(on first viewing my retinal scan at Simpsons Optometry, Civic, ACT)
from orbit the wide-field camera
images buttes and arroyos
drainage basins to dark arterials;
side-scanning radar returns runs of rods and cones,
the (im)maculate macular,
the plunge over the great dark spot
deeper than Everests inverted.
A territory shaped of moving water + dust.
And for your enjoyment the thin white duke with Life on Mars from 1971. In the same year that green suits were a thing, the space race targeted Mars: the then USSR launched two probes (Mars 2 & 3) in mid-May and the US launched Mariner 9 on 31 May.
