Discovered when Spurs Jackson and Hank Roper are kidnapped and sent to Venus by mad men who built the rocket ship. The trip is to test the rocket. If the experiment is successful, the rocket's builders will, according to Spurs, "make Venus their home and loot the Earth." Once they arrive on Venus, Spurs and Hank awaken, donning the space suits they discover on board. They leave the ship to explore the planet and attempt to find some intelligent beings to help them fly the rocket so they can home, as they do not know how to operate the spacecraft.
