Cosmic Yo-Yo by Ross Rocklynne appeared in the Summer 1945 issue of Planet Stories.
The Cosmic Yo-yo is a fairly short Blue-collar space romance by Ross Rocklynne. This one was panned a bit in the letters to the editor in the following issue, partly because of its rather silly premise, but I actually really liked this one.
A couple of asteroid haulers have created a business out of convincing rich folks on Earth that it would be great to have asteroids in their back yard. Truly the gift for someone who has everything! Of course, they’ve also got rivals who’ve taken their idea and are in heated competition.
The Bubble Dwellers by Ross Rocklynne appeared in the Fall 1945 issue of Planet Stories and was one of two ‘novels’ in this issue.
The Bubble Dwellers was definitely one of those fantastic stories that makes the pulps worth checking out. An evil hypnotist, strange humanoids with a mystic connection to their once glorious past, and bad-ass beauty worth risking life and limb for are all to be found on a hostile alien world of mystery.
Sidney Hallmeyer and Will Carrist are having a smoke, drinking coffee and waiting to die. The heat shielding on their ship just isn’t strong enough, and they’re going to burn up just like the previous two missions sent to research magnetic fields on Mercury and emanating from the sun. Just as they’re about to shut off their life support and cooling systems, Sid and Will receive an SOS through the solar static coming from a hitherto unknown planet Vulcan.
Doctor Roberto Zondat, a notorious criminal who had to flee earth after hypnotizing several millionaires to write him into their wills then commit suicide, has holed up on the tiny fiery world of Vulcan. Zondat intends to establish an empire in the hollowed out magma chambers with the help of enslaved natives. Edith Dupre, a space-racer who had gone missing a few months before and been stranded on Vulcan ever since, managed to escape the grubby mitts of Zondat and his henchmen to put out the call for help.
