The basic truth is, the vast majority of people couldn’t give less of a fuck about space and space exploration.

It’s just too abstract, too complicated, and too far away for them to feel connected to it. It’s not attached to national pride (anymore), it’s not connected to tragedy (typically), it’s not connected to celebrities they feel like they know (Katy Perry isn’t involved with this launch)… there’s just nothing for the average person to connect with.

Every other explanation is just an excuse from people who feel like they should care, but never have.
