Robert Heinlein's vision of space travel and the future of man are depicted in his second cinematic space travel adventure, his first being "Destination Moon" three years earlier. Colonel Breiteis, a female rocket pilot, and Major Moore, her co-pilot, are selected to orbit the Moon to survey a landing area for a future expedition, but a ruthless Russian spy-scientist aboard the ship causes it to land on the lunar surface, stranded and out of fuel. Will they live or die in these dire circumstances' Writer Heinlein gives us thrilling ideas of an orbital space station where people walk on the walls and ceilings, a rocketship that looks much like the real one that landed on the Moon in 1969, the American Space Force, commie spies and a woman President of the United States.
