Secret of the Red Spot

SPACE ENIGMA--WHAT WAS THE SECRET OF THE RED SPOT?

The chrono-calendar chart of Jay Bruce's spaceship read May 23, 2440 A.D. The sky around him as an impenetrable blanket of opaque gas, typical of this region on Jupiter north of the Red Spot.

Bruce was puzzled. Why had the lovely young woman seated next to him chartered his ship to cruise an uninhabited area?

Then it appeared...a massive Martian warship unlike any he'd ever seen before, forcing him to land--and perhaps to die--in the barren Jovian wilderness.
