The Quest of the Chlorophyll Monsters: The Earth is under attack by aliens using special rays. They are using the rays to extract chlorophyll from the Earth's plants. Some men from Earth go there and eventually there is a space battle. The story ends in a win-win scenario for both sides.

Space Race: Manned rocketships race from the Earth to Pluto and back. One ship has a female co-pilot and the crew of another ship think that is bad luck. There is a big gambling crook that has bet against the ship with the woman on board and has a bunch of thugs all over the place to try to stop the ship.

A personal robot one guy has does not want him to go to the moon because the ship has a flaw.
