To think - not too incredibly long ago we missed Mars. Now we're sending crafts to hit a moving comet?! Incredible. This is what science fiction movies are made of. Think of the advancements that we'll have in 50 years from now.
I'm glad to be alive during this time period. Granted, there's a lot of shit going on..but mankind is certainly exploring like never before. So many amazing breakthoughs in technology during just the last 100 years. The next 100 should be equally, if not more, mind-blowing.
