Apparently, NASA announced another announcement. Having recently proven the existence of flowing water on Mars, I think they’ve set the bar pretty high going forward. Here’s a story about the current status and findings of the New Horizons mission:
I’m thinking they’ll announce that either there’s flowing liquid (not water, possibly methane or nitrogen) on one of these bodies’ surfaces, or that they have enough data to say there’s a subsurface ocean.
Of course, I have no effing clue. Just a guess. What do you think?
