New Horizons Day 2: Liquids on Pluto's surface?
Posted by Emily Lakdawalla on 2011/09/13 01:27 CDT
Jeff Moore's presentation was cool because of the discussion it stimulated. He considered what exogenic processes might be operating on Pluto's surface. What's an exogenic process? It's something that modifies the shape of the surface from the outside, and doesn't require the body to be geologically active inside.
