Journey to a Moon Village is another of the Christian children's space books I have found. I sure there were not a lot of these but they are interesting in bring together space age excitement and Christian values.
Pyle, Pacheco. Journey to moon village. Springfield, MO : Gospel Pub. House, 1963. (60 p.) 19 cm, 1963.
The story is about how a boy discovers a friendly preacher and his message while they take care of the bad guy : "Dirty Curtis."
