Putting together the puzzle of the future of our presence in space. There are so many pieces that will form our future: The X-Prize, all of the X-Prize contenders individually...especially Scaled Composites & The Da Vinci project, the new space elevator contest, Bigelow's(sp?) inflatable habitat, Nasa's possible Moon to Mars vision, and Nasa's future prizes are just some of the puzzle pieces off of the top of my head.<br /><br />What will all of this lead to? How long untill suborbital tourist flights? Orbital flights? Space Hotels? What will come of the Moon to Mars vision? In...I don't know, 10, 15, 25 years what will everything look like? Any predictions?
