Gould, hoping to keep the strip evolving and changing with the times, slowly began changing the focus of the strip from a crime drama into one whose primary focus was science fiction. Tracy had always been equipped with the latest, most up-to-date police equipment, including forensic science, but with the introduction into the strip of eccentric industrialist Diet Smith as Tracy's friend in the 1940s, Tracy began to have the assistance of devices such as the two-way wrist radio, and later the two-way wrist TV.
The logical extension of this in Gould's mind was the introduction of space travel. Smith invented the magnetic-powered Space Coupe. With the use of this vehicle, Tracy and company landed on the Moon in 1964, finding there an advanced race of humanoids whose high technology meshed remarkably well with that of Smith's. The Moon race looked like Caucasian humans except for having abnormally large eyes and giraffe-like horns on their foreheads.
