100 Year Starship

The 100 Year Starship (100YSS) is a joint U.S. Defense Advanced Research Projects Agency (DARPA) and National Aeronautics and Space Administration (NASA) grant project to a private entity. The goal of the study is not to have the government fund the actual building of spacecraft, but rather to create a business plan that can last 100 years in order to help foster the research needed for interstellar travel.
