About this puzzle
The space age moved faster in its first two decades than most people remember, then slowed down considerably - which is why launch years cluster in ways that feel wrong. Twelve years separate the first satellite from a crewed Moon landing, while later milestones like a great orbiting telescope and a permanently crewed station are decades apart. Fame is no guide to chronology here: the most famous mission is not the earliest one.
