“After a Judgment Day,” Edmond Hamilton, 1963 — Fallout has mutated harmless bacteria into the A-Plague, which wipes out humanity. Five men on a lunar outpost have been engaged in sending out “cyborgs” to explore various planets. Three return home immediately to die with Earth; two remain with the cyborgs. Before returning home, one man insists on preparing a time capsule documenting Earth culture so that a copy may be sent with the cyborgs.
Comments: The title is from a poem by G. K. Chesterton. Read in Best of Hamilton.
