They have targeted a landing site in the Ma'at region on the "head" of the comet, in a flat area adjacent to a pit from which Rosetta has seen cometary activity. During the descent, they hope to observe at very high resolution the "goosebump" structures in the wall of the pit that they think may be a record of how the comet formed by accretion of smaller cometesimals. The team has named the pit Deir el-Medina for its resemblance to the Egyptian archeological site. Deir el-Medina is the site labeled "Ma'at_02" in the image below. Simulations of the landing suggest they should be able to touch down in that flat area between the sites marked "Ma'at_02" and "Ma'at_03" (within a region 500 by 700 meters in size).
