I don't think that knowing about the achievements of Yuri Gagarin or John Glenn are "trivia". The Russian space program was shrouded in secrecy until after the fact, so that was a detriment, but every single US launch that was televised was an "event" at my little back-woods elementary school. The whole student-body would gather along with all of our teachers (and even the janitor and the cook, if they were still in the building) to watch the launch on the B&W (duh! no other kind, then) TV, and quite often our teachers would have some kinds of activities planned for us that tied into the launch.
I knew when I was young that the Earth's atmosphere got thinner and thinner the higher you went in altitude and I idolized test pilots (exemplified publicly by Chuck Yeager) who were brave enough to strap into a glorified little "flying needle" like the X-15, get a ride to the altitude-limits of the capabilities of a B-52, and get dropped off so they could take a trip to "outer space". It ain't trivia if you lived through it, and were expected to learn from it.
Want some more "trivia"? After Sputnik, US school-kids were given banks of aptitude tests and IQ tests to identify potential high-achievers who could be routed into science and technology curricula later, to help the US dominate the space race. My parents were very poor, and my sisters and I had pretty meager "hauls" on Christmas, not unlike many of my friends in that area. However, the year of our first round of evaluations I got a cheap but usable Newtonian telescope for Christmas (the ball-mount was a *****!) and the next year, I got an Edmund's microscope with 3 objectives and a couple of eyepieces. In another year or so, my father managed to scrape up enough money to buy a set of World Book encyclopedias.
