SpaceX - Falcon Heavy

That was about the coolest thing I've seen. Just watched the SpaceX Falcon Heavy make history. That simultaneous rocket landing was so neat. This makes me hopeful for the future when we can put aside our petty differences and focus on humanity's place in the cosmos. We need to expand into space. We need to take this stepping stone and keep pushing our knowledge and science farther, because advances in space technology will help us on earth, too.
