Why Inspiration4 mission means for future of human spaceflight more than it looks like
With the fully private mission of SpaceX Dragon spacecraft, we probably will see a much bigger interest in human spaceflight from commercial sectors. A flight to space won't' be very cheap in close perspective (at least aboard Dragon spacecraft) but it probably will be cheaper than it was from NASA. But this mission will move human spaceflight from awkward governmental machine to fast iterating commercial sector. And that's why it's a really big thing.
