Moon Ahead

This is a pretty standard boys adventure from the 1950's. Two kids in Australia end up on a trip to the moon along with their dads. I read it on archive.org. Unlike many such books from the period, this put a lot of effort to be accurate. It was published close to 20 years before the first moon landing but a lot of it's descriptions of being on the moon were pretty good.
It slows down a bit when the author gives lectures on cosmic rays, collision probabilities, celestial mechanics and other topics, but this is the fun part because it's so rare in SF stories of the time to get any of this right.
I had fun reading it and reccomend it if you lie 50's SF
