I've said it before, but I firmly believe that investing in space exploration and development holds the key to our future as a species. earth can only do so much. Colonizing and exploring new planets and worlds will provide tens of millions of new jobs in all sectors. Mining, here on earth and on mars, asteroids, who knows. Manufacturing, to build prefab housing and stuff. Not to mention the rockets to get them, stations, who knows what else. And high paying jobs those are too.
But then I see people who complain about NASAs budget saying all that money is going to waste. Tsk.
