Derain quadrangle

Named after the Derain 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.

The large Lennon-Picasso Basin covers much of the eastern part of the quadrangle.

[3] An unnamed basin (b36) of 730 km diameter underlies the craters Derain and Ellington.

[3] The most prominent characteristic of the basin is the remant of the western and southern rim.
