  None if it was common 100 years ago even 'just'. Maybe indoor plumbing - but that was only 'kind of common' in the cities, not in rural areas, and cities weren't even quite half the population, tipping point for even that wasn't for a few more decades. Radios were just starting, they were not common. Space flight is not the significant 'thing' of the 20th century. It's just an experiment. We are not going to colonize Mars or travel the Solar System in any meaningful way for a long time. Life on Mars would be brutal and inhumane - locked in a dormitory forever? We will put a few people there, but that's it probably for many decades. We could have feasibly done this on the Moon already - we haven't because it's just too expensive for not much benefit. Maybe mining some asteroids. Otherwise, nothing hugely meaningful is going to happen in space, it's just too empty, too difficult and the benefits are marginal. Meanwhile on earth, the pace of 'change' is nothing like we've seen it before.
