I can't even begin to describe how psyched I get when I see demos like this. The advances that SpaceX and their competitors are making in terms of making access to space cheaper are what will eventually lead to the human species settling on other planets.<p>It also reminds me that when it comes to science, and who knows, maybe other things as well, it's not just public sector vs private sector. SpaceX wouldn't be driving us forward like this if NASA hadn't put in a whole heap of groundwork first, but similarly NASA have other goals to worry about besides keeping costs down. It's that combination of NASA's huge ambition and private enterprise's drive to make efficiency savings that will eventually get us colonizing places that aren't the Earth.<p>I hope it happens in my life time,
