Figure 1. (a) The InSight lander (red box) in the 27
m-diameter Homestead hollow degraded impact crater (red dashed
circle) in western Elysium Planitia, Mars (4.502°N, 135.623°E). The
lander is 6 m measured across the solar panels, is in the northwestern
quadrant of the hollow, and the lander workspace is to the south. Yellow
box shows location of (b). Subframe of HiRISE color ESP_036761_1845
(0.25 m/pixel). (b) Color view of InSight lander inHomestead hollow (red dashed circle) and other hollows (white
dotted circles) in the immediate vicinity. Red line cutting across the
hollow is the boundary between occurrence of relatively few rocks to the
east versus ~3X more rocks in the region to the west
dubbed “Rocky Field ” (see Figure 2). Landing rockets removed
dust from the immediate surface and caused the bright zone and
surrounding dark halo around the lander (Williams et al., 2020).
