It hasn't been very well marketed. NASA lost a lot of their budget and they're not spending so much on outreach. I didn't know it was happening at all until launch day.
They should be spending exactly $0 on marketing. They're sending people around the moon in a giant rocket ship. It sells itself.
It actually doesn't. It didn't even "sell itself" the first time. Apollo required a massive national propaganda campaign framing the space race in terms of an existential war against communist annihilation to get people to even care - and people still stopped caring once the news stopped being sensational.
