Synopsis

Seven expeditions have gone out to Callisto and never been heard from again.

History

First publication: Astonishing, April 1940

Asimov’s earliest written surviving story, but not the first in print.

Review

This story shows it’s place at the beginning of Asimov’s writings. The characters are very stock and the plot kind of formulaic. The science even Asimov admits is imaginary. Interesting only in being thorough about reading Asimov.
