What’s special isn’t so much putting people into LEO, so much as a private company having done it! It’s one thing for a nation-state to send a mission across the Atlantic or to the moon, but it’s a VERY different thing for companies to begin doing those things — developing rockets has always been enormously expensive, and this test (among others) signals that companies are finding ways to do it profitably. If this trend continues, we can probably expect the cost of a ticket to space to drop dramatically in the next 20 years. Wouldn’t it be amazing to visit other planets in our lifetimes?
