Elon Musk and his Dragon spacecraft, Richard Branson and his SpaceShipTwo, Paul Allen and his Stratolauncher, Jeff Bezos and his Blue Origin, Sierra Nevada and its Dream Chaser. And there is that slightly larger outfit known as the Peoples Republic of China, which is taking on space the way it has taken on pretty much everything else it has turned its attention to in the past 15 years and that means bigger, better and more ambitiously than anyone else on the block. Just this week, Branson gathered 300 of his citizen astronauts folks who have already plunked down deposits for $250,000 suborbital rides set to begin as early as 2014 for a sort of pep rally in a hangar in the Mojave Desert, with SpaceShipTwo gleaming on the tarmac nearby. The atmosphere was celebratory, and the prospective passengers seemed ready to go that very day. But will they be going at all next year, the year after that or even later? And what about all the other players, big and small, in what has become nothing short of a cosmic scrum? This is a look at where they all stand, in rough sequential order with special emphasis on the rough. In the 21st century space game, things change fast.
