The large Rembrandt impact basin was discovered during MESSENGER's second Mercury flyby. A portion of the rim of that basin (outlined in red) is visible at top right in this high-resolution NAC image returned from the mission's recent third Mercury encounter. Two scarps (cliffs) can also be identified in this image (yellow arrows); both scarps cut across craters that have been deformed by the faulting that produced the scarps (blue arrows). Because this area of Mercury's surface was imaged during both MESSENGER's second and third Mercury flybys, there is now stereo coverage that enables a three-dimensional visualization of the surface to be constructed. Information about the surface topography is valuable for MESSENGER scientists working to decipher the geological history of Rembrandt basin and these neighboring scarps. "The tectonics of impact basins on Mercury" is one of the topics presented by MESSENGER Science Team members at the Geological Society of America Annual Meeting.
