I spotted the cover of a Fantasy and Science Fiction magazine from 1961, and was intrigued by the strange looking ship on the cover. Like a lightbulb with spindly legs. It looked ideal for my current experiments with Vue, and a model came together rapidly.
A ‘sand storm’ Vue atmosphere made for a suitable Martian dust storm, and I soon had the brown image you see here! RB-1 is a reference to Ray Bradbury.
I decided to try some other atmospheres, and was pleased to rapidly find another that seemed to work well, but in a different way. It was intended for use on a planet orbiting a dwarf star.
