Now they are looking at long-terms plans for man to get from here to Alpha Centuri, the nearest star system. The problem; well, it's a bigger hike than you might imagine. Take this analogy, presented by starship designer Richard Obousy:
If Earth were in Orlando and the closest star system, Alpha Centauri, were in Los Angeles, then NASA’s two Voyager spacecraft, the most distant manmade objects, have traveled just one mile.Wow. From that factoid you might think there's no chance. But these diligent folks are working on a number of interesting ideas involving nuclear powered engines (like the Icarus project, pictured above which is the size of an aircraft carrier) and a starship that has no engine at all. That ship would travel using the gravity of asteroids, planets and stars along the way, not unlike the Voyager crafts. But the timeline they're working on here, of course, is a long one...100 years long. So though I'll likely never see it in my lifetime it's fascinating stuff to ponder anyway.
