This story is about colonization on Ganymede started because earth's population was too large and there wasn't enough food. So with lots of hard work, a few rock crushing machines, imported earthworms and other soil bacteria but no weeds (great idea) they manage to create arable farmland. An e=mc² converter supplies sufficient power to create a heat shield and several other technologies create a breathable low-pressure atmosphere.
Social interactions, political commentary, technology, and survival techniques - perhaps it could have been an early version of a Reality show (which I wouldn't have seen since we didn't have a TV set).
The top cover is on the copy of the book I took out from the library; the bottom one is the 1950 version and was on my copy.
