This is the first step towards actually getting to another habitable planet before our local star (the sun) burns out [in about 3bn years time as an estimate], preferably one that's both young in it's life and not yet inhabited by intelligent life, though not so young that it's still settling down. Potentially, in about half a century (or half a millennium depending on how much research actually goes into it and how successful it is), we might be able to see what's outside the Milky Way. Yes, outside the galaxy. At the very least i'd expect us to leave the local solar system.
I've no doubt this will be all we hear about it for at least a decade or 2 though
