Every few years in comics, there's a short-lived never-reprinted sci-fi space adventure series...
In the 1960s it was Gold Key's Explorers in the Unknown.
In the 1970s, it was DC's Space Voyagers, appearing in the back of Rima the Jungle Girl.
Though this is the origin tale, it appeared in Rima the Jungle Girl #3 (1974), after a two-parter (set after the events of this tale) ran in #1 & #2!
(Oddly, the pilot episode of the Classic Star Trek tv series, "Where No Man has Gone Before", aired as the third episode of that series.)
Scripted by Robert Kanigher and illustrated by Alex Nino, the series ran thru the first five issues of Rima before disappearing.
