Bill Nye offered his rationale for a more vigorous space program. Cassini finally explored Titan’s surface. A group is working on a “light sail” that we could use to travel through space more efficiently. And we wonder if Earth’s habitable atmosphere has to do with tectonic plates.

“Geysers on Europa like the ones on Enceladus would be, first of all, amazing. Second of all, if they’re there, they present us with an extraordinary opportunity to sample an ocean on another world without the enormous expense of designing a lander and propelling it out there. We can design a far less expensive mission that would (or will) fly through the spray of extraterrestrial ocean droplets and examine them remotely. These geysers were discovered just last year, so mission planners contributing to the Decadal Survey had no notion that such a mission was even possible.” Bill Nye on the Europa imperative SOURCE
