Armstrong On Luna

Sf has had many "first men on the Moon." Wells had Cavor and Bedford. Heinlein had three such stories:

his Future History version;
his Scribner Juvenile version;
his film version.

CS Lewis wrote "Forms of Things Unknown." (See here.)

Poul Anderson wrote "The Light."

Since 1969, sf writers can instead refer to the real first Moon landing. The Chronology of Jerry Pournelle's Codominium future history begins with it and, in Anderson's The Avatar, a wall in the space Wheel has "...a photomural, Armstrong on Luna..." (XIX, p. 170)
