DARPA 100 Year Starship Solicitation Announcement
"The 100 Year StarshipTM (100YSSTM) is a project seeded by the Defense Advanced Research Projects Agency (DARPA), with NASA Ames Research Center as executing agent, to develop a viable and sustainable non-governmental organization for persistent, long-term, private-sector investment into the myriad of disciplines needed to make long-distance space travel viable. The goal is to develop an investment vehicle--with the patronage and guidance of entrepreneurs, business leaders, and technology visionaries--which provides the stability for sustained investment over a century-long time horizon, concomitant with the agility to respond to the accelerating pace of technological, social, and other change."




The day someone can convince me of a compelling business case for private industry to invest in ANY beyond Earth orbit, long-duration exploratory/scientific mission...is the day I will become a believer.
Until then, Commercial Space will be ruled by the almighty dollar (nothing wrong with that, per se), and will be limited to LEO commercial and government satellite launches, and possibly millionaire/billionaire space tourism.
