The International Astronomical Union (IAU) recently approved a proposal from the MESSENGER Science Team to assign names to 10 rupes, the long cliff-like escarpments that formed over major faults along which one large block of crust on Mercury was thrust up and over another.

In keeping with the established naming theme for rupes on Mercury, all of the newly designated features are named after ships of discovery. [more]
