Bad-boy Pentagon boffinry bureau DARPA has now released the official solicitation for its "100 Year Starship" project, intended to get human beings making interstellar voyages within a century.

We've covered the 100 Year Starship push on these pages before, and the outline idea remains the same. A very small amount of US government seed money (to be specific, $500,000) will be provided by DARPA and handed out by NASA's Ames campus in Silicon Valley. This tiny financial seed is intended to sprout and grow into a stupendous organisation able to harness and deploy the titanic resources necessary to deliver working interstellar transport.
