Debussy quadrangle

Named after the Debussy crater, it was mapped in detail for the first time after MESSENGER entered orbit around Mercury in 2011.

It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated when Mariner 10 made its flybys in 1974 and 1975.

[1][2] In addition to the prominent Debussy crater, the western half of the Rembrandt basin is within the quadrangle.

Rembrandt is the second-largest impact basin on Mercury, after Caloris.
