During the 1960s and 1970s, space exploration was everywhere, on the news, in the toys we unwrapped under the Christmas tree, in our favorite tv shows, and in our before-bed reading. Robert Silverberg was one of the deans of juvenile science fiction, presenting us with novel after novel about teenage boys caught up in outlandish outer-space adventures, with intense buddy bonds and girls barely mentioned. Good beyond hope.
I read them long after the publication date, and not in chronological order:
The Lost Race of Mars (1960), from my junior high library: a brother and sister living in a colony on Mars get lost, and are rescued by the Older Martians hiding in caves (because they know what happens to the aboriginal population when colonists arrive?)
Revolt on Alpha C (1955) came from Scholastic Book Club, catalogs that were passed out in class several times a years: you ordered up to five books, and they arrived a few weeks later (my parents disapproved of reading, so I claimed that they were all "for school"): On a colony on a planet orbiting Alpha Centauri, 20-year old Larry rejects his father's plans for his life and rebels against the Establishment. Groovy, man! The cover art, a boy floating through space upside down, was reminiscent of Will Robinson in the opening credits of Lost in Space.

Starman's Quest (1958): Twin brothers buddy-bond in space. The version I checked out of the Rock Island Public Library was generic, line-drawings of the two boys in space suits, with no Martian beefcake statue or muscle-suits.
