Finally! New Horizons has a second target

Posted by Emily Lakdawalla on 2014/10/15 01:02 CDT | 17 comments

What a huge relief: there is finally a place for New Horizons to visit beyond Pluto.

With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa 2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.
