The moon is a less aspirational subject these days, and, as the fiftieth anniversary of the Apollo 11 mission approached, I grew curious how contemporary children’s-book authors reckon with that now distant—old-timey, even—event.The recently published “My Little Golden Book About the First Moon Landing,” written by Chip Lovitt with illustrations by Bryan Sims, is perhaps the closest analogue among newly published books for “You Will Go to the Moon.” The text begins, “On July 20, 1969, two human beings walked on the Moon for the very first time. It is an amazing story!” There are other new books for kids that grapple more directly with the meaning of the Apollo program. “Rocket to the Moon!,” written and illustrated by Don Brown, is a witty graphic novel for slightly older kids that ends with a look back on Earth from space—seeming to imply that, if nothing else, the program gave us a quarter of a million miles’ worth of perspective on our home planet. Brian Floca’s “Moonshot: The Flight of Apollo 11,” a wonderful book, from 2009, that has been reissued this year in an expanded edition, ends by striking a similar there’s-no-place-like-home chord, showing us the Apollo 11 capsule splashing down safely in the Pacific, the astronauts returning “back to family, back to friends, to warmth, to light, to trees and blue water.” The most graceful evocation of this epiphany that I have found in a book for young people comes from “The Man Who Went to the Far Side of the Moon: The Story of Apollo 11 Astronaut Michael Collins,” which was written, illustrated, and designed (it includes photos, charts, and documents) by Bea Uusma Schyffert and first published in Sweden.
