“…On the basis of topography analyses results and the experiences of landing sites selection of previous lunar and martian landing exploration missions (Arvidson et al, 2008;Bridges, 2003;Golombek et al, 1997;Grant et al, 2011;Kirk et al, 2008;Quaide and Oberbeck, 1969;Wilhelms, 1985), we proposed two specific candidate landing sites for the future Chinese missions. These landing sites should have relatively low topographic slope (o1.01), small surface roughness (r1.0 m, LOLA RMS height), low rock abundance (o 0.5%, data from Bandfield et al, 2011), and low crater density (few large craters exist).…”
