These graben - a kind of trench that is formed as a surface expands - were imaged near a region of the Moon called Mare Frigoris by NASA's Lunar Reconnaissance Orbiter (LRO).
The LRO project is managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland, on behalf of NASA's Science Mission Directorate.
