Four Frontiers

Three young men do what we all wanted to - they build Rocket Ship Galileo and fly it to the moon. Of course it's not so simple: there are rivals and red tape to overcome, and a totally unexpected and possibly lethal -- surprise waiting for them when they get there. Matt Dodson has heroic dreams of joining Space Patrol, so he becomes a Space Cadet and embarks on the long and difficult training that will show if he can do the job. His mettle is tested to the utmost when, on his first training flight he finds himself in the midst of an interplanetary crisis. Jim Marlowe grew up on the Red Planet, and when he's sent off to boarding school at Syrtis Major, he insists on taking his Martian pet with him. He doesn't anticipate how much trouble friendly little Willis will get him into -- and how paradoxically lucky that will turn out to be. Bill Lerner can't wait to leave an overcrowded Earth and become a Farmer in the Sky on Ganymede. He thinks he's ready for hard work and hardship -- but he has no idea what it will mean when things go wrong and the nearest help is four hundred million miles away!Includes:- Rocket Ship Galileo- Space cadet- Red planet- Farmer in the sky
