“Into the Darkness” is a short story that I believed showed up in one of Asimov’s collections. I don’t know the author or which collection (although it seems to me it was a low number).

The Internet Speculative Fiction Database (found at http://www.sfsite.com ) lists “Into the Darkness” by Ross Rocklynne, published in two different Asimov anthologies. Publication history is below:
