorate at NASA Headquarters in Washington. The Lunar Reconnaissance Orbiter Camera was designed to acquire data for landing site certification and to conduct polar illumination studies and global mapping. Operated by Arizona State University, LROC consists of a pair of narrow-angle cameras (NAC) and a single wide-angle camera (WAC). The mission is expected to return over 70 terabytes of image data.
