One of my favorite subgenres of science fiction is space/space opera. Probably because growing up I caught just about every Gemini and Apollo launch/spacewalk/moon landing/splashdown that I could (and I have now dated myself). I pulled this from the TBR pile, a book I picked up sometime back from the now closed Know New Books in Palo Alto.
Some facts. The book is aimed at a YA audience and published in 1952, and that does make it dated in some aspects (finding life on other planets in the solar system). Blake Savage is a pseudonym used by Harold Goodwin a writer of popular science books (per my quick research). Under another pseudonym he wrote the Rick Brant science adventures a competitor of the less scientific accurate Tom Swift Jr. books.
With the background out of the way the book's biggest minus is that there are no female characters. That could be a plus when you think about the standard portrayal of female characters in most of the YA science fiction I was able to find growing up (at least I think the sexism is reduced in the 2000s). Yes, science he references is outdated at time, but that is always the risk in reading science fiction (I laughed while reading Neal Stephenson's Cryptonomicon when one character was inserting a floppy disk into his laptop). That doesn't mean this book isn't enjoyable (as was Cryptonomicon).
The book's strengths are when it tries to stay close to science fact. While not handled in detail there is acceleration, deceleration, course corrections, ship design, etc. talked about in a way that I don't would have been condescending to the kids of the 1950s, and from working as a library volunteer at a hospital possibly over the head of some of today's children. An attempt is made to have a diverse cast, slightly stereotypical, but diverse. Our characters includes Americans, Mexicans, Chinese, Scots, and one of the last 17 pure blood Hawaiians left on Earth.
Another plus is that the lead character Foster, combines the supreme confidence of youth, as in being a recent academy graduate, and some signs of growing up. He doubts that he has made the right decision at times (of course he gets away with all of his decisions), and he realizes that people's lives rest of his making the correct call.
The plot is pretty basic. Get an asteroid made of Thorium from the asteroid belt to the Earth's orbit. Of course they manage it, but the methods used are reasonable for the time period the book was written,
