Europa may get a mission...eventually. We give our first take on the 2015 NASA Budget request. How does Planetary Exploration fare? Which projects were cancelled? Will NASA capture an asteroid? And most importantly, what can you do about it?

It's time to reassess Europa exploration, past, present and future. The Destination Europa! session at AGU, inspired by the eponymous website and movement, didn't take exactly that message as its theme, but it's what I got from the presentations. What an ELECTRIFYING meeting this has been for Europa exploration!
