Art by John Polgreen for the book “Space Travel” by Willy Ley. Poughkeepsie: Guild Press, (1958).
Expedition to planet Mercury’s “Twilight Belt,” which separates the super-heated hemisphere that always faces the sun from the frozen hemisphere that always faces away. The Twilight Belt will have “liveable conditions, if only in the sense that it will not get too hot or too cold. From a station in this zone quick exploratory trips could be made to both hemispheres.” [Quoting from the text]
